Methods of reducing the defective rate of straight pipe fitting tee correctly

　　First, we should control the quality of pipe fitting tee at the source. All straight pipe fitting tees are made of seamless pipes from large factories, which can ensure that the defective rate of our straight pipe fitting tee is very low. Each model of equal pipe fitting tee is produced with the same force path, because one model has one set of mould. However, if the quality of the pipes is different, we can't see their differences directly, so we squeeze them with one force path. In the end, some models may be broken, but some models haven't been formed, So we can't control the reduction of defective rate.

　　Second, even if the mold needs to be inspected, the damage of the mold and the decrease of the air tightness are also the important reasons for the damage of the straight pipe fitting tee. Of course, the investment of a set of mold is also very large, and the damage caused by reluctant to renew the mold is inevitable.

　　Third, the training of skilled workers is also very important, and the skills of skilled workers are also one of the factors that affect the defective rate of pipe fitting tee.
