双金属管件加工技术

Processing technology of double metal pipe fittings

随着双金属复合管的推广应用,双金属复合管制造和焊接技术不断发展,但是由于双金属复合管特殊结构(大部分为机械复合),在焊接过程中仍然有许多技术难点,通过对双金属复合管坡口的改进,解决了双金属复合管在不等壁厚焊接过程中的技术难点。

Along with the popularization and application of double metal composite pipe,double metal composite pipe manufacturing and development of welding technology, but due to the double metal composite pipe special structure （mostly mechanical composite）, during the welding process,there are still many technical difficulties, based on improved double metal composite pipe slope mouth, solved the double metal composite pipe in unequal wall thickness of difficuhies in the process of welding technology welding.
