Welded pipe refers to the pipe made by crimping molding and welding process through steel plate or steel strip, its main characteristics are: the pipe has rectangular, round and oval section shape, thickness is also different; The length can be customized according to customer requirements, generally around 6m. According to different production processes and application needs, welded pipes can be divided into long welded pipes, spiral pipes and stainless steel welded pipes and other types.

The billet used for welding steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding process. Because of its different welding forms are divided into straight seam welded pipe and spiral welded pipe two kinds. Because of the shape of its end, it is divided into circular welded pipes and special-shaped (square, flat, etc.) welded pipes.
The production process of straight welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of spiral welded pipe is generally higher than that of straight welded pipe, and welded pipe with larger diameter can be produced with narrower billet, and welded pipe with different diameter can also be produced with billet of the same width. However, compared with the straight seam pipe of the same length, the weld length is increased by 30 to 100%, and the welded pipe with a large diameter or a thicker diameter is generally made directly of steel billet, while the thin wall welded pipe only needs to be directly welded through the steel strip.
In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
