According to the invention, the pipe pressure testing apparatus is applied to a pipe hydraulic pressure intensity test of a workshop of a ship factory, such as a workshop hydraulic pressure intensity pressure test of pipes including a pressure load pipe, a ballast pipe, a fire-fighting pipe, a bilge water pipe, a fuel feed pipe and the like, can satisfy pipe hydraulic pressure intensity tests with various pressure requirements in the workshop of the ship factory, and has the function of realizing multiple purposes in one apparatus.
Description
Technical field
The present invention relates to a kind of pressure tester for tubes.
Background technology
Ship pipe occupies very important effect and share during being produced on shipbuilding at present.According to statistics, the making of pipe and the workload of installation account for about the 20% of whole shipbuilding quantities, and almost each shipyard has the professional pipe atelier of oneself.Pipe is after workshop makes, whether pipe reaches requirement with the weld of flange, if there is leakage scenarios, this is accomplished by being verified by pipe hydraulic pressure strength, and the hydraulic pressure strength test of pipe to be also shipowner and ship examine the project extremely paid close attention to, be shipowner and ship inspection must look into project.Tested by pipe hydraulic pressure strength, can determine whether the fine or not situation of tube welding quality.
In this context, shipyard is badly in need of a kind of tooling device to meet the demand of pepe shop pressure testing, and it is simple, practical, flexible to operation and use the features such as safety that it has making, and can reach disposably to put into, the permanent purpose used.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of pressure tester for tubes, can meet the requirement of shipyard workshop pipe pressure test, have one and fill multiplex function.
The present invention solves that its technical problem the technical scheme is that
A kind of pressure tester for tubes, including main pipeline, a plurality of lateral, two flanges, blank flanges, two flanges are separately mounted to the initial and end end of main pipeline, blank flange is arranged on the flange of main pipeline tail end, described a plurality of lateral is distributed in main pipeline both sides along main pipeline length direction, every lateral one end connects with main pipeline, the other end is for connecting with pressure testing pipe, being provided with stop valve, pressure gauge valve, Pressure gauge on every lateral, described Pressure gauge is arranged on pressure gauge valve.
Further, described main pipeline and lateral are respectively adopted seamless steel pipe making.
Further, described seamless steel pipe plating zinc on surface processes.
Further, described lateral is provided with for installing the nipple one being connected with pressure testing pipe, and for installing, with pressure gauge valve, the nipple two being connected.
Further, described nipple one, nipple two are respectively welded on lateral.
