ABSTRACT:
There is provided an improved guide arch for guiding the movement of continuous production tubing through a predetermined curvature, the guide arch comprising a housing and an endless curved conveyor mounted within the housing to support the tubing through its curvature, wherein the conveyor continuously supports the tubing along the majority of its length passing through the arch to thereby reduce contact stress between the tubing and the conveyor.
