What Tianjin TianGang Special Petroleum Pipe Manufacture Co., LTD does

Tianjin TianGang Special Petroleum Pipe Manufacture Co., LTD (天钢石油) is a privately-held Chinese manufacturer of high-end petroleum Oil Country Tubular Goods (OCTG), founded in 1997 and headquartered in Tianjin Jinnan Economic Development Zone. The company operates with 300+ employees across more than 200 mu (approximately 33 acres) of land, running two wholly-owned subsidiaries — Tianjin Meijin Steel Pipe Co., Ltd. and Tianjin Binhai Tiancheng Petroleum Drilling Equipment Co., Ltd. — that provide vertical integration into steel pipe manufacturing and petroleum drilling equipment. Its stated annual production capacity is 300,000 tons of casing and tubing and 2 million couplings, with customers served across domestic Chinese oilfields (Northeast, North, Central Plains, Northwest) and more than 50 export markets spanning Europe, Americas, Africa, Middle East, and Southeast Asia.

The company's product portfolio spans three layers: (1) API 5CT standard casing and tubing across multiple steel grades (H, J, K, C, P, Q, T, L80-13Cr, P110SS); (2) proprietary special thread connection series (TG-QMI and TTSP-1 through TTSP-5) with differentiated sealing architectures (cone-to-cone metal seal, reverse torque shoulder, hook-type load-bearing threads) for high-pressure and complex well conditions; and (3) a complete screen pipe line — laser/CNC slotted, composite, wire-wrapped, bridge-type, and drilled screens — with proprietary nickel-based ceramic anti-corrosion coating and subcritical quenching heat treatment (27MnCrV) achieving yield strength of 820-860 MPa. The company has held continuous API 5CT certification since 2004 and holds first-tier network supplier qualification with both CNPC and Sinopec.

The business model is direct B2B hardware sales to oil and gas operators, with both domestic and international sales teams. Domestic revenue flows primarily through CNPC and Sinopec procurement networks; international revenue flows through direct export sales channels managed by the company's export team ([email protected]). Products are manufactured to order based on customer specifications. Pricing is not publicly disclosed. The company is privately held with no disclosed funding rounds, no public listing, and no institutional investors identified in the available sources.
