The finished product of seamless steel pipe precision steel pipe will have the problem of uneven thickness or eccentricity, but how does it happen? Many people don't understand. Today, let's talk about how the eccentricity of seamless steel pipes such as cold-drawn steel pipes, cold-rolled steel pip
Thick-walled steel pipes and thin-walled steel pipes have a big difference in the thickness of the pipe wall. The diameter of the steel pipe wall is greater than 0.02, we generally call it thick-walled steel pipe. Thick-walled steel pipes have a very wide range of applications. Due to their thicker

The fire pipeline includes two systems: a fire hydrant system and a water sprinkler system.The stainless steel fire-fighting piping system is a fixed fire-fighting facility widely used in China. Nowadays, the fire water supply pipes in the water sprinkler system use 304 stainless steel pipes. As we
The straight seam steel pipe is a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. It is usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe, and so on. The production process of straight seam w
The inner and outer surfaces of the large-diameter welded pipe of the spiral seam submerged arc welded pipe should be bright, and there should be no residual acid and oxide scale. Surface defects should be removed by grinding, the grinding place should have a smooth transition with the base material
Long-distance oil and gas pipelines are an important way to ensure energy. In the process of anti-corrosion construction of oil and gas pipelines, the surface treatment of straight seam steel pipes is a key factor in determining the service life of pipeline anti-corrosion. It is the premise of wheth
Project Location: Colombia.Product: ERW STEEL PIPE.Specifications: 150mmNB.Application: the steel pipeline will be in different districts for energy transport.Arrival time: 06.15.2022.The pipes have arrived in Colombia and were put into project use.Many cooperations have given the customer full conf
304 stainless steel pipe is the most widely used as stainless heat-resistant steel, food equipment, general chemical equipment, and atomic energy industry equipment. 304 stainless steel pipe is a general-purpose stainless steel pipe, which is widely used to make equipment and parts that require good
At present, there are two standards for 3PE anti-corrosion steel pipes, namely GB/T 23257-2009 and GB/T 23257-2017. GB/T 23257-2017 is a new standard and was implemented in December 2017. The two standards differ mainly in the following aspects:3PE anti-corrosion steel pipe1. The design temperature
