A516 Qib 70yog hom carbon steel phaj dav siv rau kev siv lub nkoj siab. Nws yog lub npe hu rau nws zoo ua ke ntawm lub zog thiab toughness, uas tso cai rau nws ua kom ntseeg tau nyob rau hauv high pressures thiab fluctuating kub. Cov hlau yog ua tib zoo tswj xyuas kom zoo weldability, ua rau nws yog ib qho kev xaiv rau fabricating loj thiab complex hlab ntsha nyob rau hauv cov roj, roj, thiab tshuaj industries. Nws muaj peev xwm tiv taus cov pob txha tawg, txawm tias qhov kub thiab txias, kuj ua rau nws haum rau qis - qhov kub thiab txias kev pab cuam thiab cia tso tsheb hlau luam. Zuag qhia tag nrho, nws yog cov khoom siv ntau yam thiab muaj kev ntseeg siab uas feem ntau tau teev tseg rau cov cuab yeej tseem ceeb uas yuav tsum tau muaj kev ncaj ncees siab thiab ua haujlwm ntev -.

daim ntawv thov
Cov nkoj siab
A516 Qib 70 yog dav siv rau fabricating siab hlab ntsha nyob rau hauv cov roj, roj, thiab petrochemical industries. Nws yog qhov tsim nyog rau cov hlab ntsha uas khaws cia lossis ua cov kua dej thiab cov pa hauv qab qhov siab thiab qhov kub thiab txias, nrog rau cov reactors, cais, thiab cov txheej txheem cov hlab ntsha.
Boilers thiab Kub Exchangers
Cov qib no feem ntau yog siv rau hauv kev tsim hluav taws xob thiab cov tshuab cua sov hauv tsev. Nws yog siv rau boiler nruas, headers, thiab tshav kub exchanger Cheebtsam uas tsis kam mus rau thermal stress thiab siab kub yog qhov tseem ceeb.
Cia Tank
Nws yog cov khoom siv zoo tshaj plaws rau lub tank loj uas tsim los tuav cov roj av, cov khoom siv roj av, thiab tshuaj lom neeg. Nws feem ntau tau teev tseg rau cov tso tsheb hlau luam ua rau cov qauv kev lag luam, muab cov qauv kev ncaj ncees thiab ua haujlwm rau ib puag ncig loads.
Cov khoom siv Cryogenic
Vim nws zoo heev toughness ntawm qhov kub thiab txias, A516 Qib 70 yog siv nyob rau hauv cryogenic cia thiab ua khoom siv. Nws yog qhov tsim nyog rau LPG, LNG, thiab lwm yam tsawg - daim ntawv thov kub qhov kev tiv thaiv rau cov pob txha tawg yog qhov tseem ceeb.
Industrial Machinery thiab Piping
Cov hlau yog siv nyob rau hauv ntau yam hnyav industrial Cheebtsam xws li compressors, siab piping, thiab txheej txheem khoom. Nws kev sib xyaw ua ke ntawm lub zog thiab weldability ua rau nws zoo tagnrho rau cov tshuab uas xav tau kev ua haujlwm txhim khu kev qha raws li qhov xav tau.

Qhov txawv ntawm A516 qib 60 thiab qib 70 yog dab tsi?
ASTM A516 Qib 70 muaj lub zog siab dua (tensile & yield) dua qib 60, ua rau nws tsim nyog rau kev siv siab dua / kub, thaum Qib 60 muab cov khoom zoo dua rau cov xwm txheej nruab nrab, nrog Qib 70 feem ntau muaj cov ntsiab lus siab dua me ntsis kom ua tiav nws lub zog nce, txawm tias ob qho tib si tseem zoo heev rau boilers thiab siab hlab ntsha.
516 GR 70 sib npaug li cas?
Cov sib npaug sib npaug suav nrog ASME SA516 GR 70, EN 10028 P355GH, thiab BS1501 224-490 A & B, tsim nyog rau kev siv lub nkoj zoo sib xws.
Weldability ntawm A516 Qib 70 yog dab tsi?
A516 Qib 70 muaj qhov zoo tshaj plaws weldability thiab tuaj yeem siv cov txheej txheem xws li SMAW, GMAW, FCAW, thiab SAW. Preheat tej zaum yuav xav tau rau cov phaj tuab lossis hauv huab cua txias kom tiv thaiv hydrogen tawg.
Puas yog A516 Qib 70 xav tau kev kho cua sov?
Nws yog feem ntau nkag rau hauv cov xwm txheej normalized kom ntseeg tau zoo toughness. Kev kho cua sov tom qab vuam (PWHT) tej zaum yuav raug teev raws li cov thickness, cov khoom siv toughness, thiab cov cai tsim qauv.
