Precautions for installation and connection of cement pipe 1. The newly welded joint can be corrected within the specified cooling time, and a small amount of rotation is allowed. However, after the cooling time, forced correction is strictly prohibited. Note: The connected pipes and pipe fittings shall not be inclined. They shall be basically horizontal and vertical to avoid incorrect angle when installing the faucet. 2. It is forbidden to let the newly processed joint bear external force within the specified cooling time. 3. When PP-R pipe fittings with metal threads are used, the white raw material tape must be firmly sealed to avoid water leakage from the threads. 4. When overtightening PP-R pipe fittings with metal threads, the pipe fittings may be cracked, resulting in water leakage. Pay attention to the appropriate force.

With the improvement of people's requirements for living environment, various construction measures have also raised the requirements accordingly. In the construction of drainage and sewage pipelines for urban construction, the requirements for the installation of cement pipelines have also been raised accordingly. This not only makes strict requirements on the quality and material of cement pipes, but also regulates the construction. Corresponding construction management specifications have also been formulated for the installation of cement pipelines. First of all, during installation, it is necessary to measure and set out first, and then dig trenches and earth according to the specifications of cement pipes. When laying the pipeline, the pipeline foundation construction shall be carried out first, and then the cement pipeline shall be cleaned inside the pipe, and then the concrete pouring inspection well and the anchor pouring shall be carried out. After these works are completed, the trench shall be backfilled as required.

7) The grout is repeatedly stirred and lifted. After sinking to the design depth, the grout is repeatedly stirred and lifted until it reaches the ground. 8) The pile driver is moved. After the construction of one pile, move the pile driver to the next pile position, and repeat the above steps for the construction of the next pile. Jiaxing cement pipeline, also known as cement pressure pipe and reinforced concrete pipe, can be used as sewer pipe in urban construction, sewage drainage, flood control and drainage, as well as water supply pipes and farm motor wells used in some special factories and mines. Generally, it is divided into: plain end reinforced concrete cement pipe, flexible rebated reinforced concrete cement pipe, socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, plain end ring joint cement pipe, rebated cement pipe, etc.

Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.

3. For the connection, as long as the flexible rubber ring is used, the street seal can work well. Long term operation. High quality, no leakage 4. The inner wall of the pipeline is flat and yellow, and the fluid friction is relatively small. If used on the ground, the service life will exceed 20 years. Cement pipes have been widely used in industrial production and urban planning and construction, and have played a key role, such as coating pipes used for drinking water, electric power engineering communication equipment, natural gas camp, etc., which must be laid underground. The quality assurance of infrastructure is the foundation of engineering construction in all big cities, so more stringent regulations must be made on the construction materials.
