Abstract
The utility model 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; and the enveloping outer diameter of the hydrostatic-test compensator is 96% of the inner diameter of the corresponding pipe for the hydrostatic test, and the lengths of the outermost edge of the two ends of the hydrostatic-test compensator are less than the length of the tested pipe by 50mm-150mm. 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 utility model relates to machinery manufacturing technology field, the method that relates in particular to a kind of hydraulic testing compensator and carry out the tubing hydraulic testing.
Background technology
According to the requirement of pipe standard or tubing technical specification book (like GB/T 9711, API SPEC 5L), the tubing (or other pressure-bearing pipe material) as oil gas is carried need carry out the hydraulic testing (ruggedness test and Leakage Test).And hydraulic testing link often becomes the controlling unit (time of this operation is longer relatively) of pipe production line production capacity, and after the external diameter of steel pipe increased (more than reaching like 813mm), hydraulic testing link was more remarkable to the influence of pipe production line production capacity.Show in the existing test of Hydraulic test technique that inflow is big, the time long, inefficient problem, often become the control bottleneck in the steel pipe's production link heavy caliber pipe.
The utility model content
The purpose of the utility model is to design a kind of novel hydraulic testing compensator, addresses the above problem.
To achieve these goals, the technical scheme of the utility model employing is following:
A kind of hydraulic testing compensator; Said hydraulic testing compensator carries out the right cylinder that the big or small external pressure of tubing hydraulic test pressure is not damaged for bearing to be not less than, and said right cylinder is solid cylinder perhaps adopts the end socket sealing for two ends a hollow shell structure.
The envelope external diameter of said hydraulic testing compensator is corresponding 96% of the hydraulic testing pipe internal diameter that carries out, the length of its two ends outer most edge than the little 50mm to 150mm of the pipe length of testing.
Said hydraulic testing compensator evenly distributes 3 circles along its length with top sheave or bearing, and every circle is adorned more than 6,, the installation direction of said pulley or said bearing is made the direction of axially-movable for ease of said hydraulic testing compensator.
Said hydraulic testing compensator be that light material is processed, can bear and be not less than the external pressure that carries out tubing hydraulic test pressure size and the right cylinder that is not damaged.
Said 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 is advanced to hydraulic testing compensator and treats in the pressure testing tubing;
In second step, said hydraulic testing compensator waited that testing tubing is fixed on the hydrostatic testing machine together with the compensator clamping;
The 3rd step, carry out the hydraulic testing according to the method for routine, test is released said hydraulic testing compensator after accomplishing from proof tubing;
The 4th step repeated three steps of the first step to the, realized the hydraulic testing to tubing.
Said 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 the prior art; When tubing is carried out the conventional hydraulic testing, will wait to test the tubing clamping and be fixed on the hydrostatic testing machine, the tubing two ends sealed through mechanical hook-up; Treat test tubing inner chamber subsequently through the hydraulic pamp water-filling; And carry out supercharging through 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 and has promptly been accomplished the hydraulic testing to this Zhi Guancai.
The utility model is exactly through 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.
The beneficial effect of the utility model can be summed up as follows:
1, in the utility model, 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 efficient of the raising hydraulic testing.
2, adopt the utility model also might adopt gas medium to replace aqueous medium (or other liquid mediums) to carry out pressure test.The cavity volume that carries out pressure test behind the employing hydraulic testing compensator is greatly reduced, and the medium amount that gets in the pressure test like this is by greatly less, even adopt gas medium also can guarantee higher security.

Embodiment
Clearer for technical matters, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Like Fig. 1 to a kind of hydraulic testing compensator shown in Figure 4; Said hydraulic testing compensator carries out the right cylinder that the big or small external pressure of tubing hydraulic test pressure is not damaged for bearing to be not less than; Said right cylinder is a solid cylinder, in other embodiment, also can adopt the hollow shell structure of end socket sealing for two ends; The envelope external diameter of said hydraulic testing compensator is corresponding 96% of the hydraulic testing pipe internal diameter that carries out, the length of its two ends outer most edge than the little 50mm to 150mm of the pipe length of testing; Said hydraulic testing compensator be that light material is processed, can bear and be not less than the external pressure that carries out tubing hydraulic test pressure size and the right cylinder that is not damaged.
In the embodiment that is more preferably; Said hydraulic testing compensator evenly distributes 3 circles along its length with top sheave or bearing; Every circle is adorned more than 6; The installation direction of said pulley or said bearing is made the direction of axially-movable for ease of said hydraulic testing compensator, and said 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,
A advances hydraulic testing compensator and treats in the pressure testing tubing (hydraulic testing compensator length must than treating that hydraulic testing pipe length is little), and can fill in smoothly and wait to test tubing also be to treat a kind of latus rectum that test tubing carries out to check to hydraulic testing compensator like this.
What b will fill in hydraulic testing compensator waits that testing tubing is fixed on the hydrostatic testing machine together with hydraulic testing compensator clamping, carries out the hydraulic testing according to the method for routine then.
