W型铸铁管与A型、B型铸铁管的比较

作者: -1    发布时间: 2018-07-26    次浏览
W型铸铁管与A型、B型铸铁管的比较之A型管材:A型管材具有接口强度高、密封性好、抗振性能强的优点。但由于为了保证承口处的强度,就需要管道壁厚较大,相应造价就比较高。另外,根据设计要求和现场实际,需要对直管长度进行裁取,切割下来的直管段不能再次利用,材料浪费相当大。所以,近些年A型柔性铸铁排水管在市场上的占有率大幅的下降。
The comparison between w-type cast iron pipe and a-type and b-type cast iron pipe shows that a-type pipe has the advantages of high joint strength, good sealing and strong vibration resistance. However, in order to ensure the strength of the socket, the pipe wall thickness is required to be large, and the corresponding cost is relatively high. In addition, according to the design requirements and the actual situation of the site, the length of the straight pipe should be cut off. The cut straight pipe segment cannot be reused, and the material waste is quite large. Therefore, in recent years, the market share of type A flexible cast iron drain pipe has dropped significantly.

W型铸铁管与A型、B型铸铁管的比较之B型管材:B型管材结合了W型直管长度可以按需套裁、A型接口强度高的优点,逐渐被市场所接受和选用。
W type cast iron pipe and the comparison of type A, type B cast iron pipe of B type pipe: B type pipe combines W straight pipe length can be on-demand suit cut, the advantages of high strength type A interface, is gradually accepted by the market and use.

W型铸铁管与A型、B型铸铁管的比较之下,W型管材具有以下优点:
Compared with type A and type B cast iron pipes, type W pipe has the following advantages:

(1)重量轻
 (1) light weight

B型铸铁管虽采用了W型的直管,但管件仍然带承口,管件壁较厚,连接方式为承插式法兰连接。论文参考网。因此,W型铸铁管总体上较A型、B型管材重量轻,造价低。
Type B cast iron pipe adopts w-type straight pipe, but the pipe fittings still have socket, the pipe fittings have thick wall, the connection mode is socket flange connection. Paper reference network. Therefore, W cast iron pipe is generally lighter in weight and lower in cost than A and B cast iron pipe.

(2)径向尺寸小(无法兰盘)、便于布置、节省空间
 (2) small radial dimension (no flange), easy to arrange and save space

(3)拆装方便
 (3) convenient disassembly and installation

 The w-type cast iron pipe adopts the method of connecting with a hoop. The hoop bolt is tightened outside the interface, which is easy to operate. For maintenance without as type A and type B cast iron pipe to sawing to exit the pipe or pipe fitting, but need to loosen the clamp can be on both ends of the pipe or pipe fitting, very easy to construction or use of the pipeline replacement and maintenance.
