ERS WRAP™ VALVE AND FLANGE COVERS
ERS Wrap™ Blanket Industrial Insulation is a Multipurpose, Removable and Reusable Industrial Blanket Insulation Made of Fiberglass Insulated Fabric For Use in Mechanical Industrial Insulation For Insulating High Temperature Processes.
ABOUT ERS WRAP™ VALVE & FLANGE BLANKET INSUALTION
ABOUT: ERS Wrap™ is a multipurpose sewn industrial insulation blanket that can be used to insulate virtually any hot mechanical part up to approximately 400°. Our industrial insulation blankets will significantly reduce surface temperatures, providing personnel protection and saving you money!
APPLICATIONS: We primarily use our small blanket ERS Wrap™ covers to insulate valves and flanges. They come in various widths and lengths, but are all rectangular in shape. They also come in handy when insulating irregular components!
MATERIAL SPECIFICATIONS: The small insulation blanket covers are made using a silicone impregnated fiberglass fabric, and lined with temp mat. Temp mat is a fiberglass needled insulating fabric suitable for high temperatures. Click the below button to learn more about the materials used to fabricate ERS Wrap™.

FLANGE OD = ADJOINGING INSULATION OD: We've installed thousands of flange coverings. If the adjoining insulation is the same outside diameter (OD) as the flange, 6" width is a good fit.
FLANGE LARGER OD THEN ADJOINGING INSULATION: If the adjoining insulation is a of a smaller outside diameter (OD), you may want to do go wider and use the "build-up" method for the exposed side facing flange. See our video below demonstrating the build up method.
VALVE: A 12" or 16" width works for most valves. The width of the valve cover is determined by measuring from outside flange, to outside flange.
With all of our products, when in doubt, GO LARGE!!
DETERMINING WIDTH OF VALVE OR FLANGE COVER
To determine the appropriate length, we calculate the circumference of the flange. We calculated circumference based on iron pipe size (IPS) of the adjoining pipe for class 150 flanges. You need enough length to "wrap" the cover around the flange and have it overlap.
DETERMINING LENGTH OF VALVE OR FLANGE COVER
INSTALLING ERS WRAP™ VALVE & FLANGE BLANKET INSULATION
TOOLS/SUPPLIES NEEDED: Cable ties, cable tensioners, scissors, staple gun/staples, and silicone caulk
1. ADJOINGING INSULATION LEVEL WITH FLANGE: Wrap cover around the flange. Make sure to do in a watershed position. Secure with outdoor grade black or stainless steel cable ties. DONE.
2. ADJOINING INSULATION IS LEAVES SIDE FLANGE EXPOSED: Check out the below video that demonstrates the "build-up" method.
3. VALVE - NO CUT FOR LEVER: Based on the size of the bonnet, we will recommend a cover or a roll appropriate. The blanket insulation is wrapped around the bonnet or middle component of the valve. If the lever is on the top of the bonnet, no problem. Wrap and secure using cable ties.
4. VALVE - CUT NEEDED FOR LEVER: If there is a lever on the body of the bonnet, you will need to cut the cover to accommodate the lever. Where the insulation is cut, you can fold the cut portion under and staple the insulation. Additionally, you can apply silicone caulk to enhance the appearance and prevent the inflow of water. Secure the cover with cable ties.
Flange and Valve FAQ
How long does it take to install?
You can install ERS Wrap to a valve or flange in minutes!
What tools/supplies do I need to install ERS Wrap on a valve or flange?
1. Cable Ties - You can choose outdoor grarde black cable ties or stainless steel
Do I need a professional to install?
No! Anyone who can operate cable ties and scissors is qualified to install our ERS Wrap blanket insulation.
Why are valves and flanges left uninsulated?
A flange and valve are larger in diameter then the ajoining pipe so they are often left uninsulated.
What if I have an outside face exposed?
No problem. You can also check out our video on the "build up" method.
Will I need to make any cuts?
For a flange, no.
Do you sell all the tools and supplies needed for install?
What is the outside diameter for class 150 flanges?
Like most things in the industrial insulation world, we start with the iron pipe size (IPS). We calculated the circumference for our flange recommendations based on class 150 flanges.
Column 2: Outside Diameter for Class 150 Flange
Column 3: Calculates circumference needed using 1/2" temp mat
Circumference = (flange OD + 1" total width of tempmat) x pi or 3.14 rounded to the nearest whole number
Column 4: Rounds the 3" to ensure the cover has enough length to overlap
What does the class of a flange mean?
The class of a flange refers to the maximum pressure that a flange withstands at increasing temperatures. Flanges with a higher rating (class) are stronger than flanges with lower ratings, as they bear more pressure at increasing temperatures.
How many flange classes are there?
There are seven flange classes: 150#, 300#, 400#, 600#, 900#, 1500#, and 2500#.
How do you calculate the circumference of a flange?
You must first determine the flange OD or outside diameter. You must also add the width of the insulation x 2 and then muliply by pi, see below:
