Audited Supplier | Product Description |
| Stainless steel welded pipes, also known as welded tubing, are created by rolling stainless steel strips into tubes and welding them along their entire length. The weld seam can be left as is or refined using cold rolling and forging techniques. These metal pipes are used extensively in industrial settings for transporting liquids and gases, as well as in plumbing projects for conveying hot or cold water. |
| Working principle of stainless steel seamless pipes: |
| Stainless steel seamless pipes are produced by heating stainless steel billets to a certain temperature and then rolling them into shape using piercing or extrusion methods on seamless pipe mills. This method eliminates the need for welding and demands high precision in terms of inner and outer surface finish as well as dimensional accuracy. Stainless steel seamless pipes are widely used in high-pressure, ultra-high-pressure, chemical, and petroleum industries, as well as in mechanical structures requiring high dimensional precision. |
| Working principle of stainless steel welded pipes: |
| Stainless steel welded pipes are created by rolling stainless steel plates or strips into tubes and then welding them along their length. Welding methods may include high-frequency induction welding, resistance welding, or other welding techniques. Post-welding, the pipes may undergo cold rolling or forging to enhance their mechanical properties and relieve stress in the weld seam area. These pipes find applications in industries for transporting liquids and gases and in construction projects for piping systems. |
| Working Principle |
| The working principle of a stainless steel welded tube involves heating two steel pieces and joining them through welding, using a filler material to fuse the joint. Typically, these pipes are manufactured by roll-forming stainless steel strips or sheets into a tube shape and then welding them longitudinally along the pipe's length. This process can utilize either hot-forming or cold-forming techniques, with cold forming yielding smoother finishes and tighter tolerances. The welded seam can be left beaded or refined further using methods such as precision cold drawn seamless steel tubing. |
