The main features of TPEP anti-corrosion
steel pipe are:
1. The anti-corrosion performance of polyethylene can withstand various corrosions existing in the natural environment;
2. Has a high quality-price ratio;
3. Polyethylene has excellent insulation performance, and the electrical performance is unchanged under dry conditions and long-term water immersion conditions, which can effectively prevent electrochemical corrosion caused by stray currents;
4. It has strong resistance to microbial corrosion and deep-rooted plant root thorns, and will not cause plant root penetration;
5. High strength, can be directly backfilled with soil containing non-artificially crushed gravel with a diameter ≤Φ25mm without causing any damage;
6. The overall bending resistance of the coated pipe is strong, generally speaking, cold bending is allowed to be 1.5°/pipe diameter;
7. Strong resistance to cathodic dis-bonding, which is very important for cathodic protected pipelines;
8. The production process is all continuous mechanization, and the product quality is stable, which is conducive to comprehensive quality control;
9. All raw materials for polyethylene-coated steel pipes are produced by large enterprises, with reliable sources and guaranteed quality;
10. Long service life, theoretically can be used for more than 50 years.
