Introduction to API 5B Thread Gauges and Sowant Precision Gage’s Capabilities

API 5B is a globally recognized standard for thread gauges used in oilfield tubular goods, ensuring precision and compatibility in casing, tubing, and line pipe connections. This article focuses on key thread gauge types under API 5B—LP (Line Pipe), CSG (Casing Short Round Thread), BCSG (Buttress Casing Thread), TBG (Tubing Round Thread), and UPTBG (Upset Tubing Thread)—with a detailed examination of the 4 1/2" CSG Plug Gauge and the comprehensive range of CSG thread gauges. Additionally, we highlight the expertise of Sowant Precision Gage Co., Ltd. in supplying high-quality measurement tools, including Mitutoyo products and specialized thread gauges.

API 5B Thread Gauges: Standards and Applications

1. CSG (Casing Short Round Thread)

   • 4 1/2" CSG Plug Gauge:

     • Specifications:

       • Outer Diameter: 114.3 mm

       • Pitch: 3.175 mm (8 threads per 25.4 mm)

       • Taper: 1:16

       • Thread Angle: 60° .

     • This gauge is critical for inspecting short-round casing threads, ensuring compliance with API 5B standards for sealing and mechanical strength.

   • Full Range of CSG Thread Gauges:
     CSG gauges cover sizes from 4 1/2" to 20", with standardized parameters across all dimensions (see table below) :

     Size (inches)	Outer Diameter (mm)	Pitch (mm)	Taper	Thread Angle
     4 1/2	114.3	3.175	1:16	60°
     5	127	3.175	1:16	60°
     5 1/2	139.7	3.175	1:16	60°
     6 5/8	168.28	3.175	1:16	60°
     ... (up to 20")	...	...	...	...

2. Other API 5B Thread Gauges :

   • LP (Line Pipe): Covers 1/8" to 12", used for pipeline connections.

   • BCSG (Buttress Casing): Designed for sizes 4 1/2" to 6", offering enhanced load-bearing capacity.

   • TBG/UPTBG (Tubing Threads): Applied to tubing connections (1.050" to 4 1/2"), with UPTBG featuring upset ends for higher pressure resistance.
