Izinqubo zokushisela i-H-economizer flash resistance ezisetshenziswayo, umthungo wokushisela ngemuva kwezinga eliphezulu lokuhlanganisa, amandla we-weld tensile, futhi unokuguquguquka okuhle okushisayo.I-H-economizer ingakwazi futhi ukukhiqiza amashubhu amabili amashubhu “double H” ohlobo lwe-fin, ukwakheka kwawo okuqinile, futhi ingasetshenziswa enkathini yerowu yeshubhu omude.
