Abstract
Disclosed is a composite soft tube suitable for ocean heat preservation mixed transportation. The composite soft tube is composed of a frame layer, a lining layer, a pressure-bearing armor layer, a wear-resistant layer, a pulling-bearing armor layer, a heat preservation layer, a middle protection layer, an armor protection layer and a protection layer. Stainless steel serves as the base material of the frame layer, and a continuous interlocking structure is formed by six rolling forming molds through combined action. The lining layer, the middle protection layer and the protection layer are formed through thermoplastic plastic in a cooling mode, wherein the thermoplastic plastic is formed by a squeezing machine in a continuous squeezing mode. The pressure-bearing armor layer, the pulling-bearing armor layer and the armor protection layer are wound around a pipe body by pressure-bearing steel strips and pulling-bearing flat steel respectively through specific winding equipment provided with a wrapping machine set, and a wear-resistant strip can be wound between the pressure-bearing armor layer and the pulling-bearing armor layer to form a wear-resistant layer. A heat preservation strip is of a strip-shaped structure formed by a polypropylene base body with vacuum glass beads as dispersion phases scattered and is wound between the pressure-bearing armor layer and the middle protection layer to form the heat preservation layer.
Description
Technical field
What the present invention relates to is the structural type of a kind of ocean composite soft tube, particularly a kind of innovation with the mixed defeated composite hose structure of heat insulation function.Belong to ocean engineering field.
Background technique
Pipeline under the ocean traditional, routine be take steel pipe as main, whole construction, installation and follow-up maintenance work cycle, long expense was high, the steel that Abroad in Recent Years rises mould composite soft tube because anticorrosive property is good, submarine topography landforms strong adaptability, laying speed is fast, expense is low, be difficult for wax deposition and the conveying that advantage starts to be applied to seabed oil, G&W such as can reuse comes up.But external sea multiphase pipeline complex structure and installation cost are higher, and domestic flexible pipe is still in the starting stage, and product function and structure are more single, just start to be applied in the oil transportation that water delivery, gas transmission and conveying solidifying point are higher.Along with the exploitation of deepwater field, medium composition to be conveyed and applying working condition complexity is more the insulation that the solidifying point that has need to be considered pipeline when lower, to guarantee there will not be solidifying pipe phenomenon at the terminal medium of carrying in mixed defeated medium.Therefore the flexible pipe if do not adopted with insulating structure, can only significantly improve the temperature of pipeline import, and the raw material selection expense and the auxiliary facility expense that produce very high tubing significantly improve.
Present patent application has proposed a kind ofly can effectively solve the mixed defeated composite soft tube of insulation that may occur the phenomenon of solidifying pipe due to fed sheet of a media solidifying point when lower just under this background.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of ocean heat preservation that is applicable to mix defeated composite soft tube, it can carry out in oil, gas, water mixed delivery process at submerged pipeline, the solidifying pipe phenomenon that reduction causes temperature drop to cause due to the thermal loss of body, and can effectively reduce because not adopting thermal insulation layer to use Thermostable flexible hose instead, improving the high cost that inlet temperature produces.
The technological scheme that technical solution problem of the present invention adopts is, a kind of be applicable to the mixed defeated composite soft tube of ocean heat preservation from inside to outside successively by framework layer, inside liner, pressure-bearing armor, wearing layer, bear armor, thermal insulation layer, intermediate protective layer, armored protective layer, protective layer and form.Wherein framework layer is by stainless steel as base material, and under the effect of 6 pairs of forming rolls of cingulum machine equipment, rolling forms the profiled strip of S shape, and the mold acting in conjunction by 6 rolling and formings forms continuous interlocking structure; Inside liner, intermediate protective layer and protective layer are formed through cooling forming by the continuous extrusioning thermoplastic plastic of extruder; Pressure-bearing armor, bear armor and armour protective layer respectively by pressure-bearing steel band with bear band steel and be wrapped on body by special winding equipment, Wiring apparatus is supporting wrapped unit, banded wear-resistant strip can be wrapped in to pressure-bearing armor and bear between form wearing layer; Insulation belt is dispersed in a kind of banded structure in polypropylene matrix by vacuum glass microballon as dispersed phase; and be wrapped in and bear between armor and intermediate protective layer; form thermal insulation layer; it is a kind of continuous structure in body inside; by the total heat-transfer coefficient of self lower thermal conductivity reduction flexible pipe, reach the effect of insulation.
Beneficial effect of the present invention: the present invention can carry out in oil, gas, water mixed delivery process at submerged pipeline, the solidifying pipe phenomenon that reduction causes temperature drop to cause due to the thermal loss of body, and can effectively reduce because not adopting thermal insulation layer to use Thermostable flexible hose instead, improving the high cost that inlet temperature produces.
