P355N Steel Welded Yeeb Nkab - Normalized Fine-Ntshav Siab Tube rau EN 10217-3
P355N steel welded yeeb nkabyog ib qho zoo, weldable fine-grain siab raj muab rau EN 10217-3, nrog rau qhov tsawg kawg nkaus lub zog ntawm 355 MPa (51,500 psi) rau phab ntsa thickness txog 16 hli thiab tensile ntau ntawm 490–630 MPa (71,100 psi). Nws yog qhov cuam tshuam - kuaj ntawm 0℃thiab siv rau cov hlab ntsha siab, boilers, txheej txheem kav dej thiab cia tso tsheb hlau luam ntawm ambient mus rau nruab nrab kub. Tus lej nkaus xwb uas txiav txim siab koj cov phab ntsa thickness yog qhov tsim tawm - thiab nws nqis nqis raws li phab ntsa tau thicker, yog li cov npe qib ib leeg tsis kho tus nqi.
P355N yog European siab- nkoj steel hauv EN 10027 / EN 10028 tsev neeg. Nyeem lub npe nyob rau hauv peb qhov kev ywj pheej:Pcim lub siab- lub hom phiaj steel,355yog qhov tsawg kawg nkaus tawm lub zog hauv MPa, thiabNtxhais tau hais tias cov hlau raug xa mus li qub nrog chav -kub (0 degree) cuam tshuam kev tsim nyog. Nws tsis yog qib structural thiab nws tsis yog qis -qib kub - cov no yog cov lus sib txawv hauv tib tsev neeg.

FAQ
P355N steel welded yeeb nkab yog dab tsi?
Nws yog welded siab raj ua los ntawm P355N, ib tug normalized weldable nplua -grain steel (khoom siv 1.0562) muab rau EN 10217-3. Yam tsawg kawg nkaus tawm los yog 355 MPa rau phab ntsa thickness mus txog 16 hli thiab tensile ntau yog 490-630 MPa. Nws yog siv rau cov hlab ntsha siab, boilers, piping thiab cia tso tsheb hlau luam ntawm ambient mus rau nruab nrab siab kub.
Puas yog P355N tib yam li S355 (S355 JR / S355J2)?
No. S355 yog cov qauv hlau raws li EN 10025 uas tsis muaj qhov siab - khoom siv ntawv pov thawj thiab tsis muaj kev lav phib xaub rau lub zog ntawm 0℃los ntawm lub neej ntawd. Rau kev pabcuam siab qhov tseeb European qib yog P355N (chaw kub), P355NH (−20℃/ siab), P355NL1 (−40 degree) lossis P355NL2 (−50 degree) hauv qab EN 10217-3 / EN 10028-3.
Qhov txawv ntawm P355N, P355NH thiab P355NL1 / P355NL2 yog dab tsi?
Lawv sib koom tib yam 355 MPa yield tab sis txawv los ntawm guaranteed cuam tshuam qhov kub thiab txias: P355N ntawm 0 degree, P355NH ntawm −20℃(nrog elevated-kub zog), P355NL1 ntawm −40 degree, P355NL2 ntawm −50℃for offshore./arctic service. Kev qhia qhov tsis ncaj ncees lawm txhais tau hais tias qhov kev tsim nyog cuam tshuam tsis zoo rau qhov kev pabcuam kub.
P355N tuaj yeem siv rau qhov kub thiab txias?
P355N yog chav tsev -qib kub, cuam tshuam- tsim nyog ntawm 0℃(40 J longitudinal / 27 J transverse yam tsawg kawg nkaus nruab nrab). Rau sub-zero tsim qhia P355NH (−20 degree), P355NL1 (−40 degree) lossis P355NL2 (−50℃). Siv P355N qis dua 0℃txhais tau hais tias qhov toughness tsis tau lees paub los ntawm tus qauv.
Cov txheej txheem vuam siv li cas rau EN 10217-3 P355N yeeb nkab?
TS EN 10217-3 npog hluav taws xob (HFW / ERW, seam ntev) thiab submerged -arc welded raj (SAWL longitudinal, SAWH helical). HFW haum cov kab me me; SAW ncav cuag qhov loj dua thiab cov phab ntsa hnyav dua. Rau cov kev pabcuam siab qhia meej xeem qeb TC2, uas ua rau weld-seam ultrasonic xeem yuav tsum tau.
Dab tsi yog qhov txawv ntawm EN 10217-3 (welded) thiab EN 10216-3 (seamless)?
Ob leeg txhais tau zoo tib yam - qib siab siab (P355N/NH/NL1/NL2) tab sis los ntawm txoj kev sib txawv: EN 10217-3 yog welded (HFW lossis SAW), EN 10216-3 yog seamless. Lub vuam yog qhov sib txawv ntawm qhov tseem ceeb - welded yeeb nkab yuav tsum tshaj tawm cov txheej txheem vuam thiab TC1 / TC2 weld kuaj; seamless yeeb nkab tsis muaj longitudinal weld. Ib qho tshwj xeeb uas hais tias "EN 10217-3 seamless" yog qhov tsis sib xws.
P355N yeeb nkab nqa tau siab npaum li cas?
Nws nyob ntawm sab nraud txoj kab uas hla, phab ntsa thickness thiab txoj cai tsim qauv. Raws li kev tshuaj ntsuam xyuas ntawm OD 323.9 hli, tsim kev ntxhov siab 0.7 × 355=249 MPa thiab kev sib koom ua haujlwm 1.0: 25 bar xav tau txog 1.6 hli phab ntsa, 50 bar txog 3.3 hli, 100 bar txog 6.8 hli (ua ntej corrosion nyiaj). Phab ntsa kawg yuav tsum yog los ntawm EN 13445 / ASME VIII / PD 5500 siv cov cai tso cai rau kev ntxhov siab.
Daim ntawv pov thawj thiab kev tshuaj xyuas dab tsi tuaj nrog P355N welded yeeb nkab?
Txhua qhov kev txiav txim xa tuaj nrog EN 10204 3.1 daim ntawv pov thawj zeb xeem (kev ntsuas cua sov, ntsuas ntsuas ntsuas, ntsuas cua sov). Hydrostatic/leak test thiab, rau TC2, yuav tsum weld-seam UT per EN 10246 yog ua. Thib peb-kev tshuaj xyuas los ntawm SGS, TÜV, BV lossis zoo sib xws muaj nyob rau ntawm kev thov.
