With so many seamless steel pipe plants in China, if you could only choose a few representatives, who would be the first to come to mind?

Today, we'll discuss them one by one, from north to south.

Let's start with Northeast China. Ansteel Seamless Steel Pipe Plant, put into operation in 1953, was the first seamless steel pipe plant in New China, known in the industry as the "cradle."

It has a production capacity of 500,000 tons/year, with specifications ranging from Φ60-180mm, mainly producing oil well pipes, pipeline pipes, and boiler tubes.

Ansteel is characterized by its strong foundation and stable technology, and has always had a good reputation in the petrochemical and machinery processing fields.

Next, let's look at North China. Tianjin Steel Pipe, known in the industry as "TPCO" (Great Seamless), has an annual production capacity of 3.5 million tons, of which more than 1.5 million tons are oil well pipes, placing it among the top tier of single-plant production capacity globally.

It leads domestically in high-end products such as deep-sea pipeline pipes, ultra-deep well oil well pipes, and high corrosion-resistant oil well pipes.

In short: Tianjin Steel Pipe is the first choice for national-level deep-sea and deep-well projects.

Baogang group, also located in northern China, leverages the rare earth resources of Baotou to possess unique advantages in corrosion-resistant and low-temperature resistant special pipes.

Its annual production capacity exceeds 1.2 million tons, with specifications ranging from Φ38-457mm. In 2025, its independently developed 690 MPa ultra-high strength structural pipe was already in mass production and supply.

Baogang has made rapid progress in high-end structural pipes and oil pipes in recent years, and has even obtained API certification.

In East China, Shandong Luli Group's seamless steel pipe production exceeded 3.37 million tons in 2023, ranking first in the country in terms of production and sales volume.

Its subsidiary brand, 'Panjin Steel Pipe,' has six advanced hot-rolling lines with a planned capacity of 6 million tons.

Luli's characteristics are large batch sizes, comprehensive specifications, and high cost-effectiveness, making it suitable for large-scale projects.

In Central China, Henan Fengbao Pipe Industry has invested 1.2 billion yuan in a large-scale, ultra-thick precision steel pipe project, with its hot-rolled seamless steel pipe production capacity soon to exceed 2 million tons.

Fengbao has filled the gap in its large-diameter seamless steel pipe production capacity, and its deep processing capabilities will account for over 60% of its total output.

The goal is to build a high-end base for oil pipes, structural pipes, and high- and medium-pressure boiler tubes.

Also in Central China, Hubei Daye Special Steel, founded in 1890, is known as the "cradle of modern Chinese steelmaking."

It has a production capacity of one million tons of high-end medium-thick-walled seamless steel pipes, with specifications ranging from Φ51-534mm and wall thicknesses from 5-130mm.

They dominate the market for engineering machinery pipes and high-pressure boiler tubes. For projects with high technical requirements, they are the right choice.

We've discussed several representative companies from Northeast, North, East, and Central China. In the next installment, we'll continue south to talk about Baosteel and the main plants under CITIC Pacific in East China, as well as a number of companies with strong export performance. Remember to follow us. "

We've talked about several major manufacturers in the north and central regions. This time, we're moving to East China and the south. One company everyone is familiar with is Baosteel, located in Shanghai."

East China: Baosteel, the "Third Pole" of High-Quality Long Products

Let's start with Baosteel. Located in Shanghai, it's a long-established powerhouse in our industry. Its 140-unit continuous rolling mill boasts the world's largest cumulative output of seamless steel pipes.

Energy-grade pipes are widely used in complex working conditions such as deep sea and deep earth environments, and its 13Cr corrosion-resistant oil well pipes have entered overseas markets.

In 2025, Baosteel invested 4.96 billion yuan to build a high-quality seamless steel pipe base, elevating high-quality long products to its third largest strategic product.

Baosteel is characterized by strong technological capabilities, rapid high-end product development, and consistently high R&D investment within the industry. "

Let's talk about CITIC Pacific Special Steel. It's not a single factory, but a group headquartered in Jiangyin, Jiangsu.

It owns five major production bases: Xingcheng Special Steel, Daye Special Steel, Qingdao Special Steel, Tianjin Steel Pipe, and Jingjiang Special Steel.

During the 14th Five-Year Plan period, CITIC Special Steel integrated the steel pipe resources of its various bases, increasing its overall seamless steel pipe production capacity to 5 million tons, making it the world's largest seamless steel pipe producer.

In short: it accounts for half of China's steel pipe exports.

Among CITIC Special Steel's subsidiaries, Jiangyin Xingcheng Special Steel is its flagship base, with an annual production capacity of 6.9 million tons of special steel.

Xingcheng's products are not limited to steel pipes, but it also produces bearing steel, automotive steel, and energy steel." Xingcheng's global leading position in the field sets a benchmark for the entire special steel industry.

Many technological breakthroughs and process innovations in seamless steel pipes rely heavily on the material support provided by leading special steel companies like Xingcheng.

Furthermore, Zhejiang Jiuli Special Materials is a hidden champion in the stainless steel seamless pipe field.

It specializes in special pipes such as 304, 316L, duplex stainless steel, and corrosion-resistant and high-temperature alloys, with specifications ranging from Φ6-219mm and wall thickness from 0.5-18mm, and a production capacity of approximately 40,000 tons.

Its products are used in nuclear power, petrochemicals, new energy, and marine engineering, with a gross profit margin exceeding 34%.

When it comes to stainless steel and special alloy pipes, Jiuli is an unavoidable name.

Further south, Hunan Hengyang Hualing Steel Pipe, founded in 1958... Jianchang is a globally influential professional seamless steel pipe enterprise.

Product specifications range from 32-762mm in diameter, and it can also produce rectangular and square tubes.

In 2025, it will cooperate with Danieli to build the world's largest extra-large diameter hot continuous rolling production line, designed with a maximum pipe diameter of Φ24 inches.

The highest steel grade for oil and gas pipes is HS155V, for line pipes it reaches X100Q, and for pressure vessel pipes it can withstand temperatures up to 600℃.

In short: a major force in high-end domestic production.

Finally, looking at Southwest China, Panzhihua Iron & Steel Group Chengdu Steel & Vanadium. With an annual production capacity of 2.12 million tons, its products cover oil pipes, boiler tubes, etc., and it has API certification and nuclear safety equipment manufacturing licenses.

Specifications: Φ6-720mm, wall thickness 0.5- 45mm seamless steel pipes have made significant contributions to industries such as national defense, aerospace, nuclear power, and boilers.

Pangang (Pangang Group) is the seamless steel pipe manufacturer in Southwest China with the most complete range of product specifications.

Of course, there are many other companies not mentioned, such as Jingjiang Special Steel, Qingdao Special Steel, Zhejiang Taifu, as well as Dalipu, Molong, Chengde, Longchuan, Jianlong, Huarun, Changjiang, etc. They are also making silent and enormous contributions to the country's energy construction, infrastructure, and export industry. We deeply admire them.

Our team has been in the steel pipe industry for 20 years and has long-term cooperation with these steel mills. Whatever type of steel pipe you need, we will help you find the most suitable supplier. You handle the order placement, and we will take care of the matching.
