When a leading firm in water and oil well drilling approached us to design a revolutionary centraliser we didn’t know what that was. Designed to clamp around pipes and casings, they hold the pipe or casing central in the hole, which is critical for many applications, such as when the casing is to be grouted in to hold it firmly central to the well. Finite Element Analysis (FEA) guided the design to achieve optimal strength without wasting material – which is a high strain thermoplastic suitable for the severe environmental conditions encountered yet meets all regulatory requirements.
