HWS Anti-corrosion Pipeline Heat Shrink Sleeve
HWS Anti-corrosion Pipeline Heat Shrink Sleeve is also known as heat shrink weld belt/Heat shrinkable weld sleeve (belt), made by irradiation cross-linked polyolefin base material and special sealing hot melt adhesive. WHR Three Layers Heat Shrink Sleeve For Anti-corrosion it has high mechanical strength, stable performance, aging resistance, anti chemical corrosion, sealing, strong adhesive strength, easy to operate, etc.
a) Pipeline Engineering Tubing Apply to petroleum, nature gas, chemical engineering, fuel gas and others project pipeline network for anti-corrosion of steel pipeline repaired and welded junction.And also apply to corrosion resistant coating for repairing the breakage.
b) Apply to 2PE, 3PE, FBE,PP,CTE anti-corrosion coating pipeline for anti-corrosion of welded junction and bend area.
When using the heat shrink sleeves, first preheat the pipeline up to 55 degrees Celsius~60 degrees Celsius, and then wrap the joint belt around the treated pipeline with the heat shrink joint belt, make sure that the heat shrink joint belt lap width is more than 50mm, it will shrink at radial direction when the heat effects on it, at the same time the hot melt adhesive start to melt, fill and cover the surface of the pipeline, form continuous and close anti-corrosion system with original pipeline anti-corrosion coating.
Executive Standard: SY/T0413-2002 and SY/T4054-2003 and GB-T23257-2009.
Features & Benefits
a) excellent adhesion ability, adhesion range is wide: can adhere with steel, PE, epoxy coating, etc.
b) strong in corrosion resistance:can effectively block a variety of medium permeability and corrosion, aging resistance, environment stress cracking resistance, resistance to UV irradiation.
c) High mechanical strength: compression resistance, shock resistance, shear resistance.
d) Wide use range: can instruct at -25~35 degrees Celsius temperature range.
e) No volatilization, safety in use, can save energy, can protect environment
f) Long service life.
g) Shrink fast, easy to operate, simple to install.
h) low preheat temperature: when preheat -55~60 degrees Celsius, can install it to shrink.
Other size can customized according to customers' request.
