A detailed explanation of the welding process of large diameter straight seam steel pipe:The double-wire automatic welding of straight seam steel pipe is a welding technology developed in recent years. In addition to the characteristics of semi-automatic single-wire welding, it also has the welding

Acceptance of straight seam steel pipe:1. The inspection and acceptance of straight seam steel pipes shall be carried out by the technical supervision department of the supplier.2. The supplier ensures that the delivered straight seam steel pipe meets the requirements of the corresponding product st

After the oil casing adopts this heat treatment method, the impact toughness, tensile strength, and anti-destruction performance of the oil casing can be effectively improved, and the good value in use can be guaranteed. Oil casing is a necessary pipe for drilling oil and natural gas, and it needs t

With the wide application of stainless steel pipes, people's requirements for them are getting higher and higher, and the processing technology has also become diversified. Pickling is one of the processing techniques. Do you know why hydrogen embrittlement occurs in stainless steel tubes after pick

1. The importance of anti-corrosion of long-distance natural gas anti-corrosion steel pipesAt this stage, both domestically and foreign, the demand for natural gas is gradually increasing, among which natural gas has become an irreplaceable and important energy source. In this case, the demand for n

Welded steel pipes can be classified into different types and types according to different classification methods. Welded steel pipes of different properties have different characteristics and characteristics in use and show different use values in use. Welded steel pipes can be classified into the

Simply put, the process of heating the steel pipe and controlling it to be above the recrystallization temperature for rolling is called hot rolling. The process of rolling below the recrystallization temperature, including normal temperature, is called cold rolling.Hot-rolled steel pipe has good pl

1. Spiral steel pipes shall not be stacked with acid, alkali, salt, cement, and other materials that are corrosive to steel in the warehouse. Different varieties of steel should be stacked separately to prevent confusion and contact corrosion;2. Large sections, rails, steel plates, large-diameter sp
