Galvanised Malleable Iron Pipe Fittings

STANDARD AND IDENTIFICATION:

• Standard for production and use EN 10242: 1994

• Fittings made of high-quality blackheart malleable cast iron to ASTM A-197, ASTM A47

THREADS:

• The threads are cut according to AS 1722.1 / ISO 7/1. Parallel internal thread (RP) and tapered external thread (R).

APPLICATION:

• All the fittings are adequate for the supply of water at the recommended maximum working pressure of 1379kPa and gas, steam, and compressed air at the recommended maximum working pressure of 1034 kPa.
• Note: Working pressures may also be limited by relevant pressure piping codes or Industry regulations.

DIMENSIONS:

• All the fittings are manufactured to the speci?cations of standard BS EN 10242, BS 143, BS 1256

INSPECTION:

• All the fittings are inspected for conformity with the speci?cations of standard EN 10242.
