Spiral steel pipe
Spiral Pipe is made of a strip coil , often extrusion molding under nature temperature, to be welded with the automatically double-sided submerged arc welding process .It usually used in Public waterwork systerm,Petroleum,Chemical,Power plant,Agriculture irrigation,City construction etc ., transporting fluid and gas and mechnical tube .
Thermal expansion pipe
thermal expansion is a processing method for steel pipe,which means processing the small diameter pipe into large diameter . Thermal expansion pipe specifications are usual optional,generally based on the needs of customers demands.And the thermal expansion steel pipe is low density but with strong contraction, (seamless steel pipe) can be referred to as thermal expansion pipe.
Seamless steel pipe
Seamless steel pipe is the pipe with a hollow cross section and no seams rim around,usually have rounded, square, and rectangular 3 shapes. Seamless steel is made of steel ingot or solid tube ,which be perforated to be hollow billet, and then processed by hot-rolled, cold-rolled or cold-call .
Straight steel pipe
Straight steel pipe is the pipe whose longitudinal weld parallel to the steel pipe.Usually divided into metric welded steel pipe, welded thin-walled tube, transformer cooling pipes and so on. Its production process is simple, high efficiency, low cost.
