IS 1239 YST 240/ 210/ 310/ 355 ERW Pipes manufacturer in china

Steel tubes produced under Indian standard 1239 is to be constructed either in a seamless or welded manner. Seamless carbon steel IS 1239 YST 240 has to be produced from tested quality steel, which in turn is to manufactured by any process that has been approved. This carbon steel grade is to be fully killed. Welded IS 1239 ERW Pipe can be made from hot-rolled steel strip or from Cold-rolled low carbon steel sheets and strips.

If manufactured from hot-rolled steel strip, the process needs to conform to the Indian standard  IS 10748. And if Cold-rolling is used in the manufacture of these steel sheets and strips, they must conform to IS 5I3. The construction of seamless IS 1239 YST 210 / 240 / 310 / 355 Pipes with the use of any one of the following processes i.e. Hot-finished or Cold-finished processes. On the other hand, welded tubes could be constructed by use of a Hot-finished welding process or an Electric resistance welding process or lastly, a high-frequency induction welding process. Carbon steel IS 1239 YST 210/355 Pipes are well suited to all of the above welding processes. However, this being said, it is important to note that a welded pipe produced from any material would be able to function well in about 20% reduced pressure in comparison to a seamless pipe of the same material. This carbon based IS 1239 YST 310 Mild Steel Pipe is proposed for application for non-hazardous gas, air and steam as well as the conveyance of water. The size range for IS 1239 Carbon Steel Pipe according to this standard ranges between a nominal bore size 6 mm to a nominal bore size 150 mm. Usually, medium and heavy IS 1239 Steel Tubes are approved for applications involved moving only steam.
