/カテゴリ: /作成者:

Anti-corrosive steel pipe refers to a steel pipe that is processed by anti-corrosive technology and can effectively prevent or slow down the corrosion phenomenon caused by chemical or electrochemical reactions in the process of transportation and use. Anti-corrosion steel pipe is mainly used in domestic petroleum, chemical, natural gas, heat, sewage treatment, water sources, bridges, steel structures, and other pipeline engineering fields. Commonly used anti-corrosion coatings include 3PE coating, 3PP coating, FBE coating, polyurethane foam insulation coating, liquid epoxy coating, epoxy coal tar coating, etc. What is fusion bonded epoxy (FBE) powder anti-corrosive coating? Fusion-bonded epoxy (FBE) powder is a kind of solid material that is transported and dispersed by […]

The material, diameter, wall thickness, and quality of a specific service determine the pipe manufacturing process. Carbon steel piping is classified according to the manufacturing methods as follows: Seamless Electric resistance weld (ERW) Spiral-submerged arc weld (SAW) Double submerged arc weld (DSAW) Furnace weld, butt-welded, or continuous weld Seamless Steel Pipe Seamless pipe is formed by piercing a solid, near-molten steel rod, called a billet, with a mandrel to produce a pipe without seams or joints. The figure below depicts the manufacturing process of seamless pipe. ERW Steel Pipe ERW pipe is made from coils that are cupped longitudinally by forming rolls and a thin-pass section of rolls that brings […]
