Our Long Sweep manifold fittings are forged from the highest quality fine grain AISI 4130 material. The refined fine grain structure manufacturing process enhances toughness at all levels and provides vastly superior thro-thickness mechanical properties and strength both in the longitudinal and transverse directions.
4130 Fittings
Marcore 4130 fittings are fully-forged for high load and cyclic capability. We manufacture to the highest industry standards & tolerances. Our long sweep and 3D double back elbows and bends are dual fully certified in strict accordance with the latest offshore drilling and piping specifications. Marcore long sweep manifold fittings are manufactured in the UK from the highest quality, UK or European sourced materials, and are available with design and type approval. We carry a large stock of 4130 manifold fittings, which are available for immediate delivery.
