Abstract
A spigot-and-socket steel pipe connecting structure comprises turnups and flanges at two ends of the connection part of a pipe; the turnup is composed of a turnup flaunching and a turnup connection pipe; when a pipe to be connected is respectively inserted into the turnup connection pipes at two ends of the connection part, one end of the pipe is extended out of the turnup connection pipe and the other end is retracted into the turnup connection pipe; end edge of the turnup connection pipe is welded along the periphery of the pipe to hermetically seal the turnup with the pipe; the flange is sleeved on the turnup connection pipe, and flanges at two ends are fixedly connected. By use of the spigot-and-socket steel pipe connecting structure, the steel pipe is inserted into the turnup, the cooperation is close, the position is accurate, no misalignment is happened when welding, and the welding is convenient and reliable; furthermore, by use of the turnup/flange structure, beveled edges are not needed to be processed on the ends so that the technology is simple and the efficiency is high.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, especially is particularly related to a kind of spigot and socket type steel pipe linkage structure that pipeline connects that is used for.
Background technique
In industrial fields such as petrochemical industry, electric power, nuclear power, it is one of usual way that connects between pipeline, the pipe fitting that flange connects.Lap joint flange is applicable in the connection and corrosion-resistant pipeline of nonferrous metal such as steel, aluminium and stainless, acid resisting steel container or pipeline.Lap joint flange generally is to utilize flange, steel loop etc. that flange is enclosed within on the pipe end, and flange can be movable on pipe end, usually adopts the form of flange+lap joint flange.Steel loop or flange are exactly sealing surface, and the effect of flange then is that they are compressed.Owing to blocked by steel loop or flange, lap joint flange does not contact with medium.
Lap joint flange can be divided into downhand welding steel loop lap joint flange, the board-like pine cover of flange steel pipe flanges, three kinds of forms of welding neck collar pine cover steel pipe flanges.Existing welding neck collar pine cover steel pipe flanges is used for the connection between pipeline, the pipe fitting, the main butt joint type flange that adopts, be characterized in adopting the butt welding form to carry out being tightly connected between pipeline, pipe fitting and the flange at pipe end, the drawback of this welding is: butt welding easily misplaces, cause certain welding alignment tolerance, have influence on welding quality; And the welding end needs finished edge, manufacturing procedure complexity; It is longer to take over part, and more with the material amount, efficient is lower.
Summary of the invention
The purpose of this utility model is that the welding that overcomes existing butt joint type flange existence easily misplaces, poor welding quality, and the welding end needs finished edge, and the manufacturing procedure complexity is taken over problems such as part is long, a kind of spigot and socket type steel pipe linkage structure that pipeline connects that is used for of new structure is provided, steel pipe inserts flange and takes over inside, cooperates closely accurate positioning, the misalignment phenomenon can not take place during welding, convenient welding is firm; And this kind flange/flange arrangement does not need to carry out end processing bevel for welding, and technology is simple, the efficient height.
The purpose of this utility model realizes by the following technical solutions: a kind of spigot and socket type steel pipe linkage structure, the flange and the flange that comprise the pipeline junction both sides, flange is taken over by flange bead and flange and is formed, it is characterized in that: pipeline to be connected inserts respectively in the flange adapter of both sides, joint, one side pipe road stretches out outside the flange adapter, in opposite side pipeline indentation flange is taken over; Take over pipe end at flange and weld, flange is connected with described seal for pipe joints along described tube circumference; Described flange is enclosed within flange and takes over, and two side flanges connect fastening.
Described spigot and socket type steel pipe linkage structure after two side flanges are fastening, compresses flange, forms sealing surface.Described spigot and socket type steel pipe linkage structure can also comprise sealing gasket.
Described joint pipelines on two sides, a side are stretched out the outer part of flange adapter and are equated with the interior partial-length of opposite side indentation flange adapter.
Described flange connects fastening by bolt.
Described flange both can form with plate stamping and through machining, can also tubing and sheet material welding and form through machining.
Described flange can be made by carbon steel, stainless steel, alloyed steel sheet material or tubing according to the needs of practical application.
Spigot and socket type steel pipe linkage structure of the present utility model is compared with butt joint type flange/flange arrangement of the prior art, has following advantage and characteristics:
1) adopt spigot and socket type steel flange/flange arrangement, steel pipe inserts flange and takes over inside, cooperates closely, and accurate positioning the misalignment phenomenon can not take place during welding, and convenient welding is firm;
2) spigot and socket type steel flange/flange arrangement adopts above-mentioned welding method, need not carry out processing bevel for welding in end on flange and pipeline or pipe fitting, gets final product firm welding, and technology is simple, the efficient height;
3) spigot and socket type steel flange/flange arrangement is compared with butt joint type steel flange/flange arrangement, and its adapter will be shortened, and save and use material, reduce cost;
When 4) spigot and socket type steel flange/flange arrangement is used for the flange connection, utilizes and insert the engagement of taking between the inner steel pipe jog, be beneficial to being located by connecting between the flange, firm stablizing.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, protection domain of the present utility model does not exceed with embodiment, but is limited by claim.
