Hot Melt Tape PE Pipe Heat Shrinkable Sleeve

1. HSSC-1 Heat shrinkable sleeve (2 layers), which are developed and manufacture by Qingdao Huashida machinery Co., Ltd for anti-corrosion of pipeline, are the composition of radiation cross-linked polyethylene backing and high shearing strengthen melt adhesive, and have the function of shape memory. The hot melt adhesive is squeezed into the joint by the shrink power to form a perfectly sealed surface, after being heated. HSSC-1 is compatible with standard pipe coating, also can be used for coating bare, replacement pipe section and large radius bends. The system is designed to be applied with minimum preheating and is ideal for large diameter wastewater pipe

Application scope
The heat shrinkable sleeve is designed to be applied with minimum preheating and is ideal for large diameter wastewater pipe. 3PE pipe and pre-insulated pipeline joint closure.

Feature
1.Fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life, convenient transportation and fast construction.

2. 3Layer Fiber

reinforced PE heat shrinkable tape (sleeve) is composed of cross-linked polyethylene back, a middle layer of fiber and special heat melt adhesive an. The 3 layer reinforced sleeve gives better shrink ratio, and better strength. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.
Application area:
It is mainly used for Hollow wall spiral pipe, corrugated pipe and metal reinforced corrugated spiral pipe etc.

TEST PROCEDURE
1. Clean the steel pipe and heat it by fire till over 80 ºC
2. Paint the steel pipe with Primer (mixed with A&B)
3. Fire heat the heat shrink sleeve, be attention to start heating from middle of the sleeve, but act from up and down, and gradually move from middle to two sides of sleeve, in order to drive air out of the sleeve, after finish heating, the good result is that there is about 1-2mm hot adhesive melt at the edge of sleeve.

Heat shrinkable Sleeve construction

The first is - high mechanical strength, strong anti-aging ability;
Second, good resistance to environmental stress;
Third, excellent bonding performance;
The fourth is - easy to use;
The fifth is the implementation of standards SY/T 23257-2017, NACE RP0303-2003;
Sixth, the application of external anti-corrosion coating :PE, FBE, PP, recommended rust removal grade :Sa 2.5;
The seventh is more prominent - the product specifications can be used for all steel pipes DN100-DN3000;
The eighth is that the thickness of the substrate is from 1.0-2.0mm, and the thickness of the rubber layer is from 0.2-2.5 for various construction models can be selected.

Construction precautions

Repair construction can be manual or mechanical installation. A non-polluting heating method should be used to heat the patching part of the steel pipe surface, and a mechanical heating method should be used for large diameter pipes. Heating should not cause surface pollution of the steel pipe, should not damage the anti-corrosion layer of the pipe body
The welding joint should be cleaned, and the burrs, welding slag, spatter and welding burrs in the circumferential weld and its vicinity should be cleaned. The dirt, oil and impurities at the patch should be cleaned up; When the end of the anti-corrosion layer has warping, rust, cracking and other defects, it should be cleaned
