Cooling is achieved by means of Air Coolers. In this process, the oil is cooled using ambient air. To increase the surface area, fins are applied to the tubes. To enhance heat transfer on the inside, wire mesh inserts are installed within the tubes.
Our customer supplies a number of systems to a major international player in oil and gas via a seal system provider. These coolers are required for this purpose. To fit properly on the skid, the coolers are placed vertically. Due to the low power requirements, a single row of tubes is sufficient. The connection headers are of the manifold type. Welding nipples are milled onto a solid bored bar, to which the tubes are attached by means of an orbital welder with a qualified circumferential weld.
This involves multiple Air Coolers with single or multi-pass high finned (aluminum fins) bundles with manifold type headers, type MHFM, entirely in stainless steel according to PED cat.II/Mod A2 or cat.III/mod.H, ASME VIII Div.1 and API 682.
