UPVC管道的对温度的特点

UPVC管是一种新型的塑料管材,是以聚氯乙烯树脂为原料的,具备一般聚氯乙烯的性能,在性能上又有所提升,特使适和用于供水官网。其尽管优点十分显著,但并不是十全十美的,仍然存在一些缺陷的。就比如温度对UPVC管有一定的影响,下面,就来看看具体的影响。

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.

UPVC管的耐热性是比较差的,在60摄氏度以上的环境下,抗拉强度下降,所以设计使用中应该远离热源,同时热水管道应采取保温措施,不能穿越烟道和防火墙。

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.

因为受到温度的影响大,膨胀系数大,每层立管及较长的横管上要设置伸缩节,由此,其他专业布置时应考虑UPVC管的缺口效应,在与其他管道平型敷设时,塑料管靠边,当交叉敷设时,塑料管在下且应错开,并考虑加金属套管防护。

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管因为它不导电,因而不容易与酸。碱。盐发生电化学反应,所以酸。碱。盐都难于腐蚀它,所以不需要外防腐涂层和内衬。而柔软性好这又克服了过去塑料管脆性的缺点,在荷载作用下能产生屈服而不发生破裂。

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.
