We are pleased to introduce our full portfolio of seamless oil casing and production tubing manufactured in accordance with API 5CT standard, designed for onshore and offshore oil & gas well applications.

Our OCTG (Oil Country Tubular Goods) line covers a wide range of steel grades including N80, P110, L80, L80 9Cr and 13Cr, available with various thread connections such as EUE 8RD, NUE and premium special threads. Sizes from 2-3/8” up to 20” can be customized to match different well depth and reservoir conditions.

Oil casing is used to secure the wellbore, isolate different formations and prevent well collapse. Production tubing serves as the flow channel for crude oil, natural gas and injection media. For corrosive downhole environments, L80 9Cr and 13Cr grades deliver outstanding resistance to CO₂ and mild H₂S corrosion.

Every pipe undergoes a complete inspection procedure: chemical analysis, mechanical property test, hydrostatic pressure test, NDT non-destructive testing and thread dimensional inspection. Thread protectors and VCI anti-rust packaging are applied to safeguard pipe ends during sea transportation.

Our facility holds API 5CT and API Q1 certifications. Besides casing and tubing, we also supply matching downhole accessories including setting nipples, couplings and pup joints. We support both standard stock items and customized non-standard OCTG for global energy operators.
