RBV Energy forged 3D double-back elbows are designed with a 3D bend radius and additional reinforcement on the outside of the bend to protect against erosion. They are suitable for full-flow applications such as cement and mud systems, where a minimum pressure drop is required.
3D double-back elbows come with ABS independent design review, and are fully in compliance with ABS/CDS rules.
