Detail of epoxy powder anti-corrosion spiral steel pipe

TPEP anti-corrosion spiral steel pipe manufacturer, 3PE outer 3PE inner sintered epoxy composite steel pipe (also known as TPEP anti-corrosion pipe) is an upgraded product based on outer polyethylene inner sintered epoxy composite steel pipe. It is currently the most advanced buried long-distance pipeline Antiseptic form. A self-developed fourth-generation new anti-corrosion production line for large-diameter pipelines. The outer wall uses a thermal fusion winding process. The bottom epoxy resin, the middle layer of adhesive, and the outer layer of polyethylene form a three-layer anti-corrosion layer. The inner wall uses thermal spray epoxy powder. In the anti-corrosion method, the powder is heated and sintered at high temperatures and then evenly coated on the surface of the pipe body.

TPEP composite steel pipe: The Chinese name is outer-wound polyethylene and inner-sintered epoxy anti-corrosion steel pipe. It is the fourth-generation anti-corrosion technology for long-distance water pipelines. As its full Chinese name shows: the outer wall of the pipe is made of polyethylene-wound 3 It adopts layer PE structure anti-corrosion technology, and the inner wall adopts hot-fusion epoxy anti-corrosion treatment. The usage standard reaches food grade. It is the highest quality transportation anti-corrosion pipeline in the true sense. Regardless of the anti-corrosion treatment technology inside and outside the pipeline, it has reached the most advanced level at present, and its service life can be Up to 50 years. Product introduction of TPEP anti-corrosion steel pipe manufacturer: The full name of TPEP anti-corrosion steel pipe is: outer-wound polyethylene and inner sintered epoxy anti-corrosion pipe. Name interpretation: outer-wrap polyethylene refers to the 3PE anti-corrosion treatment on the outer wall of the pipe, a total of 3 layers, a layer of epoxy powder, a layer of adhesive, and the last layer of polyethylene winding. Internal sintered epoxy refers to the anti-corrosion treatment of epoxy resin powder on the inner wall of the pipe. It refers to the use of high-temperature sintered production technology to wrap the ring Oxygen resin powder is used to coat the pipeline. The product solves the problem of adhesion of the outer single layer of polyethylene to the steel pipe. At the same time, the anti-corrosion standard of the inner wall reaches food grade.

The first step of the 3PE anti-corrosion steel pipe is a single layer of epoxy powder, which fundamentally ensures the anti-corrosion effect of the anti-corrosion steel pipe, and then proceeds to the next process: the adhesive three-layer structure polyethylene anti-corrosion layer (3PE) combines the sintered epoxy powder The excellent properties of both coatings and extruded polyethylene anti-corrosion layers combine the interfacial properties and chemical resistance properties of sintered epoxy powder coatings with the mechanical protective properties of extruded polyethylene anti-corrosion layers, thereby significantly improving their respective performance. Therefore, it is very superior as an outer protective layer for buried pipelines. According to relevant information, three layers of PE can extend the service life of buried pipelines to 50 years. Currently, it is considered an advanced pipeline of external anti-corrosion technology internationally. In our country, three-layer PE has been the first to be applied in oil and gas systems. Our country’s built Shaanxi-Beijing natural gas pipeline and Kushan-Shanxi oil pipeline, as well as the nearly 4,000 kilometers of pipelines for the recent national key project of west-to-east gas transmission, all use three layers of PE external anti-corrosion coatings.
