simbi isina ngura yakagadzirwa nemakumbo akabatana flange yakasununguka kora sch stub end flange

Flange ine lap-joint inoda zvikamu zviviri zvepombi kumativi ese e flange, stub end uye backing flange yakasununguka. Flange yakasununguka backing inokodzera pamusoro pe dhayamita yekunze ye stub end, iyo yakasungirirwa kumabutt kupombi. Backing flange haina weld kupombi, uye inogona kutenderedzwa, izvo zvinonyanya kubatsira kana zvichidikanwa kutenderedza flanges panguva yekumira.

Uyewo, sezvo flange yekumashure isingabatani ne process fluid, inogona kugadzirwa nezvinhu zvisinganyanyi kukuvadza. Semuenzaniso, kana process yacho ichikuvadza uye ichida kuti pombi ive yesimbi isingatsvedzeri, sezvakaita muASTM A312 TP316L, saka stub end inofanirawo kugadzirwa neSS 316L; zvisinei, flange yekumashure inogona kugadzirwa neASTM A105 yakachipa.

Nzira iyi yekubatanidza haina kusimba seweld neck flange asi iri nani pane screwed, socket weld, uye slip on connections; zvisinei, inodhura kuita izvi, nekuti inoda full-penetration butt weld uye inoda zvikamu zviviri.

Stub End inogara ichishandiswa neLap Joint flange, se backing flange.

Kubatanidza flange uku kunoshandiswa, mukushandiswa kusingadhuri uye kusiri kwakakosha, uye inzira yakachipa yekuputira.
Semuenzaniso, muhurongwa hwemapaipi esimbi isina ngura, flange yesimbi yekabhoni inogona kuiswa, nekuti haibatani nechigadzirwa chiri mupaipi.

MaStub Ends anowanikwa munenge madhayamita ese epombi. Zviyero uye kushivirira kwezvikamu zvinotsanangurwa muASME B.16.9 standard. MaStub Ends (fittings) anodzivirira ngura anotsanangurwa muMSS SP43.

• Rusununguko rwekutenderedza pombi runobatsira kuti maburi emabhaudhi eflange akwire.
• Kusasangana nemvura iri mupombi kunowanzo bvumidza kushandiswa kwesimbi dzekabhoni dzisingadhuri dzine mapaipi anodzivirira ngura.
• Mumasystem anopwanyika kana kuora nekukurumidza, maflange anogona kuchengetwa kuti ashandiswezve.

Zvigadzirwa zvakadzama zvinoratidzwa

1. Chiso
chiso chakati sandara, Radius ndiyo inonyanya kukosha

2. Nehub kana kuti pasina hub

3. Kupedzisa kwechiso
Kupera kweflange kunoyerwa seArithmetical Average Roughness Height (AARH). Kupera kunotsanangurwa nechiyero chinoshandiswa. Semuenzaniso, ANSI B16.5 inotsanangura kupedzisa kwechiso mukati me125AARH-500AARH (3.2Ra kusvika 12.5Ra). Mamwe mafinishe anowanikwa kana uchida, semuenzaniso 1.6 Ra max,1.6/3.2 Ra, 3.2/6.3Ra kana 6.3/12.5Ra. Kureba kwe3.2/6.3Ra ndiko kwakajairika.

Kumaka uye kurongedza

• Rutivi rumwe nerumwe runoshandisa purasitiki kudzivirira pamusoro

• Kune simbi isingasvibi, mapuranga epurasitiki anoiswa mubhokisi replywood. Kuti mapuranga ecarbon flanges akwanise kukura, mapuranga anoiswa mubhokisi replywood. Kana kuti anogona kurongwa kuti agadziriswe.

• Chiratidzo chekutumira chinogona kuitwa kana chakumbirwa

• Zviratidzo pazvigadzirwa zvinogona kuvezwa kana kudhindwa. OEM inogamuchirwa.

Kuongorora

• Kuongororwa kweUT

• Kuongororwa kwePT

• Kuongororwa kweMT

• Kuyedzwa kwehukuru

Tisati tasvika, timu yedu yeQC icharonga bvunzo yeNDT uye kuongororwa kwehukuru hwayo. Inogamuchirawo TPI (kuongororwa kwebato rechitatu).

Maitiro ekugadzira

Zvishandiso zvepombi zvinhu zvakakosha muhurongwa hwemapaipi, zvinoshandiswa pakubatanidza, kudzoreredza, kutsausa, kuchinja saizi, kuvhara kana kudzora kuyerera kwemvura. Zvinoshandiswa zvakanyanya mumabasa akadai sekuvaka, maindasitiri, simba uye mabasa emakanzuru.

Mabasa Akakosha:Inogona kuita mabasa akadai sekubatanidza mapaipi, kushandura nzira yekuyerera kwemvura, kupatsanura nekubatanidza kuyerera kwemvura, kugadzirisa dhayamita yemapaipi, kuvhara mapaipi, kudzora nekugadzirisa.

Mashandisirwo Ekushandisa:

• Kuvaka mvura uye nzira dzekubvisa mvura:Magokora ePVC nePPR tris zvinoshandiswa pakubatanidza mapaipi emvura.
• Mapaipi emaindasitiri:Maflange esimbi isina ngura uye magokora esimbi alloy anoshandiswa kutakura zvinhu zvine makemikari.
• Kutakurwa kwesimba:Zvishandiso zvesimbi zvine simba guru zvinoshandiswa mumapaipi emafuta negesi.
• HVAC (Kudziisa, Kufefetedza, uye Kutonhodza Mhepo):Zvishandiso zvemapaipi emhangura zvinoshandiswa kubatanidza mapaipi emufiriji, uye majoini anochinjika anoshandiswa kuderedza kudedera.
• Kudiridza kwekurima:Zvinobatanidza zvinokurumidza zvinoita kuti zvive nyore kuunganidza nekuputsa masisitimu ekudiridza sprinkler.
