1. Good seismic performance
The clamp-type cast iron drainage pipe has a flexible joint, and the axial eccentric angle between the two pipes can reach 5°, which can fully meet the requirements of earthquake resistance.
2. Easy to install and replace pipes
Due to the lighter weight of the clamp-type cast iron drainage pipe, and the use of clamp joints as “live joints”, there is no nesting between pipes and pipes and fittings. No matter installation, disassembly, and replacement of pipes, it is better than traditional sockets. Convenient cast iron drainage pipes. The labor cost is naturally low.
3. Low noise
Because of the flexible rubber connection, it can effectively prevent the noise generated by sanitary appliances from being transmitted through the pipeline.
From the above comparison, it can be seen that the clamp-type cast iron drainage pipe is a replacement product of the traditional cast iron drainage pipe. Its performance in all aspects is better than that of the traditional socket cast iron drainage pipe and should be promoted. The only disadvantage is that the material price of this kind of pipe is relatively high. At this stage, it is only suitable for promotion and use in super high-rise buildings, more important public buildings, and buildings with higher seismic requirements.
5. Compared with UPVC drainage pipe:
(2)Good fire resistance.
(4)The expansion and contraction coefficient is small.
(5)Good wear resistance and high temperature resistance.
Comparison with other cast iron drainage pipes with sockets and flexible joints. Flexible joint cast iron drainage pipes with sockets have more than ten joint forms, the more representative ones are socket type and flange type. Compared with this type of pipe, the clamp-type cast iron drainage pipe has the following advantages:
1. Light weight
Although some cast iron drainage pipes with flexible sockets are manufactured by centrifugal casting process, the pipe wall thickness is uniform, but in order to ensure the strength of the socket, the thickness of the pipe has to be thicker. Due to the heavier weight per unit length, the cost of the flexible joint drainage cast iron pipe with socket is higher.
2. Small installation size, easy to replace
The joint size of the cast iron drainage pipe with socket flexible joint is large, especially the flange gland type. It is inconvenient whether it is installed in the pipe well or against the wall. When there are more sanitary appliances, more short pipes are used, and the pipe material is wasted. Larger. In addition, when repairing and replacing the pipe, the pipe must be sawn off before being able to exit the pipe. The installation size of the clamp-type cast iron drain pipe is much smaller. In addition, this kind of pipeline adopts flat connection, which is very convenient for installation and replacement.
