API SPEC7-2-2017 pdf download.Threading and Gauging of Rotary Shouldered Connections.
1 Coverage 1 .1 This standard specifies the following requirements on rotary shouldered connections for use in petroleum and natural gas industries: dimensional requirements on threads and thread gauges , stipulations on gauging practice and gauge specifications , as well as instruments and methods for inspection of thread connections. These connections are intended primarily for use in drill-string components. Other supplementary specifications can be agreed between interested for special tolerance requirements , qualification , testing , inspection , and finishing. This standard applies both to newly manufactured connections and connections that are recut after service. It should be realized that recut connections are subject to additional inspection and testing- the user is re1erred to API 7G -2 for such in1 0rmation. This standard is applicable to the following preferred rotary shouldered connection designs. These are traceable to an internationally supported system of gauges and calibration that can be described as number (NC) style , regular (REG) style , or full-hole (FH) style. Application of the API Monogram 1 .2 If the product (gauge) is manu1 actured at a facility licensed by API and , it is intended to be supplied bearing the API Monogram , the requirements of Annex A apply Normative References 2 The 101 10wing referenced documents are indispensable 10r the application 01 this documen t. For dated references , only the edition cited applies. F or undated references , the latest edition of the referenced document (including any amendments) applies.

NOTE The number rela les 10 a h isto r ical drill pipe size. 3.1 .1 0 gauge point Imaginary plane , perpendicular to the thread axis of rotary shouldered connections at which , C , the pitch diameter at gauge point is measured. NOTE This plane is located 15.875 mm (0.625 in.) from the makeup shoulder of the pin or box connection (pi n or box end) , except on Working plug gauges , where it is located 34.925 mm (1.375 in .) from the reference face.
3.1.11 GOST Z style Type and size of the rotary shouldered connection , covered by a Russian standard , having the V-038R , V- 040 , or V-050 thread form. The number designation is the pin-base diameter , rounded to units 01 mil li meters. NOTE 3.1 .1 2 H90 style Type and size of rotary shouldered connection , having a 90 0 thread (90-V-050) form. The number relates to a historical drill pipe size .
