Description
Technical field:
The present invention relates to the steel pipe hydrostatic testing technical field, is a kind of pre-water filling steel tube hydraulic test method and specialized equipment thereof specifically.
Background technology:
Steel pipe hydrostatic testing generally adopts hydrostatic testing machine at present, is used to check steel pipe body density and bearing capacity, is the process equipment of high value added product indispensabilities such as production flow line pipe, tubing and casing.
Its hydraulic testing principle: use special-purpose hydraulic testing pressure head that external seal is carried out at the two ends of steel pipe, and in the steel pipe body, fill with liquid pressure medium and (be generally emulsion with steel pipe antirust function, hereinafter to be referred as " water "), suppress then, when after the pressure in the body reaches given pressure, continuing pressurized cylinder stroke that pressurize reaches official hour or adopt ftercompction less than the numerical value of regulation, think that promptly steel tube surface do not suppress medium and reveal, judge that then steel pipe hydrostatic testing is qualified.
According to the hydraulic testing principle of steel pipe, present hydrostatic testing machine realizes that the main technique flow process of steel pipe hydrostatic testing is: steel pipe material loading-pre-align-flushing tube chamber-enter pressure testing station-pressure head advances and finishes pre-sealed-water-filling exhaust to the steel pipe two ends-suppress pressurize-steel pipe disengaging pressure testing position-empty test medium-discharging in the body.According to the mode difference that steel pipe enters the pressure testing station, present hydrostatic testing machine type can be divided into the horizontal hydrostatic testing machine of feeding and two kinds of types of vertical hydrostatic testing machine of following feeding.These two kinds of its common characteristic of type are carried out water-filling exactly on the pressure testing station, and just suppress after in judging tube chamber, not having air, it is longer that water filling process takies the effective operation time, this time determines that by caliber size and length caliber and pipe range are big more, and then required time is long more, the general filling time is about 10 seconds, that have even longer, it is very big that this makes that the rhythm of production of hydrostatic testing machine reduces, and this seriously restricts the production efficiency of industrialization line production.For solving the production efficiency problem of the hydraulic testing, many hydrostatic testing machines can only be installed also work simultaneously, investment is big like this, and floor area is big, and operative employee's number increases, thereby increases production cost of products.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and a kind of pre-water filling steel tube hydraulic test method is provided.
Another object of the present invention provides a kind of specialized equipment of pre-water filling steel tube hydraulic test method.
The present invention mainly solves problems such as existing steel tube hydraulic test method efficient is low, production cost height.
In order to achieve the above object, the present invention is achieved in that a kind of pre-water filling steel tube hydraulic test method, and its special character is that it comprises following processing step:
A washes steel pipe internal-surface;
B immerses the steel pipe after the flushing and suppresses in the medium (being generally the emulsion with steel pipe antirust function, hereinafter to be referred as " water "), when suppressing medium and be full of the steel pipe inner chamber, with suppressing a sealed steel pipe two ends, directly suppresses, pressurize;
C suppresses, discharging after the pressurize.
The specialized equipment of a kind of pre-water filling steel tube hydraulic test method of the present invention, it comprises rotary flushing machine, its special character is that feed mechanism one end is connected with rotary flushing machine, the feed mechanism other end is connected with elevating mechanism, below elevating mechanism, establish medium box, in medium box, establish the pipe mover structure, elevating mechanism is corresponding with an end of pipe mover structure, on the pipe mover structure, establish clamp system, above clamp system, establish hydraulic testing mechanism, the other end of pipe mover structure is corresponding with the discharging mechanism of its top, the discharging mechanism liftable, and discharging mechanism is connected mutually with empty water mechanism.
Specialized equipment of the present invention, its described clamp system can be elevating mechanism.
Specialized equipment of the present invention is established the strut beam elevating mechanism in its described hydraulic testing mechanism.
A kind of pre-water filling steel tube hydraulic test method of the present invention and specialized equipment thereof, compared with the prior art have outstanding substantive distinguishing features and marked improvement, 1, the water-filling of steel pipe all is outside the pressure testing line, finishes in the off time of pressure testing, does not take the effective operation time; 2, the part of pressure testing equipment and pressure testing part auxiliary movement mechanism place the water tank of a upper shed, under the prerequisite that does not increase hydrostatic testing machine quantity, by change water-filling station, make the filling time not take the effective operation time, suppress production efficiency about 1/3rd thereby improve, thereby saved the cost of product, also reduced floor area.
