Los acoplamientos mecánicos y los adaptadores de brida son componentes fundamentales que garantizan que las redes de tuberías no presenten fugas y sean flexibles y resistentes.
Los productos para la reparación de tuberías ofrecen una forma rápida y segura de sellar grietas, agujeros y secciones corroídas al instante —a menudo bajo la presión total del sistema—, evitando así la necesidad de costosas y largas interrupciones en la red.
Laing O’Rourke were the main contractors involved in the construction of a new 2.5km replacement clean water pipeline, which is part of the Derwent Valley Aqueduct (DVA) triplication scheme, on behalf of Severn Trent Water.

La solución
The scheme required the laying of a replacement pipeline around the edge of Swithland Wood and the upgrade of Hallgates Water Treatment Works with a new break pressure tank and pumping station. Viking Johnson were pleased to support this project by supplying products made to suit the specific pipe OD of ductile iron pipe. Viking Johnson step couplings were required to downsize to a tee piece which fed to a connecting pipeline.
Ventajas de la solución
Couplings can absorb up to 10mm expansion and contraction, flange adaptors up to 5mm which allows for movement on bridge crossings, in chambers and pump stations. Often eliminates the need for special expansion joints.
Couplings can offer up to 6° of angular deflection, flange adaptors 3° – to allow for the connection of misaligned pipes; take up ground settlement at structures; lay pipes to large radius bends.
The standard finish for all Viking Johnson products is black Rilsan Nylon 11, which is highly resistant to impact, corrosion, abrasion and chemical attack. However, other coatings such as shopcoat, hot dip galvanising, zinc spray and epoxy coating can be supplied as required.
