The difference between spiral welded pipe and straight welded pipe

- Sep 30, 2019-

         Spiral welded pipes are widely used in building, bridge, road and other civil engineering construction.
Spiral welded pipe is widely used in natural gas, petroleum, chemical industry, electric power, thermal power, water supply and drainage, steam heating, penstock for hydropower station, thermal power, water and other long-distance transmission pipelines and piling, dredging, bridge, steel structure and other engineering fields.             

         The quality of spiral welded pipe is thin and low, and the phenomenon of filling is often unsatisfactory. The reason is that in order to achieve a large negative tolerance, the manufacturer has a large pressure in front of the finished product, a small iron profile and a unsatisfactory pass filling.

          There are many kinds of welded pipes. What kinds are they? Here's a brief explanation, so that you can understand what belongs to welded pipe, learn some knowledge outside stainless steel welded pipe.
The types of welded pipes are as follows:
         Longitudinal welded steel pipe: Its weld is parallel to the longitudinal of steel pipe, including welded thin-walled pipe, transformer cooling oil pipe, etc.
          Spiral submerged arc welded steel pipe for pressure fluid transportation: billet is hot rolled steel strip coil, then spiral forming, welding is double-sided submerged arc welding, mainly used to transport oil, natural gas and so on.
          High frequency spiral seam welded steel pipe for pressure fluid transportation: billet is hot rolled steel strip coil, then spiral forming, welding is using high frequency lap welding method.
          Generally, the spiral submerged arc welded steel pipe for low pressure fluid conveying is hot rolled steel strip coil, then spiral forming. The welding adopts double-sided automatic submerged arc welding or single-sided welding, mainly used for conveying water, gas, air and steam, etc.
         Generally, high frequency spiral seam welded steel pipes for low pressure fluid transportation are hot rolled steel strip coil, then spiral forming, and high frequency lap welding is used for welding.
Spiral welded steel pipe for pile: billet is hot rolled steel strip coil, then spiral forming, welding is double-sided submerged arc welding or high frequency welding.
