Description
Technical field
The utility model is related to process for making gas piping technical fields, more particularly to a kind of gold for gas piping
Belong to compensator.
Background technology
It is metal hose used in gas piping design before the burner of the boiler of script, material is 304 stainless steels.By
Do not consider to contain higher chloride ion content in blast furnace gas when original designs, and 304 stainless steel anti-chlorine ion corrosions are not high.
The installation length of metal hose is longer simultaneously, and processing technology is connected by welding using two sections of bellowss, therefore
This intermediate weld seam is also easy to happen corrosion and leaks, and the blast furnace gas metal before burner just often occurs after going into operation 1 year
Hose seriously corroded, leakage coal gas, drastically influence the safe and stable operation of production.
Invention content
The technical problem to be solved by the utility model is to provide a kind of metal compensators for gas piping, have knot
Structure is simple, service life is long, improvement cost is low, avoid the occurrence of discarded leakage phenomenon, the corrosion resistance of raising pipeline, reduces repair
The features such as expense.
Technical solution adopted by the utility model to solve its technical problems is：A kind of metal for gas piping is provided
Compensator, including intermediate tube, end pipe and bellows, the intermediate tube both ends are symmetrically installed with end pipe, and the end pipe is in
Between be connected by bellows between pipe, the bellows is the stronger 254SMo stainless steels of anti-chlorine ion corrosion, described
It is disposed with erosion resistant coating on the inner wall of intermediate tube, end pipe and bellows, two circle lugs, institute are disposed in the middle part of the intermediate tube outer ring
A circle lug is disposed in the middle part of the end pipe stated, two circle lugs of the intermediate tube pass through drawing with the lug in two end pipes respectively
Bar is connected.
Two end pipes are separately installed with mounting flange and loose flange on one end opposite with intermediate tube.
The pull rod is connected by fixing nut and locking nut with lug.
Washer and spring washer are installed between the locking nut and lug.
Advantageous effect：The utility model is related to a kind of metal compensators for gas piping, have simple in structure, use
Long lifespan, improvement cost are low, avoid the occurrence of discarded leakage phenomenon, the corrosion resistance of raising pipeline, reduce the features such as maintenance cost.

Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiment of the utility model is related to a kind of metal compensator for gas piping, as shown in Fig. 1-2, packet
Intermediate tube 6, end pipe 2 and bellows 4 are included, 6 both ends of intermediate tube are symmetrically installed with end pipe 2, the end pipe 2 and intermediate tube
It is connected by bellows 4 between 6, the bellows 4 is the stronger 254SMo stainless steels of anti-chlorine ion corrosion, in described
Between pipe 6, end pipe 2 and bellows 4 inner wall on be disposed with erosion resistant coating 5, be disposed with two circle lugs in the middle part of 6 outer ring of intermediate tube
3,2 middle part of the end pipe is disposed with a circle lug 3, two circle lugs 3 of the intermediate tube 6 respectively in two end pipes 2
Lug 3 is connected by pull rod 8.
Two end pipes 2 are separately installed with mounting flange 1 and loose flange 7 on one end opposite with intermediate tube 6.
The pull rod 8 is connected by fixing nut 9 and locking nut 10 with lug 3.
Washer and spring washer are installed between the locking nut 10 and lug 3.
Embodiment
By the structure of metal hose alternative costs technical solution, during use, since bellows 4 is anti-chlorine ion corrosion
The stronger 254SMo stainless steels of property, intermediate tube 6, end pipe 2 and 4 inner wall of bellows are disposed with erosion resistant coating 5 so that intermediate tube 6, end pipe
2 and bellows 4 be not easy to be greatly improved the service life of the metal compensator by chloride ion corrosion, simultaneously because selection be
Bellows 4 can significantly facilitate replacement, reduce cost.
