UPVC pipe is a new type of plastic pipe, polyvinyl chloride resin as raw material, with the performance of PVC in general, in terms of performance has improved, special envoy and suitable for water supply official website. Despite its obvious advantages, it is not perfect, there are still some defects. For example, the temperature of the UPVC tube has a certain impact, the following, to look at the specific impact.
Heat resistance of UPVC pipe is relatively poor, in more than 60 degrees Celsius environment, the tensile strength decreased, so the design should be away from heat, hot water pipe insulation measures should be taken, not through the flue and the firewall.
Because of the influence of temperature, expansion coefficient, each layer of the vertical tube and long horizontal tube to set expansion joints, thus, other professional arrangement should be considered when the notch effect of UPVC tube, and other plastic pipe laying flat pipe, laying aside, when the cross, in the plastic pipe and should be staggered and, consider adding metal casing protection.
UPVC tube is not easy to be acid because it is not conductive. Alkali. An electrochemical reaction occurs in the salt. Alkali. It is difficult to corrode it, so it does not need external corrosion protection coating and lining. The utility model has the advantages of good flexibility and overcomes the disadvantage of the brittleness of the plastic pipe in the past.
