Tubes China

What Tubes China does

Tubes China (legally Zhangjiagang Changna Tube Industry Co., Ltd. / 张家港长纳管业有限责任公司) is a privately held Chinese industrial pipe and steel tube manufacturer and trader founded in 2006 and headquartered in Zhangjiagang, Jiangsu Province. The company positions itself as a 'one-stop tubes supermarket', offering CNG gas cylinder tubes, seamless steel pipes, honed tubes, hydraulic props tubes, high-pressure boiler tubes, nuclear power tubes, and oil country tubular goods (OCTG) such as T95 TP-CQ special buckle casing and TP-JC serrated thread oil pipes. Production-scale output is enabled through an associated relationship with Tianjin Pipe Group Corporation (TPCO), with reported milestones of 142,000 tons of finished pipes in a single month and 260,000 tons of monthly steel output at affiliated facilities, alongside a TECH-NIP submarine line pipe certification.

The firm operates a B2B direct-sales model, reaching enterprise customers via email and phone inquiries, international trade show participation (notably Tube & Wire Dusseldorf 2016), and a bilingual website that doubles as an industry knowledge hub aggregating 5,078 trade news articles. Named enterprise customers include China General Nuclear Power Group (CGN) under a 140 million yuan nuclear power tube contract for the Guangdong Yangjiang nuclear power plant, Beijing State Power FuTong Technology Development Co., Ltd., and Mid-East Petroleum Corporation for long-term OCTG supply. Pricing is not publicly disclosed; quotes are issued on inquiry, consistent with project-based industrial procurement rather than standardized catalog sales. Strategic partnerships with TAHEC (since October 2013) and the TPCO affiliation underpin both product breadth and export reach into the Middle East, Armenia, and European markets.

Revenue mechanics are anchored in one-time, project-driven B2B contracts for specialized tubular goods rather than recurring software-like streams; the firm explicitly operates a manufacturing/export revenue stream with no subscription or licensing components. Customer mix is concentrated in heavy industry verticals — oil & gas, mining, power generation, and nuclear power — where procurement is lumpy and certification-dependent. With 1-10 in-house employees, a 2017-vintage website, and no disclosed funding rounds, the trading entity appears to function as a sales and export interface, with physical production executed largely through the TPCO affiliate network.
