Description

Steel pipe device for detecting water pressure

Technical field

The invention belongs to steel pipe hydrostatic tester tool technical field, be specifically related to a kind of steel pipe device for detecting water pressure.

Background technology

Above mentioned steel pipe refers mainly to seamless steel pipe (as follows), and seamless steel pipe includes hot rolled seamless steel tube and cold rolling, solid drawn tube.Owing to seamless steel pipe has hollow section, thus it is used as the pipeline of conveyance fluid in a large number, such as transfer oil, natural gas, coal gas and water etc..Seamless steel pipe is whether still quite varied in the application of industrial circle or even building field at military industry field, for military industry field, for satellite, aircraft, naval vessel etc., for industrial circle, more for boiler manfacturing and power generating equipment, for building field, more it is used as scaffold.

In order to ensure the quality of steel pipe, generally in addition to Steel Pipe Eddy Detection and/or ultrasonic inspection being detected in sampling observation mode, in addition it is also necessary to carry out hydraulic pressure test (detection of the most aforesaid hydraulic pressure), to grasp the water pressure resistance anti-leakage degree of steel pipe.

nullThe technical information about steel pipe device for detecting water pressure can be seen in disclosed Chinese patent literature，Typically recommend there be " steel pipe hydrostatic tester " such as Authorization Notice No. CN202770609U，Steel pipe can be made hydraulic pressure test and use the quality to steel pipe and accomplish to know what's what by this patent formula，Degree of possessing，And the 0012nd section of famous technique effect of its description can be embodied，But there is following shortcoming: one is owing to can only test a steel pipe every time，Thus the desired comprehensive test request of steel pipe's production manufacturer cannot be met，Because the production efficiency of steel pipe is the highest，If by root (by propping up) test，So certainly will delay the opportunity of product export，Even occur that (overstocking) phenomenon piled up by steel pipe to be measured，If but tested in sampling observation mode，Cannot ensure the most again the most all can reach required quality index with a batch of all steel pipes；Two is to be tested by the manual operation of online assignment personnel owing to needing, thus the test operation working strength of workman is big；Three is owing to artificially participation is i.e. tested by manual operations, thus test difficult quality guarantee, because the factor such as the quality of test quality and the experience of tester, physical ability, psychology, responsibility has certain relation.Certainly, if strengthening the quantity of " steel pipe hydrostatic tester ", first shortcoming in the most aforementioned 3 shortcomings can eliminate, but the quantity being to increase " steel pipe hydrostatic tester " also needs to increase tester in addition to the input testing cost that takes up room, increases, thus causes the waste of the human resources of preciousness.Moreover second, third some shortcoming aforesaid can not be eliminated owing to increasing " steel pipe water press testing machine ", thus sheerly Zhi Biao rather than effect a permanent cure and for the passive measure attended to one thing and lose sight of another.
