Cast Iron Sectional

Cast-iron boilers may be used in steam heating or hot water heating applications within the scope and service restrictions of ASME Section IV. Section IV service restrictions limit steam boilers to pressures not exceeding 15 psi and hot water boilers to pressures not exceeding 160 psi and/or temperatures not exceeding 250°F. Sectional boilers are typically assembled with tapered connections called push nipples or elastomeric-type gaskets between the sections to seal the water-containing chambers. Another type of assembly uses external headers to connect the water containing chambers.

 


SMITH CAST IRON BOILERS
– Smith Cast Iron Boilers are known throughout North America for their rugged reliability, operating efficiencies and longevity. Our products range from small residential boilers to the largest cast iron commercial boilers available in North America. Typical applications range from homes and apartments up to very large institutional buildings such as schools, universities and government buildings.

All Smith boilers are in compliance with A.S.M.E. standards for safety, and all capacity and efficiency ratings independently I=B=R certified by Hydronics Institute of GAMA.
