Nitrogen systems Overview Nitrogen systems are heavy-duty and flexible alternatives to mechanical spring elements. They provide optimal solutions for complex projects with various compressive forces and the same spring force. They are compact and require less installation space than mechanical spring elements. With nitrogen systems, the installation height of the tools can be reduced and the force progressions optimised. Whether it concerns the selection and design of the nitrogen cylinders, combined solutions or individual manifold plates – with STEINEL nitrogen systems, you will always have...

Nitrogen cylinders can be easily integrated into the tool and increase availability with regard to mechanical spring elements. Preloading is not needed, which facilitates improved handling. Advantages ■ outstanding lifetimes due to innovative sealing materials, lifetime lubrication and two-point piston support ■ large product range for each installation situation and application ■ rapid availability of all products thanks to extensive warehousing Safety features ■ maximum security thanks to FEM-calculated components ■ application of PED directives (Pressure Equipment Directive DGRL) ■ constant...

Nitrogen systems Burst protection burst disc burst screw All STEINEL nitrogen cylinders with outer diameters from 32 mm are available with burst protection, in the form of a burst screw with integrated burst disc, upon request. All STEINEL control panels are equipped with burst protection as standard. The burst disc cracks when a specified pressure level has been exceeded, and the nitrogen can then immediately leak out. By using burst protection, the nitrogen cylinder is protected from overpressure damage. Advantages prevents consequential damage to nitrogen systems and tool nitrogen systems are...

In composite tube systems, multiple nitrogen cylinders and a control panel are connected using tube lines in order to standardise system pressure. Compared to nitrogen cylinders, the total volume of nitrogen in the system is easily increased through the tube lines, which leads to a flattening of both the pressure increase and the force curve. All of the nitrogen cylinders within a pressure cycle have a standardised pressure level, which means that the force ratio between them is constant. This lowers the risk of tilting, reduces the lateral forces in the guide units and thus guarantees effective...

Composite plate systems consist of several nitrogen cylinders, a control panels and the composite plate. All components are connected to one another via boreholes in the composite plate. As with composite tube systems, this ensures standardised system pressure and a larger nitrogen volume, resulting in a flatter force curve. The standardised pressure and therefore the uniform force ratio lowers the risk of tilting, reduces the lateral forces in the guide units and thus guarantees effective tool protection. The direct nitrogen supply via the lower plate reduces the sealing points in comparison...

Nitrogen systems Installation instructions Nitrogen cylinders must be screwed via the mounting threads on the housing base, and never on the piston. The thread in the piston surface is only meant for nitrogen cylinder assembly and no other parts may be screwed on to it. The nitrogen cylinders must be installed coaxial to the acting force. The piston rod surface must be completely impinged. The contact surface should be suitably hardened. The screw-on surface must be flat and parallel to the pressure surface. The nitrogen cylinders must not be preloaded in the tool. If preloaded nitrogen cylinders...

Manifold plates are constructed and manufactured according to customer specifications. They consist of a metal plate with volume boreholes as an integrated nitrogen buffer, space-saving manifold cylinders and control panels. The nitrogen buffer's large volume allows for a very low force increase. Drawing cushion STEINEL also provides machine-bound drawing cushions as a special form of manifold plate. The spring forces are transmitted through guide pins to the correct location in the tool. With phenomenal lifetimes, a high number of cycles and a very low mass to be moved, nitrogen drawing cushions...
