Submerged Arc Welding Processing of Spiral Tube Formation

When processing spiral tube forming, pre-bending and sizing are the very major steps. Since the size of the rebound of tube blank affects the intrinsic quality of steel tube, here we adopt pre-bending as a cure to such problem. On the other…

Tin's modern application - Tin Plating

Tin, a white metallic element (chemical symbol 'Sn', atomic number 50, atomic weight 118.71) with over thousand years of application in human history, is now mainly used in the manufacturing of tinplates, which are widely related to our daily…

Overview of Steel Sheet Metal

One of the fundamentals in metalworking is the production and application of metal in the form of sheet metal or plates. Processed in thin, flat pieces, metal became more flexible in construction as sheet metal can then be bent and cut into…

From a chemical perspective: Tinplate

Tinplate consists of a steel plate coated with a thin layer of tin. Prior to the advent of cheap milling steel, the lining metal was iron. Although the use of tinplate is more extensive, its main use now is to make tin cans. Tinplate is made…

What is angle steel?

Definition of angle steel Angle steel is a strip of steel with two sides perpendicular to each other. There are two types of equilateral angle steel and unequal angle steel. The two sides of an equilateral angle are equal in width. Its specifications…

Steel bar for prestressed concrete projects

Steel bar introduction Steel bar refers to steel for reinforced concrete and prestressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. Including light round bars, ribbed bars, twisted bars. Steel…

What is seamless steel pipe

Definition of seamless steel pipe A steel pipe made of a single piece of metal without seams on the surface is called a seamless steel pipe. According to the production method, seamless steel pipes are divided into hot rolled tubes, cold rolled…

The knowledge of tinplate

The definition of tinplate Tinplate, also known as tin-plated iron, is a common name for electroplated tin steel sheet, with the English abbreviation SPTE, which refers to cold-rolled low-carbon steel sheet or steel strip coated with commercial…

Galvanized steel pipes production

Galvanized pipes are steel pipes dipped in zinc to prevent corrosion and rust. The zinc barrier proves equally effective against damage from indoor humidity. And galvanized pipes were usually installed in houses built before 1960s. Purpose…

The differences between galvanized steel pipes and general steel pipes

Galvanized steel pipes are divided into hot-dip galvanizing and cold-galvanizing. Hot dip galvanizing is the process of immersing the tube in a high temperature zinc bath to allow zinc to penetrate the surface of the steel. The surface of the…
