Glue for polypropylene pipes

1- The first layer of polyethylene resin (usually yellow, green, orange, blue)

2-Glue between layers of Carogate

3-Middle layer of ST12 steel or Z20 galvanized sheet

4-Glue between layers of carogate surface

5- Outer layer of black polyethylene

This generation of pipes have high resistance and mechanical properties due to exposure to pressure and temperature

Due to the non-polarity of the raw polymer and the polarity of the metal layers, the interlayer adhesives help the adhesion to reach the desired standard.

Three-layer polyethylene coating of steel pipes:

One of the main complications in oil and gas pipes is the issue of metal corrosion, steel pipes in this industry are protected by three-layer polyethylene (HDPE) coatings that adhere to the surface of the pipe through an epoxy intermediate layer, but over the years In the past, according to the many reports both inside and outside the country about the corrosion of pipes due to the separation of this protective layer from the surface of the pipe, it led to the design and production of an inter-layer adhesive to create long-term adhesion and resistant to temperature stress. expansion and contraction). By creating polar compatibility between the epoxy layer and the external polyethylene layer and greater adhesion, all the stresses created from the surface of the metal pipe will be transferred to the protective layer of polyethylene and will prevent pipe decay and corrosion.
