Boiler Pipe

Boiler Pipeipombi yesimbi isina musono yakagadzirirwa kunyanya kudziya-uye{1}}kudzvanya sevhisi. Boiler pombi inozivikanwawo seChrome-Moly Pipe (Chromium{4}}Molybdenum Alloy Steel Pipe) inowanzoitika.Cr–Mo low-alloy steelyakagadzirirwa-kupisa/yakakwirira-kudzvanyirirwa sevhisi, uko kusimba kwemhepo uye oxidation resistance inodzora kutenderera kwehupenyu. Mukuita, kutenga "boiler pombi" kunoitwa giredhi-inofambiswa (somuenzaniso, P11/P22/P91), nokuti dhizaini alloy + magadzirirwo ekupisa anotemesa{10}}kushanda kwenguva refu pasi pesimba rinopisa uye rinopisa mvura.

Nekuwedzera chromium (Cr) uye molybdenum (Mo) kusimbi, pombi idzi dzinopa simba rakatanhamara repamusoro-tembiricha, kusakwira, oxidation resistance, uye corrosion resistance. Iwo anoshandiswa zvakanyanya mumidziyo yakakosha inobata chiutsi, mvura inopisa, uye corrosive media, senge magetsi ekudyara boilers, petrochemical heaters, kupisa kupisa, uye kumanikidza mapaipi.
Nemakore epasi rose ruzivo rwekupa purojekiti, Octal Pipe inogadzira uye kuendesa boiler mapaipi mukuteerana kwakazara neASTM, ASME, DIN, EN zviyero. Magiredhi anovharira P1–P92 neP122, tichiona mhinduro dzezvese kubva kumaboiler emazuva ese kusvika kune epamusoro-supercritical units.

• ASTM A335 / ASME SA335: Ferritic alloy simbi isina musono pombi dzepamusoro-tembiricha sevhisi
• ASTM A213 / ASME SA213: Seamless alloy simbi mapaipi e boiler uye superheater application
• DIN EN 10216-2: Seamless simbi machubhu nekuda kwekumanikidza

Common Giredhi & Zvishandiso:

• P1, P2– Yakaderera-magiredhi alloy yepakati tembiricha sevhisi
• P11, P12, P22-Inoshandiswa zvakanyanya musimba & petrochemical yakakwirira-tembiricha yehutsi
• P5, P9, P21- Yakakwidziridzwa corrosion kuramba kune inoda makemikari nharaunda
• P91, P92, P122-Epamusoro-magiredhi ekushanda kweakanyanya-mabhaira epamusoro ane hupenyu hurefu uye simba repamusoro

Boiler Pipe Matsanangudzo (Saizi, Chirongwa, Migumo & Miedzo)

Mumagwaro eprojekiti,"boiler chubhu simbi giredhi"kazhinji zvinorevaASTM A213tube mamakisi, apo"boiler pipe"kazhinji mareferensiASTM A335pombi mamakisi. A213 inovharisa isina musono bhaira/superheater/heat-machubhu ekuchinjanisa, uye A335 inovhara isina musono ferritic alloy-pombi yesimbi yemhando yepamusoro-sevhisi yetembiricha-ino enderana nemhuri, asi inotsanangurwa zvakasiyana mumaBOM nemapasuru ekuongorora.

Kuti udzivise kuvhiringidzika kwegiredhi pakutenga uye kuburitswa kwezvinhu, shandisa iyi inoshanda mitemo:

Mutemo 1 - Gadzirisa zita regiredhi kurudzi rwechinhu:nyoraT-magiredhiyeA213 chubhu zvinhu uyeP-magiredhiyeA335 pombi zvinhu. Izvi zvinodzivirira "chaiyo zvinhu, zvisirizvo chitupa" kurambwa panguva yeEPC ongororo.

Mutemo 2 - Shandisa machinjiro-mareferensi chete segwara, kwete zvinotsiva:mapurojekiti anowanzo kuonaP11 ↔ T11uyeP22 ↔ T22semhuri imwechete sevhisi (pombi vs chubhu zita), asi iyo PO inofanirwa kuramba ichidaidzira iyo chaiyo chiyero uye chigadzirwa fomu.

Mutemo 3 - Usasanganisa seamless chubhu vs seamless pombi zvinodiwa:A213 chubhu zvinhu zvinowanzosungirirwa kumitemo yekugadzira heater/boiler coil uye kusimba kwepamusoro/ID zvinodiwa, nepo A335 pombi zvinhu zvinowanzo tarisa kumanikidziro muganhu uye kutevedzera pombi kodhi.

Mutemo 4 - Sarudzo yegiredhi inenge yakareba-yenguva yakareba-simba retembiricha:akakwira-magiredhi akadaiP91/P92dzinowanzotaurwa apo magadzirirwo acho anoda zvirinani simba renguva refu-pakukwirisa tembiricha, kwete chete "goho repamusoro." Simbisa iyo chaiyo giredhi uye kupisa mamiriro ekurapa anodiwa nekodhi/spec.

Mutemo 5 - Taura pasuru yekuongorora/kupisa, kwete giredhi chete:yeboiler pombi zvinhu mapakeji, vatengi vanowanzoda kujekeswa pamamiriro ekurapa kupisauyeNDT chikamu(pachirongwa cheITP) nekuti izvi zvinokonzeresa kugamuchirwa mumhando yepamusoro-sevhisi.

Mutemo 6 - Kana rondedzero yemidziyo ichiti "chubhu," usatsiva ne "pombi" (uye zvichipesana):kunyangwe zvimiro zvichitaridzika zvakafanana, chiyero / chitupa nzira yakasiyana uye inogona kukonzeresa kusawirirana pakugamuchira.

Procurement tip:Pakutumira maRFQ, sanganisira mutsara wechinhu mazwi sezvaanoonekwa murunyorwa rwemidziyo (semuenzaniso, "ASTM A213 T22 boiler chubhu" kana "ASTM A335 P22 boiler pipe"), wobva wawedzera OD×WT, kureba, uye magwaro anodiwa-iyi ndiyo nzira inokurumidza kudzivirira chitupa chisina kuenderana pakuburitswa kwezvinhu.
