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

There are two possibilities for the formation of surface defects in the spiral steel pipe: one is that the plasticity of the spiral steel pipe is not good during the deformation process, resulting in cracks and outward folds; the other is that the surface of the spiral steel pipe is oxidized to caus

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

Product: SSAW steel pipeApplication: Energy Construction Industry ProjectProduct arrived location: VietnamQuantity: 30 TonThe order is from an old client, who needs to applicate for an energy construction industry project. This project is power plant construction. These SSAW steel pipes with large d

Thick-walled steel pipe production steps:1. The stainless steel elbow is made of thick-walled steel pipe, and the wall thickness changes along the length of the pipe;2. Process the section of the square tube, and change the circular area into a square, oval, and polygon;3. For square pipes with crim

Thick-walled steel pipes are specified in the project:Corresponding regulations and various regulations for the practical selection and use of thick-walled pipe fittings. When thick-walled steel pipe and thick-walled pipe fittings are selected or used, they must first follow the corresponding regula

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

Product: Boiler steel pipeApplication: heat exchangeProduct arrived location: FranceSize:50X3.6X7856mmThe order is from an old client, who needs to replicate the heat exchange project. When the product arrived in the industry project, it was quickly put into the project.

①Advantages of material propertiesThe thin-walled stainless steel pipe is made of stainless steel as the name implies. The strength of stainless steel is 3 times that of copper pipe and 8 to 10 times that of PPR pipe. It can withstand the impact of high-speed water flow of 30 meters per second; Espe
