Chemical composition of AP15L Hydrostatic pressure test:
The steel pipe shall be hydrostatically tested and shall have no leakage through the weld or pipe body.
The manufacturer should issue an inspection certificate complying with 5.1.B of GB/T18253-2000 or an inspection certificate complying with 3.1 of EN10204:2004. If the order contract stipulates another alternative method, the manufacturer shall issue an inspection certificate conforming to 5.1.A or 51.C of GB/T18253-2000, or an inspection certificate conforming to 3.2 of EN10204:2004 when applicable for each ordering batch The following information should be provided:
Specified outer diameter, specified wall thickness, steel pipe grade, PSL, steel pipe type and delivery status; chemical composition (melt analysis and product analysis) and carbon equivalent (product analysis and acceptance limits);
Tensile test results and specimen type, size, location and orientation;
CVN impact test results; specimen size, orientation and location: test temperature and acceptance limits applicable to specimens of specific sizes: welded pipe DWT test results (single test results and average test results);
Specify the minimum hydrostatic test pressure and specify the pressure stabilization time;
For welded pipes, the weld non-destructive testing method used (ray, ultrasonic or electromagnetic); the type and size of the reference reflector or image quality meter used. For seamless (SMLS) pipe, the non-destructive testing method used (ultrasonic, electromagnetic or magnetic particle). ); Type and size of reference reflector used For high frequency welded (HFW) pipe, the preferred temperature for weld heat treatment;
When applicable, proof that the butt-jointed steel pipes and/or flow pipes meet the requirements of Appendix A and/or Appendix 1: Name and location of equipment used for steel pipe manufacturing, steel strip (coil)/steel plate rolling and steelmaking, as specified in the order contract the results of any additional testing.
