U型弯头在化工行业经常用到,由于弯头用于承压设备及管道上,所以在使用前必须进行水压试验。U型弯头水压试验工序如下:编制焊接工艺→焊条烘干→工组对弯头→持证焊工施焊→水压试验→焊工切割→钳工划加工线→镗床平端面加工坡口。可以看出,此种水压试验工序复杂,材料消耗大,生产周期长。为此,我们制作了1套U型弯头试验装置,实际应用后,提高了劳动生产率10倍。 U-bend often used in the chemical industry, the elbow used for pressure equipment and piping, so before use must be hydrostatic test. U-bend hydraulic test procedure is as follows: preparation of welding process → electrode drying → work group on the elbow → Welder welding welding → hydraulic pressure test → welder cutting → clamp machined line → boring machine flat surface processing groove. It can be seen that such a hydrostatic test procedure is complicated, the material is consumed, and the production cycle is long. To this end, we have produced a set of U-bend test device, the practical application, increased labor productivity 10 times.
