Description

A kind of stiffening plate weld inspection method
Technical field
The present invention relates to a kind of weld inspection methods, specifically, being a kind of stiffening plate weld inspection method.
Background technique
In petrochemical industry, stiffening plate can play reinforcing effect to Petroleum Storage Tank and pipeline tapping position, it is ensured that The stability and safety of storage tank and Pipe installing component.After welding with reinforcement plate, the air-tightness of reinforcement plate welding seams is tried Testing is a wherein important ring.Gas compression is entered into component reinforcement region by stiffening plate leakage signal indicator hole, in weld seam External application foaming agent, to check whether weld seam has bubble to emerge to determine whether to leak.Traditional detection method, because of reinforcement The leakage signal instruction bore open of plate is small, often relatively difficult to the pressurization of stiffening plate inner inflatable by leakage signal indicator hole, It is troublesome in poeration.
Therefore known stiffening plate weld inspection method there are problems that it is above-mentioned various inconvenient and.
Summary of the invention
The purpose of the present invention is to propose a kind of storage tank reinforcement plate welding seams for facilitating stiffening plate leakage signal instruction gas inlet hole Detection method.
To achieve the above object, the technical solution of the invention is as follows:
A kind of stiffening plate weld inspection method, it is characterised in that include the following steps:
A, it before on welding with reinforcement plate to storage tank or pipe element, is welded on stiffening plate leakage signal indicator hole one section long Degree >=200mm, diameter are greater than the gauge pipe of stiffening plate leakage signal instruction bore dia, make stiffening plate leakage signal indicator hole and instrument Sealing welding is made in table pipe junction, after welding gauge pipe on leakage signal indicator hole, then weld storage tank stiffening plate to storage tank or On person's pipe element;
B, after welding with reinforcement plate, during carrying out the detection of stiffening plate weld joint air-tight, connected by gas-guide tube described in Gauge pipe detects the inflated spatial pressurization in storage tank stiffening plate;
C, after stiffening plate weld seam detection, the gauge pipe is removed with sanding machine.
Storage tank stiffening plate weld inspection method of the invention can also be further achieved by the following technical measures.
Method above-mentioned, wherein the gauge pipe is stainless steel gauge pipe.
After adopting the above technical scheme, storage tank stiffening plate weld inspection method of the invention has the following advantages that:
1, welding is easy to operate for the stainless steel gauge pipe of air guide;
2, the air inlet for facilitating welding with reinforcement plate rear enclosed space, can guarantee in intake process, and gas source is close with indicator hole inlet port Feng Xing;
3, it hunts leak easy to operate, reduces testing cost.

Specific embodiment
With reference to embodiments and its attached drawing further explains the present invention.
Embodiment 1
Stiffening plate weld inspection method of the invention, includes the following steps:
Fig. 1 is the reinforcement plate structure diagram of the embodiment of the present invention.
A, before on welding with reinforcement plate to pipe element, a segment length is welded on stiffening plate leakage signal indicator hole 1 For 200mm, diameter indicates the stainless steel gauge pipe 2 of bore dia slightly larger than stiffening plate leakage signal, will pass through stainless steel instrument Pipe carries out air inlet or outlet to leakage signal indicator hole.Fig. 2 is soldering stainless steel gauge pipe on the stiffening plate of the embodiment of the present invention Schematic diagram.On leakage signal indicator hole after soldering stainless steel gauge pipe, then weld on storage tank stiffening plate to pipe 5.Fig. 3 is this The welding with reinforcement plate for having welded stainless steel gauge pipe of inventive embodiments is on pipe.
B, it after on welding with reinforcement plate to pipe 5, during carrying out weld joint air-tight detection, is connected by gas-guide tube 3 The stainless steel gauge pipe 2 detects the inflated spatial pressurization in pipe stiffening plate.
Fig. 4 is that the air-tight test of the embodiment of the present invention terminates to be removed stainless steel gauge pipe with sanding machine.
C, after pipe stiffening plate weld seam detection is qualified, the stainless steel gauge pipe is removed with sanding machine.
The present invention have substantive distinguishing features and significant technological progress, storage tank stiffening plate weld inspection method of the invention, The a bit of stainless steel gauge pipe for air guide is welded on indicator hole on stiffening plate, can be convenient welding with reinforcement plate rear enclosed The air inlet in space, can guarantee in intake process, gas source and indicator hole inlet port leakproofness, while also facilitate operation.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field Member, without departing from the spirit and scope of the present invention, can also make various transformation or variation.Therefore, all equivalent Technical solution also should belong to scope of the invention, should be limited by each claim.
