Abstract
The invention discloses a hydrostatic test compensator. The hydrostatic test compensator is a cylinder which can bear the external pressure not less than the pressure size of the hydrostatic test for a pipe without damage; the cylinder is a solid cylinder or is in a hollow shell structure with the two ends sealed by adopting sealing heads. The invention also discloses a method of carrying out pipe hydrostatic tests, and the method comprises following steps: propelling the hydrostatic test compensator into a pipe to be tested, then fixing the pipe to be tested, which has been stuffed with the hydrostatic test compensator, and the hydrostatic test compensator to a hydrostatic test machine, and then carrying out hydrostatic tests according to normal methods. When the hydrostatic-test compensator is used for the hydrostatic test of the pipe, due to the capability of bearing the external pressure, the hydrostatic-test compensator is not deformed in the process of the hydrostatic test of the pipe, so that the water feeding time and the water discharging time in the hydrostatic test can be greatly reduced, and therefore the whole time for the hydrostatic test of the pipe is reduced and the efficiency of the hydrostatic test is increased.
Description
Technical field
The present invention relates to machinery manufacturing technology field, a kind of method that relates in particular to hydraulic testing compensator and carry out the tubing hydraulic testing.
Background technology
According to the requirement of pipe standard or tubing technical specification book (as GB/T 9711, API SPEC 5L), the tubing (or other pressure-bearing pipe material) of carrying as oil gas, need to carry out the hydraulic testing (ruggedness test and Leakage Test).And hydraulic testing link often becomes the controlling unit (time of this operation is relatively long) of pipe production line production capacity, after the external diameter of steel pipe increases (more than reaching as 813mm), hydraulic testing link is more remarkable on the impact of pipe production line production capacity.Show in the existing test of Hydraulic test technique to heavy caliber pipe that inflow is large, the time long, inefficient problem, often become the control bottleneck in the steel pipe's production link.
Summary of the invention
The object of the invention is to design a kind of novel hydraulic testing compensator, address the above problem.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of hydraulic testing compensator, described hydraulic testing compensator is not less than for bearing the right cylinder that the external pressure that carries out tubing hydraulic test pressure size is not damaged, and described right cylinder is solid cylinder or adopts the hollow shell structure of end socket sealing for two ends.
The envelope external diameter of described hydraulic testing compensator is corresponding 96% of the hydraulic testing pipe internal diameter that carries out, the little 50mm to 150mm of the tested pipe length of the Length Ratio of its two ends outer most edge.
Described hydraulic testing compensator is uniformly distributed 3 circles along its length with top sheave or bearing, and every circle fills more than 6, and the installation direction of described pulley or described bearing is made the direction of axially-movable for ease of described hydraulic testing compensator.
Described hydraulic testing compensator be that light material is made, can bear and be not less than the external pressure that carries out tubing hydraulic test pressure size and the right cylinder be not damaged.
Described light material is foamed material or cellular material.
A kind ofly utilize described hydraulic testing compensator to carry out the method for the tubing hydraulic testing, it is characterized in that, comprise the steps:
The first step, be advanced to hydraulic testing compensator to treat in pressure testing tubing;
Second step, be fixed in the tubing to be tested of described hydraulic testing compensator on hydrostatic testing machine together with the compensator clamping;
The 3rd step, carry out the hydraulic testing according to conventional method, after having tested, described hydraulic testing compensator released from proof tubing;
The 4th step, repeat the first step to the three steps, realizes the hydraulic testing to tubing.
Described hydraulic testing compensator has more than two, repeats to switch use.
The pressure medium that carries out the hydraulic testing is liquid medium or gaseous medium.
In prior art, when tubing is carried out to the conventional hydraulic testing, tubing clamping to be tested is fixed on hydrostatic testing machine, by mechanical hook-up, the tubing two ends are sealed, treat subsequently test tubing inner chamber by the hydraulic pamp water-filling, and carry out supercharging by supercharge pump, with the force value that reaches the hydraulic testing and under this pressure the corresponding time of voltage stabilizing, pressure release is subsequently also discharged the water in the tubing inner chamber to have completed the hydraulic testing to this Zhi Guancai.
The present invention is exactly by the appropriate design to the hydraulic testing, shortens the hydraulic testing time, adopts such hydraulic testing mode can realize the latus rectum inspection to steel pipe simultaneously.
Beneficial effect of the present invention can be summarized as follows:
1, in the present invention, because hydraulic testing compensator bears the ability of external pressure, it is not deformed in tubing hydraulic testing process, the time of water inlet and draining in the time of can greatly reducing the hydraulic testing like this, thereby the whole time of the minimizing tubing hydraulic testing, the efficiency of the raising hydraulic testing.
2, adopt the present invention also likely to adopt gas medium to replace aqueous medium (or other liquid mediums) to carry out pressure test.The cavity volume that carries out pressure test after employing hydraulic testing compensator is greatly reduced, and the medium amount entered in pressure test like this is by greatly less, even adopt gas medium also can guarantee higher security.
