Introduction to knowledge of seamless steel pipes

Seamless steel pipes are made of steel ingots or solid tube billets through perforation into capillaries, and then made of hot-rolled, cold-rolled or cold-drawn. The mold production company will use it to make mold steel. Seamless steel pipes are made of high-quality carbon steel or alloy steel, and are divided into hot-rolled and cold-rolled (drawn). […]

The function of hot dip coated steel pipe

The function of hot dip coated steel pipe The function of hot-dip plastic steel pipe Hot-dip plastic steel pipe is a new type of anti-corrosion steel produced by fluidized bed dip coating process and one-time film forming process, which is an upgrade to the original plastic coated steel pipe or electrostatic spray pipe. The hot […]

The difference between steel-plastic composite pipe and plastic-lined steel pipe

Steel-plastic composite pipe and plastic-lined steel pipe have always been foolishly confused between the two kinds of pipes, do not know their respective properties, and do not know where they are used respectively. In fact, the difference between steel-plastic composite pipe and plastic-lined steel pipe is quite Big, you can’t see that the main reason […]

What is the difference between electro-galvanized sheet and hot-dip galvanized sheet?

Hot-dip galvanizing: also known as hot-dip galvanizing and hot-dip galvanizing: it is an effective method of metal anticorrosion, mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ° C, so that the surface of the steel parts adheres to […]

What is the difference between carbon steel pipe and stainless steel pipe and seamless steel pipe

Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes. In addition to […]

Manufacturing methods and main uses of seamless pipes

What is a seamless tube? It is a type of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as that of seamless steel pipes, but there are certain strict requirements for the steel grades used to manufacture steel pipes. Since seamless pipes are often used in […]

Matters needing attention when storing seamless steel pipes

Seamless steel pipe is a pipeline that is widely used to transport fluids, such as natural gas, oil, and water. Seamless steel pipes can be divided into hot-rolled seamless steel pipes and cold-rolled seamless steel pipes. Seamless steel pipes are widely used in the manufacture of structural parts and mechanical parts, such as automobile transmission […]

Straight seam steel pipe is used for localization of petrochemical pipelines and other materials

The pipeline company is in the process of pipeline renovation by revising the technical specifications. Imported pumps are introduced to replace DKS-750/550 pumps which are bulky and have low pumping efficiency, and the pumping efficiency is greatly improved. During the construction of the Yichang crude oil pipeline project, on the basis of imports, the pipeline […]

Hot-rolled sheet, cold-rolled sheet, and galvanized sheet What are their respective application industries

Hot-rolled sheet Hot-rolled sheet is the most important type of steel in the sheet, and is widely used in industrial production industries such as containers, automobiles, railway locomotives, pipes, and steel cylinders. Hot rolled sheets are mainly rolled by continuous hot rolling mills. The hot-rolled sheet finally rolled by the continuous rolling mill can also […]

How to distribute the basic oxidation performance of 16mn precision steel pipe

16mn precision steel pipe has the advantage of resource advantages. Because its surface is not easily oxidized by air, the key is inseparable from the raw materials that constitute 16mn precision steel pipe. The precision stainless steel tube is a very thin, firm and smooth chromium-rich air oxide film (safety protective film) produced on its […]
