Abstract
The utility model relates to a fluid composite pipe for the transport of liquid and gas. Wherein, two ends of the metal corrugated pipe are respectively assembled with one end of the connecting pipe and are fixedly connected in a sealing way, a metal protecting pipe is sleeved outside the metal corrugated pipe, and the other end of the connecting pipe is respectively fixedly connected with two ends of the metal protecting pipe in a sealing way; the two ends of the metal protection pipe are provided with pipe joints. The utility model discloses the fluid composite pipe compares with exclusive use corrugated metal pipe, and life extension is a lot, has reduced the maintenance duration of equipment, especially is arranged in enterprises such as metallurgy and petrochemical, has reduced manufacturing cost, has certain economic benefits.
Description
Technical field
The utility model relates to a kind of fluid composite pipe, is used for the conveying of liquids and gases.
Background technique
Make the delivery element of liquids and gases with metal bellows, engineering and daily giving birth in the words early to be extensive use of, it has Placement flexibly, but in some specific Environmental Conditions, on the equipment in metallurgical and the petrochemical enterprise, because the tube wall of common metal bellows is thinner, so be easy to be subjected to acid and alkali corrosion and rugged environment to influence, bellows is damaged easily, and working life is very low.Thereby cause production accident, influence is produced and economic benefit.
The model utility content
In order to overcome the defective of prior art, the utility model provides a kind of fluid composite pipe of long service life.
The utility model fluid composite pipe, comprise metal bellows, wherein the metal bellows two ends are equipped with connecting tube one end respectively, and are sealedly connected and fixed, at wavy metal tube outside suit one protection metal pipe, the other end of connecting tube is connected and fixed with protection metal pipe is sealed at both ends respectively; The protection metal pipe two ends are provided with pipe joint.
The utility model fluid composite pipe is wherein opened an aperture on the middle tube wall of connecting tube at least, is communicated with gap between metal bellows and the protection metal pipe.
The utility model fluid composite pipe, wherein metal bellows is a corrugated stainless steel tubing, protection metal pipe is a Stainless Steel Tube.
The utility model fluid composite pipe, wherein connecting tube is passed with metal bar and the metal bellows two ends are fixed with the welding of metal coating inner tube wall in two ends in the protection metal pipe.
The utility model fluid composite pipe is compared with independent use metal bellows, just prolongs much with the life-span, has reduced the engineering time of equipment, in enterprises such as metallurgical and petrochemical industry, has reduced cost of production, has certain economic benefits.
Description of drawings
Fig. 1 is a structural profile schematic representation of the present utility model.
Embodiment
As seen from Figure 1, the utility model fluid composite pipe comprises stainless steel metal bellows 1, protection metal pipe 2, metal connecting tube 3 and metallic pipe coupling 5.Corrugated stainless steel tubing 1 two ends are fixed with metal connecting tube 3 one end seal weldings respectively, and at corrugated stainless steel tubing 1 outside set metal protective tube 2, the not saturating corrugated steel pipe 1 of protection is not subject to acid and alkali corrosion and rugged environment influence, damages bellows; The other end of metal connecting tube 3 is fixed with protection metal pipe 2 sealed at both ends welding respectively; Protection metal pipe 2 two ends are connected with flanged joint 5, are convenient to be connected with other parts.Have aperture 4 on the middle tube wall of metal connecting tube 3, it is communicated with gap between corrugated stainless steel tubing 1 and the protection metal pipe 2, can the balance tube internal pressure.
Corrugated stainless steel tubing 1 can be the bellows of other metallic material in the present embodiment.
Protection metal pipe 2 can be a straight tube, also can be bend pipe.
The metallic pipe coupling 5 at protection metal pipe 2 two ends can be multiple structural type, is applicable to different Placements.
The diameter and the length of fluid composite pipe of the present utility model are not limit.
