GALVANIZED REDUCER GZ 11/4"x 3/4'' GW REDUCER GALVANIZED 5/4x3/4 DN32/20 AGAFLEX

✴️ GALVANIZED CAST IRON FITTINGS:

✅ Malleable Cast Iron Threaded Pipe Fittings are universal liquid and gas transfer fittings designed to connect threaded components with ISO 7-1 threads, ranging in size from 1/8" to 4".

✅ The external threads are tapered and the internal threads are cylindrical.

✅ The threads of jam nuts and coupling nuts comply with the PN-EN ISO 228 standard. The fittings themselves comply with the PN-EN 10242 standard – entitled "Threaded pipe fittings made of malleable cast iron".

✅ Fittings of all sizes are suitable for operation at the highest permissible operating pressures in the temperature ranges specified in the table below.

✅ Intermediate pressures permissible for operating temperatures between 120°C and 300°C are obtained by linear interpolation.

✅ In the normal use of fasteners, the lowest operating temperature is –20 °C.

✴️ Malleable black cast iron EN-GJMB 350-10 complies with the PN-EN 1562:2012 standard entitled "Foundry – malleable cast iron" and is characterized by the following properties:

✔️ tensile strength Rm – 350 MPa,

✔️ yield strength Re – 200 MPa,

✔️ elongation A – 10 %,

✔️ hardness (tested by the Brinell method) – 170 HB.
