API THREAD GAUGE FOR THE OIL AND GAS INDUSTRY
Introduction of the API Thread Gauge
The API standard, issued by the American Petroleum Institute (API), specifies the threading, gauging, and testing requirements for threaded connections used in casing, tubing, and line pipe applications within the oil and gas industry. In addition, this standard ensures the strength and sealing integrity of threaded connections operating under high-pressure and high-stress environments. Moreover, high-precision API thread gauges play a critical role in improving product quality, ensuring operational safety, and extending equipment service life.
TYPES OF API THREAD GAUGES
Types of API 5B Standard Thread Gauges
TBG Type EUT Thread Gauge
Manufacturers use API UP TBG (EUT) thread gauges to inspect external upset tubing threads in accordance with API Specification 5B. In addition, the gauges provide high accuracy during thread manufacturing and assembly processes. Furthermore, users apply them to oilfield applications that require excellent sealing performance and durability.
TBG Type NUT Thread Gauge
Manufacturers design API TBG (NUT) thread gauges to inspect non-upset tubing threads according to API Specification 5B. In addition, the product ensures thread accuracy and supports reliable connection performance. Furthermore, users widely apply it in oilfield equipment manufacturing and maintenance.
CSG Thread Gauge
Manufacturers use CSG (Casing) thread gauges to inspect casing threads in compliance with API Specification 5B. In addition, these gauges help ensure thread sealing integrity and dimensional consistency during installation. Furthermore, users apply them to casing systems used in oil and gas drilling operations.
BCSG Thread Gauge
Manufacturers produce BCSG thread gauges according to API Specification 5B to inspect buttress casing threads. In addition, the gauges provide precise inspection capability and improve the reliability of heavy-duty threaded connections. Furthermore, users widely apply them in drilling and oilfield operations.
Manufacturers produce LINE PIPE thread gauges in accordance with API Specification 5B to inspect line pipe threads used in oil and gas transportation systems. In addition, the gauges help ensure thread compatibility and support leak-tight connections. Furthermore, users apply them to various industrial pipeline applications.
Types of API 7-2 standard thread gauges
NC Thread Gauge
Manufacturers produce NC thread gauges under API Specification 7-2 to inspect Numbered Connection threads for drilling equipment. These gauges deliver high inspection accuracy and maintain stable performance. They suit drill strings and related drilling tools.
REG Thread Gauge
Manufacturers design REG thread gauges according to API Specification 7-2 to inspect Regular Connection threads used in drilling equipment. The gauges help ensure thread accuracy and support reliable assembly performance. Users widely apply them in conventional oilfield drilling applications.
PAC Thread Gauge
Manufacturers produce PAC thread gauges under API Specification 7-2 to inspect PAC threads in drilling systems. The product delivers high precision and enables effective thread quality control. It suits applications that require excellent durability and sealing capability.
