ABSTRACT:
The union is made up of two parts normally locked together by at least one radial screw with sized cross section. Under severe pulling stress applied to the union from the outside the locking screw breaks and frees the two parts of the union, which separate together with the pipes to which they are attached. Under normal working conditions elastically stressed sealing devices ensure maintenance of watertightness between the union parts.
