Non-toxic and anticorrosive steel pipes for underground pipeline are essential facilities in ground engineering, serving as carriers for oil and gas transmission. They act as the link between upstream resources and downstream users. Due to the pipes being buried underground for a long time, factors such as soil characteristics and topographical subsidence over time can lead to corrosion, perforation, and leakage, resulting in significant losses. Economic losses caused by construction and corrosion of oil and gas pipelines can be divided into direct and indirect losses. Direct losses include costs for replacing equipment and components, repairs, and anticorrosive pipeline costs; indirect losses include production losses, loss of products due to corrosion and leakage, losses from the accumulation or damage caused by corrosion by-products, etc. Indirect losses are much greater than direct losses and are difficult to estimate.

Three-layer polyethylene (3PE) coating structure combines the properties of fusion epoxy powder coating and extruded polyethylene corrosion protection layers. It integrates the interface characteristics and chemical resistance of the fusion epoxy powder coating with the mechanical maintenance properties of the extruded polyethylene corrosion protection layer, significantly enhancing the functionality of each. Therefore, it is an excellent external protective layer for buried pipelines. According to relevant materials, a three-layer PE coating can extend the lifespan of buried pipelines to 50 years.

1) There should be a smooth polyethylene section of 10-20mm without weld bead excess, identical to the pipe body, from the starting point of weld beveling to the polyethylene chamfer, to ensure the quality of the polyethylene beveling at the pipe end. 2) The weld bead excess after finishing should be as level as possible with the pipe body, avoiding any noticeable excess, to prevent the sanding of the polyethylene chamfer from also removing the epoxy powder. 3) The chamfer of the unwelded top end and the transition section to the finished area should also be the same as the polyethylene chamfer (≤30°), to allow the even application of pressure from the extrusion roller on the polyethylene layer, preventing warping of the polyethylene layer due to poor bonding of the anti-corrosion coating at the beveling area.

This anti-corrosion treatment is specifically designed for drinking water pipeline projects, ensuring no pollution and toxicity, which is a significant issue concerning the health of the general public. As part of our company's anti-corrosion workshop, we must always remember to avoid using substandard materials, substitute inferior for superior, and never compromise on the authenticity of our products, keeping the safety of the people's lives in mind at all times! The IPN8710 anti-corrosion steel pipe interpenetrating network heavy-duty anti-corrosion coating is a two-component coating, with the A component base material consisting of resin and initiator; the B component base material consisting of active monomers and catalysts. When the A and B components are mixed in equal proportions, the three networks interpenetrate at the molecular level, forming an interpenetrating polymer network (IPN) structure, which produces a synergistic effect. This coating's network features strong adhesion, excellent flexibility, and resistance to acidic, alkaline, and saline corrosive mediums.

Non-toxic anti-corrosion pipelines are crucial for the safe operation and lifespan of long-distance natural gas pipelines and gathering networks. The adoption and construction quality of external anti-corrosion pipeline technology directly affect pipeline safety and longevity. Due to the complex terrain and diverse soil properties in the areas where pipelines cross, different external anti-corrosion pipeline measures must be taken for buried steel pipelines. The main characteristics of the development of external anti-corrosion pipeline technology are reflected in the high performance, integration, long service life, and good cost-effectiveness of anti-corrosion pipeline materials. Since the IPN8710 interpenetrating network coating was introduced in China in 1987, it has undergone technical improvements using different resins and colorants to resist various corrosive mediums. It has subsequently developed specialized coatings such as anti-corrosion coatings for water pipelines, chemical industrial atmospheric corrosion coatings, gas storage cylinders, pipeline anti-corrosion coatings, oil storage tanks, and oil pipeline anti-corrosion coatings. The comprehensive properties of this series of coatings are as follows: 1. Simple surface treatment; 2. Excellent anti-corrosion performance; 3. Reasonable performance-to-price ratio.
