Concrete Pump Pipes Buying Guide
Concrete pump parts are a relatively demanding accessory, and their quality is related to the service life of the pump truck, which also makes a strong concern in the machinery manufacturing industry.
The processing technology of the pump pipe is relatively high, requiring it to be not only lightweight but also wear resistant. Light weight means that the pump boom can be made longer. Wear resistance means a longer service life, which can bring direct economic benefits to the user. Therefore, the selection of concrete pump pipe is especially important.
Concrete pump pipes
are generally divided into straight pipes, elbows and cone pipes. The size can be divided into 125A and 150A, 175A, which are divided into high pressure and low pressure. Generally, the pump pipes used on the concrete pump boom are 125A low pressure pump pipes. Only 150A elbows are used for discharging, and elbows pipes are used for docking 150A and 125A cone pipes.
Pump pipes are generally fabricated using seamless steel tube monolithic forming techniques and then subjected to various heat treatments. The pipe head of the pump pipe is connected to the pipe body by welding through a specially processed pipe joint, and the connection of each pipe is connected by a pipe card processed by a precision casting process.
The operating temperature range of the pump pipe is another important factor to consider. Some pipes, such as silicone rubber, have a wide temperature range and are suitable for high temperature and low temperature processes. Some pipes such as Tygon and C-Flex are suitable for a small temperature range. In applications where temperature is to be gradually increased, the end user should consider the effect of temperature on the chemical resistance and pressure capacity of the pump tube. When the temperature is increased, the pressure capacity of the pump tube is reduced.
Before selecting the pump pipe, all the pressure sources in the system should be clarified and the measured values of the total system pressure should be obtained. If the pressure is too high, the pump pipe will swell and will not work well with the pump head, resulting in excessive wear and failure of the runt. When the system pressure greatly exceeds the bearing capacity of the pump pipe, the pump pipe may even burst and spray fluid, which may endanger safety. If the system exceeds the maximum working pressure, a simple pressure relief valve or pressure switch can be installed to prevent accumulation of excess pressure.
