Within the quarter, the team from Henyang Valin Steel Tube Co., Ltd. (HYST) visited our office to explore opportunities for partnership in the OCTG (Oil Country Tubular Goods) space.
HYST is a leading global manufacturer of seamless steel tubes and pipes. Established in 1958 as a subsidiary of Hunan Valin Iron & Steel Group Co., Ltd., HYST has grown over the decades into one of the world’s largest and most integrated producers in its field. The company currently boasts total assets of approximately 13.5 billion Yuan and a workforce of around 3,900 employees. HYST is accredited as a “high and new technology enterprise,” recognised nationally for its strong intellectual property rights portfolio, and is regarded among the top ten enterprises in export business and among the top ten demonstration units in safety in Hunan Province.
HYST is distinguished by its full vertical integration: it controls the complete production chain from iron-making to steel-making to tube rolling and further processing, enabling full control over quality and consistency. Their annual capacity is impressive: up to 1.1 million tons of iron, 1.7 million tons of steel, and 1.5 million tons of tubes. In addition, heat treatment of 830,000 tons of tubes and threading of 600,000 tons per year are among their milling capabilities.
As a special-steel tubes manufacturer, HYST offers seamless steel tubes and pipes over a broad specification range: outer diameters (OD) from 24 mm up to 800 mm, and wall thicknesses (WT) from 3.5 mm to 200 mm. They have established three major product lines:
- Petroleum & Natural Gas Tubes (OCTG / line pipe)
- Pressure Vessel Tubes
- Mechanical Processing Tubes
Additionally, they produce an in-house “HS series” built on their proprietary intellectual property rights.
Within China, it ranks among the leading producers, with comprehensive manufacturing plants, advanced equipment, and one of the most complete product specification ranges in the industry. Its consistent export performance to dozens of countries across continents and supply to major international oil companies underscores its global influence and reputation for quality.

During their visit, they toured our facility and were notably impressed with what they saw in particular, our automated facility, which aligned very favorably with their own standards of advanced technology and operational efficiency.
Given HYST’s strong global profile, full-value chain capability, extensive experience with OCTG and other tube products, and its reputation for quality and compliance, such a partnership could position us well to leverage HYST’s manufacturing strength and global supply network, while combining with our existing facility’s automation to achieve efficient and high-quality OCTG delivery. Their positive impression of our facility, especially as an automated plant, provides a solid basis for moving forward with discussions. We believe collaboration could bring mutual value: combining HYST’s manufacturing depth and product breadth with our local presence and operational capacity.
