Abstract
The utility model relates to a non-welded stainless steel metal tube connected by a flange. In the utility model, a stainless steel metal soft net is sheathed on the outside of a spiral or an Omega bellows; the end parts of the bellows are sheathed with float rings; the three are welded and fixed; a flange is sheathed on the outside of the bellows between the float rings at the two end and can rotate freely. The non-welded stainless steel metal tube connected by a flange has the beneficial effects of: simple structure and low cost; having excellent performances of resisting high pressure, corrosion and high temperature as well as having excellent flexibility; being connected by a loose flange which is convenient for being connected with a customer pipeline; the soft connection mode which improves the working efficiency, avoid the high cost of a full-stainless steel structure and achieves the goals of low cost, high reliability and board application.
Description
Technical field
The utility model relates to a kind of various water, gas, the oil-piping flange-type joint that is flexible coupling, and especially relates to a kind of non-welding flange-connection stainless steel metal flexible pipe.
Background technique
As everyone knows, along with the joint of being made up of parts such as flange-connection stainless steel metal flexible pipes that is flexible coupling obtains continuous extensive use in various pipe-line systems, various requirements such as the displacement that a variety of causes of flexible and efficient pipeline construction, solution pipeline causes, solution Corrosion of Pipeline also improve constantly.Especially in the pipe-line system of deep-etching, all parts all connect at the flexible pipe that uses stainless steel to make, in the hope of reaching erosion-resisting purpose, so just make holding at high price of product, market expects that the flange-type stainless steel soft jointing of cheapness of fine quality occurs, to reduce the cost of engineering pipeline and equipment pipe.
At present, on the market, be the joint that is flexible coupling of main body manufacturing with the rubber hose, its price is the cheapest, still, and in the narrow limitation of a lot of occasions owing to its material, can't use, for example: in the occasion that is higher than 120 degree, rubber hose begins deliquescing, its intensity declines to a great extent, play drum, cracking, cause pipeline to reveal, and in the pipe-line system of some acid mediums and highly corrosive, because the corrosion resistance of rubber is poor, and can not use; Being connected of rubber hose and flange plate etc., can only adopt the mode of detaining, processing is consequently leaked at the place of detaining easily based on the joint that is flexible coupling of corrugated stainless steel tubing.
Now, domestic most of producers can only produce U type bellows because process equipment and processing technology are more backward, because adopt the oil pressure moulding, manufacturing efficiency is low, its cost height, and withstand voltage lower, ductility is relatively poor, therefore, during the manufacturing that U type bellows is used for expansion joint more is produced.
The model utility content
The purpose of this utility model is to overcome above-mentioned defective, and a kind of non-welding flange-connection stainless steel metal flexible pipe is provided, and it has abandoned U type bellows, has adopted withstand voltage and excellent spirality of ductility and Ω type bellows, has reduced cost.
The utility model is achieved through the following technical solutions: a kind of non-welding flange-connection stainless steel metal flexible pipe, comprise crest and the trough soft net of cylindrical metal that is woven into by wire of the stainless steel metal bellows of moulding and overcoat thereof alternately mutually, it is characterized in that: the cross section is contained in the top of bellows for the π type ring set that moves about, the soft net end of metal is installed in the stainless steel metal bellows and moves about interannular, the stainless steel metal bellows, the soft net of metal and the boxing of moving about connect fixing, two flanges are sleeved on stainless steel metal bellows two ends, move about between the ring two, free to rotate.
Described stainless steel metal bellows is spirality or Ω shape.
Described stainless steel metal bellows adopts SUS304 or SUS316L stainless steel material.
The soft net of described metal is the soft net of stainless steel metal.
Described stainless steel metal bellows is 15mm, 20mm, 25mm, 32mm, 40mm, 50mm, 65mm, 80mm, a 100mm9 latus rectum, random lengths.
The described ring that moves about adopts the SUS304 stainless steel material.
The beneficial effects of the utility model are:
1, have only 4 component to constitute owing to comprise bellows and soft net, it is the simplest that structural type reaches, and the cost of product reaches minimum.
2, because the stainless steel metal bellows adopts spirality and Ω type, resistance to pressure that it is good and ductility are improved cost performance of product.
3, owing to adopt the Connecting format of lap joint flange, can be connected with client's pipeline very easily, simultaneously, can match the flange of various standards neatly, as: the flange of standards such as ANSI, JIS, GB.
4, owing to adopted the mode that is flexible coupling of stainless steel metal bellows, allow the on-the-spot pipe arrangement of various pipelines become simply, improved working efficiency greatly.
5, because the ring that moves about adopts the manufacturing of SUS304 material to form, the contact segment of fluid is stainless steel metal bellows and the stainless steel ring that moves about, fluid in the pipe does not contact with the flange that carbon steel is made, therefore, be applicable to that great majority need the occasion of all steel structure hose coupling, avoid the expensive of all steel structure, reached low cost and high reliability.
6, owing to adopt spirality and Ω shape metal bellows, the helical fissure pipe adopts the processing of high-speed and continuous molding mode, has further reduced cost of production; High pressure resistant, the high temperature of Ω type metal bellows excellence, corrosion resistance make it than other joint that is flexible coupling as types such as rubber pipes, have purposes widely, have more promotional value.
