![]() Relative expansion: every clamp must be adequately secured and act as a fixture to the bridge. – supporting saddles (α = 120° is a good precaution), Pipelines fixed solidly to the structure Supports The initial concern is to ensure that the structure can support the weight of the main and that provision of anchorages is possible. Systems shown below correspond with the usual types of bridge crossings they are merely given as examples and do not represent the variety of situations that may be encountered.Įvery bridge is a special case and must be specifically studied. There are two principal installation systems, the choice depending on the type of structure: – the protection against freezing, if necessary. – the anchoring of components subjected to hydraulic thrust, – the accommodation of both bridge and main thermal expansions, Comprehensive and Sustainable Solutionsīridge crossing with a push-in joint main involves determining:.Ductile Iron Pipe Expertise by Saint-Gobain PAM.Pre-insulated pipes for frost and temperature protection.Solutions for hydroelectric power stations.Square Gratings for Kerbsides and Car Parks.Gratings - Multi-directional collection.Other channel gratings & Odor-tight inlets P.A.G.Grating AT - Flat grating with frame C250.Class E600 & F900 - Manhole covers for all traffic types in all areas.Class D400 – Manhole covers for traffic lanes, at risk areas and frequent opening.Class C250 – Manhole covers for car parks, gullies, roadsides, walkways and pavements.Class B125 - Manhole covers for pavements.Operating Accessories for Fire Protection.Couplings, Flange Adaptors, Repair Collars and Dismantling Joints.Operating Accessories for Ductile Iron Gate Valves. ![]() Valves and Fittings (Hydrants, Couplings and Flange Adaptors).Process networks: water supply, sewerage, and reuse.Cathaphoresis epoxy (coating for fittings).Anchored solutions for the CLASSIC range - DN 700 to 1800.Anchored solutions for the NATURAL range - DN 60 to 600.Pressure and angular deviation at the joint.Product search, ecommerce, technical specs.
