High-pressure alloy steel pipes are a kind of pipeline material widely used in various fields, and they play an important role in industries such as industry, construction, and energy. First, the application fields of high-pressure alloy steel pipes 1. Oil and gas industry: High-pressure alloy s

As an important building material, stainless steel pipes are widely used in industry, construction, chemical industry, medicine, and other fields. When choosing stainless steel pipes, one of the important parameters is the thickness of the pipe. First, the importance of stainless steel pipe thick

Steel pipe is a common building material, which is widely used in many fields. Among them, DN200 is a common steel pipe specification, which means that the nominal diameter of the pipe is 200 mm. 1. Characteristics of steel pipe DN200 Compared with steel pipes of other diameter specifications, s

Curling refers to the curling phenomenon that occurs on the edge of stainless steel pipes during the production process. It may have a certain impact on the quality and use of stainless steel pipes. First, the cause of the curling of stainless steel pipes 1. Production equipment problems: In the

Stainless steel is a metal material with excellent corrosion resistance. It is widely used in various fields, especially in the construction, chemical industry, food processing, and other industries. Among them, 304 stainless steel is the most commonly used material. It has excellent corrosion resis

42CrMo alloy steel pipe is a high-quality steel material, which is widely used in various fields with its excellent mechanical properties and durability. It is made of 42CrMo alloy steel, which has good hardness, strength, and corrosion resistance, and is suitable for use under harsh working conditi

Plastic-coated seamless steel pipe is a steel pipe with excellent anti-corrosion performance. Based on steel pipe production, a layer of plastic is coated on the surface of the steel pipe through a special process. This special plastic coating process gives the steel pipe excellent anti-corrosion ab

Round stainless steel pipes and square steel pipes are very common in life. Whether it is a national standard or a non-standard part, the amount of stainless steel used in these two shapes is comparable. There are still differences between round stainless steel pipes and square steel pipes, and it i

1. Introduction to Q390B steel plate: Q390B is a low-alloy high-strength structural steel. Q390B is not only a high-strength steel, but also a low-carbon steel. Q390B has high yield strength, good fatigue resistance, high toughness and low brittle transition temperature, good cold forming performanc

The production process of hot-rolled solid ingots is to roll them into hollow tubes with no seams around them. Carbon steel, alloy tubes, high alloy steel, and some non-ferrous metal seamless steel pipes can be produced by hot rolling, with an outer diameter range of 16 to 1600 mm and a wall thickne

First, material characteristics of large-diameter internal and external plastic-coated steel pipes: 1. Plastic coating layer: The inner and outer layers of large-diameter internal and external plastic-coated steel pipes are protected by plastic coating. This coating has good corrosion resistance an

Steel bending pipe processing forming process 1. 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. The die forging blank should be a rolled profile such as a bar,

1. Selection of raw materials for cold-drawn seamless steel pipes To save costs, some seamless steel pipe manufacturers will choose round steel produced by small steel mills for processing, but the round steel produced by these small steel mills will contain many impurities, bubbles, interlayers, p

First of all, we need to store the spiral steel pipes in the warehouse, not store them in the open air, and we need to ensure that the storage in the warehouse is clean. Tidy and well-drained. If there are weeds or other debris on the ground, they need to be cleaned and stored. This is to keep the s

As a common metal material, steel pipe is widely used in all walks of life. As one of the special material steel pipes, 40CR steel pipe has also attracted much attention for its performance and use. 1.40CR steel pipe material characteristics 40CR steel is an alloy structural steel with high stre

20Cr precision rolled steel pipe, as an important steel product, has a wide range of applications and unique advantages and characteristics. Below we will discuss in depth the characteristics, advantages, and applications of 20Cr precision rolled steel pipes in different fields. 20Cr precision ro

When welding steel pipes, the following preparations should be made for the steel pipe mouth: (1) Remove floating rust, dirt, and grease from the interface. (2) When the steel pipe is steam welded or mechanically cut, the cross-section should be kept straight to ensure the concentricity of the ste

304 stainless steel welded steel pipe has relatively good corrosion resistance, heat transfer efficiency, and high-pressure resistance. After the welds of 304 stainless steel welded steel pipes are welded, they must be pickled and passivated. The pickling and passivation of the welds are carried out
