Therefore, be adhered to socket through the power of restoring, to keep its watertightness because of the formed desire of the expansion of pipe.At this, because of forcing the assembling pipe, therefore, need bigger power during assembling, and when decomposing, need draw and to decompose with bigger power too.
In addition, if decompose after using the long period, then because of the pipe expansion, it is big that internal diameter becomes; Therefore, when reusing, it is big that the possibility of leaking becomes, thereby in order to improve the possibility of leaking; Need cut off the position of expansion and use afterwards, therefore, comparatively inconvenience, and cause waste.
In addition, though when internal tube pressure is low, can not go wrong, when becoming high pressure, because of the pressure inside pipe can be decomposed, drainage takes place.
In addition, the situation of utilizing belt to combine shown in figure 15 is to insert naturally to socket after pipe is assembled or pipe is assembled in pressure a little, utilizing the fastening again mode once of pipe racks.
At this, because of using pipe racks, can keep watertightness well, but, make Ministry of Foreign Trade and Economic Cooperation force to shrink, thereby will cause footpath portion to be out of shape, in the time of seriously even will break pipe because fastening and tighten pipe racks with pipe racks.
In addition, tightening of pipe racks needs other instrument, therefore, comparatively inconvenience, and because of externally having used pipe racks, its outward appearance is also received influence.
