Description
Technical field
The present invention relates to a kind of various water, gas, oil-piping flanged joint and preparation method thereof, especially relate to a kind of non-welding flange connected omega type non-corrodible steel metal hose and making method.
Background technique
As everyone knows, along with being flexible coupling of being made up of parts such as flange-connection stainless steel metal flexible pipes obtains continuous extensive use in various pipe-line systems, flexible and efficient pipeline construction, solve displacement that a variety of causes of pipeline causes, solve various requirement such as Corrosion of Pipeline and 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, and in the hope of reaching erosion-resisting purpose, have caused unnecessary waste.Simultaneously, also caused the whole tubing construction cost to increase.
At present, a lot of producers all adopt welding manner to make the metallic hose assembly, during welding, to produce the heat affected zone in the certain zone around the welding bead, when this regional temperature surpasses about 780 degrees centigrade, the lattice tissue of Austenitic Stainless Steel will transform, be converted into ferrite+pearlite, its corrosion resistance descends, and is needing the high occasion of corrosion resistance or under certain particular environment, this zone is easy to be corroded and leaks.
Now, domestic most of producers can only produce U type bellows because process equipment and processing technology are more backward, as the body of hose coupling, make metal hose joint, and the withstand voltage properties of the U type metal bellows of same thickness of pipe wall is lower than Ω type metal bellows.Its ductility of U type metal bellows also is lower than Ω type metal bellows.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of non-welding flange connected omega type non-corrodible steel metal hose and making method are provided, it has ductility, resistance to pressure than U type bellows, can satisfy the pressure rating requirement, thereby, the cost of reduction pipework; Use short Ω type metal bellows can solve bigger displacement; Thereby reach the purpose of saving, the supporting use of preferably and existing body.
The present invention is achieved by the following technical solutions: a kind of non-welding flange connected omega type non-corrodible steel metal hose, 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 stainless steel metal bellows is the Ω type, two semicircle clamp rings snap at least from the three trough of corrugated tube port number, the soft net of metal is fixed, the net pressing ring cross section is L shaped, the soft net spiral-lock of the clamp ring of two semicircles and metal is in net pressing ring L type groove, remaining at least two crests of corrugated tube port are compressed to a sealing surface, two flange plates are sleeved on the flange-connection stainless steel metal flexible pipe outside, free to rotate, between two sealing surfaces.
A kind of non-welding flange connected omega type non-corrodible steel metal hose making method adopts non-welded structure form, and typical lap joint flange Placement is adopted at two ends, may further comprise the steps:
1, the stainless steel sheet material is become the stainless steel straight tube through welding of longitudinal seam, as pipe;
2, the stainless steel straight tube takes mechanical swelling continuously shaped for Ω type metal bellows;
3, along the circumferential direction cut off at the trough place by certain-length;
4, two semi-circular clamp rings are snapped in from least the three trough of port number;
5, be inserted in the soft net of metal, be inserted in the net pressing ring that the cross section is the L type again, the clamp ring and the soft net spiral-lock of metal of two semicircles are gone in the groove of net pressing ring L type prestressing, clamp ring, the soft net of metal and net pressing ring are welded together, and bellows and above-mentioned parts do not weld;
6, will be from bellows one port to remaining at least two crests the clamp ring, machinery is flattened into certain thickness, keeps the pressing ripple that certain flexible sealing surface is arranged;
7, the other end from bellows is inserted in two flange plates, and this flange plate is free to rotate;
8, in the three trough of the other end of bellows, snap in two semi-circular clamp rings in addition at least, be inserted in the net pressing ring that the cross section is the L type afterwards again, the soft net spiral-lock of the clamp ring of two semicircles and metal is gone in the groove of net pressing ring L type, prestressing, clamp ring, the soft net of metal and cross section L type net pressing ring are welded together, and bellows and above-mentioned parts do not weld; Will be from this port at least two crests of the residue the clamp ring, machinery is flattened into certain thickness, keeps the pressing ripple that certain flexible end face is arranged; The end face of this part bellows crops the soft net of two ends excess metal as the sealing surface of product.
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 can be made 20mm, 25mm, 32mm, 40mm, 50mm, 65mm, 80mm, 100mm, 125mm, 150mm, 200mm, 250mm12 kind latus rectum, random lengths.
The invention has the beneficial effects as follows:
1, owing to adopt non-welded structure, well solved owing to the localized heat influence of welding, thereby the corrosion resistance and the vibration strength of product had a negative impact Stainless Steel Flexible Hose and the generation of stainless steel soft net.Therefore, be adapted at using under the vibrations occasion of some typical high frequency low-amplitudes, as: the connection of outlet such as water pump, air compressor.
2, because flange-connection stainless steel metal flexible pipe adopts Ω type metal bellows, resistance to pressure that it is good and ductility are improved cost performance of product, under identical service condition, make pipework can save investment.
3, owing to adopt the connection pattern of overlapping flange while still alive, can be connected with client's pipeline very easily, simultaneously, can match the flange of various standards flexibly, 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 contact segment of its fluid is the body of Ω type metal bellows, the fluid in the pipe does not contact with other component.Therefore, in most application, other component except that bellows and soft net all can adopt straight carbon steel.Avoid the expensive of all steel structure, reached low cost and high reliability.
6, owing to adopt Ω type metal bellows, high pressure resistant, the high temperature of its excellence, corrosion resistance make it than other joint that is flexible coupling as types such as rubber pipes, have purposes widely.
