Submerged arc welding spiral steel pipe
Jul 10, 2018 · Therefore, most of the smaller diameter welded pipes adopt straight seam welding, and the large diameter welded pipes mostly adopt spiral welding. Spiral pipe and its standard classification: spiral seam submerged arc welded steel pipe for pressure fluid transportation (SY5036-83) is mainly used to transport oil and natural gas pipelines; spiral seam high frequency welded steel pipe for pressure fluid transportation (SY5038-83), Spiral seam high-frequency welded steel pipe Submerged arc welding process of steel pipeChoosing the right flux and welding wire for a specific submerged arc welding process is very important to obtain good results. Although the submerged arc welding process itself is efficient, it can increase production efficiency based on the welding wire and flux used. The flux is not only effective in the welding Submerged arc welding pipe, SAW pipes, SAW pipe d seamless steel pipe used for Submerged arc weldingIn single seam SAW pipe, wedding is done with the help of submerged arc welding process. In this method, a welding arc is submerged in welding flux. A Continues solid filler wire is fed from the outside. The pipe is welded first inside and then from the outside.
