Malleable iron has long been a staple in plumbing and pressure applications, prized for its unique balance of strength and resilience. by undergoing a heat treatment process, malleable iron retains the durability of cast iron while reducing its natural brittleness, making it an ideal choice for pipe fittings that must endure high pressure without cracking.

Pdf Bs En 10242 Threaded Pipe Fittings In Malleable Cast Iron Malleable iron pipe fittings are metal fittings designed to connect and secure pipework. topics covered in this guide. modern life relies on water and gas supply as well as sewage and wastewater removal, and underground piping supports these mechanisms. in industry, gases and liquids are moving around plants and factories through pipework, too. Following standards are used for designing threaded pipe fittings. asme b16.11: forged fittings, socket welding, and threaded. mss sp 83: class 3000 steel pipe unions, socket welding, and threaded; asme b16.3: malleable iron threaded fittings; asme b16.4: gray iron threaded fittings; asme b16.39: malleable iron threaded pipe unions. The l1 basic hand tight engagement applies to nptf threads. it is the theoretical length of assembly (hand tight) if both parts had perfect thread form and taper and were exactly at the nominal size. the diagram and table below show standard l1 lengths (hand tight engagement) for pipe threads as well as the l3 (wrench make up). Malleable iron is known for its versatility and ductility. it undergoes a heat treating process, enhancing its ability to withstand high pressures and temperatures. this flexibility makes it ideal for fittings requiring precise adjustments and configurations. cast iron, in contrast, is valued for its strength and durability.

Again, this is a threaded fitting, but depending on your use, you could be better off using forged carbon steel if you need to weld it. additionally, fittings made of malleable iron have 150 and 300 pound strength ratings. much less pressure can be applied to a threaded fitting, which has a 3000 and 6000 pound pressure rating. difference. 300# mi screwed fittings have ratings which depend on size and temperature and are much higher than the 150# fittings but lower than those of a105 forged 3000# fittings. they're rare in the local area here and are easily mistaken for the stronger 3000# fittings. we don't use them as a consequence. neither can be welded screwed connections only.
