摘要:
The device is adapted to facilitate the assembly and disassembly of pipe sections in a blast downpipe. It comprises two flanges defining frustoconical bearing surfaces and a collar comprising clamping jaws which engage on said bearing surfaces. The collar is suspended from a support constructed in two parts, one of which parts is fixed and the other pivotally mounted on the first part. The collar may be clamped or unclamped by means of two screw and nut units.
