Record 1 1990-01-23

English

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
DEF

Boiler constructed of ferrous or nonferrous metal in which the maximum allowable gauge working pressure is limited to 15 psi for steam and 160 psi at 250 F for hot-water heating boilers.

DEF

... boiler constructed for maximum working pressures of 103 kPa (15 psi) steam and up to 1103 kPa (160 psi) hot water.

Key term(s)
  • LP boiler

French

Domaine(s)
  • Fours et chaudières (Chauffage)
CONT

Chaudière basse pression et haute pression. Le chauffage est dit basse pression si la pression de vapeur au départ de la chaudière ne dépasse pas 3 000 mm CE (0,3 bar). En réalité, la pression de vapeur, d'autant plus élevée que l'installation est plus étendue dans le sens horizontal, atteint rarement cette limite (pour 30 m : 500 mm CE, pour 200 m : 1 000 mm CE).

CONT

Chaudières à basse pression [...] sont de deux types différents: 1. Chaudières en tôle d'acier; 2. Chaudières en fonte.

CONT

Where a steel or aluminium self-contained breathing apparatus cylinder has a dent deeper than 1. 5 mm and greater than 50 mm in major dimensions or shows evidence of deep isolated pitting, cracks or splits, the cylinder shall be removed from service until it has been shown to be safe for use by a hydrostatic test at a pressure equal to one and one-half times the maximum allowable working pressure.

OBS

"Maximum allowable working pressure" is standardized by ISO.
