1.Ose Metric uye Imperial Size Anowanikwa:Chigadzirwa chedu chinowanikwa mune ese metric uye emperial saizi, ichipa kune akasiyana siyana eindasitiri zviyero uye mashandisiro. Uku kuchinjika kunogonesa kuenderana neakasiyana masisitimu madhizaini uye inorerutsa manejimendi ezvinyorwa zvezvirongwa zvepasi rese.
2.SAE Threads:Chigadzirwa chacho chinoratidzira SAE (Society of Automotive Injiniya) tambo, dzinozivikanwa nekurongeka uye kuvimbika. SAE tambo dzinoshandiswa zvakanyanya muindasitiri yeHVACR nekuda kwehukuru hwadzo uye mashandiro ari pasi pemamiriro ekumanikidza. Izvi zvinogonesa yakachengeteka uye inovuza-proof yekubatanidza, yakakosha pakuchengetedza system kutendeseka.
3.Refrigeration Brass Material:Yakagadzirwa kubva kumhando yepamusoro firiji ndarira, chigadzirwa chinopa yakanakisa corrosion kuramba uye kusimba. Brass inosarudzwa mumafiriji maapplication ekupisa kwayo, simba, uye kuramba kupfeka, zvichiita kuti ive yakanakira kushandiswa mukuda nharaunda dzeHVACR.
4.Hapana Brazing Inodiwa:Ichi chigadzirwa chinobvisa kudiwa kwebrazing, kurerutsa kuisa uye kuderedza mari yevashandi. Iyo isina-brazing ficha inosimudzira chengetedzo nekudzikisa njodzi dzine chekuita neyakavhurika murazvo kushandiswa uye inova nechokwadi chekukurumidza, chinoshanda kuseta maitiro. Izvi zvinobatsirawo kuchengetedza kuchena kwehurongwa, sezvo pasina flux kana filler zvinhu zvinounzwa.
