DIN 1629 ST 37 Seamless Pipe 88.9mmx3.25mm 12m length
This particular grade of ST 37 Steel Grade Seamless Pipe 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 Carbon Steel ST37.0 p235tr1 Round Pipe is used in almost all sectors of various industries. Since variations are available in the types and sizes of the DIN 2448 ST 37 Rectangular Pipe, these pipes could also be used for general purposes.
The diameter of the DIN 1629 ST 37 Seamless Pipe ranges between 10,2 mm to about 219 mm with the wall thickness being up to 12.7 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
DIN 1629 include 3 basic steel grades (ST37, ST44, ST52.), this standard specifies the Seamless Circular Tubes of Non Alloys Steels that are used in construction of chemical plant, pressure vessels, pipe system and general mechanical and engineering purposes. The main steel grades are Din 1629 specification applies to seamless steel tubes and pipes are suitable for gas fusion welding, arc welding, flash butt welding, electric pressure welding and gas pressure welding. Seamless steel pipe, welded steel pipe, Galvanized steel pipe are all available.
The limits of application and other specifications given in this standard shall apply except in cases here other specifications are contained in codes of practice for specific fields of application, e.g. the Technische Regeln fur Dampfkessel (TRD) (Technical rules on steam boilers) or the Technische Regeln fur Druckbehalter (TRB) (Technical rules on pressure vessels), AD-Merkblatter (AD Instruction sheets).
