The steel required for liquid and gas transportation is generally seamless steel pipe, spiral welded pipe, and straight seam submerged arc welded pipe. Seamless steel pipes have uniform wall thickness distribution and high mechanical strength, which can withstand greater pressure. Widely used in fields such as petroleum, natural gas, and chemical engineering. The production cost of spiral welded pipes is relatively low, and the welded joints undergo special treatment to effectively prevent corrosion and oxidation. The steel required for liquid and gas transportation is generally seamless steel pipes, spiral welded pipes, and straight seam submerged arc welded pipes made of high-strength steel plates, which have high tensile strength and bearing capacity. After rust removal, painting and other treatments, their anti-corrosion performance and aesthetics are improved.
