Details
A ductile iron wide tolerance stepped coupling imhando yekubatanidza inoshandiswa kubatanidza mapaipi maviri kana mafittings ehukuru hwakasiyana.Yakagadzirwa nesimbi inoputika, inova rudzi rwesimbi yakakandwa inoshanduka uye yakasimba kudarika simbi yechinyakare.
Iyo yakakura kushivirira dhizaini yekubatanidza inobvumira huwandu hukuru hwepombi saizi kuti ibatane, kuderedza kudiwa kweakawanda couplings uye fittings.Iyo yakatsika dhizaini yekubatanidza inopa yakachengeteka uye yakasimba kukwana pakati pemapombi, kuve nechokwadi chekubatanidza-isina kubuda.
Ductile iron wide tolerance stepped couplings inowanzo shandiswa mumvura netsvina yekuchenesa zvidyarwa, pamwe nemumaindasitiri ekushandisa senge oiri uye gasi mapaipi.Iwo anoshandiswawo mupombi dzemvura uye HVAC masisitimu ekubatanidza mapaipi ehukuru hwakasiyana.
Pakazere, ductile iron yakafara kushivirira yakatsika ma couplings mhinduro yakavimbika uye inodhura-inoshanda yekubatanidza mapaipi ehukuru hwakasiyana, ichipa yakachengeteka uye isina kuvuza yekubatanidza iyo inogona kumirisana nezvinodiwa zveakasiyana maapplication.
