Mining pipelines Principles pipelines in mines are technical systems which are constantly used mainly for dewatering mines or slurry transport.

Furthermore an outstanding difference to other typical pipelines applications (f.e. drinking water pipelines, turbine penstocks) is the needed flexibility to make changes in the pipenetwork once the pipeline is in operation.

2 Mining pipelines Principles pipelines in mines are technical systems which are constantly used mainly for dewatering mines or slurry transport. Pipes used in mines must usually handle high pressures, daily changes of PH-values or chemical composition of the water. Furthermore an outstanding difference to other typical pipelines applications (f.e. drinking water pipelines, turbine penstocks) is the needed flexibility to make changes in the pipenetwork once the pipeline is in operation. Beside this focus on easy maintenance there is also a high contribution to safety at work. The pipes must be able to function reliably in every situation that can occur f.e. massive soil settlements, earthquakes. Ductile iron pipe systems from TRM with their large safety margins and VRS -T-connection offer this 100% solution through: 1. Operational reliability: Massive. Safe. Compared to other materials, cast iron pipes from TRM offer unique mechanical capabilities and reserves. Therefore our products withstand pressure surges and possible unforeseen influences over a long lifetime. A worldwide unique synthetic modified cement mortar lining offers extraordinary higher adhesive strenght, more elasticity and higher machanical restistance than any other cement lining. 2. VRS -T connection: Simple. Fast. A robust pipe system is created by the most simple locking mechanism which allows a very short installation time. In addition, TRM offers a unique, flexible range of fittings and solutions. 2 Mining pipelines TRM Tiroler Rohre GmbH

Mining pipelines from TRM critical systems require integrated solutions A pipe system is much more than just pipes and fittings.

TRM staff work directly with engineers, construction companies and customers on site to solve problems even before they occur.

This creates the real economic value that goes beyond euros per meter. TRM integrates pipes and other equipment or components in mines.

3 Mining pipelines from TRM critical systems require integrated solutions A pipe system is much more than just pipes and fittings. In a comparison between different pipe materials, developers assess the possibility for adaptation to local conditions and requirements. TRM staff work directly with engineers, construction companies and customers on site to solve problems even before they occur. They rely on many years of experience in this industry and assistance of technical experts at our site in Hall in Tirol, to support during all phases of the project, from planning to commissioning. This creates the real economic value that goes beyond euros per meter. TRM integrates pipes and other equipment or components in mines. If necessary, TRM will clarify the boundary conditions, co-ordinate work with other contractors. This service is becoming increasingly important for customers, especially where liability issues are concerned. After all, who can guarantee the reliability of the overall pipe system if many single components are bought from various traders instead of from one OEM? Who is reliable if intermediate traders were chosen when the pipeline was contracted? If additional goods are found to be necessary during construction, will they actually be able to be supplied on time? Developers and firms installing mining pipelines are already considering this today and are opting for real solutions made by TRM, made in Austria. TRM Tiroler Rohre GmbH Mining pipelines 3

4 Mining pipelines Adapter and expansion piece Used to compensate for building tolerances when ductile cast iron pipes are fitted and to enable easier dismantling of pipe parts in case of maintenauce. MMB branch piece with socket creates a simple, highly durable branch and saves on fittings. Easy connection for air- or drain valves. Expansion joint to absorb slope movements. The insert length of the lower socket is longer than usual. The spigot inserted can move in the fitting and hence absorb slope movements. Inlet cone Inflow opening into the ductile cast iron pipe. MK fitting Bend with socket and spigot. Different angles are available. 4 Mining pipelines TRM Tiroler Rohre GmbH

In order to ensure that the safety reserves of the ductile iron pipe are met by the entire pipe system, operators rely on the positive locked VRS -T-connection.

6 Full speed! VRS -T-connection and the mechanical properties of the material are the top choice for mining pipelines. Ductile means deformable. The endurance test shows the mechanical capabilities and reserves that are unique for ductile iron the top choice for mining pipelines with stringent safety requirements. In order to ensure that the safety reserves of the ductile iron pipe are met by the entire pipe system, operators rely on the positive locked VRS -T-connection. In this way, individual pipes are connected to form one system without the need for time-consuming welding, screwing, testing, later surface treatment or problems during loosening and adaptation of connections. tolerances to be compensated for. Detailed information for planning can be found in our ductile iron pipe systems manual that can be downloaded at VRS -T at a glance The simple installation process doesn't just save time; in most cases it can be carried out by the construction firms themselves. VRS -T flange connection (16 screws PN16) The pipes can be deflected up to 5 per joint. This means that, with a resulting curve radius of 57 m, the ductile iron pipe can be adapted to follow the direction of the road, bridge or tunnel, and savings can be made on fittings. Furthermore, the system allows building welding Assembly time [min] Up to 3x faster installation than flange connections. Up to 6x faster than welding steel pipelines Retaining chamber Weld bead VRS -T / TYTON gasket Socket Lock Spigot 6 Mining pipelines TRM Tiroler Rohre GmbH
