Page 3 of 7



B.

6

The plants or facilities as well as the Quality Control and Quality Assurance Programs of both the manufacturer and the sub-contractor shall be approved by Saudi Aramco Inspection Department (SAID). However, the SAID Survey Reports have to be approved by the RSA in order to include that manufacturer in The Approved List of Manufacturers.

Required Specification 6.1

Anti-Galling Plating For API 8RD or Buttress connections, the threads of both pin and box shall have either Zinc or Phosphate plating. For Premium Connections, the anti-galling plating shall be applied on both pin and box threads. However, the plating type shall be to the patent holder's specification.

6.2

Hydrostatic Pressure Rating For API 8RD or Buttress threaded and coupled connections, the hydrostatic pressure test shall be performed in accordance with API SPEC 5CT with the couplings installed power tight with API Modified Thread Compound with friction correction factor of 1.0 in accordance with API BULL 5A2. For Premium Grades and Premium Connections, the hydrostatic pressure test shall be conducted in accordance with the manufacturers pressure ratings specification with the couplings installed power tight with API Modified Thread Compound with Friction Correction Factor of 1.0 in accordance with API BULL 5A2.

6.3

Thread Storage Compound Prior to shipping, both the pin and the box threads shall be covered with a Saudi Aramco approved anti-corrosive storage compound such a Kendall Kendex, Driltec Thred Protec, and Jet Marine Imperator 2571. If manufacturers want to use any others, technical specifications shall be submitted to the RSA for technical evaluation and approval.

6.4

Thread Protectors For 4-½ inch and smaller sizes with API Connections, and all sizes with Premium Connections, anti-corrosive thread storage compound shall be applied on the threads and thread protectors shall be installed immediately after final inspection.

Page 4 of 7



Both box and pin protectors shall be heavy duty polyethylene elastomer Drilltec type resistant to ultraviolet radiation and with the size and thread type permanently marked either by die stamping or embossing. The box end shall be closed ended non-liftable and the pin end shall be open ended. For 7 inch and larger sizes with either API 8RD or Buttress Connections, anticorrosive thread storage compound shall be applied on the threads and thread protectors shall be installed immediately after final inspection. Protectors shall be heavy duty mill standard steel thread protectors, Drilltec steel encapsulated polyethylene type or Drilltec composite type resistant to ultraviolet radiation and with size and thread type permanently marked on the protector. The box end shall be closed ended non-liftable and the pin end shall be open ended. All thread protectors that will be used by the manufacturers as an equivalent to Drilltec shall be approved by the RSA. 6.5

API Markings For API Grades and API Connections, all API markings shall be both paint stenciled and low stress die stamped in accordance with API SPEC 5CT, Section 10. For Premium Grades or Premium Connections, all markings usually required by API shall be both paint stenciled and low stress dye stamped in accordance with API SPEC 5CT, Section 10 except that API Monogram is not required.
