Polypropylene winding with anti-corrosion pipe fittings

Polypropylene cold bound with the polypropylene fiber pipeline anticorrosion with cold wind belt can be widely used in petroleum, natural gas, chemical industry, water supply and drainage in the urban construction, oil and gas, gas transportation steel pipe and steel buried storage tanks outside antisepsis and repair projects. It is made of a unique polypropylene reinforced fiber for backwood and a certain thickness of high viscosity butyl rubber modified bituminous anti-corrosion rubber.

Advantages of polypropylene cold bandage:

1. Convenient site construction and flexible construction;

2. Impact resistance, tensile strength, high bond strength;

3. Anti-aging and uv resistance;

4. Non-toxic and harmless to human body.

Specification for polypropylene cold wrap:

Product width - base film thickness/layer thickness

Product width (50, 75, 100, 150, 200, 250, 300 mm)

Base film thickness (0.20mm-0.80mm)

Thickness of rubber layer (0.10mm - 0.30mm)

Application of polypropylene cold band:

Surface treatment: rust removal, removal of slag, burr, oil dirt, manual derusting of St3 grade, sandblasting and Sa2 grade;

Painting primer: A and B are evenly stirred and coated with brush or roller.

Lap winding: after the primer is dry (usually 5-10min), it can be coiled.

Transportation storage of polypropylene cold wrap:

Polypropylene cold wind belt should be in a cool, 5 ℃ - 30 ℃ under the environment of storage, away from heat and open flame;

The polypropylene cold belt is exposed to the sun during transportation.

Polypropylene cold wind belt is 5 ℃ below critical frozen for a long time, need to be around 20 ℃ for 48 hours later, just can use.
