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

There are significant differences between straight seam steel pipes and steel pipes. I believe that many people must think that the two are similar in terms of usage and performance. Straight seam steel pipes are higher than steel pipes. The better types sold in the market are electric welded steel

The main process parameters of high-frequency straight seam welded pipe include welding heat input, welding pressure, welding speed, opening angle, position and size of the induction coil, position of impedance, etc. These parameters have a greater impact on improving the quality of high-frequency w

Spiral welded pipes and straight seam welded pipes have different technical characteristics and production processes. They have many differences and differences in production, have different functions and uses, and their values in use are also different.The first is the difference in the welding pro

Steel flange is a commonly used flange technology, which has the advantages of high production efficiency and low production cost, and is suitable for medium and low-pressure pipelines. Forged pipes are recommended for pipes operating at high pressures.Product name: Steel FlangeSize: 15''Standard: A

1. Different definitions:Long-radius steel elbow: Long-radius steel elbow means that the radius of curvature of the elbow is 1.5 times the diameter of the pipe; if it is greater than 1.5 times, it is in the category of elbows.Short radius steel elbow: The short radius steel elbow means that the radi

Spiral steel pipe and steel coil pipe are both welded steel pipes, and the production process of the two is very different. Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submer

1. Welding process: In the welding process, the welding method of the spiral steel pipe and the straight seam welded pipe is the same, but the straight seam welded pipe will inevitably have many T-shaped welds, so the probability of welding defects is greatly increased. The welding residual stress i
