Manufacturers of Stainless Steel Pipes in China - Verified Factories

China is a world leader in the production of stainless steel tubes and is the main supplier for the oil and gas, energy, chemical, and construction industries. Finding a reliable stainless steel manufacturer in China can be challenging due to the vast number of market offerings. The China Global Hub platform conducts independent factory inspections to identify the best suppliers and award them the Verified by China Global Hub mark. This allows international companies to confidently work with verified manufacturers and minimize risks.

For several decades, China has maintained the status of a world leader in the production of stainless steel and pipe rolling. The country supplies a significant portion of the global market, providing products for the energy, petrochemical, mechanical engineering, construction, food, and pharmaceutical industries.

However, it is often difficult for foreign companies to find a reliable manufacturer of stainless steel tubes in China. The internet is filled with hundreds of offers, and it can be difficult to verify the actual capacity and quality level. Therefore, we are launching a series of inspections of enterprises and awarding the Verified by China Global Hub quality mark to help foreign partners navigate the market.

Our mission on the China Global Hub platform is based on three principles:

1. In-house factory verification – we visit production lines, evaluate technologies, and monitor quality processes.

2. Comparison to international standards – ASTM, DIN, ISO, PED, API; we consider export experience and technical innovations.

3. Formation of a list of reliable suppliers – verified factories receive a quality mark confirming their reliability for international clients.

This approach minimizes risks for buyers and helps Chinese companies stand out against competitors.

Our first review was dedicated to Sinosteel Stainless Steel Pipe Technology (Shanxi) Co., Ltd. – a modern factory in Shanxi province, exemplifying the combination of technologies, quality, and international experience.

The plant produces seamless and welded stainless steel pipes for the domestic market and export. The main products are used in the oil and gas industry, energy, chemical engineering, as well as in infrastructure projects where durability and resistance to aggressive conditions are critical.

• Modern production lines allow the manufacturing of pipes with various diameters and wall thicknesses, including non-standard sizes tailored to customer needs.

• Process automation ensures quality stability and defect minimization.

• All products are certified to ASTM, DIN and ISO, ensuring compliance with the requirements of leading international customers.

• The plant is ready for certification to additional standards for specific markets, including PED and API.

• Pipes are resistant to high temperatures, pressure, corrosion, and aggressive chemical environments.

• They are ideal for projects with stringent operational requirements, such as in the oil and gas industry and energy sector.

• Sinosteel actively supplies products to Europe, Asia, and the Middle East.

• The plant has experience with large contracts, including comprehensive document support and customs assistance.

• The expert team highlights the high level of R&D, readiness to introduce new alloys and technologies.

• The plant is focused on long-term contracts and supporting partners at all delivery stages.

Expert Assessment: Sinosteel demonstrates a mature approach to quality, innovation, and readiness for global cooperation, making it one of the leaders in the stainless steel tube market in China.

To create a complete picture of the industry, inspections are planned:

• Zhejiang Jiuli Hi-Tech Metals Co., Ltd. (JIULI) – stainless and special alloy tubes for oil and gas.

• TISCO (Taiyuan Iron & Steel) – a wide range of stainless steel and pipes.

• Baosteel / Baowu Group – a metallurgical giant with global supplies.

• Tsingshan Holding Group – a leader in stainless steel production with plants in different countries.

• Foshan Vinmay Stainless Steel – welded pipes for the food and construction industries.

• Huashang Steel (Wenzhou) – pipes and fittings with export to Europe, USA, and the Middle East.

All factories are assessed using the same criteria: automation level, quality standards, export policy, and readiness for long-term cooperation.

Companies value not only price but also:
✅ product quality;
✅ supply stability;
✅ transparency of document flow;
✅ compliance with international requirements.

Inspections allow the formation of a “golden list” of manufacturers who can use the Verified by China Global Hub quality mark.

For Chinese manufacturers, participation in the project is an opportunity:

• to confirm a high level and enter new markets;

• to strengthen their reputation among foreign clients;

• to gain a competitive advantage over non-verified factories.

For international buyers, it’s a guarantee of working with verified factories.

Our first visit showed that Sinosteel Stainless Steel Pipe Technology meets high international standards. Upcoming inspections will reveal industry leaders and create a comprehensive “golden list” of verified manufacturers.
