Background technique
At present, the gathering line in petroleum and petrochemical sector or to place underwater Corrosion of Pipeline very serious has directly influenced the working life of pipeline, causes the extra increase of construction cost and overall cost.In order to alleviate and prevent the corrosion and damage of conveyance conduit, improve its working life, the general employing applies corrosion-inhibiting coating or lining to metal pipe internal wall.The Placement of now general anti-corrosion pipeline has flange connection, the connection of joint socket rubber sealing and welding etc.; Because the flange connection all requires sealing material to have antiseptic property and high temperature resistant when being connected with cushion rubber; Increase cost, and had shortcomings such as poorly sealed, intensity difference; So for intensity and the sealing that improves the pipeline connection part, general adopt economical and reliably welding manner connect.But the metallic conduit that adopts anticorrosive coat is when welded and installed, and the high temperature that welding is produced will destroy the anticorrosive coat of weld joint; This has not only influenced interior corrosion-resistant effect, makes it lose the function of protection pipeline, has reduced its sealing; And easy local etching and cause perforation when serious; Thereby influence the life-span of whole piece pipeline, be difficult to inspection and maintenance under water, cause enormous economic loss.
The model utility content
The utility model provides a kind of simple in structure, easy for installation to the defective that existing technology exists, and sealing and antiseptic property are good, and linking intensity is high, can prevent pipe leakage, prolongs the pipeline internal corrosion-proof pipe pipeline joint linkage structure in working life.
For solving the problems of the technologies described above; The technological scheme of the utility model is: internal corrosion-proof pipe pipeline joint linkage structure, comprise pipeline body, and the jointing of said pipeline body end is provided with the joint greater than the pipeline body external diameter; The exterior edge face of said joint is provided with seal space; Be equipped with anticorrosive coat in said pipeline body inwall and the seal space, said anticorrosive coat is an integral structure, the corresponding contact of the anticorrosive coat in the adjacent two pipeline body joint seal spacies; The joint of two pipeline bodies welds together, and weld bond is diametrically away from anticorrosive coat.
Said seal space is arranged on the space between adjacent two joints or is arranged on the annular groove greater than said pipeline body internal diameter of joint end.
Said joint is provided with and is used for adjacent two pipeline body positioning means for positioning.
Said positioning device is socket and the bellmouth that is separately positioned on the joint of adjacent two pipeline bodies, and said socket and bellmouth are suitable.
Said positioning device comprises locating slot that is arranged on the said joint and the positioning ring that is arranged in the said locating slot.
Anticorrosive coat in the said annular groove is set to the concave-convex inserting structure.
Said joint is jumping-up moulding or casting.
Said joint is welded on the end of pipeline body.
After having adopted technique scheme; The beneficial effect that the utility model is obtained is: the jointing through at pipeline body is provided with joint; And the external diameter of joint is greater than the external diameter of pipeline body, and the joint with adjacent two pipeline bodies welds together at jointing like this, and weld bond is diametrically away from anticorrosive coat; Can make solder joint away from anticorrosive coat through this structure; High temperature when preventing to weld damages anticorrosive coat, has not only improved the antiseptic property and the sealability of pipeline, has also improved the linking intensity at pipe joint place simultaneously; End through at joint is provided with seal space; Anticorrosive coat also is set, and the anticorrosive coat on anticorrosive coat in the seal space and the pipeline body inwall is set to integral structure, the corresponding contact seal of the anticorrosive coat during connection in the adjacent two pipeline body joint seal spacies in seal space; Not only improved the overall tightness of pipeline through this structure; Can effectively prevent pipe leakage, and improve the antiseptic property of whole pipe, prolong the working life of pipeline.
