Large Diameter Longitudinal production process is simple, high production efficiency, low cost, and the strength of large diameter spiral welded pipe Longitudinal generally higher than, can narrow the billet production of large diameter pipe, you can also use the same width of the billet production of different pipe diameters, pipe rack, but the production efficiency compared with relatively low for pipe joints. Large diameter pipe used for large pipeline projects, water gas engineering, distribution network construction, municipal engineering, water supply and drainage works, construction of large steel structure, pile foundation and so on. The main testing methods of large diameter pipe to the main flaw detection. Using machine welding and manual welding method of combining.
