Welding process in the form of pipes Welded steel pipe, also known as, is a steel pipe with steel or steel welding after curling molding made. Welded steel pipe production process is simple, high production efficiency, variety specifications, less capital equipment, but the general strength of less than seamless steel tubes.

Longitudinal production process is simple, high efficiency, low cost, rapid development. Spiral Welded Longitudinal generally higher than that, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters. However, compared with the same length of straight seam pipe, weld length of 30 to 100%, and lower production rate. Therefore, smaller diameter pipe is mostly a straight seam welded, large diameter spiral welded pipe is mostly used. Ordinary carbon steel wire casing for industrial and civil construction, installation of machinery and equipment for the protection of electrical installation engineering steel wires.

General low pressure liquid delivery spiral submerged arc welded pipe is hot-rolled steel strip coils for the tube, often warm spiral shape, using double-sided or single-sided automatic submerged arc welded into the legal system for water, gas, air and steam low pressure liquid delivery SAW pipe. Straight seam welded steel pipe and steel pipe is parallel to the longitudinal weld pipe. Usually divided into metric welded steel pipe, welded tube, transformer cooling pipes and so on. Pressure liquid delivery spiral submerged arc welded pipe is hot-rolled steel strip coils for the tube warm spiral shape, with double-sided submerged arc welding method for spiral seam steel pressure fluid transfer.

Strong pressure steel, good welding performance, through a variety of rigorous scientific examination and testing, the use of safe and reliable. Pipe diameter, high transmission efficiency, and can save the laying of pipeline investments. Mainly used to transport oil, natural gas pipelines. Pile with spiral welded steel pipe is hot-rolled steel strip coils for the tube, carbon seamless steel pipe manufacturer china often warm spiral shape, using double-sided submerged arc welding or high frequency welding made for civil engineering structures, piers, bridges and other infrastructure with steel piles .

General low pressure fluid with high-frequency spiral welded steel pipe is hot-rolled steel strip coils for the tube, often warm spiral shape, using high frequency lap welding method for general low pressure liquid delivery spiral seam high frequency welded steel pipe.

Pressure transmission fluid with high-frequency spiral welded steel pipe is hot-rolled steel strip coils for the tube, often warm spiral shape, lap welding method using high-frequency welding, pressure fluid transfer for high-frequency spiral welded steel pipe . Strong pressure steel, plastic, and easy welding and machining molding; through a variety of rigorous and scientific inspection and testing, safety and reliability, pipe diameter, high transmission efficiency, and save the laying of pipeline investments. Mainly used for laying transport oil, natural gas pipeline.
