DIN 2391 ST 37 Steel Pipe
This particular grade of DIN 2448 ST 37 Seamless Steel Tubes is meant to be used for pressure as well as thermal purposes. This carbon steel grade line ST37.0 DIN 1629 Hydraulic Pipe has good properties at a specified room temperature. The DIN 2448 Seamless Steel Tubes is used in almost all sectors of various industries. Since variations are available in the types and sizes of the DIN 2448 ST 52 Pipe, these Rectangular pipes could also be used for general purposes. This carbon steel specified Din 2448 ST52.3 steel pipe could be manufactured in our factory either through the hot rolling process or it could be made through cold drawing.
The DIN 2391 ST37 Welded Pipe has been manufactured and is available with the diameters ranging between 213 to about 660 mm. On the other hand, the wall thickness of the DIN 2391 ST 37 carbon steel pipe ranges up to 100 mm in the case of hot rolling. While the diameters of the DIN 1629 ST 37 Seamless Pipe ranges between 10,2 mm to about 108 mm with the wall thickness being up to 12,5 mm in the case of cold drawn pipes. In order to check the tightness of the DIN 2391 ST 37 Steel Pipe, this steel grade needs to be subject to water testing at 7 Mpa. Alternatively, the DIN 2448 ST 37 could also be subjected to electromagnetic testing as well if tightness is to be checked.
