BLACK PIPE

Features :

• Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development.
• The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be used to produce welded pipes with larger pipe diameters, and a billet with the same width can also be used to produce welded pipes with different pipe diameters.
• But compared with the straight seam pipe of the same length, the weld length is increased by 30-100%, and the production speed is lower.

Application :

• Black steel pipe are widely used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction.
• For liquid transportation : water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas.
• For structural purposes : as piling pipes and bridges; pipes for docks, roads, and building structures.
