Let's assume for the moment you are looking for a boiler barrel (The barrel is the long'ish, tubular, front part of the boiler). If you run it through the applicable formlae for boiler barrels you will find that Type M is actually sufficiently strong for 100psi steam.
performed periodically to remove sludge from the bottom of the boiler. The importance of boiler blowdown is often overlooked. Improper blowdown can cause increased fuel consumption, additional chemical treatment requirements, and heat loss. In addition, the blowdown water has the same temperature and pressure as the boiler water.
Water-tube boiler – Wikipedia 2018-7-10 · The only railway use of water-tube boilers in any numbers was the Brotan boiler, invented in Austria in 1902 by Johann Brotan and found in rare examples throughout Europe.
Steam Boiler Pressure Gauge and Normal Pressure Ranges. Pressure and Temperature gauge on steam heating boilers: [Click to enlarge any image. Steam heating boiler pressures: Residential steam heating systemsoperate at very low pressures, perhaps around .5 psi - that' s 1/2 of one psi while commercial steam boilers may operate at higher pressures.
The total steam flow relates to certain downcomer flows and pressure drops to ensure adequate cooling of furnace wall panels, etc. Overfiring the boiler results in higher flow rate demands in downcomer circuits which raises the pressure drop, thus impeding flow.

The steam pressure should be allowed to drop naturally without opening vents or other intentional means of taking steam from the unit to hasten the lowering of steam pressure. A cooling rate exceeding 100°F per hour to 150°F per hour by excessive opening of vents should be avoided to limit the drum distortion and resulting strains on tube joints.
