Description
The OCTG pipe thread gauge,as a measuring tool including plug gage and ring gage.The thread gauge is used to measure whether various parameters of the thread comply with API SPEC 5B, API SPEC 7-2, or ASME standards. The thread parameters include pitch, taper, flank angle, and pitch diameter.
The thread gage can be used for various thread such as ASME or ANSI thread gage such as TPI,NPT,NPSM,LP,STUB ACME 2G,UN-2A,BUTT-2A;and API 7-2 standard thread gage such as FH,H90,NC,PAC,REG;and API 5B standard gauge such as BCSG,LCSG,SCSG,EUE,NUE and premium thread gauge such as BGT3,BGT2,BGT2C,BG-FJ,BG-FJU,HSM2,HSM2C,TPCQ,TP-JC,BJC,XT39,XT54,HLST,HLIST,GPDS55,HYDRIL CS,PH4,PH6,JFE BEAR,JFE TIGER,OTTM,OTTG etc.
We can provide various measuring tools, such as Metric, American, British,Japanese,German,metric,control, square thread, R-thread, serrated, trapezoidal, gas cylinder,taper (NPT, Z, G, RC, RP, PT, ZG), sucker rod, Casing or tubing OCTG(TBG, UPTBG, CSG LTC,STC,BTC), drill rod, and premium thread for oil pump
The gauge must be cleaned with 120 # gasoline before use, and the thread surface must be visually inspected for scratches, burrs, or other foreign objects. The gauge should be cleaned and free of foreign objects before use.
When using a plug gauge or ring gauge for on-site thread inspection, hold the gauge by hand and slowly screw it in. When the gauge is close to the base surface, it should be turned back a few times to ensure that it is in a normal state before hand tightening. Avoid rapid rotation and withdrawal to avoid secondary surface damage caused by increased gap changes.
