Description
Technical field
The present invention relates to the press and open holes operations of pipeline, are blocked more particularly, to a kind of steel lining multiple tube pipeline press and open holes
Method.
Background technology
The conveyance conduits such as oil, natural gas, chemical industry, often require that relocated in the state of medium on-line production,
The construction operations such as valve or danger leakage reparation are replaced, that is, need pipeline stopping transportation pressure plugging holes, it will be as shown in Figure 1.Pipeline changes
Some only several meters of the distance of line, some are such as to the plugging holes program of one section of pipeline to be repaired up to tens kilometers：Exist first
Trunk Line both ends welding packet mode by-pass tee to be repaired and closure threeway, to by-pass tee press and open holes, connect inicdental bypath；
Kaifeng plug-hole with pressure in threeway is blocked, is blocked using stopple plugging machine；Both ends carry out excision old pipeline after blocking, more renew pipe again
The construction operation in road；Construction finishes, and plays end socket, and off-chip is passed through pipe nipple and the stifled welding of plug；Stifled be sent into will be filled in using mechanical means
Threeway, and fixed with snap ring（The position for being sent into off-chip has been subjected to calculating with measuring）；Valve is finally removed, lid blind plate is completed to apply
Work industry.This kind of method introduces China from last century the eighties, has been used widely, and effect is fine.But the work
Industry method is only applicable to carbon steel pipe, and the oil in China, natural gas and chemical industry conveyance conduit only part are gone back using carbon steel pipe
There are some using steel lining multiple tube, including steel lining PA tube（PP is managed）, steel lining vinyl chloride pipe（Pvc pipe）, the poly- second of steel lining
Alkene pipe（PE is managed）, poly- four ethylene tube of steel lining（F4 is managed）Deng, bonding force between the lining and inner wall of steel lining multiple tube in 7CN/cm,
If steel lining multiple tube is carried out press and open holes, the steel pipe and internal lining pipe of tapping are cut open, carry out according to the method described above simultaneously
It is deficient to steel pipe and the sealing of internal lining pipe bonding place although plug is stifled to have carried out effective sealing to outer steel pipe after closure
It lacks, the media such as oil product, gas or water can still enter from incision between steel pipe and internal lining pipe, and for a long time, whole pipeline just loses
The effect of internal lining pipe is gone.
Invention content；
It is an object of the invention in view of the above-mentioned drawbacks of the prior art, providing a kind of multiple tube pipeline press and open holes
Method for blocking, to solve after steel lining multiple tube plugging construction steel pipe and the sealing problem of internal lining pipe bonding place at trepanning tube wall.
To achieve the above object, the present invention can take following technical proposals：
Multiple tube pipeline press and open holes method for blocking of the present invention includes the following steps：
The first step, using tapping equipment press and open holes on steel lining multiple tube according to a conventional method, the shape of a saddle material under cutting
Piece is taken out of by centre drill；
Second step, the accurate diameter for measuring trepanning on the outer diameter of shape of a saddle tablet and steel lining multiple tube, by its size difference system
It is for use to make the sealing ring being adapted with the material of pipeline medium；
Third walks, and the acute angle of shape of a saddle tablet cut surface changed into obtuse angle, and in its surface smear adhesive, by sealing ring
The plug used in trepanning is formed on its cut surface to block up；
Above-mentioned plug after the completion for the treatment of other construction operations, using mechanical means, is blocked up the trepanning being sent on multiple tube by the 4th step
It is in situ, the closure of multiple tube trepanning can be completed after being fixed using threeway snap ring.
Rubber material can be used in sealing ring.
The advantage of the invention is that encapsulating method is simple, sealing effect is good, the shape of a saddle tablet under being cut using trepanning+
The method of sealing ring carries out the closure sealing of trepanning, and the cost of material is low, is opened after solving steel lining multiple tube plugging construction well
Steel pipe and the sealing problem of internal lining pipe bonding place at the tube wall of hole.

Specific embodiment
More detailed explanation is done to the method for the present invention below by specific embodiment.
Multiple tube pipeline press and open holes method for blocking of the present invention includes the following steps：
The first step welds packet mode threeway at Trunk Line both ends first, compound in steel lining according to a conventional method using tapping equipment
Press and open holes on pipe（The facewidth of cylinder knife can be 14mm）, the shape of a saddle tablet 1 under cutting（Including outer steel pipe layer and liner tube layer）
It is taken out of by centre drill 2, as shown in Figure 1；
Second step, the accurate diameter for measuring trepanning on the outer diameter of tablet 1 and steel lining multiple tube use mold by its size difference
It is for use to manufacture rubber seal 3（The thickness of sealing ring is greater than the facewidth of a knife）, as shown in Figure 2 and Figure 3；
Third walks, and the acute angle of 1 cut surface of tablet is changed into obtuse angle, and in its surface smear adhesive（Due to rubber seal
Circle has certain retractility, and the general bonding agent such as AB glue can be selected in adhesive）, rubber seal 3 is mounted on its cut surface,
Mounted sealing ring 3 can envelope outer steel pipe layer and liner tube layer together, as shown in Figure 4；
As shown in figure 5, using mechanical means, the tablet 1 with rubber seal 3 is sent on multiple tube 4 for 4th step
Trepanning is in situ, and the purpose of sealing is can reach after being fixed using threeway snap ring.
Method present invention employs shape of a saddle tablet+sealing ring under trepanning is cut carries out closure sealing to trepanning,
Sealing ring can envelope the notch of steel pipe and internal lining pipe simultaneously, and after pipeline works normally, the media such as oil product, gas or water are not
It can enter between steel pipe and internal lining pipe from incision, ensure that the effect of internal lining pipe.
