Standard About Insulated Flange

Insulated flange ndi chipangizo chomwe chimagwiritsidwa ntchito kulumikiza ma flanges awiri pamapaipi.Cholinga chake chachikulu ndikuwonjezera chotchinga pakati pa ma flanges kuti muteteze kutentha, komweko, kapena mphamvu zina kuti zisayendetse pamalo olumikizirana ndi flange.

Mapangidwewa amathandizira kuchepetsa kutayika kwa mphamvu, kukonza chitetezo chadongosolo, ndipo ndi oyenera kugwiritsa ntchito zomwe zimafunikira kupewa kutayikira kwapakatikati, kutentha kwa insulation, kapena kutsekereza magetsi.

Zofunikira zazikulu ndi ntchito:

1.Insulation material: Insulation flanges nthawi zambiri imagwiritsa ntchito zipangizo zomwe zimakhala ndi ntchito yabwino, monga mphira, pulasitiki, kapena fiberglass, monga chigawo chosungira.Zidazi zimatha kusiyanitsa bwino mphamvu zamagetsi monga kutentha ndi magetsi.

2.Kuletsa kuyendetsa mphamvu: Ntchito yaikulu ya ma flanges otetezedwa ndi kuteteza mphamvu kuti isayendetse pamtunda wa kugwirizana kwa flange.Izi ndizofunikira kwambiri pakutchinjiriza kwamafuta, kutchinjiriza kwamagetsi, kapena kutchinjiriza mphamvu zina pamapaipi.

3.Kuletsa kutayikira kwapakatikati: Flange yotsekeredwa imapanga wosanjikiza wotsekedwa pakati pa ma flanges, omwe amatha kuteteza bwino kutayikira kwapakatikati pamapaipi ndikuwongolera chitetezo chadongosolo.

4.Zoyenera kutentha ndi zovuta zosiyanasiyana: Mapangidwe a insulated flange amasinthasintha ndipo amatha kusinthasintha kuti agwiritse ntchito pansi pa kutentha ndi kupanikizika kosiyanasiyana.Izi zimamupangitsa kuti azigwira ntchito m'mafakitale osiyanasiyana.

5.Easy kukhazikitsa ndi kusamalira: Ma flanges osakanizidwa amakhala ndi dongosolo losavuta, zomwe zimapangitsa kuti zikhale zosavuta kuziyika ndi kuzisamalira.Izi zimathandiza kupititsa patsogolo kayendetsedwe ka kayendedwe ka mapaipi.

6.Kugwiritsidwa ntchito kwambiri: Ma flanges opangidwa ndi insulated amagwiritsidwa ntchito kwambiri mu machitidwe a mapaipi m'mafakitale monga petroleum, mankhwala, mphamvu, ndi kutentha, makamaka panthawi yomwe mphamvu yowonjezera imafunika.

Mayeso okhwima

1. Malunjidwe otsekereza ndi ma flanges otsekereza omwe adapambana mayeso amphamvu ayenera kuyesedwa ngati kulimba m'modzi ndi m'modzi pa kutentha kozungulira kosachepera 5 ° C.Zofunikira zoyeserera ziyenera kukhala molingana ndi zomwe GB 150.4.
2. Kupanikizika koyezetsa kolimba kuyenera kukhala kokhazikika kwa mphindi 30 pa kuthamanga kwa 0.6MPa ndi mphindi 60 pakukakamiza kwa mapangidwe.Njira yoyesera ndi mpweya kapena gasi wolowera.Palibe kutayikira kumatengedwa kuti ndi koyenera.

Tiyenera kudziwa kuti ma flanges osiyanasiyana otsekeredwa amatha kukhala oyenera malo osiyanasiyana komanso momwe amagwirira ntchito.Choncho, posankha ndi kugwiritsa ntchito flanges insulated, m'pofunika kupanga zisankho zoyenera malinga ndi zofunikira za ntchito ndi mmene ntchito dongosolo mapaipi.
