精密焊管的制造技术与应用

Manufacture Technology and Application of Precision Welded Pipe

精密焊管比一般焊管几何尺寸精确,焊缝和焊管内外表面质量优良,壁厚均匀,可直接或经少量加工用于设备构件中,在化工、纺织机械、航空、仪表、汽车等行业中得到广泛应用。论述了精密焊管的生产方式、用途和使用性能,精密焊管的制管工艺和生产装置,精密焊管生产中几个关键技术问题和技术质量标准以及高质量精密焊管的生产。

Comparing with common welded pipe,precision welded pipe has many advantages such as accurately geometry dimensions,superior quality of weld seam and inside and outside welding surface,uniform wall thickness,and can be directly or less processing applied on the component of equipment,etc.Therefore,precision welded pipe has been widely used on chemical industry,textile mechanics,aviation,meter and automobile industry,etc..This article states the manufacturing mode,application property and purpose of precision welded pipe,the pipe manufacture process and production equipment of precision welded pipe,several key technical issues during the production of the precision welded pipe and standard for technology and quality as well as manufacture for precision welded pipe with superior quality.
