Product Introduction
Product Overview — API 5CT 2-7/8" (73mm) Seamless Tubing
Our 2-7/8 inch (OD 73.03 mm) pipe is manufactured in strict compliance with API 5CT / ISO 11960 and API 5B standards. As the smallest standard OCTG size in this range, it is widely used as tubing (production string), small-diameter casing, and liner for shallow to medium-depth wells (up to 3,000 meters), as well as injection wells, gas wells and geothermal wells.
