【History of Haichuan Pipes】China’s first factory for producing seamless steel pipes from special steels was established
Thread Content
China’s first factory for producing seamless steel tubes was established in 1959, when the Shanghai Cold-Drawn Steel Tube Factory put into operation a Φ76mm piercing machine along with a corresponding cold-drawing tube production line. Shortly after its commissioning, it was integrated into Shanghai Iron and Steel Plant No. 5, becoming a special steel enterprise that focused on the production of alloy and stainless seamless steel tubes. In 1960, the factory successfully produced 18-8 (304) stainless steel billets on a Φ76mm piercing machine, and via cold drawing it manufactured China’s first batch of stainless steel tubes for aviation conduits. It is the first seamless steel tube factory in China’s special steel plants, and one of the main manufacturers of cold-drawn tubes for military use in the country.

The factory was built in October 1958, with further construction taking place after 1961; it was subsequently renovated and expanded on several occasions until the end of 1989. The total amount of investment spent on construction to date has reached 949 million yuan. The total area of the factory is 2.34 million square meters. The industrial building area is 509,600 square meters, while the area of non-production buildings is 496,000 square meters. It has open-hearth steelmaking. Steel production using electric furnaces, tube rolling at 216 and 318 millimeters, tube expansion to 650 millimeters, seamless tube production at 100 millimeters, cold rolling and drawing of tubes, as well as eight other production facilities for tube processing; along with corresponding equipment manufacturing, power supply systems, transportation facilities, and utility systems. The large-scale 318-millimeter tube rolling machine in the factory is the largest project there, with its main equipment imported from Hungary. The design was carried out by the Chongqing Institute of Iron and Steel Technology, while construction was undertaken by the Fifth Metallurgical Construction Company under the Ministry of Metallurgy. The main factory building has two spans, each measuring 24 meters in length. It is 648 meters long, including an additional span; its construction area amounts to 40,200 square meters. It features three production sections for raw materials, hot rolling, and finishing processes, and is equipped with supplies of water, electricity, heat, gas, air compression, and high-pressure water. There are 9 major systems, including communications, railways, and roads, comprising a total of 19 engineering projects and 36 individual projects, with a total of 2,664 sub-projects. It was completed and put into operation in November 1965, and on December 31, 1965, China’s first large-diameter seamless steel pipe was produced there.
