In engineering, industry, chemical industry or home, pipe insulation is the most common way, and the closest thing to life is the insulation of heating pipes. Polyurethane direct-buried insulation pipes are used in thermal and cold insulation projects for various indoor and outdoor pipelines, central heating pipelines, central air-conditioning pipelines, chemical industry, medicine and other […]
Long-distance oil and gas pipelines are an important means of energy security. During the anti-corrosion construction process of oil (gas) pipelines, the surface treatment of steel pipes is one of the key factors that determine the anti-corrosion service life of the pipelines. It is the prerequisite for whether the anti-corrosion layer and the steel pipe […]
Polyurethane insulation pipe, which is the full name of high-density polyethylene plastic outer protective polyurethane foam prefabricated direct-buried insulation pipe, is formed by connecting the working medium pipeline, polyurethane insulation layer and polyethylene plastic outer protective pipe that transports the medium through the equipment. Forming. Polyurethane insulation pipes are widely used. It has the following […]
Anti-corrosion steel pipe is a new type of steel pipe, after anti-corrosion treatment, it can effectively prevent or slow down the corrosion of chemical or electrochemical reactions during transportation and use; however, it is an excellent anti-corrosion steel pipe, please pay attention when using it; keep it warm , especially in the cold winter, In […]
TPEP anti-corrosion steel pipe (T, the initial letter of three-layer English Three, PE refers to polyethylene, EP refers to epoxy resin) is based on the outer 3PE inner fusion-bonded epoxy anti-corrosion steel pipe and the outer single-layer polyethylene inner epoxy composite steel pipe. The upgraded product is the steel pipe anti-corrosion form commonly used in […]
Proceso anticorrosión común de los tubos de acero anticorrosión Los tubos de acero anticorrosión se refieren a los tubos de acero que han sido procesados por la tecnología anticorrosión, que puede prevenir o ralentizar eficazmente el fenómeno de la corrosión causada por reacciones químicas o electroquímicas durante el transporte y el uso. Tubo de acero anticorrosivo ordinario 3PE se refiere a la estructura de 3 capas de revestimiento de poliolefina (MAPEC) [...]
The buried pipeline adopts the transmission line iron tower of plastic-coated steel pipe, which is composed of towers connected by tower pole devices. The tower is made of section steel. The steel surface of the tower rod and the inner and outer surfaces of the tower rod are hot-dipped with a modified polyethylene plastic layer. […]
Epoxy powder coating is applied by electrostatic spraying process, forming a film at one time. This epoxy powder coating is a kind of thermosetting coating, which is processed by mixing and destroying solid epoxy resin, curing agent and various additives. The steel pipe is preheated by shot blasting and intermediate frequency before painting, and then […]
After the surface is mechanically damaged, the anti-corrosion spiral steel pipe must be repaired. When the scratches do not cause leakage, the two circular fillet welds between the casing and the steel pipe body do not need to be welded. If it leaks, it needs to be welded. The sleeve is directly subjected to the […]
The quality requirements of galvanized square tubes are very high. However, due to the inevitable corresponding quality defects in each process of steel pipe production, and some steel pipes are in service under some special environmental conditions, in addition to the overall performance of the steel pipe, the accuracy of the outer diameter and wall […]
