The cement pipes produced by large-caliber cement pipe manufacturers are used as pipes for drainage and gas transmission in urban construction. Therefore, the quality of cement pipes is appropriately important. The quality of cement pipes produced by large-caliber cement pipe manufacturers ensures quality and affordable prices. Next, I will analyze how to distinguish the quality of cement pipes for us!
First of all, in the production of cement pipes , the fineness, initial setting time, insoluble matter, and loss on ignition must conform to the specifications. If it does not match or the mixture is doped with impurities that exceed the specified target, it can be regarded as not. qualified. Qualified cement pipes are usually marked with the manufacturer's title and product number.
Secondly, in addition to paying attention to the production process, it is also necessary to pay equal attention to the storage and storage of cement pipes . For example, during transportation and storage, do not mix in debris and ensure that it has a certain humidity to ensure that the initial setting time is satisfied. Cement pipes of different types and strength grades should be stored separately. When using cement pipes, the first-to-be-first-used rule should be used. In addition, when the cement pipes are transported to the construction site, they should be inspected immediately. No fouling or missing corners shall be present to ensure the quality of the construction work.
The production, sales, and service life of cement pipelines are also affected by the season, and especially in winter, they should pay more attention to their maintenance methods. Today, large-caliber cement pipe manufacturers teach us some of the most useful cement pipe maintenance methods to extend the service life of cement pipes .
1. The most suitable maintenance method for cement pipelines in winter is steam curing.
The first requirement is to build a steam curing pond. The steam curing pond can be determined according to its own needs. It also requires the boiler to transport steam to the steam curing pond. The degree of sealing of the steam curing pond is better. After the cement pipe is formed, it can be hoisted into the steaming pond for steaming. Generally, steaming is required for 2.5--3.5 hours. Generally, the higher the temperature, the shorter the time of steaming. The time of steaming is inversely proportional to the temperature of steam. The higher the temperature, the better. The steam curing method has fast maintenance and good effect.
2. Another maintenance method for cement pipelines is natural maintenance.
After the cement pipeline is finished, the cement pipeline and mold are placed in the open air for natural maintenance. Generally, it is required to perform open-air maintenance at the time of the day, and then the mold is opened the next day. After the mold is opened, natural maintenance is required for 4--6 days. A special person sprays water on the cement pipe three times a day, usually once in the morning, once at noon and once in the afternoon. The purpose of water spray is to adhere to the humidity of the cement pipe so that the concrete can gradually set itself, and the number of water sprays can be added and reduced according to the weather conditions and the humidity of the air.
In the end, the large-diameter cement pipe manufacturers notified us that new cement pipes also require maintenance, but in the process of use, we must strictly abide by the provisions in the main parameters, keep in mind the overload, choose a moderate weight center of gravity, and just select the power of the electric jack. Point, the bottom surface should be flat, and at the same time, the soft and hard conditions on the ground should be considered, whether the tough wood should be lined, and whether the placement is stable. Only by adopting the most correct method of use, can the useful life of the cement pipeline be extended.
