Permanent ways

In the case of a railway track, the track bed with the assembled tracks,is called permanent way. The foundation, a solid base for the track structure, is located underneath it. The permanent way normally consists of the ballast track bed on which sleepers are placed and the rails which are fixed on the sleepers with fastenings. The ballast track bed is very good at absorbing the forces introduced by the vehicles and can distribute them on to the foundation

Underwater Welding

Ever more significance is being attached to underwater welding due to the increasing utilisation of offshore wind farms. Underwater welding is used for the construction and maintenance of docks, waterways, underwater pipelines, lock installations, dams, hydroelectric power stations and offshore platforms, for shipbuilding as well as for salvaging measures. At present, the public is following the complicated salvaging of the Costa Concordia cruise ship off the Italian island of Giglio. This is only possible due to one of the largest deployments of welding divers in history.

Pipeline construction

Pipeline construction encompasses all types of pipelines which are utilised for transporting all kinds of things, e.g. liquids, gases and district heating. All over the world, approx. 155 million tons of steel pipes made of various materials are produced per year. In this respect, German steel construction producers account for approx. 2.7 million tons.


Pressure devices

Pressure devices are defined by the European "Pressure Device Directive" (PDD) 97/23/EC. The directive stipulates the requirements on the pressure devices for the introduction of pressure devices on to the market within the European Economic Area. Since the 29th of May 2002, the PDD is binding throughout the European Union.
