(1) Hydrostatic test: The expanded steel pipe is inspected one by one on a hydraulic test machine to ensure that the steel pipe reaches the standard required test pressure. The machine has automatic recording and storage functions; (2) Expansion: Expand the diameter of the submerged arc steel pipe to improve the dimensional accuracy of the steel pipe and improve…
Read More3PE anticorrosive steel pipe base materials include seamless steel pipe, spiral steel pipe and straight seam steel pipe. Anti-corrosion pipelines can be divided into two categories, lined with anti-corrosion steel pipes and outer-wall anti-corrosion steel pipes. The lining anti-corrosion mainly includes cement mortar-lined anti-corrosion steel pipe, which has more applications and lower cost. The cement mortar-lined anti-corrosion steel pipe…
Read More1.Main types of anti-corrosion spiral steel pipe: Common forms of anti-corrosion spiral steel pipes are mainly 3PE anti-corrosion, epoxy resin anti-corrosion, cement mortar anti-corrosion and epoxy coal asphalt anti-corrosion. 2.Main features of anti-corrosion spiral steel pipe: 3PE anticorrosion is mainly for oil and natural gas pipelines, because oil and natural gas pipelines require high price comparison, 3PE anticorrosion can…

Read MorePiling spiral steel pipe(SSAW) is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. So, what is the piling spiral tube like during construction? How is the piling spiral tube produced? The following spiral tube manufacturers will introduce to you. 1. Penetration of piling…
Read MoreCauses of wrong edges of large-diameter spiral steel pipes (SSAW): In the production of large-diameter spiral steel pipes, misalignment occurs from time to time, and there are many influencing factors. In production practice, steel pipes are often degraded due to dry misalignment and out-of-tolerance. Therefore, it is necessary to analyze the causes of wrong edges of large-diameter spiral steel…
