Galvanised Malleable Iron Pipe Fittings — Screwed BSP Fittings for Industrial Pipework
Malleable iron pipe fittings are screwed threaded fittings for low-to-medium pressure pipework systems in compressed air, water, gas and steam distribution. AIMS Industrial stocks a range of galvanised malleable iron fittings from AAP and Dixon — including elbows, sockets, reducing sockets, flanges, plugs and pipe in BSP (British Standard Pipe) parallel and taper thread.
What is Malleable Iron?
Malleable iron is cast iron that has been heat-treated (annealed) to improve ductility and impact resistance relative to standard grey cast iron. This makes malleable iron fittings suitable for pipework that may experience vibration, thermal cycling or minor mechanical stress — where brittle grey iron would crack. Galvanised (zinc-coated) fittings provide corrosion protection for compressed air and water service.
The Range
AAP malleable iron fittings cover the core screwed fitting types: elbows (90° for direction changes), sockets (straight couplings and reducing sockets for joining pipes of different sizes), flanges (oval and round, for bolted connections to equipment and vessels), and square head plugs (for closing off pipe ends and test points). Dixon fittings cover additional configurations including screwed round flanges drilled to table D for bolted flange connections.
BSP Thread
All fittings are BSP threaded — the dominant thread standard for industrial and commercial pipework in Australia. BSP (BSPP — parallel) and BSPT (taper) are both used; check the fitting and pipe thread type before assembly. PTFE thread tape is the standard sealant for BSP parallel thread connections.
Applications
Typical applications include compressed air distribution systems, fire protection water mains, steam distribution at low pressures, gas pipework, and general industrial water service. Always verify the pressure rating of the fitting for the specific service — standard malleable iron fittings are rated to approximately 14 bar for water and air service at ambient temperature.
