Abstract
The utility model provides a kind of plastic coated composite steel pipe, comprise 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.The beneficial effects of the utility model arrange ultra-high molecular weight polyethylene coating at the inside and outside wall of steel pipe body, the premium properties of set two kinds of tubing, plastic coated composite steel pipe is made to have excellent wear-resistant, decay resistance, and its compressive strength is high, strong shock resistance, substantially prolongs the working life of pipeline.
Description
Technical field
The utility model belongs to tubing field, especially relates to a kind of plastic coated composite steel pipe.
Background technique
The steel-plastic composite pipe with good antiseptic property is 4 ~ 5 times of common steel tube working life, compared with the nonmetal pipelines such as glass fibre reinforced plastics, there is stronger external force resistance destructive characteristics, effectively improve the working life of pipeline, what extend pipeline is excused from a college course the phase, decreases the leakage of pipeline.Ultra-high molecular weight polyethylene is a kind of thermoplastic engineering plastic with Good All-around Property of linear structure, has the performances such as shock-resistant, wear-resistant, the self lubricity of the unrivaled excellence of other plastics, resistance to chemical attack because its molecular weight is higher.Therefore, steel-plastic composite pipe is the favorable substitutes of steel pipeline and nonmetal pipeline, has broad application prospects in oil-gas gathering and transportation and sewage transport etc.
Model utility content
The purpose of this utility model is to provide a kind of corrosion-resistant, anti abrasive plastic coated composite steel pipe.
The technical solution of the utility model is: a kind of plastic coated composite steel pipe, comprise 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, ultra-high molecular weight polyethylene is sprayed at equably on the inner and outer wall of described steel pipe body, forms ultra-high molecular weight polyethylene undercoating and ultra-high molecular weight polyethylene external coating.
Further, the internally coated thickness of described ultra-high molecular weight polyethylene is 0.4-1mm.
Further, the thickness of described ultra-high molecular weight polyethylene external coating is 0.65-1mm.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, at the inside and outside wall of steel pipe body, ultra-high molecular weight polyethylene coating is set, the premium properties of set two kinds of tubing, make full use of the characteristic of ultra-high molecular weight polyethylene, make plastic coated composite steel pipe have excellent wear-resistant, decay resistance, and its compressive strength is high, strong shock resistance, stainless joint itself has corrosion-resistant characteristic, and pipeline is easy to connect, substantially prolongs the working life of pipeline.
