3PE/2PE Corrosion-Resistant Steel Pipe (Standard/Enhanced Grade)

3PE corrosion protection typically consists of a 3-layer structure:

One coat of epoxy powder (FBE > 100um)

Double-sided Adhesive (AD) 170-250μm

Three-layer polyethylene (PE) 2.5-3.7mm

In practice, the three materials are blended together and integrated, then processed to form a firm bond with steel pipes, creating an excellent anticorrosive coating. The processing methods typically include winding and round mold wrapping.

Advantages of 3PE Corrosion-Resistant Steel Pipe

1. The 3PE anti-corrosion steel pipe has excellent sealing properties, which can significantly save energy, reduce costs, and protect the environment during long-term operation.

2. Excellent corrosion resistance, quick installation, and a service life of up to 30-50 years.

3. Excellent corrosion and impact resistance at low temperatures, with a low water absorption rate for PE.

4. Offering high epoxy strength, low PE water absorption, and excellent softness of hot melt adhesive, this product boasts high anti-corrosion reliability. Its anti-corrosion features include simple manufacturing process, effective protection, and low cost, making it a universally recognized anti-corrosion method in the pipeline industry. This method is commonly used for the anti-corrosion of three-layer polyethylene (3PE) steel pipes for oil and gas applications, as well as two-layer polyethylene (2PE) steel pipes. Standard: SY/T0413-2002; DIN 30670
