The reason for the fracture of the fitting joint: It may be that the movement of the fitting causes the joint to break. Some fittings move without noticing the position of the joint, which can lead to breakage of the joint. Sometimes some joints will appear whitish, which is actually a precursor to breakage. For the joints, it is actually a kind of laceration. When moving the pipe fittings, be sure to pay attention to the distance, take care of the position of the joint, and do not pull it forcefully. Even though the toughness of the fittings is relatively good, the joints cannot withstand such a heavy force. The impact of surrounding objects will directly lead to the fracture of the pipe fittings. If the direct impact is not strong, it may have little effect on the pipe fittings, but it will have a greater impact on the joints. The joints are all curved, not straight. After impact, it will deform and directly lead to fracture. The general pipe fittings are resistant to low temperature and will not affect the use in extremely cold weather. But there is a problem, and that is in the absence of liquid. If the liquid freezes, frequent thermal expansion and contraction will shorten the practical life. When using pipe fittings, we must pay attention to giving the joint a good use environment to avoid certain damage to the joint.
