Abstract
The utility model relates to a direct welding type antisepsis pipe joint on the connection part between fluid transportation pipelines after preservative treatment. The pipe joint comprises an antisepsis pipe joint body, an inner coating layer and an outer coating layer respectively positioned on the inner wall and the outer wall of the antisepsis pipe joint body and compounded with the inner wall and the outer wall thereof. Bevels for welding are formed on a first end and a second end of the antisepsis pipe joint body; and the second end is far away from the inner coating layer and the outer coating layer. The antisepsis pipe joint has the advantages of simple structure, convenient connection of the pipelines, no internal repaired mouth after the connection of the pipelines, small fluid resistance, corrosion resistance, being capable of prolonging service life of the pipelines.
Description
Technical field:
The utility model relates to a kind of directly welded anti-corrosion pipe joint that between fluid-transporting tubing after the preservative treatment and fluid-transporting tubing connection part place does not need internal joint patch that is used for.
Background technique:
Fluid-transporting tubing after internal and external anti-corrosive is handled; the small-bore pipeline that connects with welding manner particularly; in laid processes; because the inwall of pipeline bond sites is difficult to adopt the method for coating to be protected; the metal of welding part is with after Korrosionsmedium contacts; cause the corrosion premature failure of conveyance conduit, thereby influence the working life of pipeline because of connection part.
The model utility content:
In view of above reason, the purpose of this utility model is in order to provide a kind of simple in structure, and that pipeline links is convenient, pipeline need not internal joint patch after connecting, and has that fluid resistance is little, corrosion-resistant, the directly welded anti-corrosion pipe joint of the advantage that can improve pipeline working life.
The purpose of this utility model is achieved like this:
The utility model directly welded anti-corrosion pipe joint, comprise the anti-corrosion pipe fittings body, lay respectively at inside and outside coating compound with it on the inside and outside wall of anti-corrosion pipe fittings body, on first termination of anti-corrosion pipe fittings body and second termination, the bevel for welding and second termination are arranged respectively away from inside and outside coating.
Outer little interior big groove is arranged on the above-mentioned anti-corrosion pipe fittings body inwall, have on the undercoating and stretch into auxiliary section compound with it in the groove.
Groove on the above-mentioned anti-corrosion pipe fittings body inwall is an annular groove.
The sectional shape of the groove on the above-mentioned anti-corrosion pipe fittings body inwall is trapezoidal.
First termination of the anti-corrosion pipe fittings body in two the utility model is welded in an end of the defeated delivery pipe of two fluids respectively, and make inside and outside coating cover the weld seam of connection fully and form complete compound body, with the second termination butt welding in two the utility model anti-corrosion pipe fittings bodies, be about to two pipeline weldings and be integral then.Welding between two fluid-transporting tubings can be carried out in the job site of laying.Like this, when conveying has the fluid of Korrosionsmedium, after the weld seam of Korrosionsmedium and pipeline connection part and the corrosion resistant metal around the weld seam contact, can effectively delay the extent of corrosion of weld seam, thus the working life of having improved pipeline greatly.
The utility model is simple in structure, and pipeline is easy to connect, need not internal joint patch after pipeline connects, and have fluid resistance little, corrosion-resistant, can improve the pipeline advantage in working life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model construction drawing.
Embodiment:
Referring to Fig. 1, this directly welded anti-corrosion pipe joint, comprise anti-corrosion pipe fittings body 1, lay respectively at undercoating 2 compound with it on the inside and outside wall of anti-corrosion pipe fittings body, external coating 3, on first termination 4 on the anti-corrosion pipe fittings body, second termination 5, the bevel for welding 6,7 and second termination are arranged respectively away from inside and outside coating.It is trapezoidal annular groove 8 that outer little interior big sectional shape is arranged on the anti-corrosion pipe fittings body inwall, has on the undercoating and stretches into auxiliary section compound with it in the groove 9.
Fig. 2 is the utility model directly welded anti-corrosion pipe joint 10 and two fluid-transporting tubings, 11 connection diagrams.
Claims (4)
