我國小直徑精密管有著廣闊的發展前景，調查表明，到1995年需求量為1.8X10*~2X10*,外徑44.76~10 (12) mm的小直徑精密管主要用於（yú）電冰箱、製冷、汽車製造、機械、電氣和輕工（gōng）業（yè）等方麵。長（zhǎng）期以來，使用部門主要采用銅管、玲拔鋼（gāng）管和雙（shuāng）層製釺焊我管(邦迪（dí）管（guǎn）》。其生產工藝複（fù）雜。成本高（gāo）。隨著電焊（hàn）鋼管技術的進步,焊管質量的提高，用冷乳帶鋼作原料，通（tōng）過成型一爆接--冷或徑的方法，直接生產高質量的小直徑精密焊管的新工藝（yì）被廣泛采用。由於其（qí）生產工藝簡（jiǎn）單、效率高、質量好、成本飫（yù），在很（hěn）多（duō）領域銅管、冷拔管或邦迪管（guǎn）已逐步被精密烘管取代（dài）。日本中4.76mm的（de）精密燁管廣（guǎng）泛用於冰箱創造業，西德用φ1om以下的（de）精密焊普製造汽車的刹車係統。
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, automobiles 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 automobiles brake system with precision welding under 1 om.
1987年前後，我（wǒ）國已從澳大利亞（yà）引進3條邦迪管生產線,年產（chǎn）量為25001/線。另外，從意大利，土耳其引進多條雙層管生產線，加上其他單層管生產線，生產能力已遠遠超過1x 10*t。因此建設（shè）:
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根據因內的市場和現有的工藝裝備狀況，1995年以前最多再（zài）新建2~ 4條小直徑精密（mì）焊管生產線。目前，山東、紅蘇、四川。河南等地（dì）正在（zài）新建或擬建這類生產線，請決策者慎重全麵考慮（lǜ）。
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（de）小直徑精密焊管機組應采用新型高頻感應焊。它不僅經濟效益好，而且對擴（kuò）大品種規格(φ25mmx 1mm)鍇力很大。
(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).
