In addition, you find our seamless mechanical steel tubing for industrial applications ranging from bearings to cylinders and gears where toughness is essential for functionality. Oil and gas exploration is another common use for our seamless mechanical tubing, where durability and component life below the Earths surface is paramount. Cylinder tube Manufacturers & Suppliers, China cylinder Cold Drawing Seamless 316L Cylinder Pipe Hardwave Stainless Steel Tube. PPGI , Seamless Steel Pipe , Galvanized Steel Coil , Stainless Steel Plate Mgmt. Certification:ISO 9001, ISO 9000, ISO 14001, ISO 10012 Carbon Oil Gas Steel Pipe/Tube Price List Difference between Seamless and Welded Tube & Pipe To control outside diameter and wall thickness, seamless type dimension is difficult to control compared to welded tube, cold work improves the mechanical properties and tolerances. Cold pilgering is the preferred production process since this technique provides a high forming rate, narrow tolerances and good productivity yields, but cold drawing gives narrower tolerance ranges and better surface quality.
