What is Rotary shouldered connection?
A connection used on drill string elements which has coarse, tapered threads and sealing shoulders.
What is PAC connection?
PAC ( Pacific Asia Connection ) is a non preferred special connection for drill pipes with smaller diameter, shorter threads and a longer connection. PAC drill pipes are typically used in smaller well holes drilling, repair, and fishing operations.
What is an API thread?
API Thread Gauges All drilled wells for oil and gas production require casings to provide sufficient strength and functionality. The American Petroleum Institute (API) recognizes 3 basic types of joint connections: Long and short Couplings with rounded thread. Couplings with asymmetrical trapezoidal buttress threads.
What is internal flush thread?
A type of tubing connection in which the internal or external surfaces are the same diameter throughout the tubing joint. Internal flush joints are most common, offering no restriction to fluid flow.
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 bevel diameter?
The outer diameter of the contact face of the rotary shouldered connection.
Are API and NPT threads the same?
This may be a bit late for your requirements, but here goes: in my experience many engineers equate API (line pipe threads) & NPT as one and the same. They are not. The API standard (from memory) highlights a few variations on the taper length, which would not be compatible with a standard NPT dimension.
What is an API coupling?
API petroleum couplings are designed for use in petroleum tanker loading. They provide safe, dry connection between the bottom loading arm and the petroleum road tanker, enabling product to be safely loaded. They are used in all petroleum tanker bottom loading applications.
What is Reg thread?
REG(Regular Style Connection) This type of drill pipe joint thread was used to connect the inner upset drill pipe so that drill pipe diameter is smaller than the inner diameter of the thickened and the inner diameter of the thickened is smaller than the diameter of the inner tube diameter.
What is a box thread?
Internal (female) threads of a rotary shouldered connection.
What is API 17D?
Description / Abstract: API SPEC 17D, 3rd Edition, October 2021 – Specification for Subsea Wellhead and Tree Equipment. This document provides specifications for subsea wellheads, mudline wellheads, drill-through mudline wellheads, and both vertical and horizontal subsea trees.
What is difference between casing and tubing?
Tubing naturally has a smaller diameter than casing, except for the 4 1/2-inch diameter. Anything smaller is called tubing, anything larger is casing. From the surface to the bottom of the well, the casing telescopes down in size – there are various types of casing depending on their purpose and diameter.
Is the API 7-2 specification applicable to rotary shouldered connections?
Normally, each API 7-2 specification is completely applicable to various rotary shouldered connections. However, while incredibly flexible, an API 7-2 specification should maintain usage over several preferred connection designs. Several popular styles are listed below:
Who are the manufacturers of Rotary shouldered connections?

What do you need to know about API 7-2?
The API 7-2 specification handles rotary shouldered connections, and outlines required inclusions utilized in natural gas and petroleum industries. Where the API 7-2specification is used, many dimensional requirements are adhered to—guaranteeing quality fit and an appropriate application, regardless of thread or thread gauge.
