M-CR-630, Rev. 1, December 1994 page 1 NORSOK STANDARD COMMON REQUIREMENTS MATERIAL DATA SHEETS FOR PIPING M-CR-630 Rev. 1, December 1994 Please note that whilst every effort has been made to en sure the accuracy of the NORS OK standards neither OLF nor TBL or any of their members will a ssume liability for any use thereof. 1 FOREWORD This standard has been developed by the NORSOK standardisation work group and agreed by the Norwegian industry for the widest possible national and international application. Note: Materials of Type 6Mo and 25 Cr duplex manufactured prior to 01.01.95 can be accepted provided the following is satisfied: – Corrosion tests have been carried out with acceptance criteria fo r pitting and weight loss according to NORSOK MDS™es at 40 C. – The microstructure is free from all grai n boundary carbides and intermetallic phases. 2 SCOPE This Standard is a collection of the Piping Material Data Sheets (MDS) applicable to selected material standards and grades for use in piping systems. The scope for the MDS’s is as follows: The materials shall be delivered in accordance with the standard referred to. In addition the MDS specifies the selected options in the referred standard and additional requirements which shall be added or supersede the corresponding requirements in the referred standard. 3 NORMATIVE REFERENCES As stated in the indi vidual data sheets.
