Product Details

3LPE coating pipe production line Joint PE Heat Shrinkable Sleeve,solid and durable
 
 

It is mainly composed of base material and hot melt adhesive. Our company adopts unique hot melt adhesive formula to ensure the adhesive strength of the product in use and thus ensure the construction quality. Optimization of the design of the new heat shrinkable tape (set) is easy to site construction, fast shrinkage, short operating time, low construction costs, with excellent water vapor permeability, chemical corrosion resistance, insulation and aging resistance and other properties, is the ideal material for pipeline anticorrosion thermal insulation system. Among them, three layers of reinforced fiber type heat shrinkable tape (set) is in a layer of substrate, a layer of adhesive coating between a layer of reinforced fibers, adhesive strength and higher tensile strength, contraction faster, the effect is also better. Mainly used for oil and gas pipeline joints to fill the mouth of the anticorrosion, patching, can also be used for pipeline damage repair. This product is suitable for 3PE steel pipe, 2PE steel pipe, epoxy powder coating, thermal insulation pipe jacket skin and polyethylene drainage and sewage pipeline pipeline patching, patching.

Some customers in order to shorten the time, the use of fire in the construction, in a short time to melt the heat shrink strip base material, but not preheat the base material, and a 300mm pipe baked in 2 minutes, look at the appearance is contracted up, the actual internal glue layer just melted, did not reach the two sides of the rubber, the end of the bake, the product did not play its due role, Put a period of time will appear curly edge and other conditions.

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.

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.
