| titleOfInvention | Water supply plastic-coated composite steel pipe with good weather resistance |
| abstract | The utility model discloses a water supply plastic-coated composite steel pipe with good weather resistance, which comprises a steel pipe body, wherein the inner surface of the steel pipe body is provided with a pressure-resistant layer, the inner surface of the pressure-resistant layer is provided with a polyethylene coating, and the outer surface of the pressure-resistant layer is provided with a composite base layer; the water supply plastic-coated composite steel pipe with good weather resistance is provided with the first polymeric fiber layer, the second polymeric fiber layer and the outer zinc coating layer, so that the response effect of expansion with heat and contraction with cold of a steel body can be achieved, the crystal cleaning degree and the structural toughness of the pipe structure are improved, and the stable weather resistance and the environmental adaptability of the steel pipe body are improved; through setting up compressive layer, polyethylene coating, outer galvanizing coat, hydrophobic granule and hydrophobic layer, can reach good acidproof, alkali-proof, hydrophobic, shock resistance and anticorrosion effect to the steel pipe body to this effectual ageing resistance that improves steel pipe body structure has realized the inside and outside quality of steel pipe body product, has more prolonged the life of steel pipe body. |
