A fabricated water pressure cap for pressure test of standing piping of architecture

摘要

end. The technical field to which the invention described in the claims belongs.;The present invention relates to a prefabricated hydraulic cap for pressure testing, and more particularly, to enable a simple airtight test of a pipe connected to and connected to a standing pipe of a building to be constructed.;I. The technical problem the invention is trying to solve.;In order to install the airtight test pressure gauge to one end of the conventionally constructed pipe, a man plug is welded to the end of the pipe and a pressure gauge is installed to perform a pressure leak test, and there is no leakage. As the work continues, the unnecessary work of welding and cutting the man plug is repeated every time the pressure leakage test is performed, which may cause damage to the pipe and delay in the process, and there is a problem in that the cost of the man plug is consumed. .;All. The gist of the solution of the invention.;The packing interposed between the fastener and the connector which is fitted to the end of the granular pipe and is fixed and coupled to each other is pressed to achieve airtightness.;la. Important uses of the devise;For confidentiality test.
