The MSL displacement pipes made of steel strips are very good bearing hollow bodies which can be checked for stability. Not just plate thickness but also form, height and number of beads are the decisive factors for stability. MSL produces 35 different pipe diameters from 0.1 to 2 meters and can thereby supply almost all dimensions required in the construction industry as a folded spiral tube. Since the end of the 1960s, we have been manufacturing displacement pipes at our company for the widest range of applications in Germany, Europe but also for overseas.
Thus, a MSL displacement pipe in the diameter of 1.8 meters was supplied as casing for a ventilation shaft for a tunnel construction site.
A very large area of application is in the area of bridge engineering. Here several thousand meters were produced in different diameters for many bridge projects in Germany, Austria, France and Africa.
By using connector joints, any extruded length can be created on site. To ensure buoyancy, single or dual point anchors can be supplied depending on the need. Distance brackets are offered for leveling and distancing of the displacement pipes according to the pipe diameters and the height dimensions required by the statical engineer. Instead of an end cover, a conical end lock ca be attached to the pipe which guarantees better laying of the prestressing elements at the end of the displacement pipe.
We are happy to provide you with further information on the topic of displacement pipes in bridge construction such as the anchoring system and assembly instructions. MSL displace-ment pipes are generally manufactured from Sendzimier-galvanised plates in individual lengths of 6 to 10 meters.
