TEE COUPLING GW 1 1/2'' DN40 BLACK STEEL CAST IRON AGAFLEX

✴️ BLACK CAST IRON FITTINGS: ✅ Malleable cast iron threaded pipe fittings are universal fittings used for conveying liquids and gases, designed to connect threaded parts with threads according to ISO 7-1, with sizes from 1/8" to 4". ✅ The external threads are tapered and the internal threads are cylindrical. ✅ Threads of counter-nuts, nuts of two-connectors are in accordance with PN-EN ISO 228. The fittings themselves comply with the PN-EN 10242 standard – entitled "Threaded pipe fittings made of malleable cast iron" ✅ Fittings of all sizes are useful for operation at the highest allowable operating pressures in the temperature ranges specified in the table below. ✅ Intermediate values of pressures permissible for operation at 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. Black malleable 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. ✴️
