API Thread Gauges are used for gaging API internal & external threads, manufactured according to API 5B, API 7-2 & API 11B standard, including working gages and master gages.
API working thread gauges include plug gauge and ring gauge. All of our working gauges will be inspected by master gauges after production and corresponding Calibration Certificate will be provided together with thread gauges or separately couriered as clients’ request.
Our thread gauges are mostly used to inspect thread of tubing, casing, drill pipe, drill collar, line pipe, sucker rod & polished rod, etc.
The thread type includes: EUE/UPTBG, NUE/TBG, BTC/BCSG, STC/CSG, LTC/LCSG, REG, IF, FH, NC, LP, NPT, etc.
Size Range: 2-3/8 ~ 20 in
Thread: BTC, STC, LTC, EUE, NUE, NC, IF, FH, REG, PH-6, XT, HT-PAC, etc.
Type: Heavy Duty or light
Material: HDPE, steel, steel-plastic
Application: To protect the thread and connection of casing, tubing, drill pipe during transportation and loading and unloading
