Maintenance and maintenance of ductile pipe in Guiyang foundry
Guiyang foundry introduces the maintenance of spheroidal graphite tubes, so we should always start with its selection。 Before the project starts, we should do a naked eye visual inspection for the components that need to be used, such as pipes, aprons and elbow, so as to avoid using sick parts。
The second point of maintenance is the acceptance time. We should pay attention to the influence on the long and stable operation of the socket, the rubber ring and the lower pipe (drain pipe). We must try to make sure that there is no debris in these respects. The rubber ring has been hammered and not twisted by the North rubber hammer, and it is stuck evenly in the slot.
During the maintenance process of the Guiyang foundry, it is necessary to be careful when the inclination angle is encountered when the axis of the moving tube is buried deep underground。 If the resistance is too large, we must not force the excavation to prevent the rubber ring from twisting。
The maintenance of Guiyang cast iron pipes in winter needs to be preheated with hot water in order to reduce the hardness and install quickly.
In addition, if the quality of the Guiyang cast iron pipe used in the project is absolutely in conformity with the national standard, we should pay attention to the AC and DC dual use of the rubber ring and welding.
Guiyang cast iron pipe as a new material to improve the construction environment, only properly applied, excellent product quality, in order to reduce unnecessary trouble in the installation project, maintenance work, after also relatively easy。
