Abstract
A sea water conveying pipelines in marine climate is characterized by comprising a flange, a seamless steel pipe, a rubber liner, japanning, a gasket, an isolation sleeve, an isolation gasket and a connecting fastener, wherein the flange is in butt joint welding with the seamless steel pipe, rubber lining is performed on the inner walls of the pipelines and a sealing end face, the two pipelines are connected by means of flange connection. Connecting parts comprise the gasket, the isolation sleeve, the isolation gasket and the connecting fastener. Sea water conveying pipelines in the marine climate have the advantages of being excellent in structure, high in strength and anti-impact performance, good in rigidity, free of creep deformation, resistant to vibration, strong in resistance to water hammer, convenient to transport, install and maintain, wide in temperature application range, capable of saving energy, good in lubricating performance, small in operation resistance loss, capable of saving operation cost, excellent in aging resistance, low in cost, short in manufacture cycle and capable of ensuring construction period. In addition, sea water conveying pipelines in marine climate have the common advantages of steel pipes and abrasion-resistance rubber, thereby being remarkable in comprehensive performance to price ratio.
Description
Technical field
The utility model relates to the seawater conveyance conduit under the ocean climate, common working pressure≤1.0MPa, and medium temperature is applied in fields such as nuclear power, thermoelectricity in-40 ℃ ~ 75 ℃ scopes.
Background technique
The seawater conveyance conduit mainly contains 316L, two-way stainless steel 2205, plastic tube and carbon steel line with rubber pipeline at present.
Preceding two kinds under the condition of no cathode protection measure, long-time corrosion easily, and contain under the condition of water quality of sand, rubbish equal difference at seawater; Fluid is under the effect of speed; Be easy to generate wearing and tearing, so 316L and two-way stainless steel 2205 pipelines cost an arm and a leg, working life is short.
Though the plastic pipe price is relatively low, have quick stress cracking phenomenon, and this phenomenon is difficult to overcome.
Summary of the invention
The purpose of the utility model is in order to improve working life, and the spy provides the conveyance conduit of the seawater under a kind of ocean climate.
The utility model provides the conveyance conduit of the seawater under a kind of ocean climate, it is characterized in that: the seawater conveyance conduit under the described ocean climate comprises flange 1, seamless steel pipe 2, line with rubber 3, japanning 4, pad 5, separation sleeve 6, spacer ring 7, connects fastening piece 8;
Wherein: pipeline adopts to dock with seamless steel pipe 2 through flange 1 and is welded, and carries out line with rubber at inner-walls of duct and seal face, and two pipelines connect through the flange ways of connecting, union piece: pad 5, separation sleeve 6, spacer ring 7, connection fastening piece 8.
It is described that to carry out line with rubber at inner-walls of duct and seal face be the 4mm neoprene.
Described flange 1 end face has 4mm to sink, line with rubber end face and flange 1 end face, and when flange connected, pad 5 was realized sealing.
Described connection fastening piece 8 adopts the 316L stainless steel
Described stainless steel support 8 screw thread places are coated with the Dur1305 rust resisting compound, avoid the stainless steel support deadlock phenomenon, guarantee that dismounting is free.
The advantage of the utility model:
1) structure is good
The enhancing skeleton steel pipe of tubing and rubber layer use high performance tackiness agent compound as a whole; It is withstand voltage not wear-resisting to have overcome steel pipe; Plastics, rubber wear-resisting are not withstand voltage and shortcoming such as the crisp shock resistance difference of glass fibre reinforced plastics; The common advantage that possesses steel pipe and abrasive rubber simultaneously, comprehensive price ratio is remarkable.
2) intensity is high, and impact resistance is high
The density of rubber elastomer is low, and is in light weight, has absorbing performance preferably and excellent anti-mechanical shock performance, high tenacity, and good rigidly does not produce creep, shock resistance, antidetonation, anti-water hammer performance is strong, is convenient to transportation, installation and maintenance.
3) temperature wide accommodation
Neoprene line with rubber pipeline can use in the scope of-40 ° of C～+ 75 ° C for a long time, and the line with rubber layer can not thrown off because of temperature variation and steelframe.
4) energy-conservation
Lubricity is good, and the running resistance loss is little, saves operating cost.
5) aging quality resistance is superior
Reach more than 15 years general working life under normal working pressure temperature.After pipeline uses 6-8 nearly 90 ° of rotations once, working life can be longer, line with rubber pipeline line with rubber repeatedly uses 4 times, reduces cost, fabrication cycle is short, can guarantee the duration.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is done further detailed explanation:
Fig. 1 is the line with rubber piping drawing;
Fig. 2 is the flange connection diagram.
