What Are The Characteristics of Straight Seam Steel Pipe Welding Compared with Seamless Steel Pipe

1. The production process is simple.
2. Less equipment, simple structure, lightweight, easy to realize continuous, automatic, and mechanized production.
3. Low product cost.
4. It is suitable for a wide range of varieties and specifications, with a diameter of 6-3100mm and a wall thickness of 0.3-35mm.

Forming and welding are the basic processes of welded steel pipe production, and the production methods of welded pipes are classified according to the characteristics of these two processes. According to the welding method, it can be divided into four types: furnace welding, electric welding, gas welding, and gas-electric welding. Furnace welding is divided into lap welding and butt welding according to the weld form. The forming methods of butt welding are divided into two types: drawing and rolling. The equipment used for drawing has two types: chain furnace welder and continuous furnace welder. Roll forming adopts a continuous roll machine. Electric welding is divided into three types: contact welding, induction welding, and arc welding. Contact welding is divided into resistance welding and flash welding. Arc welding is divided into open arc welding, submerged arc welding, and shielded arc welding, and submerged arc welding is divided into There are two types of straight seams and spiral seams. Gas welding is divided into acetylene welding and water-gas welding. The water-gas welding equipment is divided into roller type pipe welding machine and forging type pipe welding machine. Gas electric welding is hydrogen atom welding.
