Venting and sampling of fluid-filled pipe installations and containers - involves hollow externally threaded cylinder with bore end and thread-cutting structure at its one end and head at other end

摘要

A hollow externally threaded cylinder (1) has a bore end (2) and a thread cutting component (3) at its one end and a head (4) at its other end. The head is internally threaded. The cylinder with rotation movement and pressure force bores, threads and screws itself to a sealing device at the cylinder head. The cylinder head is provided with a sealing ring of flexible material. The threaded cylinder is provided with a hole through the wall towards the fluid. The hole can also be placed directly within the pipe conduit or container wall. The device incorporates a bore and thread swarf collecting part nearest the sepg. wall against the fluid and a sealing part against the cylinder thread. The device is applied against the pipe or container by adhesion or a self-adhesive body.
