1. Pressure transmission fluid spiral steel pipe spiral Welder submerged arc welded pipe (SY5036-83) in the hot-rolled steel strip coils for the tube, often warm spiral shape, with double-sided submerged arc welding method for pressurized fluidconveying spiral pipe joints. Strong pressure steel, good welding performance, through a variety of rigorous scientific examination and testing, the use of safe and reliable. The large diameter of pipes, transmission efficiency, and can save the laying of pipeline investments. Mainly used to transport oil, natural gas pipeline. 2, the pressurized fluid transport with spiral seam high frequency welded steel pipe (SY5038-83) in the hot-rolled steel strip coils for the tube, often warm spiral shape, using high-frequency lap welding method welding for pressure transmission fluid spiral seam high frequency welded steel pipe. Pressure steel capacity, good plasticity, easy welding and machining molding; through a variety of strict and scientific examination and testing, the use of safe and reliable, large diameter steel pipes, transmission efficiency, and saves the laying of pipeline investments. Mainly used for laying a pipeline to transport oil, natural gas, etc..
