Most of the structural seamless steel pipes work under relatively large dynamic loads. They are subjected to tension, compression, bending, torsion or shearing. Some surfaces also have friction, requiring certain wear resistance and so on. In summary, parts operate under various compound stresses. Structural seamless steel pipes are mainly structural parts of various machines and mechanisms, such as shafts,…
Read MoreThe production method of seamless steel pipe is roughly divided into the cross-rolling method and the extrusion method. The former method is to pierce the tube with oblique rolls and then stretch it with a rolling mill. This method has a fast production speed, but has higher requirements on the processing performance of the tube blank, and is mainly…
Read MoreHot-dip galvanizing is a process in which a metal material or part with a clean surface is immersed in a molten zinc solution, and a layer of metal zinc is formed on the surface through a physical and chemical reaction at the interface. Hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method,…
Read MoreComparison of ERW pipe and seamless pipe (SMLS): (1) Superior tube blank quality Compared with the tube blank of SMLS steel pipe, the design of chemical composition of high frequency welded pipe (ERW) is more scientific and reasonable. ERW special steel grades are characterized by high purity. Through de-S, de-P, degassing, Ca treatment and other methods, the content of…
Read MoreThe quality and performance of seamless pipes are determined according to needs. According to different needs, different element contents and types must be matched with them. (1) Carbon: The higher the carbon content, the higher the hardness of steel, but the worse its plasticity and toughness. (2) Sulfur: It is a harmful contaminant in steel. When steel with high…
Read MoreDue to the continuous development of urbanization construction, materials in the building materials market have emerged one after another. Although these materials are relatively common in our daily life, people who do not usually run in the building materials market may not know carbon steel. today I will explain to you what kind of material carbon steel is? And…
Read MoreWhat is carbon steel pipe? Carbon steel pipe is also called CS pipe. Carbon steel pipes are made of steel ingots or solid round steels through perforation into capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. Carbon steel pipe plays an important role in my country’s steel pipe industry. Types of carbon steel pipes: Carbon steel pipes are…
Read MoreSelection criteria for high frequency welded pipe (ERW) welding consumables Classification of welding rods: (1) Classification by slag properties Welding electrodes can be divided into two categories: acid electrodes and alkaline electrodes. The electrode whose slag is mainly acid oxide is called acid electrode. The electrode whose slag is mainly alkaline oxide and calcium fluoride is called alkaline electrode….
