API is short for the American Petroleum Institute, API certification sub-system API monogram certification and product certification. The tubing pipe with API monogram certification is high quality.
API monogram licenses are only issued after an onsite audit by the API to verify that the licensee conforms to the requirements of API Q1 (QMS Requirements for Oil and Gas Industry), and that 5CT & 5L products are produced under the control of a Q1 quality management system.
Oil Tubing is pipe used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. Tubing is made to withstand the pressure generated from the extraction process. Tubing is manufactured in the same way as casing, except that an additional process known as “upsetting” is applied to thicken the pipes.
Tubing range of Sizes: 1.05”, 1.315”, 1.66”, 1.9”, 2 3/8”, 3 1/2” and 4 1/2”
Ends Type: BTC, UN, EUE, Premium ends that could completely replace the tubing premium connection of Vam, Tenaris, Hunting, JFE, etc.
Length of the Tubing in API 5CT Spec: R2, R3
OCTG Tubing in API 5CT mainly used to transport oil and gas well drilling and oil and gas. It includes oil drilling pipe, oil casing, pump tubing. Oil drill pipes are mainly used to connect drill collar and drill and pass drilling power. Oil casing is mainly used to support the borehole when drilling and after completion, to ensure that the conduct and completion of the drilling process after the normal operation of the entire oil wells. The pipeline mainly used in pumping oil and gas at the bottom transported to the ground.
