Seamless Pipe DIN1629

This standard applies to seamless circular tubes and pipes(hereinafter briefly referred to as "tubes") made of unalloyed steels. These tubes are predominantly used in the construction of chemical plant, vessels, pipework and for general mechanical engineering purposes. They are designed to meet high performance requirements. Normally there are no limiting vaiues or the maximum permissible working pressure of these tubes. The permission working temperature shall not exceed 300℃
 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 Instrucation sheets).
 The standard designation for tubes complying with this standard shall give in the following order:
 - the term "tube";
 - DIN number of dimensional standard (DIN 1629);
 - characteristic dimensions of tube (outside diameter X wall thickness);
 - number of DIN Standard giving the for the steel grade
 - where applicable, the code letter N where the tuves are to be
 Tubes complying with this standard shall be manufactured by hot or cold rolling, hot pressing or hot and cold drawing
 Tubes manufactured by hot forming shall be supplied in the hot formed condition. In order to comply with the requirements regarding mechanical and technological properties the tubes shall, if necessary, be normalized. Cold rolled or cold drawn tubes shall be normalized after forming and supplied in this condition.
 The tubes shall have a smooth outside and inside surface consistent with the manufacturing process used.
 If the surfaces of the tubes are to be provided with an anti-corrosive agent with a limited life, this shall be agreed at the time of ordering. If special requirements are made on the tube (e.g. with regard to galvanizing, chromium plating ), this shall be agreed at the time of ordering.
