Secondary surface (fins) are of the plate-fin design using aluminum or copper, with die-formed collars. The fin design is to be flat, waffle, or sine-wave in a staggered tube pattern to meet performance requirements.
Our standard steam coils are built with 5/8“ tubes and standard .025” wall thickness. Available with opposite or same end connections, our steam coils are designed to withstand up to 150 psig saturated steam supply pressure.
Casing
Coil casing material shall be of G90 galvanized steel, 16 gauge minimum. Heavier material, stainless steel, copper, or aluminum casings are to be provided as required. All tube sheet holes are to be oversized to allow for free thermal expansion and contraction of tubes during operation. Intermediate tube supports are to be provided on all coils 50” and longer in fin length. Coil casings on the top and bottom of coils are to have double-flanged construction, allowing for vertical stacking of coils.
Tubes
Tubes and return bends are to be constructed from seamless UNS C12200 copper conforming to ASTM B224 and ASTM E527. Properties shall be O50 light annealed, with a maximum grain size of 0.040mm. Seamless tubes are to be mechanically expanded into plate fins to form an everlasting bond between primary and secondary surfaces.
Pressure Testing
Coils shall be tested at 550 PSIG using dry nitrogen, submerged underwater. Dual-operator verification shall determine that all coils are leak-free
