我国小直径精密管有着广阔的发展前景，调查表明，到1995年需求量为1.8X10*~2X10*,外径44.76~10 (12) mm的小直径精密管主要用于电冰箱、制冷、汽车制造、机械、电气和轻工业等方面。长期以来，使用部门主要采用铜管、玲拔钢管和双层制钎焊我管(邦迪管》。其生产工艺复杂。成本高。随着电焊钢管技术的进步,焊管质量的提高，用冷乳带钢作原料，通过成型一爆接--冷或径的方法，直接生产高质量的小直径精密焊管的新工艺被广泛采用。由于其生产工艺简单、效率高、质量好、成本飫，在很多领域铜管、冷拔管或邦迪管已逐步被精密烘管取代。日本中4.76mm的精密烨管广泛用于冰箱創造业，西德用φ1om以下的精密焊普制造汽车的刹车系统。
The survey shows that the demand for small diameter precision tubes in 1995 is 1.8X10*~2X10*, and the diameter of small diameter precision tubes is 44.76~10(12) mm. They are mainly used in refrigerators, refrigeration, automobile manufacturing, machinery, electrical and light industries. For a long time, the use departments mainly adopt copper pipe, Lingpu steel pipe and double-layer brazing my pipe (Bondi pipe). Its production process is complex. High cost. With the development of electric welded steel pipe technology and the improvement of welded pipe quality, the new technology of directly producing high quality small diameter precision welded pipe with cold latex strip as raw material by forming a burst joint-cold or diameter method has been widely used. Because of its simple production process, high efficiency, good quality and low cost, copper tubes, cold drawn tubes or Bondi tubes have been gradually replaced by precision drying tubes in many fields. Japan's 4.76mm precision Ye tube is widely used in refrigeratory creation industry, while West Germany manufactures automobile brake system with precision welding under 1 om.
1987年前后，我国已从澳大利亚引进3条邦迪管生产线,年产量为25001/线。另外，从意大利，土耳其引进多条双层管生产线，加上其他单层管生产线，生产能力已远远超过1x 10*t。因此建设:
Around 1987, China has introduced three production lines of Bondi Pipe from Australia, with an annual output of 25001/line. In addition, from Italy and Turkey, several double-layer pipe production lines have been introduced, together with other single-layer pipe production lines, and the production capacity has far exceeded 1 x 10*t. Therefore, construction:
①根据因内的市场和现有的工艺装备状况，1995年以前最多再新建2~ 4条小直径精密焊管生产线。目前，山东、红苏、四川。河南等地正在新建或拟建这类生产线，请决策者慎重全面考虑。
According to the domestic market and the existing technological equipment, a maximum of 2-4 small diameter precision welded pipe production lines were built before 1995. At present, Shandong, Hongsu and Sichuan. Henan and other places are building or planning to build such production lines. Policymakers should consider them carefully and comprehensively.
②新建的小直径精密焊管机组应采用新型高频感应焊。它不仅经济效益好，而且对扩大品种规格(φ25mmx 1mm)锴力很大。
(2) New type of high frequency induction welding should be adopted in the newly built small diameter precision welded pipe unit. It not only has good economic benefits, but also has great power to enlarge variety specifications (25mmx 1mm).
