AF Pipe Solutions offers full double piping arrangements with the AF Slim double pipe product line, delivering a full set of double pipe spools from basic line routings, or to exact customer requirements from isometric drawings. The AF Slim double pipe product line is an extremely compact double wall pipe design, where the inner pipe is installed in the outer pipe using propietary expansion tooling and procedures, and full piping arrangements can be delivered with AF Slim bends, and AF Slim couplings. The AF Slim double pipe arrangements are normally custom designed according to process and regulatory requirements, based on some standard pipe dimensions. Typically the outer pipe is produced according to the same design criteria as the inner pipe. The annular space is closed at both ends, so pressure or temperature leak detection is applied.
AF pipe solutions provides extensive documentation to the customer for installation of the pipe spools. The unique procedures provided by AF Pipe solutions deliver an added value to the project. The pipe spools are welded together with this unique guidance, and special tooling only available from AF Pipes. The piping arrangement is to be designed carefully in accordance with the pipe support specifications in order to achieve a robust double wall pipe design.
