3D Double Back Fittings

RBV Energy carry the largest range of 3D Double Back reinforced manifold fittings in various worldwide stock locations. Our 3D Double Back manifold fittings are forged from European fine grain AISI 4130 material.

RBV Energy forged 3D Double Back fittings are designed with a 3D bend radius. They are suitable for full-flow applications such as cement and mud systems, where a minimum pressure drop is required.

3D Double Back elbows are availalbe with independent design review, and are fully in compliance with ABS/CDS rules and DNVGL OS-E101 rules.

Our 3D Double Back manifold fittings come in a range of sizes and are available from stock for immediate delivery from our worldwide locations. Download our technical brochure or send us an enquiry for further information.
