CONCRETE CURING APPARATUS

摘要

Pipes of the type used in subterranean or submerged pipelines for the recovery of oil, gas, slurries or the like pipeable materials from a subterranean well are coated with concrete using apparatus comprising a plurality of mobile pipe carriers (15), an insulated enclosure (20) in which there is provided a controlled wet atmosphere maintained at an elevated temperature, said enclosure being sized to accommodate a multiplicity of pipes together with pipe carriers, and means (30, 30') for sequentially advancing said pipe carriers in continual succession through said insulated enclosure.
