Straight seam high frequency welded steel pipe

Generally welded straight seam pipe to transport low pressure fluid. Made of Q215A, Q235A steel, Q235B carbon. It can also be manufactured in combination with easily weldable 0317 standard model 6012 and steel mother 755 mild steel. The pipe should carry out water pressure, bending, flattening and other experiments, and there are certain requirements for surface quality, usually the delivery length is 4-10m, and the delivery is often required to be measured (or double). The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two kinds of ordinary steel pipe and thickened steel pipe according to the specified wall thickness, and the steel pipe is divided into two kinds with thread and without thread according to the form of the pipe end.

use

Widely used in water, gas, air, oil and steam and other low pressure fluid transportation and mechanical structure.
