Abstract
A fluid flow control assembly includes a first pipe-in-pipe assembly comprising an inner tubular member disposed in an outer tubular member, wherein the inner tubular member comprises an inner bore and an annulus is formed between the inner tubular member and the outer tubular member, a terminating bulkhead assembly coupled to the first pipe-in-pipe assembly, wherein fluid communication is provided between a bore of the bulkhead assembly and the inner bore of the inner tubular member while fluid communication is restricted between the bore of the bulkhead assembly and the annulus of the first pipe-in-pipe assembly, and an annulus conduit coupled to a radial port of the first pipe-in-pipe assembly, wherein fluid communication is provided between the annulus conduit and the annulus of the first pipe-in-pipe assembly while fluid communication is restricted between the annulus conduit and the inner bore of the inner tubular member.
