Description

A kind of Novel corrosion-resistant heat-preserving pipe

Technical field

This utility model relates to a kind of insulating tube, particularly a kind of Novel corrosion-resistant heat-preserving pipe.

Background technology

Utilidor is widely used in liquid, transfer of gas pipe network, chemical pipeline heat insulating work oil, Chemical industry, central heating network, ventilating duct of central air conditioner, municipal works etc..When construction, need First to lay anti-corrosion pipe, the outer surface in anti-corrosion pipe arranges heat-preservation cotton the most again, installation effectiveness is low, Take people laborious, and, its outside heat-preservation cotton of the insulating tube of this kind of structure is easily by external environment condition Affect and damage, reduction of service life.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one has design department Reasonable, conveniently install, insulation antiseptic is effective, the Novel corrosion-resistant heat-preserving pipe of length in service life.

This utility model solves it and technical problem is that and take techniques below scheme to realize:

A kind of Novel corrosion-resistant heat-preserving pipe, including steel pipe body, it is characterised in that: also include lining plastic Layer, outer plastic lining layer and foaming layer, arrange lining plastic layer, in institute on the inwall of described steel pipe body The outside stating steel pipe body arranges outer plastic lining layer, is provided with and sends out between steel pipe body and outer plastic lining layer Alveolar layer.

And, described outer plastic lining layer is by moulding layer body and spiral helicine guide rib is constituted, this guide Rib with mould a layer body injection moulding integrated molding, described guide rib is formed on the inner surface moulding layer body, The space that guide rib and steel pipe body are formed becomes walks material space.

Advantage of the present utility model and good effect be:

1. this Novel corrosion-resistant heat-preserving pipe, is moulded by the interior outer lining at original steel pipe, enhances its anti-corrosive properties Can, the foaming with heat insulation function is suppressed between steel pipe and outer plastic lining layer simultaneously, ensure that While heat insulation function, protect the heat-insulation layer destruction from the external world, extend this anti-corrosive and thermal insulation pipe Service life；It addition, this there is anticorrosion, the pipeline of heat insulation function is a complete product, execute Man-hour can directly lay, and the most individually does the operation being incubated before eliminating, and makes efficiency of construction significantly carry High.

2. this Novel corrosion-resistant heat-preserving pipe, by the setting of guide rib on outer plastic lining layer inwall, sends out filling During bubble, foaming can be filled with along the guiding of helical form guide rib, thus ensures foam filled Uniformly, it is ensured that heat-insulating property；It addition, guide rib also has the effect of support frame, prevent outer lining Mould layer to deform.

3. this utility model scientific structure design is reasonable, has convenient installation, improves efficiency of construction, guarantor Temperature favorable anti-corrosion effect, the advantage of length in service life, be a kind of novel anticorrosion with higher innovation Insulating tube.

Fig. 2 is the structural representation (sectional view) of the outer plastic lining layer of this utility model.

Description of reference numerals:

The outer plastic lining layer of 1-, 2-foaming layer, 3-steel pipe body, 4-lining plastic layer, 5-guide rib, 6-walk Material space.

Detailed description of the invention

Below in conjunction with the accompanying drawings, by specific embodiment, the utility model is described in further detail.Following reality It is illustrative for executing example, is not determinate, it is impossible to limit protection model of the present utility model with this Enclose.

A kind of Novel corrosion-resistant heat-preserving pipe, including steel pipe body 3, its innovation is: in also including Plastic lining layer 4, outer plastic lining layer 1 and foaming layer 2, arrange lining plastic on the inwall of described steel pipe body Layer, arranges outer plastic lining layer in the outside of described steel pipe body, between steel pipe body and outer plastic lining layer It is provided with foaming layer.

Described outer plastic lining layer by moulding layer body and spiral helicine guide rib 5 is constituted, this guide rib with Moulding a layer body injection moulding integrated molding, described guide rib is formed on the inner surface moulding layer body, guide The space that rib and steel pipe body are formed becomes walks material space 6.

This utility model is moulded by the interior outer lining at original steel pipe, enhances its antiseptic property, simultaneously The foaming with heat insulation function is suppressed between steel pipe and outer plastic lining layer, ensure that heat insulation function While, protect the heat-insulation layer destruction from the external world, extend the service life of this anti-corrosive and thermal insulation pipe； It addition, this there is anticorrosion, the pipeline of heat insulation function is a complete product, can be direct during construction Lay, the most individually do the operation being incubated before eliminating, make efficiency of construction be greatly improved.By outward The setting of guide rib on plastic lining layer inwall, when filling-foam, foaming can be along helical form guide The guiding of rib is filled with, thus ensure foam filled uniformly, it is ensured that heat-insulating property；It addition, lead Material rib also has the effect of support frame, prevents outer plastic lining layer from deforming.

Although disclosing embodiment of the present utility model and accompanying drawing for the purpose of illustration, but this area Those of skill will appreciate that: without departing from this utility model and spirit and scope of the appended claims In, various replacements, to change and modifications be all possible, therefore, and scope of the present utility model not office It is limited to embodiment and accompanying drawing disclosure of that.
