Abstract
This utility model is related to a kind of corrosion-resistant corrugated expansion joint, including corrugated tube, the two ends of the corrugated tube are symmetrically welded with adapter, described take over into rectangular structure, one end of the adapter is provided with inclined-plane, the setting of other end bottom is jagged, and the indentation, there corrosion-resistant welding rod is welded with one section of overlay cladding, and the indentation, there of the adapter is with corrugated tube end by being welded together.This utility model compact conformation, rationally, easy to operate, by welding the effect of overlay cladding in the junction of adapter and corrugated tube, increase the bonding area of corrugated expansion joint medium carbon steel and stainless steel parts, under same corrosion rate, compensator can use the longer time, can accomplish substantially and the pipeline same life-span, substantially increase functional reliability.
Description
Technical field
This utility model is related to corrugated expansion joint technical field, especially a kind of corrosion-resistant corrugated expansion joint.
Background technology
Corrugated expansion joint has been widely used in engineering, and etching problem is the key factor for affecting product service life.
After metallurgy industry gas piping is using dry method dust, its corrosion to pipeline is very serious, especially rotten to pipeline carbon steel part
Erosion speed is faster.Use through examining from system corrugated expansion joint for many years, the system bellows compensator is often in ripple
Pipe and adapter weld corrode, and cause gas leak.Found by analysis, the main cause for producing this phenomenon is stainless
The location contacts area of steel and carbon steel welding is too little, and after the carbon steel part contacted with rustless steel steel is corroded, compensator will
Leakage.
Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, there is provided a kind of corrosion-resistant corrugated expansion joint, so as to
Corrugated tube and adapter weld corrosion-resistant problem are effectively solved, and anticorrosive effect is substantially, with low cost.
The technical scheme adopted by this utility model is as follows：
A kind of corrosion-resistant corrugated expansion joint, including corrugated tube, the two ends of the corrugated tube are symmetrically welded with adapter, described
Take over into rectangular structure, one end of the adapter is provided with inclined-plane, other end bottom arranges jagged, and the indentation, there is with resistance to
Corrosion welding rod is welded with one section of overlay cladding, and the indentation, there of the adapter is with corrugated tube end by being welded together.
Its further technical scheme is：
The overlay cladding and corrugated tube head contact, the lower surface of the adapter down gap and the upper table of corrugated tube end
Face contacts；
The corrugated tube adopts corrosion-resistant stainless steel material.
The beneficial effects of the utility model are as follows：
This utility model compact conformation, rationally, easy to operate, overlay cladding is welded by the junction in adapter and corrugated tube
Effect, increase the bonding area of corrugated expansion joint medium carbon steel and stainless steel parts, under same corrosion rate, compensator
The longer time can be used, can accomplish substantially and the pipeline same life-span, substantially increase functional reliability.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of this utility model adapter.
Wherein：1st, take over；2nd, overlay cladding；3rd, corrugated tube；4th, inclined-plane；5th, breach.
Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the corrosion-resistant corrugated expansion joint of the present embodiment, including corrugated tube 3, the two ends of corrugated tube 3
Adapter 1 is symmetrically welded with, 1 one-tenth rectangular structure of adapter, one end of adapter 1 are provided with inclined-plane 4, and other end bottom arranges jagged
5, one section of overlay cladding 2 is welded with corrosion-resistant welding rod at breach 5, connected by welding with 3 end of corrugated tube at the breach 5 of adapter 1
It is connected together.
Overlay cladding 2 and 3 head contact of corrugated tube, the lower surface of 1 down gap 5 of adapter and the upper surface of 3 end of corrugated tube
Contact.
Corrugated tube 3 adopts corrosion-resistant stainless steel material.
In actual manufacture process, first in one section of breach 5 of bottom car of adapter 1, section corrosion-resistant welding rod at the breach 5
(mating with corrugated tube 3) welds one section of overlay cladding 2, it is ensured that overlay cladding 2 is close to the wall thickness of adapter 1 with 5 contact length of breach.
Corrugated tube 3 adopts corrosion-resistant stainless steel, material to be selected according to dielectric corrosion situation.
This utility model increases the bonding area of corrugated expansion joint medium carbon steel and stainless steel parts, in same corrosion speed
Under degree, compensator can use the longer time, can accomplish substantially and the pipeline same life-span.
Above description is to explanation of the present utility model, is not the restriction to utility model, and this utility model is limited
Scope can make any type of modification referring to claim within protection domain of the present utility model.
