API Specification 5CT, 10th Edition. We are pleased to announce the publications of the 10 th edition of Specification 5CT, Casing and Tubing, and the 7 th edition of Technical Report 5C3, Calculating Performance Properties of Pipe Used as Casing or Tubing. These new editions provide technical updates that have reached consensus within APIs Subcommittee on Tubular Goods and will now give ASTM Hardness Standards Reference Guide29 rows · C661. Standard Test Method for Indentation Hardness of Elastomeric-type Sealants by Age-Hardened Nickel-Based Alloys for Oil and Gas 2 API STANDARD 6A718 Age-Hardened Nickel-Based Alloys for Oil and Gas Drilling and Production Equipment Upstream Segment API STANDARD 6A718 THIRD EDITION, DATE FOREWORD This Standard for Age-Hardened Nickel-Based Alloys was formulated by the API Exploration and Production
correct, thus API Spec 6A does require hydrostatic seat testing (extended) for all PSL 3G rated valves. Spec 6A 19th Table 7 Table 7 of API 6A, 19th Edition, implies that Charpy impact specimens of sizes 6.7 x 10 mm and 3.3 x 10 mm (ASTM A370 standard sub- sizes) are not permitted. Holly A. HopkinsMar 16, 2017 · establish maximum hardness for bolting material.)Objective is to identify hardness and associated yield limit to prevent HISC in subsea fasteners. API 20E BSL-2 Continuous Cast and BSL-3 Bolts 5 Yield strength/hardness levels/ (105ksi/28HRC, 120ksi/30 HRC, 135ksi/32 HRC, and 150 ksi/35HRC, and 165ksi/38 HRC) Minimum Hardness according to NACE and API 6A - Metal Apr 13, 2010 · For example, an API 75k material designation has a 95ksi tensile requirement. So your minimum hardness would be about 197 BHN and you max would be aboud 235 BHN (= 250 HV or 22 HRc). API doesn't get into hardness for austenitics, but you should be able to find them in an ASTM spec. try ASTM A182 for forgings.
Comparison of Valve Standards API 6D vs API 608 12 API 6D INDEX API 6D 24TH EDITION, AUGUST 2014 API 608, 4TH EDITION, DECEMBER 2008 Description Sec Description Sec Scope This specification defines the requirements for the design, manufacturing, assembly, testing, and documentation of ball, check, gate, and plug valves Shore Hardness Test - Standards Search Engineering360Feb 01, 2012 · This standard specifies the hardness testing of rubber test pieces and products. The hardness of a rubber is determined by its viscoelastic properties, particularly the elastic modulus as determined in DIN 53504. Type A durometers are suitable for testing in the Supplementary Specification to API Standard 661 Air This specification is written as an overlay to API Standard 661(parent standard), following the clause structure of the parent standard, to assist in cross-referencing the requirements. Where clauses from the parent standard are not covered in this specification, there are no supplementary requirements or modifications to the respective clause.
HARDNESS. A hardness survey must be performed on one pipe per heat. If the wall thickness is >0.450, the survey consists of three rows of measurements; near the OD, Mid-Wall, and ID. Each row consists of three indentations. For thinner wall pipe, the survey may be limited to one or two rows, as described in API 5CRA figure B.4.
