LFP™ Chemical Spray Shields

We all know how annoying it is when the pipes under your bathroom sink spring a leak: ruined toiletries, soaked towels, and a big bill from the plumber.  Now imagine if you owned a piping system that didn’t carry water to the sink, but corrosive fluids under extremely high pressure. When these systems leak, you have to worry about more than just buying a new hairdryer.  
At Firwin, we provide our customers with custom manufactured chemical spray shields that offer innovative spray and leak containment from accidental gasket ruptures. Unlike our competitors, our LFP™ Chemical Spray Shields are made of a non-porous, all PTFE material that guarantees performance against harmful spray-out and leakage no matter the severity or duration of chemical exposure. Our LFP™ shields can handle temperatures from -100F° to 550°F. In addition, they can be used in almost any industrial setting, including pharmaceutical, gas and oil, offshore, marine, chemical processing, FDA approved, cryogenic, and clean room applications. Just in case that isn’t impressive enough, LFP™ also won the 1995 DuPont Plunket Award and Chemical processing’s Vaaler Award. 
 With all the benefits of our LFP™ Chemical Spray Shields, it should come as no shock that a multi-national gas company headquartered in the Middle East recently approached Firwin to help them complete a new processing plant.  The customer ordered almost 700 custom spray shields in a wide variety of sizes for use throughout their plant.  Over a period of six months, we worked hand in hand with them to make sure that every one of our spray shield fit and functioned perfectly. 
This success story is a perfect example of how Firwin is able to combine outstanding and innovative technology with old fashion, high quality customer service.  If you want to learn more about our LFP™ Chemical Spray Shield visit our website, or contact us today!

Firwin Goes Way out West

Western Canada, which includes major population centers like Vancouver, Calgary, and Edmonton, has always played a big role in the global energy industry.  The region is one of the world’s largest exporters of energy resources and contains 13% of the world’s oil reserves, and 8% of the uranium reserves. However, in recent years, the rush to mine and drill almost every corner of the region has been off the charts.  There are even 12 working oil wells within Calgary’s (population 1,200,000) city limits!
At Firwin, we have been making a big effort to expand our business into western Canada.  Thanks to our amazing sales staff and quality insulation jackets, heat shields, and insulation covers, our expansion has been going very well.  In fact, we are in the middle of delivering a large order of insulation covers to a massive oil processing plant in the heart of Western Canada. The 3000 insulation covers are being used to cover some very sensitive and crucial industrial valves at the plant. Due to the region’s often extreme and unpredictable weather, keeping flanges, flow meters, and other instrumentation properly covered is of the utmost importance. Monitoring and maintaining correct line temperatures, raises the level of worker and equipment safety and productivity.  One of the best ways to accomplish this daunting task is by using proper insulation covers.
All Firwin insulation covers and blankets are manufactured in ISO 9001:2008 certified facilities and provide excellent heat retention and protection from environmental conditions such as heat, cold, and chemicals.

How to Install Firwin Removable Blankets

Finding the perfect insulation blanket is only half of the battle. If you choose the experts at Firwin to then you are off to a great start! However, without proper installation, even the highest quality insulation jackets, insulation covers, and heat shields won’t work properly and can give you a false sense of security.
To ensure your removable insulation functions properly and provides optimal heat reduction, you need to follow some important steps.
Before you begin installing our removable insulation blankets on your straight pipes, you first need a few tools:
•Stainless steel lacing wire
•Pliers and/or side cutters
As well, you need to know exactly where you are going install the blanket before starting. It may seem like a simple thing, but you need to be 100% sure about its placement before moving forward.
Once your tools and location are all set to go, it is time to install.
Step#1: Wrap the blanket around the pipe and form and compress the blanket while working close to the seam
Step#2 : Form a loop in the wire and hook it around the first rivet or hook
Step#3: Lace the wire across the blanket to close the seam.
Step#4: Lace entire length of the insulation blanket. After lacing the last rivet/hook, cut away lacing wire and wrap any of the excess wire around the last rivet.

On top of these four crucial steps, you must also remember that the outer material should never come in direct contact with any hot surface. As well, do not forget to inspect the blankets on a regular basis.
If you can follow these instructions, then you will be able to have confidence that your Firwin Removable Insulation Blankets will maintain peak performance. If you have any questions or need more details, please contact Firwin today.

Firwin and Chile

As we’ve discussed in previous blogs, open-pit mining is a great way to extract minerals and ore from the earth, but it becomes less effective when you start exhausting materials relatively close to the surface. It is at this crucial point that entire industries must make a choice: move on to another open-pit opportunity, or start the more difficult, time consuming, and expensive process of underground mining. This very dilemma is currently playing out in the Chilean copper mining industry. For years, copper mining has been the #1 industry in Chile. In 2000, Chile produced 35% of the world’s mined copper and it accounted for 40.5% of their export earnings, which translated into 25% of their GDP.[1] In 2006 alone, Chile exported $33.3 billion worth of copper. With copper being so critical to the health and survival of the Chilean economy, it is not surprising that their mining industry has begun a very ambitious underground mining project. The state-owned Corporacion del Cobre, the world’s largest copper producer, is planning to invest $3.28 billion in just one project to extend the working life of the world’s largest underground mine by 47 years. 
Because it’s hard to imagine any kind of mining without Firwin’s outstanding insulation and safety products, we recently acquired a new distributor in Chile. By signing up with the experts at Ventas,  Firwin hopes to gain a much larger foothold in the Chilean mining market. The timing couldn’t be better, and we hope that we will be able to help keep a future generation of Chilean miners safe and protected with our wide array of insulation products.


The Maid of the Mist and Firwin

At Firwin, we insulate a lot of serious equipment. Economies across the globe rely heavily on the mining, trucking, and marine industries. All of these endeavors can be dangerous without the quality insulation that Firwin provides. However, insulation isn’t all about hard work, it can also be about having fun. 
Since the first person set eyes on Niagara Falls, it has been a natural wonder that people have traveled far and wide to experience. By the mid 18th century, tourism had become Niagara Falls leading industry and that remains the case two and a half centuries later. Since 1846, the best way to see the falls has been from the deck of the Maid of the Mist tour boat. While it started out as a simple steamboat ferry, today there are actually four large diesel powered Maid of the Mists in service. Firwin is proud to have helped insulate these historic boats. Our marine and steam line insulation dramatically reduces heat loss from engine exhausts, piping, silencers, and piping. Because there isn’t much elbow room in the engine room of a smaller water craft, it’s even more important to shield the crew from excesses heat all while maximizing the effectiveness of exhaust catalytic purifiers and filters. That is why the Maid of the Mist fleet relies on Firwin insulation to guarantee that every trip past Niagara Falls is a safe and enjoyable one.

Firwin and Mine Safety

COPIAPO, Chile where 33 miners were trapped in a collapsed mine
From August to October of 2010, it was next to impossible to watch TV for more than 10 minutes without hearing about the 33 miners trapped in a collapsed gold mine 2,300 ft below Chile’s harsh and isolated Atacama Desert. The Copiapó mining accident captivated the world even after the miners safely returned to the surface.  It not only highlighted the strength of the human spirit, but it also shined yet another light on how dangerous mining can be. This near tragedy reminded us that even in the modern world, we cannot afford to ignore basic mine safety.  
In our last blog, we discussed the basics of open pit and underground mining. Today, we are going to highlight the challenges of both styles of mining and the substantial role that Firwin plays in keeping the mining industry safe. 
Open Pit Mining
Open pits, while being overall less demanding than underground mining, carry with them their own set of challenges. As with any activity involving large equipment like multi-ton trucks, loaders, and drills you need to use insulation blankets to shield personnel, cabling, and all heat sensitive controls from extreme temperatures.  However, open pit mining also introduces the problem of excessive sound and vibration.
Many open pit mines across the world are located near population centers, especially in countries like Australia. Therefore, companies have to find a way to effectively mine, without disturbing nearby residents and businesses.  Firwin has insulation blankets that combine both temperature and noise/vibration protection, thus allowing open pit mines to run 24-7 safely and without causing local resentment and structural damage. 
Underground Mining
As the world has turned more and more to underground mining, Firwin has started to focus on developing a special line of insulation products aimed at the unique challenges of underground mining. Digging any tunnel, shaft, or adit is difficult, time consuming, expensive, and inherently dangerous. After a good deal of research and testing, Firwin created our proprietary MineWrap™ Removable Insulation Blankets expressly for underground mining.
MineWrap™ Removable Insulation Blankets
Our MineWrap™ addresses some of the less obvious areas of concern of underground mining. It protects again the dangers of hydraulic oils spills on hot engine surfaces, reduces operator burns, limits oil seepage, and can withstand extreme wear and tear. Though not as well documented as cave-ins like Copiapó, these problems can lead to equally as devastating occurrences. 
Whichever mining technique our customers utilize, they know that Firwin has the products, experience, and expertise to make the mining process safer, cleaner, and more productive. Furthermore, all of our mining insulation is custom made to fit your specific equipment and our blankets conform to UL2000 standards.

Underground versus Open Pit Mining

If you scan any news source these days, you will find countless stories about the world’s unquenchable desire for mineable resources like oil, coal, and precious metals. Recently, Firwin has begun to extend its reach into the ever-growing world of mining. With this in mind, we thought this would be the perfect time to review the basics of this most crucial of industries. 
A little background
Over the past century, the mining world has taken full advantage of amazing technological advances and innovation. Today, instead of using candles and canaries, miners use LED integrated explosion-proof cordless mining headlamps and multi-purpose gas detection sensors. However much technology mining now incorporates, the basic idea behind the act of mining remains the same: something you need is in the ground and you have to find a way to get it out. As one might expect, there is a wide variety of mining methods available today; yet when it comes down to it, all of them can be split into two basic categories: underground mining and open pit mining.
Open Pit Mining
As its name indicates, open pit mining is a method of extracting rock or minerals from open pits, like quarries and burrows. This ancient form of mining requires no tunneling and is utilized when substances are fairly close to the surface. These mines are not just big open holes. Instead, they consist of a series of ledges or benches, which companies dig at angles to allow for extraction without causing structural weaknesses. There are open pit mines all over the world and they yield everything from clay and coal to uranium and gold.
Underground Mining
If an area’s open pit mines are exhausted or impossible to build due to the inaccessibility of the desired resources, the mining process goes underground. There are several different ways to mine underground. You can build spiral tunnels that circle the deposit, sink vertical shafts adjacent to the ore, or create adits, which are horizontal excavations into the side of a hill or mountain.  Unlike open pit, underground mining requires that you take into account a wide variety of added requirements. These include complex ventilation systems, area and local ground support, and of course finding a consistent, safe, and cost-effective way to get your materials to the surface.  Just for reference, the deepest mine in the world is South Africa’s TauTona gold mine, which is over 12,800ft or almost two and a half miles deep. 
Whichever mining technique you choose (or are forced to choose), there are a number of unique challenges that can’t be ignored. In our next blog, we will discuss the role that the insulation experts at Firwin play in making today’s mines safer and more effective.

Are Insulation Blankets Safe for Outdoor Applications?

There are two possible problems when considering using removable insulation blankets for outdoor applications:

•    The potential for water to get underneath the blanket and stay, which could in turn lead to pipe corrosion under certain circumstances.
•    The possibility of poor insulation performance when exposed to the elements.

Because insulation blankets, by nature, are not sealed, they are not impervious to water. Brett Herman, Firwin’s VP of sales and customer services, says the first question you should ask yourself when considering using insulation for an outdoor application is, “Can I afford any water getting under the blanket?” If the answer is no, then insulation blankets are not likely candidates for you application. However, if the problem isn’t a question of water getting under the blanket, but rather a fear of the water lingering, removable insulation remains a viable solution.

In many applications, high temperatures from typical engine exhaust cylinders (provided they are non-cyclical) will burn off excess water that remains under an insulation blanket—thus eliminating the risk of corrosion. In terms of ability to perform in outdoor conditions, insulation blankets’ standard outer layer (silicone impregnated fiberglass) can withstand temperatures as low was -67° F before cracking—and some even feature a UV resistant coating. When it comes to responding to water, some kinds of insulation are more water-resistant than others.

To accommodate outdoor applications, Firwin incorporates design modifications into blankets, such as extra flaps to reduce the amount of water that gets beneath a blanket. If corrosion is an issue, Firwin may also recommend consulting with an outside corrosion engineer.

Appropriate Insulation for Marine Applications

Marine applications differ from land-based applications in three main areas: Firstly, a ship engine is typically used for prime power, so it is running all the time and generating a lot of continuous heat, unlike a back-up power generator. Secondly, and perhaps even more importantly, are the additional safety concerns that arise from being a sea-borne vessel—out on the water is not a place for heat-related issues. Thirdly, the engine room is often in tight quarters, increasing the likelihood that someone brushes up against a hot exhaust component.
For these reasons, Firwin typically recommends a thicker level of insulation than would suffice in standard non-marine power applications – usually 2-inch thick insulation blankets, as long as space allows. Extra care is also taken in designing the blankets to ensure that small gaps between components are covered. Firwin Hard Coat is also an excellent alternative to removable insulation blankets for marine applications, especially in cases where space constraints do not allow for thicker insulation.

Alternative Fastening Techniques for Insulation Blankets

Over the years, Firwin has developed more than a few ways of building fasteners for its removable insulation blankets, but its traditional modus operandi has always been with stainless steel lacing wire. “We find that stainless steel lacing wire works best,” says Paul Herman, Firwin’s president. “But for certain applications, where speedy installation is key, or where the client will be removing the [insulation] blankets frequently to do maintenance, we will recommend alternatives.”
So what are some of the alternatives? Thus far, Firwin has developed and produced insulation blankets that can be fastened by way of straps, snaps, springs, even Velcro. All of these options provide lighter, cheaper, and more accessible means of opening and closing insulation blankets.
 A recent challenge: Firwin was tasked to develop a new spring system for one of its clients. But first there were a few slight problems that required solving. As Brett Herman, Firwin’s V.P. of Sales & Customer Service, sums it up, “We have made spring fasteners available to our customers in the past… However, we used to find that the spring fasteners available ‘off the shelf’ just did not provide the proper fit that insulation blankets require. We knew that if we were to provide spring fasteners as a legitimate option, we would have to design one ourselves.” 
That’s just what Firwin did. Working with a local spring manufacturer, Firwin retrofitted their fasteners so that they would snap off with ease, all the while maintaining their sturdiness over time and at high temperatures. Insulation blankets fitted with these new and customized spring fasteners (as well as all other fastening alternatives) are currently available from Firwin upon request.
