DIN 1630 carbon steel pipe is a high-precision steel pipe material. Its preparation methods include hot rolling or cold rolling, hot extrusion or cold drawing. It is mainly used for hydraulic system piping and automobile manufacturing piping.
DIN 1630 seamless carbon steel pipes include ST35 (E235), ST37.4, ST45 (E255), ST52 (E355), etc. The main delivery states are NBK (+N), GBK (+A), BK (+C), BKW (+LC), BKS (+SR), etc.
GNEE's DIN 1630 precision steel pipes have no oxide layer on the inner and outer walls, can withstand high pressure without leakage, and have the characteristics of high precision, high finish, no deformation during cold bending, and no cracks during expansion and flattening.
