‍(1) When the cooling is completed, that is, when the temperatures of the surface layer and the core are all consistent, the elastic deformation of the surface layer and the core will also disappear and return to the original state. Although instantaneous thermal stress is generated during the cooli

Advantages of seamless steel pipe:1. High precision: Seamless steel pipe is manufactured through a hot rolling process, leading to the higher precision of the pipe's dimensions and shape.2. Strong and durable: The absence of seams in seamless steel pipe makes it better able to withstand high pressur

1. High Strength: Seamless steel pipes are known for their high strength and are able to withstand high pressure and temperature, making them suitable for various industrial applications.2. Durability: These pipes are highly durable and have a longer service life, reducing the frequency of replaceme

TUBULAR CLEANINGInternal surface is cleaned by using high performance air compressor to remove mill scales and rusty inside the pipe. For Heavy Rusty on Internal surface, it will be removed by using special rotating tool connect with motor run inside the pipe to eliminate the rust on pipe ID surface

WHAT ARE STAINLESS STEEL SQUARE HOLLOW SECTIONS?The term Square Hollow Section is abbreviated as SHS. SHS steel is a popular variation of structural steel tube with four equal sides that give it a symmetrical appearance. It comprises a flat surface that makes joining and welding simple, and just min

1. Power supply with vertical external characteristics is adopted, and the positive polarity is adopted for direct current (the welding wire is connected to the negative electrode).2. Generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful weld shape and sm

Straight seam welded pipeStraight seam welded pipe is made of steel plate or steel strip after bending forming, and then through welding. Divided into the form of the weld seam welded pipe and spiral welded pipe by the welding forming method. According to the application, the straight seam weld pipe

Spiral pipe, also known as spiral steel pipe (SSAW), is a kind of tubular steel made of low carbon steel or low alloy steel through spiral welding process. Spiral pipe has the characteristics of high strength, good bearing capacity and excellent welding performance, so it has a wide range of applica

Commonly used welded steel pipes are divided into the following three types according to the welding process used in their production. ① Continuous furnace welding (forge welding) steel pipe: It is characterized by high production efficiency and low production cost, but the metallurgical combination
