Many people, do not know under what circumstances stainless steel pipe fittings need to be selected for welding technology, so the next step is to look at it step by step to facilitate the selection of welding technology in the future.1. Argon arc welding is a welding technology that uses argon gas
Spiral welded pipe and straight seam welded pipe have different technical characteristics and production processes. There are many differences and differences in production, different functions and uses, and different values in use.Below, we make a simple comparison of the technical characteristics
The production process of galvanized straight seam welded pipe is relatively simple. The main production processes include high-frequency welded straight seam steel pipe and submerged arc welded straight seam steel pipe. Straight seam pipe has high production efficiency, low cost, and rapid developm
Processing and forming process of steel elbow1. Die forging. For socket welded and threaded tees, crosses, elbows, and other small pipe fittings, the shape of which is more complex and should be manufactured by a die forging process, the die forging blank should be a rolled section such as bar, thic
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
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
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
The special oil pipe is mainly used for the drilling of oil and gas wells and the transportation of oil and gas. It includes oil drilling pipes, oil casings, and oil-sucking pipes. Oil drill pipes are mainly used to connect drill collars and drill bits and transmit drilling power. The oil casing is
The use and function of large diameter straight seam welded pipe1. The use of large-diameter straight seam welded pipes can be divided into oil well pipes (casing, oil pipes, drill pipes, etc.), line pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geologica
The performance and function of the primary color straight seam steel pipe in the specific use process, the fully demonstrated operational contribution, and the resulting use performance, after painting, spraying white words, the straight seam steel pipe also looks very spiritual and beautiful. Pipe
