One is incubated adiabatic tubing under water

Technical field

The utility model relates to tubing technical field, particularly relates to one and is incubated adiabatic tubing under water.

Background technique

Need insulation adiabatic when laying conveying crude oil, water, chemical medium in the environment such as ocean, rivers, lake and quagmire, the one of heat-insulation material under water of current use is steel pipe, as shown in Figure 1, usually the structure of polyurethane foamed thermal-insulating layer 5 and high density polyethylene (HDPE) jacket tube 6 is adopted successively at steel pipe 4 outer surface, the external and internal compositions of this kind of tubing is not compact, waterproof outer material is easy damaged when constructing, cause thermal insulation layer to be intake to lose efficacy, shorten the life-span of tubing, and heat insulation effect also has much room for improvement.

Another kind directly carries out underwater fluid conveying by PE, PERT, HDPE, PPR or PVC, and this kind of tubing insulation adiabatic coefficient is on the low side, and insulation insulation effect is bad, and thermal conductivity is comparatively large, and heat loss is larger.

Existing tubing, no matter adopt metal material, plastic material or other are compound, its thermal insulation property is all undesirable, in course of conveying, medium easily and external environment carry out exchange heat, thus affecting the stability of medium temperature, the final result caused therefrom is the waste of the loss of energy, resource.

Model utility content

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides one to be incubated adiabatic tubing under water, when medium is carried in tubing, reaches good heat insulation effect and sealing effect, falls low-energy loss, realize the object of energy-conserving and environment-protective.

To achieve these goals, the technical solution adopted in the utility model is as follows:

One is incubated adiabatic tubing under water, it comprises body, described body is hollow tubular, described body comprises internal layer, mesosphere and skin, described internal layer is high-density and high-temperature-resistant polythene material tube layer, and described mesosphere is hollow glass microbead filled thermal insulation materials layer, and described skin is high density corrosion protection polythene material tube layer, described mesosphere and described internal layer and described outer compact siro spinning technology, the three layers of formula structure that is combined into one.

Wherein, described hollow glass microbead filled thermal insulation materials layer is the tube layer joined as additive by hollow glass microbead in PE material.
