Technical field
The present invention relates to machinery manufacturing technology field, particularly relate to a kind of water pressure test compensator and carry out hydraulic pipe test
Method.
Background technology
According to pipe standard or the requirement of tubing Technical specification (such as GB/T 9711, API SPEC 5L), as oil-gas transportation
Tubing (or other pressure-bearing pipe material), need to carry out the water pressure test (ruggedness test and Leakage Test).And water pressure test ring
Joint often becomes the controlling unit (time of this operation is relatively long) of pipe production line production capacity, when the external diameter of steel pipe increase (as
813mm and more than) after, water pressure test link is more significantly on the impact of pipe production line production capacity.Existing Hydraulic test technique
To showing in the test of heavy caliber pipe, inflow is big, time length, inefficient problem, has often become in steel pipe's production link
Control bottleneck.
Summary of the invention
It is an object of the invention to design a kind of novel water pressure test compensator, solve the problems referred to above.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of water pressure test compensator, described water pressure test compensator carries out hydraulic pipe test pressure size for bearing to be not less than
External pressure and the cylinder that is not damaged, described cylinder is solid cylinder or the hollow shell using end socket to seal for two ends
Structure.
The envelope external diameter of described water pressure test compensator is to carry out the 96% of water pressure test pipe internal diameter accordingly, its two ends outer most edge
Length 50mm to 150mm less than tested pipe length.
Described water pressure test compensator is uniformly distributed 3 circles along its length with top sheave or bearing, and often circle fills more than 6, described
The installation direction of pulley or described bearing makees the direction of axially-movable for ease of described water pressure test compensator.
Described water pressure test compensator be that light material is made, can bear to be not less than and carry out outside hydraulic pipe test pressure size
The cylinder pressed and be not damaged.
Described light material is foamed materials or cellular material.
A kind of method utilizing described water pressure test compensator to carry out hydraulic pipe test, it is characterised in that comprise the steps:
The first step, in being advanced to treat pressure testing tubing by water pressure test compensator；
Second step, is fixed on the tubing to be tested of described water pressure test compensator on hydrostatic testing machine together with compensator clamping；
3rd step, conventionally carries out the water pressure test, after having tested, by described water pressure test compensator from testing
Tubing in release；
4th step, repeats the first step to the 3rd step, it is achieved the water pressure test to tubing.
Described water pressure test compensator has two or more, repeats to switch use.
The pressure medium carrying out the water pressure test is liquid medium or gaseous medium.
In prior art, when tubing is carried out the conventional water pressure test, tubing clamping to be tested is fixed on hydrostatic testing machine, logical
Cross machinery tubing two ends are sealed, treat test tubing inner chamber subsequently and pass through hydraulic pamp water-filling, and entered by booster pump
Row supercharging, to reach force value voltage stabilizing corresponding time at this pressure of the water pressure test, pressure release subsequently by tubing inner chamber
Water discharge i.e. complete the water pressure test to this Zhi Guancai.
The present invention is through the appropriate design to the water pressure test, shortens the water pressure test time, uses such hydraulic pressure to try simultaneously
Proved recipe formula can realize the latus rectum inspection to steel pipe.
Beneficial effects of the present invention can be summarized as follows:
1, in the present invention, because water pressure test compensator bears the ability of external pressure so that it is in hydraulic pipe process of the test
Do not deform, water inlet and the time of draining when so can greatly reduce the water pressure test, thus reduce pipe
The overall time of the material water pressure test, improve the efficiency of the water pressure test.
2, use the present invention to be also possible to use gas medium to replace aqueous medium (or other liquid mediums) to carry out pressure examination
Test.The cavity volume carrying out pressure test after using water pressure test compensator is greatly reduced, such pressure
The medium amount entered in test is by the most less, even if using gas medium also to can guarantee that higher safety.

Detailed description of the invention
In order to make technical problem solved by the invention, technical scheme and beneficial effect clearer, below in conjunction with accompanying drawing and
Embodiment, is further elaborated to the present invention.Should be appreciated that specific embodiment described herein is only in order to explain
The present invention, is not intended to limit the present invention.
A kind of water pressure test compensator as shown in Figures 1 to 4, described water pressure test compensator is managed for bearing to be not less than
The external pressure of material hydraulic test pressure size and the cylinder that is not damaged, described cylinder is solid cylinder, in other reality
Execute the hollow shell structure that end socket can also be used to seal for two ends in example；The envelope external diameter of described water pressure test compensator is for enter accordingly
The 96% of row water pressure test pipe internal diameter, the length 50mm to 150mm less than tested pipe length of its two ends outer most edge；Institute
State water pressure test compensator be that light material is made, can bear be not less than carry out hydraulic pipe test pressure size external pressure and not
The cylinder being damaged.
In embodiment more preferably, described water pressure test compensator is uniformly distributed 3 circles along its length with top sheave or bearing,
