Standard About Insulated Flange.

Insulated flangendi chipangizo cholumikizira chomwe chimagwiritsidwa ntchito m'mapaipi, chomwe chimakhala ndi mawonekedwe odzipatula kapena kutentha. Zotsatirazi ndizomwe zimayambira pa ma insulated flanges:

Kukula

Miyeso yodziwika bwino imaphatikizapo zosiyana siyana monga DN15 mpaka DN1200, ndipo kukula kwake kumayenera kusankhidwa kutengera kagwiritsidwe ntchito ndi miyezo yeniyeni.

Kupanikizika

Kugwira ntchito kwamphamvu kwa ma flanges opangidwa ndi insulated kumatengera zida zawo zopangira komanso momwe amapangira. Nthawi zambiri, imatha kukwaniritsa zofunikira zina zapantchito, monga miyezo wamba monga PN10 ndi PN16.

Gulu

Ma flanges opangidwa ndi insulated amatha kugawidwa m'mitundu yosiyanasiyana kutengera kapangidwe kawo ndi ntchito, monga:

1. Bolted flange: yolumikizidwa ndi mabawuti, oyenera kulumikizana ndi mapaipi ambiri.

2. Kuwotcherera flange: Kulumikizidwa ndi kuwotcherera, komwe kumagwiritsidwa ntchito kwambiri m'malo otentha komanso opanikizika kwambiri.

3. Mpira flange: Kugwiritsa ntchito mphira kapena zotchingira zina, zoyenera nthawi zomwe zimafuna kudzipatula kwamagetsi kapena kutentha.

Mawonekedwe

1. Kuchita kwa insulation: Chinthu chachikulu ndikutha kudzipatula bwino panopa kapena kutentha, kuteteza kusokoneza ndi kuwonongeka.

2. Kulimbana ndi dzimbiri: Zopangidwa ndi zinthu zosagwirizana ndi dzimbiri, zoyenera kumalo ochita dzimbiri monga engineering yamankhwala.

3. Kuyikirako kosavuta: Nthawi zambiri kumamatira kapena kuwotcherera kuti muyike mosavuta.

Ubwino ndi kuipa kwake

Ubwino

Amapereka kudzipatula kwamagetsi ndi kutentha, koyenera malo apadera; Kukana kwa dzimbiri kwabwino; Zosavuta kukhazikitsa.

Kuipa

Mtengo wake ndi wokwera; M'madera ena omwe ali ndi mphamvu zambiri komanso kutentha kwambiri, mapangidwe ovuta angafunike.

Kuchuluka kwa ntchito

Ma flanges opangidwa ndi insulated amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza koma osalekezera ku:

1. Makampani opanga mankhwala: Makina a mapaipi omwe amafunikira kutchinjiriza kwa media media.

2. Makampani opanga magetsi: M'malo omwe magetsi akufunika, monga kulumikiza chingwe.

3. Makampani opanga zitsulo: Kulumikizana kwa mapaipi kumalo otentha kwambiri komanso opanikizika kwambiri.

4. Magawo ena ogulitsa: nthawi zokhala ndi zofunikira zapadera pamayendedwe aposachedwa kapena kutentha.

Posankha ma flange otsekera, ndikofunikira kudziwa mtundu woyenera ndi mawonekedwe ake potengera momwe amagwiritsidwira ntchito, mawonekedwe apakatikati, ndi momwe amagwirira ntchito.

Mayeso okhwima

1.Malumikizidwe otsekera ndi ma flanges otsekereza omwe adutsa mayeso amphamvu ayenera kuyesedwa kuti azitha kulimba m'modzi ndi m'modzi pa kutentha kozungulira kosachepera 5 ° C. Zofunikira zoyesa ziyenera kukhala molingana ndi zomwe GB 150.4.

2.Kuthamanga kwa mayeso olimba kuyenera kukhala kokhazikika kwa mphindi 30 pa 0.6MPa kuthamanga ndi mphindi 60 pakupanga mapangidwe. Njira yoyesera ndi mpweya kapena gasi wolowera. Palibe kutayikira kumatengedwa kuti ndi koyenera.
