Straight seam steel pipe refers to a steel pipe in which the weld seam is parallel to the longitudinal direction of the steel pipe. It is also generally called straight seam welded pipe or straight seam steel pipe. Straight seam pipes are made by rolling long strips of steel strips of a certain specification through high-frequency welding units and using straight seam welding. The specifications of straight-seam pipes are expressed in nominal diameter. According to the wall thickness, they can be divided into two types: thin-walled straight-seam pipes and thick-walled straight-seam pipes. According to the shape, it can be divided into round, square or special-shaped tubes. Usually divided into metric electric welded steel pipes, electric welded thin-walled pipes, transformer cooling oil pipes, etc. The production process of straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Welded pipes with larger diameters can be produced from narrower billets, and welded pipes with different diameters can also be produced from billets of the same width. However, compared with straight seam pipes of the same length, the weld length is increased ~., and the production speed is lower. Straight seam steel pipes can be divided into high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes according to the production process. Submerged arc welded straight seam steel pipes are divided into steel pipes, steel pipes, etc. according to their different forming methods. The following introduces the most common forming processes of high-frequency straight seam steel pipes and submerged arc welded straight seam steel pipes.
Usage: Straight seam steel pipes are mainly used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.
For liquid transportation: water supply and drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. Structural use: used as piling pipes, pipes for bridges, docks, roads, building structures, etc. Product features: The straight seam high-frequency welded steel pipe has small rebound and small residual stress during the forming process. The deformation hardening effect is small, and the geometric dimensions after rounding are accurate, which is beneficial to ensuring construction and welding quality. The straight seam high-frequency welded steel pipe weld bead has a good shape and is not prone to defects such as undercuts and misalignment of internal and external welds. The straight seam steel pipe weld bead is distributed at one point on the circumference, so the weld can be placed at a favorable position according to the usage requirements.
