The forging process generally consists of the following processes, that is, selecting high-quality billets for blanking, heating, forming, and cooling after forging. Forging methods include free forging, die forging, and membrane forging. During production, different forging methods are selected acc

1. For pipelines with high requirements for peak regulation, due to the uneven gas consumption of users and frequent fluctuations in pipeline pressure, the alternating stress on the steel pipe is very large, and the existing defects in the pipe will expand under the alternating stress. If you choose

In modern household water supply pipes, the corrosion resistance of water pipes is very important, because it means we can drink healthy and pollution-free drinking water. When PPR plastic pipes were promoted as tap water pipes, a test report from the Shanghai Disease Research Institute showed that

Usually, we use epoxy coal tar pitch paint, if the requirements are high, you can use 3 oils and 2 cloths. 3 layers of paint and 2 layers of the glass fiber cloth, staggered construction. If required, the primer and topcoat of epoxy coal tar pitch are generally used directly, and each is applied twi

Galvanized steel pipes are made of steel that has been covered with a layer of zinc metal. During the galvanizing process, we immerse the steel in a molten zinc bath, ensuring a tough, uniform barrier coating.Product name: galvanized seamless steel pipeSize: 219*5.5*12/273*6.0*12Application: Industr

1. The premise must be polishedThe galvanized layer at the weld must be polished off, otherwise, bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce rigidity.2. The welding characteristics of galvanized steelGalvanized steel is generally coated with a lay

Straight seam steel pipes are welded by a welding method parallel to the longitudinal direction of the steel pipes and are widely used. With the same diameter and length, the welding length of the straight seam steel pipe is much less, while the welding length of the spiral steel pipe may increase b

The hollow steel section comprises various material welded structural hollow sections for multiple purposes. No matter whether it is building construction, spare parts manufacturing, or even working parts construction. It is also used in these projects.Product name: square steel pipeSize: 400x200x9.

Steel bending pipe processing and forming process1. Die forging. For socket welding and threaded tees, crosses, elbows, and other small pipe fittings, the shapes are more complicated and should be manufactured by the die forging process, and the die forging blanks should be rolled profiles, such as

Spiral steel pipes are mainly used as fluid pipes and piling pipes. If the steel pipes are used for running water after they are made, they will generally be treated with anti-corrosion treatment on the inner or outer surfaces. The general anti-corrosion methods include 3pe anti-corrosion, epoxy coa
