STANDARD STEAM COIL

---

A Steam Coil looks and operates very much like a hot water coil. It is almost always a 1 or 2-row coil and the steam enters and leaves just like hot water. However, the major difference is in the construction, where the tubes and return bends are heavier wall copper and the brazing process is upgraded. 

It's important to remember that even low-pressure steam is more corrosive than  hot water.  Therefore, a steam coil needs to be built accordingly. 

When you build Standard Steam Coils, you have several options regarding the construction.

• .025 wall copper – low pressure up to 20 p.s.i.g.
• .035 wall copper – medium pressure up to 50 p.s.i.g.
• .049 wall copper – high pressure up to 100 p.s.i.g.
• .035 or.049 cupro/nickel – higher pressure up to 200 p.s.i.g.
• .049 or.065 carbon steel – very high pressures
• .035 or.049 stainless steel – very high pressures

Standard Steam Coils come with 5/8" tubes.
