Plastic coated composite steel pipe
Polyurea anticorrosive elbow
Polyurea anticorrosive elbow:
Production processing range φDN80—ΦDN1400
The future development of polyurea anticorrosive elbow polyurea coating represents the latest international anticorrosion technology trend. At present, major international pipeline companies have used polyurea anticorrosive coatings. For example, the oil pipelines in Alaska, the Gulf oil pipeline in Indonesia, the Siberian oil pipeline in Russia, and the water pipeline in Kuwait all use polyurea as anticorrosive coatings.
Polyurea is an elastomer substance formed by the reaction of isocyanate component and amino compound component. Divided into pure polyurea and semi-polyurea, their performance is different, the most basic characteristics of polyurea are anti-corrosion, waterproof, wear resistance, etc.
The advantages of polyurea anticorrosive elbow:
Polyurea anticorrosive elbow material used for pipe joints has excellent construction performance. Generally, straight pipes are prefabricated in the factory, and the joints are spouted and connected on site. After the polyurea treatment, the pipeline can maintain good continuity and integrity, so that the entire pipeline system is sealed and seamless, ensuring the overall anti-corrosion function and long life of the pipeline.
Product features of polyurea anticorrosive elbow:
Fast curing speed, no sagging in facade and curved construction; excellent corrosion resistance, can withstand the erosion of most chemical media; excellent physical properties, good adhesion to metal substrates; 100% solid content, no Pollution and environmentally friendly; the coating has no seams, completely avoiding the hidden danger of leakage.
The main purpose of polyurea anticorrosive elbow:
Anticorrosion of the inner and outer walls of overhead pipelines, directly buried pipelines, oil pipelines, gas pipelines, municipal sewage pipes and various steel pipelines

According to international standards, buried metal pipelines are protected by a combination of anti-corrosion layer and cathodic protection. The pipeline anti-corrosion layer is the first barrier. 3PE anti-corrosion layer combines the advantages of high-density polyethylene coating and fusion-bonded epoxy powder, and has been widely used at present. The main disadvantage is that the patching problem has not been solved, and the heat shrinkable sleeve used does not match the 3PE, which greatly affects its service life.
