Abstract
The present invention relates to pipeline interconnection methods.Stainless steel pipes weld argon gas pressurize saving construction method, it includes, and takes two pieces of sponge circular blocks；Each sponge circular block is clamped with two panels circle plank, and one piece of sponge circular block center holes drilled through wherein, by tunger tube and a steel wire from a stainless steel tube outer end along inside pipe wall through two pipe docking place, tunger tube and steel wire are penetrated in that sponge circular block centre bore of trepanning, two sponge circular blocks are stretched into two stainless steel pipes to interface both sides respectively again, it is used in combination the steel wire to connect, tunger tube is reliably connected with two pieces of sponge circular block iron wires；Two stainless steel tubes are docked, one layer of Paper adhesive tape closing is first twined to interface；It puts argon gas and pressurize is carried out to weld, Paper adhesive tape sealing strip is cut open one section, open welding machine and welded, electric arc directly lights Paper adhesive tape in welding process, and welding finishes, and is extracted two pieces of sponges in pipe outside pipe with iron wire and tunger tube.The present invention can reduce argon gas usage amount, reduce cost.
Description
Technical field
The present invention relates to pipeline interconnection method, specifically stainless steel pipes argon gas pressurize welding procedure method.
Background technology
Usually in stainless steel pipes welding process, usually argon gas is used to carry out pressurize welding, it is ensured that welding quality.It does
Method is that first an argon gas appendix is stretched into from stainless steel pipes outer end in pipe, then by both ends nozzle on the outside of two stainless steel pipes
Closed, argon gas will be full of by then opening valve in stainless steel tube, finally carry out pressurize welding.Make to carry out welding one in this way
Road weld bond can consume a large amount of argon gas, and construction efficiency is low, and construction cost is high.
Invention content
The present invention is directed to overcome the deficiencies of existing technologies, a kind of stainless steel pipes welding argon gas pressurize saving construction side is provided
Method.The present invention can reduce argon gas usage amount, reduce cost.
In order to solve the above-mentioned technical problem, plugging device step is made, two pieces of sponge circular blocks are taken；Diameter is more than stainless steel
Bore；Each sponge circular block is clamped with two panels circle plank, and round plank diameter is less than stainless steel tube internal diameter；And wherein
One piece of sponge circular block centre drill small one and large one two through-hole, large aperture are consistent with argon gas pipe outside diameter；
Dock step, by tunger tube and a steel wire from a stainless steel tube outer end along inside pipe wall through two pipe docking place, argon
Tracheae and steel wire penetrate in the sponge circular block centre bore of trepanning, then two sponge circular blocks are stretched into two stainless steel pipes respectively
To interface both sides, the steel wire is used in combination to connect, tunger tube is reliably connected with two pieces of sponge circular block iron wires；
Two stainless steel tubes fix 3 spot welding after interface alignment, one layer of papery are first twined to interface by weld preparation step
Adhesive tape is closed；
Welding step first puts argon gas and carries out pressurize to weld, then Paper adhesive tape sealing strip is cut open 30mm long, open welding machine into
Row welds, and electric arc directly lights Paper adhesive tape in welding process, and welding finishes, and interior two pieces of sponges will be managed with iron wire and tunger tube
It extracts outside pipe.
The present invention makes simple, of low cost, install convenient, easy to carry.The present invention changes conventional construction method, ensures
Construction quality；Only original 5%-10%, reduces construction cost from the point of view of argon gas usage amount, greatly improves construction effect
Rate.
Description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the sponge circular block schematic diagram of the present invention；
Fig. 2 is the schematic diagram of the present invention.
Specific implementation mode
As shown in Figure 1：Mainly there are two sponge round block circles 1 to form by the present invention, and every piece of sponge round block thickness 80mm diameter is general
More than 2 internal diameter 60mm of stainless steel tube, then 3 tight sponge round block of two panels circle clip with wooden board is selected, round plank diameter is generally less than not
Become rusty pipe diameter 60mm.One of sponge round block centre-drilling hole, aperture are consistent with 4 outer diameter of tunger tube.
Construction before first by tunger tube and iron wire from a pipe outer end along inside pipe wall through two pipe docking place, tunger tube is penetrated
In one block of sponge round block center transfer port, then two pieces of sponge round blocks are filled in stainless steel pipes to interface both sides, two pieces of seas respectively
Continuous round block spacing 400mm.Two pieces of sponge round blocks are connected with iron wire, and tunger tube is reliably connected with two pieces of sponge round block iron wires.（It is stainless
Steel conduit finishes joint weld and is extracted 2 pieces of sponge round blocks in pipe outside pipe with iron wire and tunger tube）
Before welding starts：Two stainless steel tubes are aligned interface, one layer of Paper adhesive tape closing argon gas, welding are first twined to interface
Preceding argon gas of first putting cuts open 30mm long to weld progress pressurize, then Paper adhesive tape sealing strip, finally carries out welding job.Welding
Electric arc directly lights Paper adhesive tape in the process.20 weld bond institutes can be saved by welding one of weld bond according to this form of construction work
The argon gas amount needed.Pressurize form of construction work energy saving in this way is worth promoting in constructing afterwards.
