The straight seam steel pipe refers to the steel pipe parallel to the length direction of the weld and the steel pipe. It is usually divided into public electric welding steel pipes, welding thin wall pipes, transformer cooling oil pipes, etc. The production process of vertical welding pipes is simple, the production efficiency is high, the cost is low, and the development is rapid. The strength of the spiral tube is usually higher than the intensity of the straight seam tube.
use
Used to transport low -voltage flow. Stranded steel pipes are mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, and urban construction. For liquid transportation: water and drainage. For gas conveying: gas, vapor, liquefied petroleum gas. Structural use: pile tube, bridge; docks, roads, building structure pipes, etc.
