Characteristics and applications of thick-walled pipes

Thick-walled pipes are steel pipes with larger wall thickness. They mainly have the characteristics of high strength, corrosion resistance, and strong load-bearing capacity. They are widely used in pe

Thick wall coiled tube

Thick-walled coiled pipes are made of steel plates. Thick-walled coiled pipes can be divided into cold-rolled thick-walled coiled pipes, hot-rolled thick-walled coiled pipes, and cold-rolled thick-wal

High pressure boiler tube

High-pressure boiler tubes (20G, 15CrMo, 12Cr1MoVG) can be cut for retail. High-pressure boiler tubes (20G, 15CrMo, 12Cr1MoVG) are widely used in industrial production.

Fertilizer Tube: GB/T 6479 Seamless Steel Pipe for High-Pressure Chemical Plants

A fertilizer tube is a GB/T 6479 seamless steel pipe for the high-pressure process loops of ammonia, urea and methanol plants, supplied in grades 20, 16Mn, 12CrMo and 12Cr2Mo. This guide covers the gr

Line pipe

Line pipes transport oil, gas or water pumped out of the ground to oil and natural gas industrial enterprises through line pipes. Line pipes include seamless and welded pipes, and their pipe ends incl

Structural Strengthening of High-Pressure Alloy Steel Pipe: Matrix Phase and ...

Structural strengthening of high-pressure alloy steel pipe depends on the matrix phase, the deformation stored in the material and the cooling environment applied after forming. This article explains

Characteristics of low alloy steel

Low alloy steel is an alloy steel containing smaller amounts of non-ferrous elements (such as silicon, chromium, molybdenum, etc.).

Welding method

According to the energy and process characteristics used, welding is divided into three categories: fusion welding, pressure welding and brazing, and each category is divided into various welding meth

Difference between casting and forging flanges

Cast flange, the rough shape and size are accurate, the processing volume is small, and the cost is low, but there are casting defects (pores, cracks, inclusions); the internal structure of the castin
