As a pioneer and leader in the production of medium-frequency hot-expanded steel pipes in China, the large-diameter hot-expanded steel pipes produced by the company fill the gap in domestic products, and to a certain extent change the situation of long-term dependence on imports of similar steel pipes in my country. They are widely used in the petroleum, chemical, electric power, heat network, gas cylinders, nuclear power, boilers and other industries, and have customized hot-expanded seamless steel pipes for more than 3,000 users in 32 countries and regions, totaling more than one million tons.

Over the years, our petrochemical pipes have been widely used in many large petrochemical projects in China, ensuring project construction and safe and reliable operation, fully reflecting our ability to supply pipes and provide project services. Thermal power pipe products lead the trend of gradually replacing welded pipes in domestic projects, and rank among the top in market share; gas cylinder pipe products are sold well at home and abroad, with tens of millions of dollars exported each year.

The company adheres to the business philosophy of "safety, high quality, integrity, everything for the users", and has won a good reputation and customer favor with its high-quality products and services. It has successively become a qualified supplier of alloy steel pipes and carbon steel pipes for Sinopec, a member unit of China Petroleum's "Energy No. 1 Network", a Class A material supplier for China Petroleum, a first-level member supplier for CNOOC, and a qualified supplier for many well-known companies such as China Coal, Sinochem, Huadian, Huaneng, China National Nuclear Corporation and military materials. It has won the "Top 100 Suppliers in China's Petroleum and Chemical Industry" for many consecutive years.
