PE Heat Shrinkable Sleeve Wholesale Pipe Joint Materials

Product Description

Wholesale pipe joint materials
Heat Shrinkable Sleeve Insulation Connector
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
Feature
1.Fast shrinkage speed,
2.good waterproof performance,
3 good anti-corrosive performance,
4.long service life, convenient transportation and fast construction.
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.

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.
TEST RESULT
1. Test result after cooling about 40 minutes.
Peel strength to primer is over 100N per 2cm(till the end of the spring balance). at 30.7ºC
Co-adhesive: Half-half.
2. Test result after cooling about 24hours.
Peel strength to primer is over 172N per 2cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
3. 2. Test result after cooling about 24hours.
Peel strength to primer is over 9.2kg/90N per 1cm at room temperature about 30.7ºC
Co-adhesive: Half-half.
