API Monogram Stamper/ Technician Follow the instruction given in Shop Order. Marking Requirement API Spec 6D

Valves that meet the requirement of ISO 14313 and API Spec 6D shall be marked in accordance with the requirements of Table 1 (Appendix B) and Table 2 (Appendix C). PTBMI API Monogram license number (6D-1322) is only being used and marked in conjunction with the API Monogram. 4.1

Marking Method a. Body/cover/closure stamping shall be performed using a low-stress die-stamp, rounded “V” or Dot Face type. b. Each valve shall be provided with an austenitic stainless steel nameplate securely affixed and so located that it is easily accessible. c. The marking on the nameplate shall be visually legible.

4.2

Identification Markings

On valves whose size or shape limits the body markings, they may be omitted in the following order: a. manufacturer's name or trademark; b. material; c. rating; d. size For valves smaller than DN 50 (NPS 2), the nameplate can be attached to the valve with the stainless steel wire. The nameplate and serial number may be omitted by client agreement. *NOTE: The purchaser can specify requirements for the marking of valve components.

If the valve with one seat uni-directional and one seat bi-directional, the directions of both seats shall be specified on a separate identification plate as illustrated in Appendix A: Figure 1. In Figure 1, one symbol indicates the bi-directional seat and the other symbol indicates the unidirectional seat. 4.3

API Monogram Record (API 6D)

Marking checklist for API 6D is being used to monitor the marking conformance as required by API product specification. This record shall be maintained for a minimum of 10 years. 5

Marking Requirement of API Spec 16A

Adapter and loose connections of API 16A manufactured in accordance with the American National Standard by PTBMI shall be marked in accordance with the procedure and requirements of API 16A and Table 3 (Appendix D), Table 4 (Appendix E), Table 5 (Appendix F), Table 6 (Appendix G), Table 7 (Appendix H), Table 8 (Appendix I). Equipment shall be stamped on the product with the product description code (PDC) or alphanumeric code, followed by “ISO 13533” or “API 16A” and PTBMI API 16A licence number (16A-0360). 5.1

Marking Method a. Low-stress-area marking Using of sharp “V” stamping for identification on low-stress areas (such as nameplate, outside diameter of flanges, etc.). b. High-stress-area marking Using of dot, vibration or round “V” stamping for identification on high-stress areas. Sharp “V” stamping is allowed in high-stress area only if subsequent stress-relieving is performed to the component.

c. Weld metal overlays When equipment has weld metal-overlaid ring grooves, the ring gasket type and number shall be followed by “CRA” to designate a corrosion-resistant alloy or “SST” to designate an austenitic stainless steel. Notes: a. All type 16B and 16BX hub connections shall be marked on the neck of the connection, 12mm (1/2 in) max from the required length of the neck. b. All flanges shall be marked in accordance with ISO 10423. c. If the ring groove is overlaid with corrosion-resistant material, the ring groove number shall be followed with “CRA”. 5.2

Repair and Remanufacture Markings

Location of marking for metallic equipment which is repaired or remanufactured shall be in accordance with Table 3 (Appendix D). The following marking shall be added to the parts: a. “RMFR” for remanufacture or “RPR” for repair. b. Repairer’s /remanufacturer’s name or mark. c. Date of repair or remanufacture (month & year). Note: For repair and/or remanufacturer marking requirement, the “RMFR” for remanufacture or “RPR” for repair shall be added adjacent to the API Monogram applied. 5.3

API Monogram Record (API 16A)

Marking checklist for API 16A is being used to monitor the marking conformance as required by API product specification. This record shall be maintained for a minimum of 10 years.
