上海钢管产量从1949年的16吨提高到43万吨,其中:无缝钢管13万吨,焊接钢管30万吨。钢管品种从单一的汽焊管发展到能生产各种无缝或焊接的碳素钢、合金钢、轴承钢、不锈钢钢管以及各种精密合金、高温合金管、波纹管、镀锌管、双金属管、异型管、金属软管等。产品大的到五米三,小的仅一毫米;重的一根超过一吨,轻的只有0.2克;最长的达六十米,短的仅仅五毫米。上海已成为我国钢管产品门类比较齐全,品种规格比较配套,以生产小型钢管为主的工业基地,在国内占有相当比重。目前,上海的无缝钢管工业已具有一定的水平,除了尚在建设中的宝钢一四○连轧管机组外,还拥有φ100、φ76毫米自动轧管机组各一套,φ76、φ100毫米热穿孔机各一台,可生产φ57～121毫米的热轧无缝钢管。在冷加工方面,上海已拥有各种冷轧管机26 Shanghai’s steel pipe production increased from 16 tons in 1949 to 430,000 tons, of which 130,000 tons of seamless steel pipe and 300,000 tons of welded steel pipe. Pipe varieties from the development of a single steam pipe to produce a variety of seamless or welded carbon steel, alloy steel, bearing steel, stainless steel and a variety of precision alloy, superalloy, bellows, galvanized pipe, bimetallic tube , Special-shaped pipe, metal hose and so on. The product is large to five meters three, a small one millimeter; a heavy one more than a ton, light is only 0.2 grams; the longest of sixty meters, a short of only five millimeters. Shanghai has become China’s steel pipe product category is complete, more varieties and specifications supporting the production of small steel pipe-based industrial base, occupy a considerable proportion of the country. At present, Shanghai seamless steel pipe industry has a certain level, in addition to the Baosteel is still under construction 14,0 pipe mill units, but also has φ100, φ76 millimeters of automatic pipe rolling a set of φ76, φ100 mm thermal perforation Each one machine, can produce φ57 ~ 121 mm hot-rolled seamless steel tubes. In the cold processing, Shanghai has a variety of cold-rolled pipe machine 26
