Zopangira Mapaipi a Threaded

Zopangira mapaipi a ulusi zimagwiritsidwa ntchito pamapaipi pomwe akugwirizana makina ulusiimakonda kuposa kuwotcherera, makamaka m'mizere ing'onoing'ono-yolumikiza zida, nthambi zantchito, ma drain ndi polowera polowera, komanso kukonza{1}}zomanga. Kwa zopangira zitsulo zopangira, maziko odziwika bwino ndiASME B16.11, zokhala ndi ulusi mapeto zilipoNPT, BSPT, kapena BSPP, kawirikawiri chophimba1/8 "mpaka 4"ndi makalasi opanikizika mongaKalasi 2000, 3000, ndi 6000.

Cholumikizira cha ulusi sichiyenera kugulidwa ndi mawonekedwe okha. Mfundo zitatu zomwe zimalamulira kuvomereza ndimtundu wa ulusi, kalasi ya pressure,ndizinthu kalasi.

Mtundu wa ulusiziyenera kufanana ndi zojambula za polojekiti ndi msika wolandirira:

• Mtengo wa NPTamagwiritsidwa ntchito kwambiri ku North America mafuta, gasi, ndi mafakitale wamba.
• Mtengo wa BSPTndi ulusi wopendekera ndipo umagwiritsidwa ntchito kwambiri m'misika yambiri yotumiza kunja.
• BSPPndi ulusi wofanana ndipo nthawi zambiri umafunika makina osindikizira, gasket, kapena O-kupanga mphete m'malo mosokoneza ulusi wokha.

Kalasi yokakamizaziyenera kufananizidwa ndi mizere yamapangidwe:

• Gawo la 2000
• Gawo la 3000
• Gawo la 6000

Zosankha zakuthupinthawi zambiri amasankhidwa ndi chikhalidwe chautumiki:

• Chithunzi cha ASTM A105ntchito zonse za carbon steel
• Chithunzi cha ASTM A350 LF2za -zotentha pang'ono
• ASTM A182 F304 / F316za ntchito zosavunda-
• ASTM A182 F11 / F22 / F91zamakina okwera-amatenthedwe a aloyi

Kwa ogula akufufuzatchati cha miyeso ya mitope ya ulusi, zomwe zili zofunika kwambiri patsamba sizomwe zili patsamba-zokhala ndi manambala okopera. Njira yothandiza ndiyo kuwonetsakusankha osiyanasiyanandi kufotokoza kuti malo enieni-ku-kumapeto ndi ulusi wa geometry amatsimikiziridwa motsutsaASME B16.11ndi muyezo wa ulusi wotchulidwa.

Kwa miyeso yeniyeni, ndemanga kapena zojambulazo ziyenera kutsimikizira:

• mtundu woyenera
• kukula mwadzina
• kalasi ya pressure
• ulusi muyezo
• zinthu kalasi

A kulumikiza chitoliro cha ulusindi imodzi mwamapaipi ang'onoang'ono-amene amayitanidwa. Imagwiritsidwa ntchito kulumikiza zitoliro ziwiri zowongoka mowongoka ndipo nthawi zambiri zimawoneka pamakina othandizira, nthambi za zida, phukusi la skid, ndi ntchito yosinthira.

Kuchokera pamawonedwe ogula, macheke ofunikira pakulumikiza mapaipi a ulusi ndi awa:

• ulusi muyezo: NPT, BSPT, kapena BSPP
• kalasi ya pressure: 3000 kapena 6000 ndizofala pa-ntchito zazing'ono
• zinthu kalasiA105, LF2, F304, F316, etc.
• makina khalidwe: mbiri yoyera ya ulusi ndikuvomereza koyenera
• kutsatira: kuyika chizindikiro ndi MTR yolumikizidwa ndi nambala ya kutentha

Kulumikizana kwa chitoliro cha ulusi kumamveka mophweka, koma ngati ulusiwo uli wolakwika, gawolo limakhala losagwiritsidwa ntchito pamalopo. Ndicho chifukwa chake maulamuliro ophatikizana ayenera kulembedwa nthawi zonse mumtundu wa PO, monga:
