Caseal and Flange Protection Kit Shrink Ratios

 How much does Caseal and Flangseal Material Shrink?

     Both Caseals and Flangeseals are made using a Covalence reinforced, high expansion, mastic sealant coated heat shrink sleeve.  The material essentially has two layers of a modified polyolefin backing, with a PP fiber mesh woven between them.  This gives the sleeves excellent penetration resistance, abrasion resistance and gouge resistance.  In addition - this allows the patented process to make a shrink sleeve that shrinks as much as 66%.

     Held together by sewing a nylon zipper onto the sleeve (using heat resistance kevlar thread), the sleeve stays in the shape of a tube through the entire shrink process.  The zipper is protected from the torch by a closure strip.  

     Looking at just a few of the Caseal sizes; a Caseal is able to wrap around a 48" OD Casing pipe and shrink down and seal to an 18" carrier pipe (if allowed) though the CS 48000 is primarily designed to seal to a 30" carrier.  There just aren't a lot of scenarios where someone would pay for a 48" casing pipe and put an 18" carrier running through it.  Waste of money!

    Likewise a Flangeseal is able to shrink in a similar manner.  As one example, an FS 48000 is designed to wrap around a flange with an actual OD of 48".  That Flangeseal could then shrink down to a 17" Pipe (again - this would likely never happen).

    In either case, both Caseal and Flangeseal are capable of covering a multitude of different Casing / Carrier / Flange / Pipe dimensions - and we almost certainly have a product that can help with your project.

The Best and Simplest Way to Seal a Buried Flange

 How to Prevent Corrosion on a Buried Flange

An installed Covalence Flangeseal

     So, you need to protect your flange (that is going to be buried eventually) from corrosion.  The Covalence (formerly Raychem) FlangeSeal is an excellent option for you.

    Flange Seal offers a high expansion, fiber reinforced backing and an extremely aggressive mastic sealant.  Shipped out with a strip of cardboard - which is wrapped around the Flange first - means that Flange doesn't get too messy and can be re-enterable one day if you need it.  Installed using a propane torch, it just doesn't get any easier than an FS Flangeseal installation.

     But there are three very important bits of information that you need before you can quote or order a Flangeseal.  

FIRST:  You must know the actual outside diameter of the flange you'll be installing on.  There are a number of flange manufacturers out there and many different types of flanges.  Simply knowing "300# 12 inch" just isn't enough to avoid a possible problem.  The Flangeseal must be large enough to wrap around that flange -- so prepare yourself -- you will be asked:  "What is the outside diameter of the FLANGE?".

SECOND:   You need to know the OD of the pipeline!  We need to be certain that the Raychem Flangeseal is able to shrink enough to properly wrap around the flange -- and shrink all the way down and seal to the pipeline.  

THIRD:  We will need to know if your specific parameters can be met with a 24" wide Flangeseal (FS) or if you need to look at using a 36" FS?  

     With those three bits  of information:

1. Actual Outside Diameter of the Flange
2. Outside diameter of the pipe
3. Width of the FS required

You'll have that Flange protected in no time!
