1. Impact toughness of large-diameter steel pipe: The load acting on the machine part at a high speed is called impact load, and the ability of the metal to resist damage under the action of impact load is called impact toughness.2. Strength of large-diameter steel pipe: Strength refers to the perfo

Thin-wall stainless steel pipe socket argon arc welding construction method has the following characteristics:1. The welding process does not require welding consumables (replaced by the expanded pipe edge). The steel pipe is inserted into the pipe fitting socket. The socket end is welded in a circl

1. The use of large-diameter stainless steel pipe can be divided into oil well pipes (casing pipes, oil pipes and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure chemical fertilize

Steel pipe anti-corrosion methods generally use coating anti-corrosion. Coating anti-corrosion is to apply coating uniformly and densely on the surface of the rusted metal pipe to isolate it from various corrosive media.1. Anti-corrosion coating on the outer wall of steel pipeThe anti-corrosion of t

Large-diameter straight seam welded pipe is a general name, which is produced by steel strips, and the pipes welded by high-frequency welding equipment are called straight seam welded pipes. (It gets its name because the welding of the steel pipe is in a straight line). Among them, according to diff

1. During the forming process of double-sided submerged arc welded spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and the surface is not scratched. The processed steel pipe has greater flexibility in diameter and wall thickness within the steel pipe size spec

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
