Abstract
The utility model discloses a compound pipe of high corrosion -resistant plastic -coated of intensity, including the steel pipe body, the internal and external surface of steel pipe body all is equipped with the zinc -nickel electroplating alloy coating, is located the outside the surface of zinc -nickel electroplating alloy coating is equipped with the glass fiber layer, the glass fiber layer forms for the winding of glass fiber net cloth, be located the inboard the internal surface of zinc -nickel electroplating alloy coating is equipped with the ultrahigh molecular weight polyethylene undercoating, the utility model has the advantages of: intensity is high, and corrosion -resistant, the ageing resistance has prolonged life, has improved product quality.
Description
Technical field
This utility model relates to a kind of composite pipe, specifically a kind of intensity highly corrosion resistant plastic-coated 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, this product 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 intensity highly corrosion resistant plastic-coated composite pipe, and intensity is high, corrosion-resistant, and aging resistance extends service life, improves product quality.
The technical solution of the utility model is:
A kind of intensity highly corrosion resistant plastic-coated composite pipe, including steel pipe body, the surfaces externally and internally of described steel pipe body is equipped with zinc-nickel alloy coating, there is the corrosion resistance of excellence, corrosion resistance is 2-4 times of hot dip galvanizing pipe, and the outer surface of the described zinc-nickel alloy coating being positioned at outside is provided with glass layer, and described glass layer is that fiberglass gridding cloth is entwined, so that product has higher structural strength, and anticorrosion effect is good；The inner surface of the described zinc-nickel alloy coating being positioned at inner side is provided with ultra-high molecular weight polyethylene undercoating, further increases wear-resistant, the decay resistance of product.
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, and described anticorrosion flange is ultra-high molecular weight polyethylene structure, it is achieved thereby that seal and anticorrosion ability.
Further, described clamping projection is the forked tail platform that outer imperial palace is little that is projected as in its cross section, described clamping groove be the projection in its cross section suitable with described forked tail platform in greatly the least dovetail groove.
It addition, be additionally provided with epoxy layer and ASA coating between described steel pipe body and described glass layer；Described epoxy layer is epoxy resin, and described epoxy layer is located between ASA coating and steel pipe body, can operation at bad environments, and length in service life, serviceability are good.
The utility model has the advantage of: intensity is high, corrosion-resistant, 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.
