河北PVC给水管厂

In the drainage system of the new project, the situation and frequency of the PVC drainage pipe appear more and more, and more and more attention is paid to it. For example, what size and model are used in common use? Although PVC drainpipes have been popularized in various projects, many of their knowledge remains unknown. Today Xiaobian came to introduce some basic knowledge of PVC drainpipe for your reference.

PVC管特征

Characteristics of PVC tube

pvc管材质很轻，搬运、装卸、施工便利，节省人工。pvc管的壁面光滑，流体阻力小，其粗糙系数仅0.009，较其他管材低，在相同的流量下，管径可缩小。pvc管的耐水压强度、耐外压强度、耐冲击强度等都非常高，适用于各种条件下的配管工程。具有优异的电气绝缘性能，适用于电线、电缆的保护套管。pvc管及管件经溶解实验证实不影响水质，为目前自来水配管的最佳管材。

The PVC tube is light in weight, convenient for handling, loading and unloading, and convenient in construction. The wall of PVC tube is smooth, and its fluid resistance is small. Its roughness coefficient is only 0.009, lower than that of other pipes, and the diameter can be reduced under the same flow rate. The PVC pipe has high water pressure resistance, external pressure resistance and impact strength. It is suitable for piping engineering under various conditions. It has excellent electrical insulation performance and is suitable for protecting bushing of wires and cables. PVC pipes and fittings are proved to have no influence on water quality by dissolution experiments, and are the best pipes for piping.

PVC排水管的规格型号有很多，常用的主要有：50、75、110、160、200（外径,单位：mm），按照厚度一般还可分为国标管和I型、II型、III型管，这些都是为了满足工程和预算的需要设计出来的。实际使用中应用较多的还是110规格的排水管。

PVC drainage pipe specifications and models have a lot of commonly used mainly: 50, 75, 110, 160, 200 (outer diameter, unit: mm), in accordance with the thickness of the general can be divided into the national standard tube and I, II, III tube, these are to meet the needs of the project and budget design. In practice, more than 110 standard drains are used.
