2.5 Spools, Spacer (Riser Spools)

WOODCO USA manufactures Spacer Spools in all sizes and pressure ratings suitable for Well Head extension, B.O.P. spacing, and Choke, Kill, and Production Manifold applications. Spacer Spools usually have the same nominal end connections. Spacer Spool identification consists of naming each end connection and the overall length (outside of end connection face to outside of end connection face), e.g. 20-3/4" 3000 X 20-3/4" 3000 X 10' O.A.L. Should a requirement for differing end connections occur, their identification consists of describing them in the same manner, e.g. 20-3/4" 3000  X 21-1/4" 2000 X 10' O.A.L.

WOODCO USA Spacer Spools usually do not have outlets, but customers may specify outlets and/or lifting pad eyes.
