U type pipe and device is used in processing thereof

The utility model discloses a U type pipe, processing be with device and surface machining method, and U type pipe is formed with U type nozzle stub both ends face bonding respectively by two straight tubes, and the both ends face of U type nozzle stub be first non - horizontal plane, and the first non - horizontal plane at U type nozzle stub both ends edge U type nozzle stub the central axis is symmetrical, the welding end face of straight tube be with first nonaqueous surface matching's the non - horizontal plane of second, U type nozzle stub surface has unevenness's texture. The processing method includes venturi tube always admittedly on processingequipment, then will straighten the line that venturi tube surface machining becomes unevenness with the laser source, will straighten the venturi tube at last and buckle into U type nozzle stub. The utility model discloses a U type pipe long service life, it is more convenient to process. 本实用新型公开了种U型管，加工用装置及其表面加工方法，U型管由两个直管分别与U型短管两端面焊接而成，U型短管的两端面为第非水平面，且U型短管两端的
