Seal ring is the most commonly used Concrete Pump Pipe fitting. It is made of rubber. It is used in the Concrete Pump Pipe to seal. In the winter, the temperature drops sharply. How should the Concrete Pump Pipe in the construction be insulated? Let us introduce the insulation method of the Concrete Pump Pipe.
The concrete pump pipe rubber ring is the sealing ring used to connect the pump pipe.
From the model, the concrete pump pipe has DN125,DN80,DN150,DN180, DN100, and its named method is based on the inner diameter of the pipe.For example, the pump pipe with internal diameter 125, the sealing ring is called DN125 sealing ring
The normal operating temperature of the Seal ring is usually between -40 and 120 °C. If the temperature exceeds 120 °C, you should consider the use of FKM material or PTFE material Seal ring. For the low temperature condition is relatively rare, usually under the conditions of -20–40 ° C, the need to consider the use of cold-resistant NBR material, NBR material under low temperature conditions, the material will become hard, leakage phenomenon.
Concrete Pump Pipe is coated with flame-retardant straw curtain and wrapped, and the long-side winding pump tube with straw curtain is wrapped and the loud straw curtains should be overlapped with each other. After pouring the concrete every day, see the concrete. If the concrete inside the pump tube is cleaned, there is no water in the pump tube to prevent the water from freezing.
Concrete structure engineering construction adopts integrated heat storage method. When the temperature is low, in order to ensure the quality of the project, according to the construction area. The furnace is uniformly erected with six furnaces for heating. The lower part of the furnace is 60cm above the ground. The upper part of the furnace is placed with steel plates to distribute the heat evenly. The upper part of the steel plate is placed in a bucket to maintain the air humidity to avoid concentrated heat above and below the furnace, resulting in premature water loss of the concrete. Cracks and other phenomena.

The choice of pressure is important. This also affects the way the rubber seal ring is used in the rubber fittings to be used. In general, there is little doubt about the choice of rubber or PU seals in low and medium pressure conditions. However, it is necessary to think about a problem of impact pressure. For example, in engineering machinery, when the engine is closed, its impact pressure is far greater than the normal working pressure. Therefore, it is usually used to withstand the impact resistance of 70MPA.
