Sisitemu ya Flange Sisitemu
Piping flange bivuga flange ikoreshwa muguhuza imiyoboro mugushiraho imiyoboro, kandi yerekeza kumurongo winjira no gusohoka wibikoresho iyo bikoreshejwe mubikoresho. Hano hari ibyobo kuri flanges, na bolts bituma flanges ebyiri zihuza cyane. Fanges ifunze hamwe na gasketi. Ikibumbano kigabanijwemo umurongo uhujwe (guhuza urudodo) flange, gusudira flange na clamp flange. Flanges ikoreshwa kubiri, flanges ya wire irashobora gukoreshwa mumiyoboro yumuvuduko muke, hamwe na flanges yo gusudira kumuvuduko wibiro birenga bine. Igicupa cyongewemo hagati ya flanges zombi hanyuma kigakomera hamwe na bolts. Ubunini bwa flanges hamwe ningutu zitandukanye buratandukanye, kandi bolts bakoresha nayo iratandukanye. Iyo pompe zamazi hamwe na valve bihujwe numuyoboro, ibice byibi bikoresho nibikoresho bikozwe muburyo bwa flange bihuye, nabyo bita flange ihuza. Ibice byose bihuza bihujwe na bolts kuruhande rwindege ebyiri kandi bigafungirwa icyarimwe byitwa "flanges", nko guhuza imiyoboro ihumeka. Ubu bwoko bwibice bushobora kwitwa "ibice bya flange". Nyamara, iyi sano ni igice cyibikoresho gusa, nko guhuza flange na pompe yamazi, ntabwo ari byiza kwita pompe yamazi "ibice bya flange". Utuntu duto, nka valve, dushobora kwitwa "ibice bya flange".
. gusudira flange (SW), butt welding impeta irekuye (PJ / SE), impeta yo gusudira impeta irekuye (PJ / RJ), igipfundikizo cya flange (BL (S)), Igipfukisho cya Flange (BL).
2. Ukurikije inganda zikomoka kuri peteroli (SH): urwego rudodo (PT), urudodo rwo gusudira (WN), flange yo gusudira (SO), flake yo gusudira (SW), flange irekuye (LJ), Igifuniko cya Flange (nticyerekanwa ).
3. Ukurikije imashini (JB) ibipimo ngenderwaho byinganda: flange integral, butt welding flange, plaque welding flange flange, butt welding ring plate plate flange flange, plaque welding ring plaque flange flange, flange flange flange flange Flange, igifuniko cya flange.
4. , isahani yo gusudira iringaniye isahani irekuye, impeta y'impeta irekuye, ibipfukisho bya flange.
WCB. C12 (9% chromium na 1% molybdenum), CA6NM (4 (ibyuma bya chromium 12%), CA15 (4) (12% chromium), CF8M (316 ibyuma) (Haast Nickel Alloy B), CW6M (Hasta Nickel Alloy C), CY40 (Inconel) Tegereza.
Ibikorwa byo kubyaza umusaruro bigabanijwemo ubwoko bune: guhimba, guta, gukata no kuzunguruka.
(1) Fata flange na flange mpimbano
Ikibaho cya flange gifite imiterere nubunini nyabyo, ingano ntoya yo gutunganya nigiciro gito, ariko ifite inenge (pore, ibice, inclusitions); imiterere yimbere ya casting irakennye muburyo bworoshye (niba ari igice cyo guca, umurongo ni mubi);
Impimbano mpimbano muri rusange ifite karubone nkeya kuruta flanges kandi ntabwo byoroshye kubora. Kubabarirwa byoroheje, bifite imiterere yuzuye, kandi bifite imiterere yubukanishi kuruta flanges;
Inzira yo guhimba idakwiye nayo izatera ibinyampeke binini cyangwa bitaringaniye, gukomera, hamwe nigiciro cyo guhimba kirenze flanges.
Kubabarirwa birashobora kwihanganira inkweto ndende nimbaraga zikomeye kuruta guterana.
Ibyiza bya casting nuko bashobora kubyara imiterere igoye kandi igiciro gito;
Ibyiza byo kwibagirwa nuko imiterere yimbere ari imwe, kandi nta nenge mbi zangiza nka pore na inclusion muri casting;
Uhereye kubikorwa byo gukora, itandukaniro riri hagati ya flange ya flange na flange yahimbwe iratandukanye. Kurugero, centrifugal flange ni ubwoko bwa cast flange.
Centrifugal flanges nuburyo bwo gutara neza kugirango butange flanges. Ugereranije no guta umucanga usanzwe, imiterere yubu bwoko bwa casting ni nziza cyane, kandi ubwiza buratera imbere cyane. Ntabwo ikunda guhura nibibazo nkimiterere idahwitse, imyenge, na trachoma.
Mbere ya byose, dukeneye gusobanukirwa uburyo flang ya centrifugal ikorwa, uburyo bwo gutunganya nibicuruzwa bya centrifugal casting kugirango ikore flangine yo gusudira, irangwa nuko ibicuruzwa bitunganywa muburyo bukurikira:
Shira ibyuma byatoranijwe byatoranijwe mu itanura rito hagati y’amashanyarazi kugirango ushongeshe, kugirango ubushyuhe bwibyuma bishongeshe bigere kuri 1600-1700 ℃;
Shyushya icyuma kugeza 800-900 ℃ kugirango ubushyuhe buhoraho;
③ Tangira centrifuge, hanyuma usukemo ibyuma bishongeshejwe mu ntambwe ① mu cyuma nyuma yo gushyushya intambwe ②;
Kasting isanzwe ikonjeshwa kugeza 800-900 ℃ ikabikwa muminota 1-10;
Gira amazi hamwe nubushyuhe busanzwe, demould hanyuma ukuremo casting.
