Process the sides of the two plates into the required form at one time, steel plate edge milling machine: machine the two sides of the plate used for pipe making, and make the parallelism of the two plates within the specified tolerance range, to manufacture high-precision Steel pipes are prepared.

The continuous rolling process of straight seam steel pipe: the continuous rolling process of straight seam steel pipe, continuous rolling process is used in the continuous rolling and fixed diameter reduction process of steel pipe. Continuous steel pipe rolling is a process in which steel pipes and

During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter and wall thickness, especially when producing high-grade

For the coated steel pipe material to choose, that will be more important. Good anti-corrosive material will protect the steel pipe for a long lifetime. Here is the coated steel pipe material that usually chooses in the anti-corrosive. Anti-corrosive pipeline materials mainly include 2/3P anti-corro

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
