Selection guidance
Frequently asked questions.
Can the B2 be used with a model steam engine?
The B2 is designed as a standalone model steam boiler for a compact miniature steam-engine installation.
What is included with the B2?
The product page describes brass fittings, copper pipework, a pressure gauge and valve hardware. Request current specification details for your intended installation.
How is hydrostatic pressure testing performed on miniature model steam boilers?
Hydrostatic testing fills the boiler completely with ambient water and applies hydraulic test pressure (typically 1.5 to 2 times working pressure) via a hand test pump to verify shell and joint integrity without compressed air hazards.
What safety valve setting and maintenance are recommended for miniature brass boilers?
Safety valves should be set to release at 2.5–3 bar (approx. 2.5–3 kg/cm²). Regular inspection ensures free valve movement, clean seating surfaces, and accurate pressure gauge calibration.
