Abstract
The utility model discloses a be able to bear or endure compound pipe of high compression moulding material with burying, including the steel pipe body, be equipped with polyvinyl chloride plastic -coated layer on the inner wall of steel pipe body the last composite plastic film layer that is equipped with of plastic -coated layer, the glass fiber layer that is equipped with on the steel pipe body outer wall, the glass fiber layer forms for the winding of glass fiber net cloth, be equipped with the ultrahigh molecular weight polyethylene layer outside the glass fiber layer, the utility model has the advantages of: it is good to connect the leakproofness, and connection structure intensity is higher, and is corrosion -resistant, and the ageing resistance has prolonged life, has improved product quality.
Description
Technical field
This utility model relates to a kind of composite pipe, a kind of buried high pressure resistant plastic composite pipe, belongs to composite pipe field.
Background technology
Steel-plastics composite pipe has stronger external force resistance destructive characteristics, is effectively improved the service life of pipeline, and extend pipeline is excused from a college course the phase, decreases the leakage of pipeline.Steel-plastics composite pipe is the favorable substitutes of steel conduit and nonmetal pipeline, has broad application prospects at the aspect such as oil-gas gathering and transportation and sewage transport.The Chinese utility model patent of entitled " a kind of plastic coated composite steel pipe " Application No. " 201420121898.3 " discloses a kind of plastic coated composite steel pipe, including steel pipe body, the inner wall surface of described steel pipe body is provided with ultra-high molecular weight polyethylene undercoating, the outer wall surface of described steel pipe body is provided with ultra-high molecular weight polyethylene external coating, the two ends of described steel pipe body are provided with stainless joint, the internally coated thickness of described ultra-high molecular weight polyethylene is 0.4-1mm, and the thickness of described ultra-high molecular weight polyethylene external coating is 0.65-1mm.But, the connection sealing of this product is poor, and attachment structure intensity is relatively low, and inside and outside wall is the most damaged, and antiageing effect is poor, reduces service life.
Utility model content
In order to solve the problems referred to above, this utility model devises a kind of buried high pressure resistant plastic composite pipe, and connection sealing is good, and attachment structure intensity is higher, corrosion-resistant, and aging resistance extends service life, improves product quality.
The technical solution of the utility model is:
A kind of buried high pressure resistant plastic composite pipe, including steel pipe body, the inwall of described steel pipe body is provided with polrvinyl chloride coating layer, is provided with compound plastic film layer on described coating layer；Preferably, described compound plastic film layer is the PE plastic sheeting being solidificated on described coating layer, compound plastic film layer is in addition to combining with body layer, coating layer and bearing the hydraulic pressure stress with minimizing tubing, the deflection of tubing can also be reduced, owing to the elasticity of compound plastic film layer is better than coating layer, when tubing is by hydraulic pressure effect, as tiny eyelet and crack occurs in coating layer, compound plastic film layer can prevent from therefore producing the problem of infiltration, and after compound plastic film, inside pipe wall is smooth, frictional resistance is little, and linear loss during water delivery is little；The glass layer that described steel pipe body outer wall is provided with, described glass layer is that fiberglass gridding cloth is entwined, and described glass layer is externally provided with ultra-high molecular weight polyethylene layer, extends service life further.
Further, the end of described steel pipe body is provided with adpting flange, anticorrosion flange it is provided with outside described adpting flange, clamping it is provided with protruding on described adpting flange outer face, suitable clamping groove protruding with described clamping it is provided with on the seal face of described anticorrosion flange, described adpting flange is installed on the seal face of described anticorrosion flange by the protruding and described clamping groove of described clamping, described adpting flange is structure as a whole with described steel pipe body, described anticorrosion flange is ultra-high molecular weight polyethylene structure, it is achieved thereby that seal and anticorrosion ability.
Further, the inner surface of described steel pipe body is provided with some grooves and projection, improves the being firmly combined with property of steel pipe body and polrvinyl chloride coating layer, it is to avoid lamination occurs after using a period of time, extends service life.
It addition, be additionally provided with epoxy layer and ASA coating between described glass layer and described ultra-high molecular weight polyethylene layer；Described epoxy layer is epoxy resin, and described epoxy layer is located between ASA coating and glass fibre, can operation at bad environments, and length in service life, serviceability are good.
The utility model has the advantage of: connection sealing is good, attachment structure intensity is higher, corrosion-resistant, and aging resistance extends service life, improves product quality.
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
