Lub npe "DN 17175" yog kev sib xyaw ua ke ntawm ob txoj kev sib cais uas txhais cov yeeb nkab qhov ntev thiab cov khoom siv.
Qauv: DN150: Qhov no yogTxoj kab uas hla Nominal(DN) metric npe. Nws qhia txog cov yeeb nkab uas kwv yees li hauv kab hauv millimeters. DN 150 yeeb nkab yog kwv yees li 6-nti NPS (Nominal Pipe Size) yeeb nkab.
PAB 175: Qhov no yogSiab Nominal(PN) ntsuam xyuas. Nws qhia tau hais tias qhov siab tshaj plaws tsim cov yeeb nkab tuaj yeem tuav hauv bar ntawm 20 degree.PN 175 yog qhov siab heev - kev ntsuas siab, sib npaug rau 175 bar (~ 2550 psi lossis ~ 17.5 MPa).
Thaum ua ke,TIAB SA 17175hais txog cov pa roj carbon steel yeeb nkab nrog lub nominal txoj kab uas hla ntawm 150mm (6 ntiv tes) thiab qhov ntsuas siab ntawm 175 bar.
Ntsiab Specifications thiab Standards
Cov yeeb nkab no feem ntau yog tsim los rau cov qauv thoob ntiaj teb tshwj xeeb uas txhais tau tias nws qhov ntev, qhov ntev, thiab cov khoom siv. Cov qauv zoo tshaj plaws rau cov kav dej siab - siab yog:
EN 10216 / EN 10217: Cov no yog cov qauv European rau seamless thiab welded steel raj rau lub hom phiaj siab.
ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / ASTM A106 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106 / A53 / ASTM A106) thiab ASTM A106 / A53: Cov no yog cov qauv American rau seamless thiab welded carbon steel yeeb nkab. Rau PN 175, seamless (ASTM A106) version yog yuav luag txhua zaus siv.
ASME B36.10M: Cov txheej txheem no txhais cov qhov ntev (sab nraud txoj kab uas hla, phab ntsa thickness) rau cov yeeb nkab loj.
Dimensions rau DN 150 (NPS 6) yeeb nkab
Rau DN 150 yeeb nkab, tus qauv sab nraud txoj kab uas hla (OD) yog168.3mm 3.
Phab ntsa thickness rau PN 175 ntsuam xyuas yuav raug cais raws li ib qhoNtxiv Strong (XS) los yog Ob Chav Ntxiv Zog (XXS)teem caij.
Hom Phab Ntsa Thickness rau PN175:Koj yuav tau saib ntawm lub sijhawmXXScev.
OD:168.3mm 3
Phab ntsa Thickness (kwv yees):18.26 hli (0.719 nti)
Teem caij:160 (Metric) / XXS (Imperial)
Sab hauv Diameter (ID):OD - (2 x Phab Ntsa Thickness)=168.3 - (2 x 18.26) ≈ 131.8 mm
Lus Cim Tseem Ceeb:Cov phab ntsa tuab yuav tsum tau lees paub nrog cov chaw tsim khoom cov ntaub ntawv los yog cov khoom siv raws li tus qauv (xws li EN 10216-2 rau seamless kav), raws li PN kev ntsuam xyuas tuaj yeem sib txawv ntawm phab ntsa thicknesses nyob ntawm qib steel.
Khoom siv: Carbon Steel
Cov yeeb nkab yog tsim los ntawm cov hlau, uas yog cov hlau thiab carbon hlau. Rau siab - cov ntawv thov siab, qib tshwj xeeb yog qhov tseem ceeb. Cov qib uas muaj xws li:
P235GH(EN Standard): Ib qho tsis yog - alloy zoo steel rau qhov kub thiab txias.
P265GH(EN Standard): Qib siab dua me ntsis.
ASTM A106 Qib B: Qhov no yog qib feem ntau rau siab -kev pabcuam kub. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 240 MPa thiab tensile zog ntawm 415 MPa.
Daim ntawv thov
Vim nws qhov kev ntsuas siab heev, DN 17175 carbon steel yeeb nkab yog siv rau hauv kev thov kev lag luam, xws li:
Siab -Npaum Chav Kab:Hauv cov chaw tsim hluav taws xob thiab cov txheej txheem kev lag luam.
Roj & Roj Kis:Rau cov kab tseem ceeb thiab cov kab sib sau ua ke nrog lub siab lub taub hau siab.
Hydraulic kab:Hauv cov tshuab ua lag luam loj uas xav tau ultra- lub zog ua kua dej siab.
Txheej Txheem Piping:Hauv tshuaj, petrochemical, thiab chiv cov nroj tsuag uas muaj siab - cov kua siab thauj mus los.
Boiler Tubes:Raws li ib feem ntawm lub siab Circuit Court hauv siab -siab boilers.
Qhov zoo thiab qhov tsis zoo
| Qhov zoo | Qhov tsis zoo |
|---|---|
| Siab zog:Withstands siab sab hauv. | Hnyav heev:Yooj yim rau tuav, thauj, thiab nruab. |
| Durability:Resistant rau mechanical puas. | Tus nqi siab:Cov khoom siv ntau dua, ua rau tus nqi siab dua. |

Cov ntsiab lus
DN 17175 Carbon Steel Yeeb Nkabyog ib qho hnyav -lub luag haujlwm, siab- cov yeeb nkab siab nrog 150mm nominal bore. Nws cov yam ntxwv txhais yog nws cov phab ntsa tuab heev, uas tso cai rau nws ua haujlwm ruaj ntseg hauv cov tshuab nrog kev kub siab txog li 175 bar. Nws yog ib qho tseem ceeb hauv kev tsim hluav taws xob, roj thiab roj, thiab lwm yam kev lag luam hnyav uas muaj kev nyab xeeb thiab kev ntseeg siab nyob rau hauv cov xwm txheej huab cua yog qhov tseem ceeb. Thaum muab cov yeeb nkab no, ib txwm qhia cov qauv khoom tiav (xws li EN 10216-2 P235GH) kom ntseeg tau tias koj tau txais cov khoom raug rau koj daim ntawv thov.
