Perfect Pipe: Future-proof concrete pipes

Perfect Pipe+: the pipe base geometry not only facilitates pipe handling on the job site and the positional stability of the pipeline. The level supports also provide benefits during transport and storage

The automatic welding of the inner liner ensures that inner liners are always impermeable for further treatment in the subsequent Perfect Pipe production steps

The liner ends are shaped to fit the contours of the pipe socket in a thermoplastic molding process

The molds designed for horizontal production are provided either with or without liner for the casting process, which is also automated

SCC is continuously conveyed from the mixer to the casting unit via a feed hopper

A robot grabs the filled mold and places it in its defined curing position. The robot then takes a mold with the hardened product and releases it for automatic demolding in the production line

Another robot takes the product out of the mold after its automatic opening

In the next step, the inner steel core (which is fitted with a newly developed spreading mechanism) still located in the pipe is ejected automatically

Following an in-line vacuum test, the demolded products are grouped in packages according to their nominal diameters, placed on the exit conveyor and moved out of the factory building for transport purposes

First drainage pipelines were installed to verify the claimed product benefits, which were fully confirmed

A new era of precast pipe production begins at Betonwerk Müller in the German state of Baden-Württemberg. The Perfect Pipe system developed by Schlüsselbauer ensures durable sewage pipe systems whilst adding value at the precast plant.

The production of pipes for wastewater treatment and sewage is subject to continuous change. Specific materials are literally booming as a result of advancements in construction practice, changes to applicable standards and legislation, and – last but not least – the availability of new technologies. During the past few decades, the concrete pipe industry has mostly played a passive role in this regard. Product innovations using various materials other than concrete have repeatedly gained market share over concrete pipes. This trend contributed the reducing number of precast pipe suppliers....
