Açıklama:

Straight seam high frequency (ERW) is divided into two forms: induction welding and contact welding according to different welding methods. It uses hot-rolled wide coils as raw materials and undergoes pre-bending, continuous forming, welding, heat treatment, sizing, straightening, cutting, etc. Compared with the spiral process, it has the advantages of shorter welds, high dimensional accuracy, uniform wall thickness, good surface quality, and high pressure resistance. However, the disadvantage is that it can only produce thin-walled pipes of small and medium diameters, and gray spots and lack of fusion are prone to occur at the welds. , Groove corrosion defects. At present, the most widely used fields are city gas, crude oil and refined oil transportation, etc.

Straight seam submerged arc (LSAW) is produced by using a single medium-thick plate as raw material, pressing (rolling) the steel plate in a mold or forming machine, and using double-sided submerged arc welding and diameter expansion. Its finished product specifications range is wide, the toughness, plasticity, uniformity and density of the weld are good, and it has the advantages of large pipe diameter, thick pipe wall, high pressure resistance, low temperature resistance and strong corrosion resistance. When constructing high-strength, high-toughness, and high-quality long-distance oil and gas pipelines, most of the required steel pipes are large-diameter, thick-walled straight seam submerged arc pipes. According to API standards, in large-scale oil and gas transmission pipelines, straight-joint submerged arc is the only designated applicable pipe type when passing through Class 1 and Class 2 areas such as alpine zones, seabed, and densely populated urban areas.

Farklı kalıplama yöntemlerine göre aşağıdakilere ayrılabilir:

UOE steel pipe: After the single steel plate is pre-bent at the edge, it undergoes processes such as U forming, O forming, internal welding, external welding, and mechanical cold expansion.

JCOE steel pipe: that is, pre-welding, forming, and cold expansion after welding according to "J-C-O-E"

HME steel pipe: formed by mandrel rolling method according to "C-C-O", welded and then cold expanded.
