Spiral pipe is a commonly used material in spiral pipes. It is a spiral seam steel pipe that is made of strip steel coils as raw materials, extruded at regular temperatures, and welded by automatic double-wire double-sided submerged arc welding technology.
./ is made of hot-rolled steel strip coils as pipe rings, often heated and spirally formed, and made by double-sided automatic submerged arc welding or single-sided welding. It is used for general low-pressure liquid transportation such as water, gas, air, and steam. Use submerged arc welded steel pipe. / is the petroleum ministry standard, generally called the ministry standard. Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation () is a submerged arc welded steel pipe made by double-sided automatic submerged arc welding or single-sided welding for general low-pressure fluid transportation such as water, gas, air, and steam.
