Concrete pump pipe bends used on ground pumps

Concrete pumping pipe bend is a key connecting part in the concrete conveying system, mainly used to change the direction of the pumping pipe. In concrete pumping construction, due to the complexity of the construction site and space limitations, the pipeline often needs to be turned several times in order to accurately deliver concrete to the pouring location. The existence of bends makes the pipeline system flexible to adapt to various building structures and realize 360-degree all-round concrete delivery. As a professional supplier of concrete pump fittings, we are well aware that the quality of pipe bends is directly related to the efficiency and safety of the entire pumping system.

Classification of concrete pump pipe bends
Concrete pump pipe bends play a role in changing direction in the conveying pipeline, which can be divided into two kinds of floor pump bends and pump truck bends.
Concrete pump elbow is used in the tractor pump, truck mounted pump, specifications R350, R500, R750, R1000 several kinds, the angle of 15 °, 30 °, 45 °, 90 ° several kinds of R500 and R1000 the two most commonly used, R350 is mainly used in the hand-operated material machine. DN125 is divided into two kinds of high-pressure and low-pressure, reminding users to pay attention to the distinction.
Concrete pump truck elbow used in pump trucks, specifications R275, R190.5, R180, R240, R385, R500, R315, R460 and so on. The common pump truck elbow is cast and processed, and there is a double-layer pump truck elbow, which has a longer service life and is more cost-effective.

Notes on the selection and use of concrete pump pipe bends
Choosing the right elbow needs to consider a number of factors: the pressure level of the concrete pump, the maximum particle size of the aggregate, the conveying distance and the construction environment. High-pressure pumping should prioritize the use of thickened bends; for concrete containing large particle size aggregates, bends with larger inner diameters should be selected to reduce the risk of clogging. In actual use, it is recommended to rotate the elbow regularly to even out the wear and prolong the service life. During installation, it should be noted that the bending direction of the elbow should be the same as the concrete flow direction as far as possible to avoid the pressure surge caused by sharp turns. At the same time, should avoid using too many bends in the same conveying line, generally each additional 90-degree bend is equivalent to an increase of 8-12 meters of horizontal conveying distance resistance.

As a key component of the concrete pumping system, high-quality bends can not only improve construction efficiency, but also reduce maintenance costs and downtime risk. Professional pumping pipe suppliers can not only provide standard products, but also provide optimized piping arrangement and technical support according to customer’s specific working conditions.
