Blanket Installation Tips

Blanket Installation Tips

Insulation blankets help protect personnel by containing potentially dangerous temperatures inside the affected component so that the ambient environment remains stable and safe.  Insulation blankets can also control temperatures during mechanical operations to keep temperature fluctuations from damaging the surrounding equipment. Although most insulation blankets are designed to prevent heat from transferring outside of a hot component, they can also be used to insulate cold areas or keep them from freezing.

Firwin’s insulation blankets are removable so workers can access the equipment beneath them for maintenance and repairs. But it’s critical to properly reinstall the blanket after servicing to ensure there aren’t any gaps in coverage. Even minor rifts can leak heat into the surrounding area, potentially decreasing the overall operational efficiency and creating a hazard to nearby workers.

As a premier provider of industrial insulation solutions for customers in a range of industries and applications, Firwin has the knowledge and expertise to insulate your equipment and make your workplace safer. In the passage below, our seasoned experts share tips on how to ensure your removable insulation blanket is installed correctly.

Get the Right Tools

To install an insulation blanket, you’ll need the following tools:

Safety Gear

If the equipment is hot or continuously operating, workers must have the appropriate personal protective equipment (PPE) to defend against surface heat, ambient heat, steam, liquids, chemicals, and any other unsafe conditions that may arise. The installer should wear protective gloves while handling the cable lacing.

Stainless Steel Lacing Wire

Firwin’s removable industrial blankets typically use stainless steel lacing wire to wrap the blankets around the equipment and fasten the edges to the rivets on the blanket. The wire offers a reliable and durable bond that is temperature-resistant and long-lasting, even in extreme conditions. Other fastening methods are also available.

Pliers or Side Cutters

The installation technician will likely use a set of pliers or side cutters to twist and manipulate the lacing wire and fasten the blanket to the equipment. They may need to cut the wire to size once it has been laced.

Installation Guide

Before you begin your installation, double-check that your equipment matches with the corresponding label on your blanket. Firwin’s insulation blankets come in a broad range of sizes, configurations, and designs that are specially engineered to provide optimal coverage for corresponding pieces of standard equipment. Placing the wrong blanket on a component will not offer the coverage you need and could result in unsafe gaps or overlap that reduces the efficacy of your insulation.

Have a Plan or Template

Blanket installation processes vary depending on the equipment configuration and facility. Before you begin, decide where each blanket will go and the order in which you plan to install them. Some blankets are designed to go above or below others, so you need to put a detailed installation plan in place to avoid errors or unnecessary delays.

If your system includes unions or elbows, note that both union and elbow blankets should be installed after the standard pipe insulation blankets have already been fastened.

Ensure Full Coverage

Here are some additional tips to ensure your insulation blankets are installed with optimal coverage:

Overlap Edges

Blanket flaps should overlay at the seams without creating any gaps or spaces. Even small gaps can allow heat transfer, thereby reducing the efficiency of your system.

Crisscross Wiring

Lace the wire around each rivet across the blanket’s seam in a crisscross pattern. Then trim and bend the excess wire to ensure that it stays in place and won’t catch on other pieces of fabric or equipment. Make sure to secure the wire on the union and elbow blankets to the rivets of the primary insulation blanket for optimal coverage and stability.

Increasing Engine Efficiency with Insulation Blankets

Many of today’s modern engines have two chargers that help to improve engine efficiency, and for which insulation blankets have an important role to play—turbochargers and charge-air coolers.

To understand how insulation can help you get the best performance from your engine, you first need to know how turbochargers work. The function of a turbocharger is to increase the mass of air that enters the engine, which leads to a greater air/fuel mix and boosts the horsepower. This is achieved by an internal turbine and corresponding compressor. The turbine, which can spin at speeds over 200,000 rpm, drives a compressor, which increases the amount of air entering an engine’s cylinders. Because the turbocharger’s turbine is powered by the engine’s own exhaust and because of the rapid rpms, turbochargers run at extremely hot temperatures.

The extreme heat generated by turbochargers can stress sensitive engine parts in the piston and cylinder area, and have a detrimental effect on surrounding engine components and employee safety.

Unlike turbochargers, charge air coolers run cold. Charge air coolers work to cool the compressed air that leaves the compressor before the air enters the engine. The increased density of the colder air means that more air can fit into the engine, for greater power. Charge air coolers thus improve the efficiency of the turbocharger and engine by allowing a greater mass of air to enter the engine at one time.

Insulation blankets are used in conjunction with both turbochargers and charge air coolers. For turbochargers, the blankets keep the heat from escaping the turbochargers and from entering the surrounding engine components. For charge air coolers, insulation blankets are found on the hot piping that leads from the turbocharger to the cooler, in order to protect personnel who might be in the area.

What to do about a square peg in a round hole?

Odd shapes and sizes are always something that design engineers encounter when creating everything from pipe fittings to fasteners. With insulation blankets, varying geometries and protrusions from engine and exhaust components and process piping are regularly encountered in the design phase.  At this point, when the surface to be covered isn’t smooth, how does that blanket fit?

Here is where our custom blanket services fit in. When it comes to the design portion of the production phase, our design engineers evaluate the surface and piping, and can create a blanket to accommodate any protrusions or cut outs.

How do we go about this with our customers? There are a few different options of reviewing and obtaining this kind of information. First and foremost, if the insulation blanket is needed in an emergency situation, with no lead time to make a custom cover, we can send a blanket and the customers can make the cut outs themselves according to the placement of the brackets. If that is not the situation, then our design engineers look at the end application. If the jacket will be covering a silencer, then they will supply the customer with a support brackets drawing they can fill out. If it’s a different component—such as for the oil and gas industry—we will then ask for CAD drawings or specific dimensions from the customer. Despite the application, it’s always pertinent for our design engineers to have drawings of the equipment that will be blanketed.

The most important aspect of the blanket design is that, according to our article, our “design team ensures that any cut-outs or openings are designed in such a way as to allow sufficient room for the protruding item, while minimizing any heat loss due to the lack of insulation.”

Whether you’re worried about complex geometries or protruding components on your equipment, don’t fear—our design engineers can create an insulation blanket for every application.

Tips on Caring for your Removable Insulation Blankets

At Firwin, we take pride in the performance and longevity of our removable insulation blankets.  We manufacture all of our products to withstand the toughest and most challenging environments, be it hundreds of feet underground or on the roughest seas. In order to make sure our insulation jackets maintain peak performance, it helps to follow a few easy care tips.

1. Firwin’s fastening systems are extremely strong, but it is important to avoid excess force when installing your insulation blankets.
2. It isn’t always easy, but for the best service, keep your blankets as clean as possible.
3. Promptly remove or clean off all chemicals that cause deterioration of aluminum or silicone coatings.
4. Avoid oil saturation; this will render your blanket’s “non-combustible” characteristics ineffective. You will then need to replace the covers.
5. Treat blankets like all parts of the engine and inspect them regularly.
6. Last but not least, always take care not to cut or damage the outer protective cover fabrics. It helps to limit the usage of sharp instruments around all insulation blankets.

If you follow all of these steps, you can automatically increase the lifespan of your removable insulation blankets. If you have more blanket care questions, please contact one of our insulation blanket experts today!
