Pipe Flange System
Piping flange inoreva flange inoshandiswa kupinza pombi mukumisikidza pombi, uye inoreva kupinza uye kuburitsa maflange emidziyo kana ichishandiswa pamidziyo.Pane maburi pamaflange, uye mabhaudhi anoita kuti maflange maviri anyatsobatana.Iyo flange yakavharwa negaskets.Iyo flange yakakamurwa kuita threaded connection (threaded connection) flange, welding flange uye clamp flange.Flanges anoshandiswa ari maviri maviri, waya flanges inogona kushandiswa kune yakaderera-kudzvanywa mapaipi, uye welded maflange ekumanikidza anodarika makirogiramu mana.Gasket inowedzerwa pakati pemaflange maviri uye yobva yasimbiswa nemabhaudhi.Ukobvu hwemaflange ane kudzvinyirirwa kwakasiyana kwakasiyana, uye mabhoti avanoshandisa zvakare akasiyana.Kana pombi dzemvura nemavharuvhu zvakabatana nemapaipi, zvikamu zvemidziyo iyi uye midziyo inogadzirwawo kuti ienderane maumbirwo eflange, ayo anodaidzwa kunzi flange connections.Zvose zvinobatanidza zvikamu zvakabatanidzwa nemabhaudhi padivi rendege mbiri uye zvakavharwa panguva imwe chete zvinowanzonzi "flanges", sekubatanidzwa kwepombi dzemhepo.Mhando iyi yezvikamu inogona kunzi "flange zvikamu".Zvisinei, kubatana uku kunongova chikamu chezvigadzirwa, zvakadai sekubatana pakati peflange uye pombi yemvura, hazvina kunaka kudana pombi yemvura "flange zvikamu".Zviduku, zvakadai sevhavha, zvinogona kunzi "flange zvikamu".

4. Zvinoenderana nenyika (GB) zviyero: integral flanges, threaded flanges, butt welding flanges, neck flat welding flanges, neck socket welding flanges, butt welding mhete yemutsipa yakasununguka flanges, plate flat flanges Welding flanges, butt-welding ring plate yakasununguka flanges. , flat welding ring plate yakasununguka flanges, flanged ring plate yakasununguka flanges, flange inovhara.
WCB (carbon simbi), LCB (yakaderera tembiricha kabhoni simbi), LC3 (3.5% nickel simbi), WC5 (1.25% chromium 0.5% molybdenum simbi), WC9 (2.25% chromium), C5 (5% chromium 0.5% molybdenum), C12 (9% chromium uye 1% molybdenum), CA6NM (4 (12% chromium simbi), CA15 (4) (12% chromium), CF8M (316 Stainless simbi), CF8C (347 Stainless simbi), CF8 (304 Stainless simbi ), CF3 (304L) Stainless simbi), CF3M (316L Stainless steel), CN7M (alloy steel), M35-1 (Monel), N7M (Haast Nickel Alloy B), CW6M (Hasta Nickel Alloy C), CY40 (Inconel) Mira.
Maitiro ekugadzira anonyanya kukamurwa kuita mana marudzi: kuforoma, kukanda, kucheka nekukunguruka.
(1) Kanda flange uye flange yakagadzirwa
Iyo flange yakakandwa ine chimiro chakarurama uye saizi, diki yekugadzirisa vhoriyamu uye yakaderera mutengo, asi ine zvikanganiso zvekukanda (pores, cracks, inclusions);chimiro chemukati chekukanda chakashata mukugadzirisa (kana chiri chikamu chekucheka, kuyerera kwakaipa);
Mafurange akagadzirwa kazhinji ane kabhoni yakaderera pane yakakandwa flange uye haisi nyore kuita ngura.Forgings inokwenenzverwa, iine denser chimiro, uye iine zvirinani mechanic zvivakwa pane cast flanges;
Maitiro asina kunaka ekugadzira anokonzeresa hombe kana kusaenzana ekristaro tsanga, kuomesa mitswe, uye mari yekugadzira yakakwira kupfuura yakakandwa flanges.
Forgings inogona kumira yakakwirira shear uye tensile masimba pane castings.
Zvakanakira castings ndezvekuti vanogona kuburitsa maumbirwo akaomarara uye mutengo wakaderera;
Zvakanakira forgings ndezvokuti chimiro chemukati chakafanana, uye hapana zvikanganiso zvinokuvadza senge pores uye inclusions mukukanda;
Kubva pamaitiro ekugadzira, mutsauko uripo pakati pe cast flange uye forged flange wakasiyana.Semuenzaniso, centrifugal flange imhando yekukanda flange.
Centrifugal flanges ndeyeiyo chaiyo yekukanda nzira yekugadzira flanges.Kuenzaniswa neyakajairwa jecha kukanda, chimiro cherudzi urwu rwekukanda chakanyanya kunaka, uye mhando inovandudzwa zvakanyanya.Haisi kutarisana nematambudziko akadai seyakasununguka chimiro, pores, uye trachoma.
Chekutanga pane zvese, isu tinofanirwa kunzwisisa kuti iyo centrifugal flange inogadzirwa sei, iyo nzira uye chigadzirwa checentrifugal casting kugadzira iyo flat welding flange, inoratidzwa mukuti chigadzirwa chinogadziriswa kuburikidza nematanho anotevera:
① Isa yakasarudzwa yakabikwa simbi muchoto chemagetsi chepakati chekunyungudutsa, kuitira kuti tembiricha yesimbi yakanyungudutswa isvike 1600-1700 ℃;
② Preheat simbi mold kusvika 800-900 ℃ kuchengetedza tembiricha isingaperi;
③ Tanga iyo centrifuge, wodira simbi yakanyungudutswa munhanho ① musimbi mold mushure mekupisa munhanho ②;
④ Iko kukanda kunotonhorera ku800-900 ℃ uye kunochengetwa kwemaminetsi 1-10;
⑤ Kutonhoresa nemvura kusvika padyo netembiricha yakajairwa, bvisa uye ubvise kukanda.
