STEAM COIL SPECIFICATIONS

1.Product Overview

Standard steam coils can be used in applications where freezing is not a concern and on-off steam control valves are utilized. Steam distributing coils are used when near freezing air conditions exist or when modulating control valves are used.

2.Design Pressures & Temperatures

Coils are designed for 150 psi maximum operating pressure and maximum steam temperature of 365° F.

3.Fin Materiall

Coils are constructed with plate fin, die-formed aluminum or copper with self spacing collars. Standard aluminum material thickness shall be .0075 +/- 5% and standard copper material thickness shall be .006 +/- 5% unless otherwise specified.

4.Tube Material

All tubing and return bends are manufactured with seamless copper conforming to ASTM B75 and ASTM B251. Tubes are mechanically expanded to form an interference fit with fin collars.

Manifold Material

All manifolds are constructed from seamless copper conforming to ASTM B75 and ASTM B251. Each return manifold has a factory installed air vent located at the highest point on the face of the manifold. All core tubes evenly protrude into the inside diameter of the manifold no more than a 1/8”.

6.Brazing

All brazed joints utilize high temperature filler metals. Manifold connections are brazed with filler metal containing at least 5% silver.

7.Casing Material

Casing and tube sheets are manufactured from 16 gauge galvanized steel, meeting ASTMA527 standards. Coils up to ten feet will have a pitched casing toward the condensate connection, a minimum of 1/8” per foot. Coils over ten feet in length should be pitched at time of installation to ensure proper condensate removal.

8.Testing Requirements

Coils are pressurized with a minimum of 315 psi air pressure and completely submerged in water.
