Dab tsi tiag txiav txim siab "High Pressure" muaj peev xwm
Kev ntsuas siab tsis yog cov cuab yeej ruaj khov ntawm cov yeeb nkab loj - nws yog qhov tshwm sim ntawm plaub qhov sib txawv ua haujlwm ua ke:
- Sab nraud txoj kab uas hla (OD)- OD me dua siab dua ntawm cov phab ntsa tuab
- Phab ntsa thickness- phab ntsa tuab nce siab, ua raws li Barlow tus qauv: P=(2 × S × t) / D
- Khoom tawm los / tensile zog (SMYS)- siab dua- alloys muaj zog cia cov phab ntsa nyias nyias rau tib lub siab
- Tsim yam khoom / kev nyab xeeb margin- teeb tsa los ntawm txoj cai tswjfwm, uas txawv ntawm chav pabcuam thiab qhov ua rau tsis ua haujlwm
Qhov no txhais tau hais tias tib lub nominal yeeb nkab loj tuaj yeem ntsuas rau qhov sib txawv ntawm qhov sib txawv nyob ntawm phab ntsa tuab thiab cov khoom siv qib - cov neeg yuav khoom yuav tsum nco ntsoov lees paub qhov ntsuas ntsuas qhov ntsuas siab tiag tiag es tsis xav tias qhov loj me ib leeg.
Phab ntsa Thickness / Teem caij siv
Kev siv siab siab feem ntau hu rau lub sijhawm hnyav dua li cov kav dej txheem:
- Teem caij 80 / XS- yam tsawg kawg nkaus rau nruab nrab siab - kev pabcuam siab
- Teem caij 160- siv rau siab dua -siab chav thiab txheej txheem kab
- XXS (ob npaug ntxiv muaj zog)- tshwj tseg rau qhov xav tau tshaj plaws ntawm kev sib xyaw ua haujlwm siab / kub
- Kev cai phab ntsa thickness- rau hydraulic lub tog raj kheej raj thiab tshwj xeeb siab hlab ntsha, phab ntsa thickness feem ntau teev raws li ib tug meej dimension es tsis yog ib tug txheej txheem teem caij, raws li lub honed bore thiab ua hauj lwm siab ntawm lub tog raj kheej
Tej kev siv
- Kev tsim hluav taws xob:boiler superheater / reheater tubing, lub ntsiab chav kab, feedwater piping
- Petrochemical kev lag luam:siab -pressure reactor feed kab, hydroprocessing units, catalytic reforming piping
- Hydraulic systems:cylinder chim raj, hydraulic xovxwm piping, mobile hydraulics
- Cov hlab ntsha siab:lub caj dab nozzles, siab - cov kev kawm siab ntawm lub nkoj plhaub
- Gas compression:compressor discharge piping, siab -siab gas cia manifolds
Mechanical Properties (API 5L X52 Reference)
- Yield zog:Ntau dua lossis sib npaug rau 359 MPa (52,000 psi)
- Tensile zog:Ntau dua lossis sib npaug rau 455 MPa (66,000 psi)
- Elongation:Raws li API 5L formula raws li phab ntsa thickness thiab txoj kab uas hla
- Charpy impact (PSL2):Tsawg kawg nkaus absorbed zog ib API 5L Annex yuav tsum tau, kuaj ntawm qhov ntsuas kub
Cov qib siab dua (X60, X65, X70) tso cai rau cov phab ntsa nyias nyias rau tib qhov kev ntsuas siab, txo cov yeeb nkab hnyav thiab nqi thauj mus los - tab sis yuav tsum tau ua tib zoo soj ntsuam ntawm thaj chaw weldability thiab muaj cov txheej txheem vuam.
Kev Ntsuas & Kev Ntsuas Zoo
Vim tias qhov tshwm sim tsis ua tiav yog qhov hnyav dua nyob rau hauv siab - kev pabcuam siab, kev sim ntsuas feem ntau mus dhau qhov kev kuaj xyuas zeb:
- Kev ntsuam xyuas hydrostaticmus rau ib qho kev ntsuas siab (feem ntau 1.5 × tsim siab) ntawm 100% ntawm kev tsim khoom
- Kev kuaj ultrasonic (UT)rau phab ntsa thickness pov thawj thiab sab hauv qhov tsis xws luag
- Eddy tam sim no xeem (ECT), feem ntau yog rau nyias - phab ntsa tubing qhov twg UT rhiab heev yog txwv
- Kev txheeb xyuas cov khoom zoo (PMI), tshwj xeeb tshaj yog ib qho tseem ceeb rau cov qib alloy (P11/P22/P91) qhov sib tov-ups ntawm zoo sib xws- saib yeeb nkab tuaj yeem ua rau loj hauv - kev pabcuam tsis ua haujlwm
- Charpy V- ntsuas qhov cuam tshuamrau qis- kub los yog siab - yuav tsum muaj toughness
Cov lus nug nquag nug (FAQ)
Q: Dab tsi yog qhov txawv ntawm kev kub siab seamless yeeb nkab thiab txheem hydraulic raj?
A: Ob leeg yuav seamless thiab ob leeg tuav lub siab, tab sis hydraulic lub tog raj kheej raj yog ntxiv tau teev nrog ib tug honed puab bore mus rau ib tug nruj dimension kam rau ua thiab tswj nto roughness (Ra) rau foob thiab piston compatibility. Txheem siab - cov yeeb nkab siab rau cov kav dej (piv txwv li, boiler lossis cov kab txheej txheem) tsis yog honed thiab tsis nqa tib qhov kev xav tau tag nrho - ob qho tib si tsis sib hloov txawm nyob rau tib qhov kev ntsuas siab nominal.
Q: Puas yog kev kuaj PMI tiag tiag, lossis daim ntawv pov thawj zeb puas txaus?
A: Daim ntawv pov thawj zeb sau cov ntaub ntawv uas yuav tsum yog, tab sis Cov Khoom Siv Zoo (PMI) txheeb xyuas qhov tseeb chemistry ntawm cov yeeb nkab tshwj xeeb hauv tes - qhov no tseem ceeb vim tias cov qib alloy xws li P11, P22, thiab P91 tuaj yeem zoo tib yam rau carbon steel lossis ib leeg. PMI raug suav hais tias yog tus qauv coj ua rau cov phiaj xwm tseem ceeb ntawm cov kav dej ua tau zoo vim tias daim ntawv pov thawj -tsuas yog kev txheeb xyuas tau ua rau muaj nqi sib xyaws - nce hauv thaj teb.
Q: Puas yog tib lub yeeb nkab loj tuaj yeem ntsuas rau qhov sib txawv?
A: Yog. Kev ntsuas siab nyob ntawm phab ntsa thickness thiab qib khoom, tsis yog OD ib leeg. Tib lub nominal txheej sab nraud tuaj yeem muab tau rau hauv ntau lub sijhawm (xws li Teem sijhawm 80, 160, XXS), txhua qhov ntsuas rau qhov sib txawv siab tshaj plaws ntawm qhov muab qhov kub thiab txias - ib txwm paub meej tias phab ntsa tuab thiab qib tom qab qhov ntsuas siab, tsis yog cov yeeb nkab loj.
Q: Puas yog kev kub siab tau txhais tau tias kuv xav tau cov hlau alloy es tsis txhob carbon steel?
A: Tsis tas li. carbon hlau (piv txwv li,ASTM A106 1Qib B) tuaj yeem tswj tau qhov siab loj yog tias phab ntsa tuab yog qhov loj me kom raug - hlau alloy yuav tsim nyog thaum ua haujlwmkubnce mus rau qhov chaw uas carbon steel lub zog degrades lub sij hawm (creep) los yog qhov twg qaub / corrosive kev pab cuam yuav tsum tau nws. Kev kub siab ib leeg, ntawm qhov kub nruab nrab, feem ntau daws nrog cov pa roj carbon steel thiab cov phab ntsa tuab txaus.
