【History of Haichuan Pipes】In 1958, China’s specialized large-scale seamless steel pipe factory – Chengdu Seamless Steel Pipe Factory
Thread Content
In 1958, it was decided that in the southwestern region of our country, utilizing three sets of main tube rolling equipment from Hungary (Φ133mm jacking pipe machines and Φ216, 318mm rolling mills), a large-scale, specialized seamless steel tube factory with a complete range of facilities – the Chengdu Seamless Steel Tube Factory – would be designed, constructed, and operated independently by our country, covering the entire process from tube billet production to the delivery of finished seamless steel tubes (including those used for geological purposes and oil wells).

When I was studying in Tianjin, I also heard about a key project: the Tianjin Large Seamless Project.
It’s possible to guess your age; it was during the 1980s and early 1990s, and later it seems to have become part of Tianjin Iron and Steel
When it comes to the Chengdu Seamless Steel Pipe Factory, old residents of Chengdu are all aware of it. This factory used to be the largest steel plant in Chengdu, the largest seamless steel pipe manufacturer in all of China, and the largest seamless steel pipe manufacturer in entire Asia. Like the classified factories of the third front at that time, this factory also had three names. One is the Chinese name of the factory: Chengdu Seamless Steel Pipe Factory ； There is also one where the factory name is replaced by a number, called Factory 65 ； The mailing addresses all use mailboxes: XXX, Box XX, Sub-box XX, Mailbox No. 249, Chengdu. This factory is located in Niushikou, on the eastern outskirts of Chengdu. The Bull Market Entrance is located outside the East Gate of Chengdu. I’m not sure whether it’s because there is a Chengdu Seamless Steel Pipe Factory in Niu Shi Kou that it became famous, or rather, it’s Chengdu Seamless Steel Pipe Factory that became famous because of its location in Niu Shi Kou. In other words, it’s unclear whether Bull Mouth or Chengdu Seamless Steel Pipe Factory is the better one! -Niuniukou was originally the most important starting point on the Chengyu Highway, Sichuan Province’s key road connecting Chengdu and Chongqing. In the 1930s and 1940s, the bus departure point from Chengdu to Chongqing was located at Niu Shi Kou. At that time, Bui Tou Kou was a transportation and economic hub, on par with Yan Shi Kou. Buses departing from Chengdu start from Niu Shikou, head straight to Shahepu, then to Longquanyi, and finally to Chongqing. (Image 1 shows the map before the seamless steel pipe factory was built; there was a road from Niu Shikou to the Normal College, and buses also ran on that route.)
