concrete pump twin wall pipe, double layer boom pipe, st52 & alloy steel layer wear resistant

by admin / Sunday, 24 September 2017 / Published in Concrete pump pipe

are more important than ever for the pumping of ready-mixed concrete. Especially for deadline-bound projects, conveying pipes must not fail.

Single-layer ST52 pipes will wear out within very short periods of time. This results in high costs for service providers in the ready-mixed concrete industry because of downtime due to repairs, service / maintenance work or the replacement of components.

CZPPCO have developed and produced conveying pipes, elbows and special delivery line parts for truck-mounted concrete pumps, truck mixers concrete pumps or concrete distributing booms since 1998. The two-layer CZPPCO TWIN PIPES achieve a service life, which is significantly longer than ST52 pipes.

The special hardening process and high-quality welding process ensure that CZPPpipes achieve a service life, which is many times longer than that of commonly available ST52 pipes with the same wall thickness. Boom pipes shall not exceed the specified weight in order to ensure that the stability of the machine is not endangered.

Our pipes are checked for their pressure resistance at regular intervals. The hardness of TWIN PIPE pipes is constant over the entire pipe length so that service intervals can be scheduled more easily. All of our products are manufactured subject to the pump manufacturers’ specifications.

Today, CZPPconveying pipes are used globally.

All CZPPpipes are manufactured in accordance with the weight specifications by concrete pump manufacturers. Conveying pipes for booms are available in two different quality levels. We recommend that you use the CZPP900 XL pipe where you get extreme wear e.g. behind an 10-45° elbow. Those pipes have an extended inlet weld collar to compensate the wear.
