Api tubing coupling of various grade

API external upset end tubing Coupling is the joining of two short length pipes by the means of male and female threads. All types of tubing Coupling have internal threads which are known as female thread forms. These thread forms are usually machined so that they can be coupled with the external threads on pipes known as male thread forms.

Engineering offers a wide variety Couplings for Casing, Tubings and Line Pipes. The Tubing / Casing and Line Pipe Couplings are manufactured to meet the requirements of API 5CT and API 5L certifications respectively.

·All Coupling Stock is certified to API Standards by an independent 3rd party laboratory prior to coupling manufacturing.

·After machining all couplings undergo 100% thread inspection.

·Colour Coding and Marking as per API Standard

·MTRs available for all coupling

·Special Clearance Buttress Casing Couplings up to 10-3/4” are available on request.

·Slip on Couplings available on request.

·The manufacturing of certain Sizes and Grades of large diameter tubing Coupling are subject to the availability of raw material.

· Certain proprietary threads available upon request. Additional information such as End User and location maybe required by OEM prior to approval.
