Hot Melt Tape Pe Pipe Heat Shrinkable Sleeve
It is a kind of connecting pipe fitting what is widely used on anti-corrosion, especially on Directly buried pre-insulated pipes field joint. It is made by Polyethylene sheets complex with the electro-fusion wire.
1. According to the pipe corrugated process, the peak valley width usually from 60mm to 80mm, the Narrow tape welding the pipe joint along the cutting edges.
2. Because of various of restrictions, can not guarantee the airproof capability after the pipe joint welded.
3. The best way to weld the joint should use the Hand extruder welding the cutting edges inside of the pipe first, the use the narrow tape welding it from outside.
Hot Melt Tape Pe Pipe Heat Shrinkable Sleeve (3 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.
Fast shrinkage speed, good waterproof performance, good anti-corrosive performance, long service life, convenient transportation and fast construction. The product are ideal material for corrosion prevention and insulation.
It's mainly used for heat pipe network, steel pipe corrosion resistance and insulation, chemical pipes and sewage pipes etc.
Heat Shrinking Wrap
Selecting the proper sleeve:
Project specifications and local standards must be considered when specifying a shrinkable sleeve.
Next to these the following parameters must be considered for selecting the proper shrinkable sleeve:
Pipe Coating Type:
F. I. Bitumen, Coal Tar Enamel (CTE), Cold Applied Tapes (CAT), Fusion Bonded Epoxy (FBE), PolyEthylene (PE), PolyPropylene (PP), ...
Pipe Operating Temperature:
0 - 120° C (0-248° F)
Pipe Operating Pressure:
F. I. 100 mbar = 1, 42 psi, >4 bar = 56.88 psi, ...
F. I. Gas, water, oil, ...
F. I. 1" or DN25 for steel pipe, 160 mm jacket diameter for insulated steel pipe, ...
Surface cleaning: F. I. Abrading, brushing, gritblasting obtainable preheat temperature: Low (60-70° C) (140-158° F), high (80-100° C)(176-212° F), very high (230° C) (446° F)
Adverse Soil Conditions:
Stable: Low soil stresses unstable: Shifting soil conditions, significant pipe motion relative to soil
Mechanical Resistance Heatshrinkable Coating:
Medium (B): Moderate impact and penetration resistance high (C): High impact and penetration resistance
Pipe Laying Method:
F. I...Open Trench, Directional Drilling, Off-Shore Climate conditions (Ambient Temperature during Sleeve Application):
Sea climate: Not very cold - not very warm
Land climate: Very cold - warm
Desert climate: Very cold - hot
All of the above parameters affect the type of coating which will provide the best performance, ease of installation and value. The following selection tables will help you to decide which sleeve is right for your application
