Heat Shrinkable Sleeve for 3 Layer PE Coating Pipe provide mechanical protection to the epoxy layer and
seal onto the epoxy layer and the adjacent line coating.
The first layer of the joint coating system is a 100 % solids two component
epoxy of a minimum dry-film thickness of 150 microns when applied on the steel surface. The epoxy layer is the primary anti-corrosion barrier and
capable of corrosion protecting the steel surface on a standalone basis
Backing: > 1.0 mm
Adhesive: > 1.0 mm
Total sleeve (Backing + Adhesive): > 2.0 mm
To prevent damage to the adjacent 3LPE line coating, the pre-heat of the weld area prior to epoxy application shall not exceed 80℃. After application of epoxy to joint area, the shrink sleeve shall be shrunk over the epoxied surface while the epoxy is still in a gel state and shall not require post curing of the epoxy layer prior to sleeve shrinking. This is to prevent contamination of the epoxy surface caused by direct flame.
Sichuan Forever main products has heat Shrinkable Sleeves, Pipe Repair Material,Liquid Epoxy Coatings,Visco-Elastic Coating Materials,Cold-Applied Polymeric Tape and other Wrapping materials application tooling.
How to choose the width of HSS ?
The sleeves on the weld joint shall be wide enough so as to overlap onto the
mainline coating by a minimum of 50 mm on each side of the weld joint once
installed. The installed sleeve width shall be considered as the edge-to-edge width of the backing of the sleeve once fully shrunk down.
The sleeves on field bends may be wider and shall overlap onto each other by a minimum of 50 mm once installed.
