Weld Neck Flanges ndi Slip Pa Flanges--BS3293

British Standard BS 3293: 1960-Carbon Steel Pipe Flanges (kuposa mainchesi 24 kukula mwadzina) kwa Makampani a Petroleum, amakhudza Class 150lb mpaka 600lbweld khosi flangesndikutsetsereka pa flanges.

Zotsatirazi zidzawonetsa miyeso ndi kulolerana kwakuwotcherera khosi flange ndi khosi lathyathyathya kuwotcherera flangeku BS3293.

BS3293 weld khosi ndi kuzembera pa flange ndi American muyezo flange dongosolo muyezo.Ndi chiwonetsero cha American standard flange (yomwe imadziwikanso kuti njira ya ANSI) ndi imodzi mwama flanges omwe amagwiritsidwa ntchito kwambiri pazida kapena mapaipi.

BS 3293:1960 ndi zinthu ndi kukula.Muyezo uwu umagwira ntchito pazitsulo za carbon carbonKulowa-pa flange ndi welded khosi flange wa mwadzina awiri26 mainchesi ndi kukulirapo kwa petroleumIndustrial kubowola, bolting, kumaliza ndi makulidwe
Miyezo imagwiranso ntchito ku mbali zonse.
Flanges kwa ma valve ndi zopangira.Mitundu inayi ya flanges imaperekedwa, yomwe ndi class150, 300, 400 ndi 600. BS 3293: 1960 sichiphatikizapo: kupanikizika / kutentha;Dzina la flange limagwiritsidwa ntchito pozindikiritsa
Zolozera pamtanda zokha: BS 1503, BS 1560, BS 1750, BS 3351, ANSI B16.20, ASTM A 105

Kusiyana pakati pa Weld Neck Flanges ndi Slip On Flanges
1. Mitundu yosiyanasiyana ya weld:
Kuyang'ana kwa radiographic kumatha kuchitidwa chifukwa cha ma welds a khosi la khosi, koma osati pakhosi lathyathyathya.The kuwotcherera mawonekedwe a khosi matako-kuwotcherera flange ndi chitoliro ndi circumferential kuwotcherera, pamene kuwotcherera mawonekedwe lathyathyathya kuwotcherera flange ndi chitoliro ndi fillet weld.Kuwotcherera matako ndi chozungulira chozungulira, ndipo kuwotcherera kosalala ndi ma weld awiri ozungulira.Kusiyana pakati pa awiriwa ndi kuti kuwotcherera kulumikiza khosi matako-kuwotcherera flange ndi nozzle ndi Class B msoko, pamene kuwotcherera kulumikiza khosi matako-kuwotcherera flange ndi nozzle ndi Class C msoko.
2. Zida zosiyanasiyana:
Zomwe zimapangidwa ndi khosi lachitsulo chowotcherera flange nthawi zambiri zimapangidwa ndi zida zachitsulo zopangidwa ndi makina.Zinthu za slip-on kuwotcherera flange ndi khosi amapangidwa wamba zitsulo mbale ndi makulidwe chofunika kudzera Machining.
3. Makakamizo osiyanasiyana mwadzina:
Kuthamanga mwadzina kwa khosi la matako-kuwotcherera flange ndi 1-25MPa, komwe kuli kokwezeka.Kuthamanga mwadzina kwa khosi lathyathyathya kuwotcherera flange ndi 0.6-4MPa.Poyerekeza ndi khosi lathyathyathya kuwotcherera flange, kupanikizika kwake kumakhala kochepa ndipo kuthekera kwake kuti agwirizane ndi kupanikizika kumatsikanso.
