Straight seam steel pipe - Straight seam steel pipe - Straight seam steel pipe specifications

Straight seam steel pipe - Straight seam steel pipe use - Straight seam steel pipe specifications Straight seam steel pipe is a longitudinally parallel steel pipe of the weld seam. Usually divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on. The straight seam welded pipe has a simple production process, high production efficiency, low cost, and rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe. A narrower blank can be used to produce a larger diameter pipe, and a blank having a different diameter can also be produced using a blank of the same width. However, compared with the straight seam pipe of the same length, the length of the weld seam increases by 30 to 100%, and the production speed is low.

Straight seam steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid transport: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. Used for structural purposes: as a pile driving pipe, as a bridge; piers, roads, building structures, etc.
