Ductile pipe for its excellent mechanical properties and external quality, is the carrier of pipe water supply enterprise, its strong bearing capacity, reliable sealing performance, incomparable anticorrosive processing and quality assurance system, makes the pipe water supply nearly perfect, even in the complex terrain of saline-alkali land, wetland, high pitched and desert balanced soil, also can complete the task of water supply excellent new ductile pipe
, has certain frost resistance, as long as no special circumstances, the basic won't appear frost crack and detonation tube.
But, like all building products, ductile iron pipe fittings has its own life cycle, after a certain time of operation, the life of the ductile iron pipes will disappear as network traffic.
So, in the use of maintenance and maintenance is a very important link, it can help us more effective to maintain normal use of the product.
Ductile iron pipes as most used nowadays pipeline system of pipes, its daily maintenance and maintenance is also very important, ductile iron pipe use of preventive maintenance and should be paid attention to the following: 1, ductile pipe maintenance can always start from its selection, before the project starts we should to the necessary components required, such as pipe pieces, aprons, bend line a the appearance of the visual inspection to the naked eye, avoid of diseased parts.
2, the second maintenance work focuses on the acceptance of the time we should focus on attention to affect long-term stable operation of pipe under the socket, aprons,
And so on, to strive for in the aspects of socket without sundry.
Is north of synthetic rubber hammer hit real don't become warped twisting, evenly card in the slot.
3, in the process of ductile iron pipe maintenance, because of the moving tube axis is deeply buried in the ground, so it comes to the tilt Angle, be careful, if the resistance is too large, do not forcibly excavation, in case of twisted rubber ring.
Ductile pipe in winter maintenance also need to pay attention to preheat with hot water, to reduce hardness, rapid installation.
4, if the project is adopted by the ductile iron pipes in terms of quality absolutely conforms to the national standard, so we should pay attention to ac/dc aprons, welding, etc.
Ductile iron pipes as a to improve the construction environment of new type pipe, only used properly, the product quality, to reduce unnecessary trouble in the installation project and maintenance in the future work is also relatively easy.
