What is the pressure of a concrete pump line?

Overview of Pressure in Concrete Pump Pipes
As a key component in the concrete conveying system, the pressure borne by the concrete pump pipe directly affects the safety and work efficiency of the entire pumping system. Generally speaking, the working pressure range of concrete pump pipes is usually between 5-20MPa, and the specific value depends on various factors such as the model of pumping equipment, the mix proportion of concrete, and the delivery distance.
The main factors affecting the pressure of concrete pump pipes
Performance of pumping equipment: The maximum output pressure of different types of concrete pumps varies greatly. Small pumps may reach around 10MPa, while large high-pressure pumps can reach 20MPa or even higher.
Conveying distance: For every 100 meters increase in horizontal conveying distance, the pressure loss is about 0.1-0.15 MPa; For every 10 meters increase in vertical height, the pressure increases by approximately 0.25 MPa.
Concrete characteristics: Concrete with low slump and high viscosity requires higher pumping pressure, usually 15% -30% higher than ordinary concrete.
Pipeline layout: The more bends and angles there are, the greater the system pressure loss. Each 90 ° bend is equivalent to an additional 8-12 meters of horizontal pipe pressure loss.

Pressure rating of concrete pump pipes
The common concrete pump pipes in the market can be divided into:
Low pressure pipe: working pressure ≤ 10MPa
Medium pressure pipe: working pressure 10-16MPa
High pressure pipe: working pressure 16-22MPa
Ultra high pressure pipe: working pressure>22MPa

Pressure safety considerations for concrete pump pipes
To ensure construction safety, the actual working pressure of the pump pipe should not exceed 80% of its rated pressure. At the same time, the system should be equipped with a pressure relief device that can automatically release pressure when the pressure exceeds the set value. Regular pressure testing is also an important measure to ensure the safe use of pump tubes. It is recommended to conduct a comprehensive inspection every 6 months or every 5000 working hours.

Choosing the appropriate pressure rating for concrete pump pipes requires comprehensive consideration of factors such as pumping equipment parameters, engineering requirements, and construction conditions. As a professional supplier of concrete pump pipes, we recommend that customers choose fittings with appropriate pressure levels based on specific working conditions and regularly maintain and inspect them to ensure construction safety and extend the service life of pipelines.
