Iiklasi zoxinzelelo lweeFlanges
Iiflange zentsimbi ezibunjiweyo ze-ASME B16.5 zenziwe kwiiKlasi zoxinzelelo eziphambili ezisixhenxe:
150
300
400
600
900
1500
2500
Ingqikelelo ye-flange yokulinganisa ithanda ngokucacileyo. I-Flange ye-Class 300 inokusingatha uxinzelelo olungaphezulu kune-Class 150 flange, kuba i-Class 300 flange yakhiwe ngentsimbi eninzi kwaye inokumelana noxinzelelo olungakumbi. Nangona kunjalo, kukho inani lezinto ezinokuchaphazela amandla oxinzelelo lweflange.
Ukutyunjwa koxinzelelo loxinzelelo
Inqanaba loxinzelelo lweeflange liya kunikwa kwiiKlasi.
Iklasi, elandelwa linani elingenamda, kukuchongwa kweereyithingi zoxinzelelo lobushushu ngolu hlobo lulandelayo: Udidi 150 300 400 600 900 1500 2500.
Amagama ahlukeneyo asetyenziswa ukubonisa iKlasi yoxinzelelo. Umzekelo: 150 Lb, 150 Lbs, 150# okanye Class 150, zonke zithetha into enye.
Kodwa kukho enye kuphela isalathisi esichanekileyo, kwaye yiKlasi yoxinzelelo, ngokutsho kwe-ASME B16.5 iqondo loxinzelelo linani elingenamda.
Umzekelo woxinzelelo loxinzelelo
Iiflange ziyakwazi ukumelana neengcinezelo ezahlukeneyo kumaqondo obushushu ahlukeneyo. Njengoko izinga lokushisa linyuka, ukulinganiswa koxinzelelo lweflange kuncipha. Umzekelo, i-Class 150 flange ilinganiswe malunga ne-270 PSIG kwiimeko ze-ambient, i-180 PSIG malunga ne-400 ° F, i-150 ye-PSIG malunga ne-600 ° F, kunye ne-75 PSIG malunga ne-800 ° F.
Ngamanye amazwi, xa uxinzelelo lwehla, iqondo lokushisa liyenyuka kwaye ngokuphambene. Izinto ezongezelelweyo kukuba i-flanges inokwakhiwa kwizinto ezahlukeneyo, ezifana nensimbi engenasici, isinyithi kunye ne-ductile iron, i-carbon steel njl.
Ngezantsi komzekelo weflangeNPS 12kunye neeklasi ezininzi zoxinzelelo. Njengoko ubona, ububanzi obungaphakathi kunye nobubanzi bobuso obuphakanyisiweyo ngokufanayo; kodwa i-diameter yangaphandle, isangqa sebholiti kunye nedayamitha yemingxuma yebholiti iba nkulu kwiklasi nganye yoxinzelelo oluphezulu.
Inani kunye needayamitha (mm) zemingxuma yeebholithi zezi:
Iklasi 150: 12 x 25,4
Iklasi 300: 16 x 28.6
Iklasi 400: 16 x 34.9
Iklasi 600: 20 x 34.9
Udidi 900: 20 x 38.1
Iklasi 1500: 16 x 54
Iklasi 2500: 12 x 73
Amanqaku oxinzelelo lobushushu – Umzekelo
Iqondo lobushushu boxinzelelo lolona xinzelelo luphezulu oluvumelekileyo lwegeyi yokusebenza kwiiyunithi zebha kumaqondo obushushu kwiidigri zecelsius. Kumaqondo obushushu aphakathi, i-linear interpolation ivumelekile. Ukudityaniswa phakathi kobizo lweklasi akuvumelekanga.
Iqondo lobushushu boxinzelelo loxinzelelo lisebenza kumalungu e-flanged ahambelana nemida kwi-bolting kunye ne-gaskets, eyenziwe ngokuhambelana nokusebenza kakuhle kokulungelelaniswa kunye nokuhlanganisa. Ukusetyenziswa kwezi zilinganiso kumalungu aneflanged angahambelani nale mida luxanduva lomsebenzisi.
Iqondo lokushisa eliboniswe kwiqondo loxinzelelo oluhambelanayo liqondo lokushisa kwegobolondo elinoxinzelelo lwecandelo. Ngokubanzi, obu bushushu buyafana nolwelwelo olukhoyo. Ukusetyenziswa komlinganiselo woxinzelelo ohambelana neqondo lobushushu ngaphandle kwelo lolwelo oluqulethwe luxanduva lomsebenzisi, ngokuxhomekeke kwiimfuno zeekhowudi kunye nemimiselo esebenzayo. Kuwo nawaphi na amaqondo obushushu angaphantsi kwe -29°C, umlinganiselo awuyi kuba mkhulu kunomlinganiselo obonisiweyo we -29°C.
Njengomzekelo, ngezantsi uya kufumana iitheyibhile ezimbini ezinamaqela ezinto ze-ASTM, kunye nezinye iitafile ezimbini ezine-flange zoxinzelelo-ubushushu bomgangatho wezo zinto ze-ASTM ASME B16.5.
