introduction
This specification reference to the following criteria drafted.
GB/T 22512.2-2008 petroleum and natural gas industries - Rotary drilling equipment - Part 2. rotary shouldered
Processing and measurement threaded connection
APISPEC5B2008年第 version 15 casing, tubing and line pipe threads, measuring and test specification
(SpecificationforThreading, Gauging, andThreadinspectionofCasing, Tubing, and
LinePipeThreads)
The specification for the revision, instead of JJF 1108-2003 "oil drilling connector thread work rules, work round thread casing
For gauge and tubing thread gauge calibration workload specification. "
The main amendments.
--- Increased workload buttress casing thread gauge calibration.
--- Increased workload line pipe thread gauge calibration.
--- Rotary shouldered connections Thread Work Gauge big trail parameters, according to GB/T 22512.2-2008 standard
Quasi been revised.
--- Calibration method of presentation has been revised. Calibration method based on coordinate measuring principle, gives the corresponding
Formula.
--- Reference to GB/T 22512.2 and Thread Work Gauge APISPEC5B use "metering performance requirements"
Moved to Appendix A, B, C in.
Oil thread gauge calibration workload specification
1 Scope
This specification applies to the calibration of rotary shouldered connection thread work regulation, as well as a round thread casing, buttress sleeve
Pipe, tubing, line pipe thread gauge calibration workload.

3.1 truncated threadheighttruncated
In the direction perpendicular to the axis of the thread from the thread type from the original vertices of the triangle to the top of the thread profile.
4 Overview
Oil thread (OCTG) are OCTG (oilcountrytubulargoods) threads for short.
According to the close relationship between the transfer from the threaded proofread gauge for determining thread Work Gauge interchange standoff value, thread
Direct to check product compliance workload threads. Thread Work Gauge work includes a threaded plug gauge and thread ring gauges work. screw
Working within the grain product inspection plug thread, thread ring gauge to check the work product external threads.
Depending on the form of thread products, using different thread work rules.
Rotary shouldered threaded connection preferred thread gauge can be divided according to their type of digital type (NC), normal form
(REG), consistent eye type (FH) and the inner flat (IF). Press into right-handed and left-handed rotation.
Casing thread gauge thread is divided according to type round thread casing thread gauge (CSG) and buttress casing screw
Grain gauge (BCSG).
Pipe thread gauge form of the structure is divided into non-upset tubing thread gauge (TBG) and external upset thread gauge
(UPTBG).
Line pipe thread gauge marked. LP.
