Technical field
The invention discloses a kind of pipeline pressure testing method, particularly relate to the pressure measurement side of the spiral steel pipe of a kind of band reinforcing ring
Method.
Background technology
At present, the pressure testing method of spiral welded steel pipe is mainly hydrostatic pressure test, its objective is that inspection spiral welded pipe is
Whether no infiltration and weld seam can bear pressure and not ftracture, and specific practice is to be sealed by spiral welded pipeline end face
Stifled, and in other end face toward priming petock in body and form certain water pressure.This test method needs the most complicated instrument
Device, the steel pipe of different-diameter is accomplished by more transducer set closure mould, and the biggest steel pipe of diameter is in order to ensure the intensity of pressure instrumentataion
It is the biggest that the volume of its equipment is accomplished by doing.And this kind of test method is will to fill water in body, the pressure measurement of large diameter steel pipe
Being accomplished by substantial amounts of water, waste water resource is the most serious.And do this test presently more than the pipeline of more than 4 meters will be the most tired
Difficult.
It would therefore be highly desirable to solve above-mentioned technical barrier.
Summary of the invention
Goal of the invention: it is an object of the invention to provide a kind of easy to operate and save the spiral testing simple band reinforcing ring
The pressure testing method of steel pipe.
Technical scheme: the pressure testing method of the spiral steel pipe of a kind of band reinforcing ring of the present invention, comprises the steps:
First, the tested reinforcing ring both ends on the spiral steel pipe of band reinforcing ring are blocked；
Secondly Pressure gauge and perfusing hole are arranged on spiral steel pipe, and communicate inside tested reinforcing ring, then toward perfusion
Perfusion liquid or gas in mouthful, and form certain pressure, stop perfusion and see whether manometric air pressure declines, if under air pressure
Dropping then weldquality defective, it is qualified that air pressure does not decline then weldquality.This pressure testing method is without being poured in liquid or gas
Whole steel pipe, reduces the waste of water resource；And need not large-scale equipment, simplify test method；It is greatly shortened filling material
Time, saved test period, improve production efficiency；The most limited by the field, it is more suitable for the pipe detection of Large Diameter Pipeline.
Wherein, the spiral steel pipe of described band reinforcing ring around being formed, is formed helical form by main steel coil strip between adjacent main steel band
Seam, and tested reinforcing ring is fastened at this spiral seam.Welding quality at this spiral seam requires maximum, also and
Crack easily occurs, admittedly detect weldquality at this is that whether detection spiral steel pipe permeates and whether weld seam can bear pressure
And there is not the key point of cracking.
Further, the end of described tested reinforcing ring is blocked by plugging plate, can realize envelope by modes such as welding
Stifled.
Preferably, described Pressure gauge and perfusing hole are arranged on the plugging plate of same side end face of spiral steel pipe；Or, described
Pressure gauge and perfusing hole are separately positioned on the plugging plate of both sides end face of spiral steel pipe.Or, described Pressure gauge and perfusing hole
It is arranged on winding in a spiral manner to fasten on the tested reinforcing ring being located on the outer wall of spiral steel pipe.Can according to detection place,
The objective condition unrestricted choice instrument setting position of detection equipment or testing staff, flexible operation degree is high and applied widely.
Beneficial effect: compared with prior art, the present invention has following remarkable advantage: first this pressure testing method is without by liquid
Body or gas are poured in whole steel pipe, reduce the waste of water resource；And need not large-scale equipment, simplify test method；Greatly
The big time shortening filling material, save test period, improve production efficiency；The most limited by the field, it is more suitable for managing greatly
The pipe detection in footpath；The placement location of Pressure gauge and perfusing hole is flexible and changeable simultaneously, can according to detection place, detection equipment or
The objective condition unrestricted choice instrument setting position of testing staff, flexible operation degree is high and applied widely.

Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is described further.
As shown in Fig. 1, Fig. 9, the pressure testing method of the spiral steel pipe of a kind of band reinforcing ring, comprise the steps:
First, tested reinforcing ring 2 both ends on the spiral steel pipe 1 of band reinforcing ring are blocked, tested reinforcing ring 2
End is blocked, as shown in Figure 4 and Figure 5 by plugging plate 6.
Secondly Pressure gauge 3 and perfusing hole 4 are arranged on spiral steel pipe 1, and communicate with tested reinforcing ring 2 inside, perfusion
External filling apparatus on mouth 4, by filling apparatus 7 again toward perfusion liquid or gas in perfusing hole 4, and forms certain pressure,
Stopping perfusion and see whether the air pressure of Pressure gauge 3 declines, if air pressure declines, weldquality is defective, and air pressure does not decline then weld seam
Up-to-standard.This pressure testing method, without liquid or gas are poured in whole steel pipe, reduces the waste of water resource；And need not
Large-scale equipment, simplifies test method；It is greatly shortened the time of filling material, has saved test period, improve production effect
