What is EUE tubing?
The API external-upset-end (EUE) tubing connection is widely used because it is a good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strength greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.
What is API 5CT specification?
API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries.

What is thread limit gauge?
Thread Limit Gauge (LG): Ring Used to inspect male thread. The passing side and stopping side make up a single set. The thread is considered to be acceptable if the passing side passes with ease and the stopping side does not cut in after two rotations. This gauge is also used to inspect the whitworth screw.
What is standard thread gauge?
A standard thread gauge is a device used to measure the pitch, form, and threads’ depth. The indicator is also often applied to bolt holes to analyse the size of the hole. It will typically be an inexpensive tool used in the industry that will allow you to distinguish between different threads.
What is STC and LTC?
Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For casing pipe, most popular threading type is LTC (Long thread coupling), STC (Short thread coupling) and BTC (Buttress thread coupling).
What is API 5B?
API 5B specifies the thread element gauges, instruments, and requirements for API thread inspection. It also governs the dimensions, tolerances, and marking requirements for all API threads, including threads on Line Pipe, Round Thread Casing, Round Thread Tubing, and Buttress Casing connections.
What is API 5CRA?
API 5CRA serves as the leading industry standard for corrosion resistant alloy seamless pipe for casing, tubing, and coupling stock. It was first issued in 2010 and reaffirmed in 2015.
Do thread gauges need calibration?
There are many different types of threads to serve different purposes and many different threaded master gages to certify them. As with any reference standard, these threaded master gages need to be calibrated and certified to understand their critical parameters.
