Pipes and Pipe Accessories for the Water Sector
We offer a comprehensive range of pipe fittings and steel pipes for drinking water, wastewater, and process water applications. Our product portfolio includes pipes and accessories in various coating combinations and materials. In addition, we provide connection systems tailored to your needs—from weld seam preparation and welding to flanges, couplings, and quick-connect systems.
Fittings
Welded and Seamless Fittings According to Standards
We offer welded and seamless fittings in accordance with DIN EN 10253-2 / -4. Our range includes elbows (BA2, BA3, BA5) in various angles, tees, concentric and eccentric reducers, and dished ends. Standard sizes are available up to DN 2000, with certain shapes and configurations available up to DN 3000.
Custom Parts According to Customer Specifications
We supply segmented bends according to technical standards or customer specifications, as well as gussets/double gussets, also available as pre-fabricated tees. Our range includes welded elbows, siphons, manifolds, flat pipe segments, and Y-pieces with individual weights of up to 5 tons. Standard sizes go up to DN 2000, and specific shapes and configurations are possible up to DN 3000.
