12kW boilers, first boiler use a 22mm elbow to the second boiler. Second boiler tee 22mm in from first boiler, 22mm branch to second boiler, 28mm to third boiler. Third boiler tee 28mm in from second boiler, 22mm branch to third boiler, 35mm away to heating circuit. Repeat for the return connections.
01/01/2016 · If the working temperature of the pipe's wall or the chamber exceeds 570 ÂºC, one then must use highly alloyed steels Cr-Ni or Cr-Ni-Mo austenitic steels (with very low carbon content). 3.2 Seamless steel pipes Those are pipes where the mechanical properties at elevated temperatures are guaranteed, primarily the yield stress; they are aimed for mounting into the boiler installations, or some
