Qhov no yuav tsum yog cov ntaub ntawv siv los ntawm koj daim ntawv xaj xaj thiab kuaj xyuas koj daim ntawv pov thawj zeb xeem - tsis yog SS400 phaj / bar chemistry rooj, uas tus neeg muag khoom yuav qhia koj yam tsis tau qhia meej tias nws siv rau cov khoom siv raw es tsis yog daim ntawv xeem cov yeeb nkab tiav.
Vim li cas qhov txawv txav no tseem ceeb rau cov neeg yuav khoom
Cov ntaub ntawv raug.Yog tias koj qhov project specification lossis cov ntaub ntawv ntshuam xav tau "JIS G3444 STK400," daim ntawv pov thawj zeb xeem uas tsuas yog siv "JIS G3101 SS400" tej zaum yuav ua tsis tiav los yog tej zaum yuav nug cov lus nug los ntawm kev lis kev cai, tus kws kuaj xyuas, lossis koj tus neeg siv khoom kawg - txawm tias cov yeeb nkab nws tus kheej yog qhov tsim nyog.
Supplier due diligence.Tus neeg muag khoom uas yog qhov sib txawv ntawm cov qauv khoom thiab cov qauv yeeb nkab, thiab tuaj yeem muab cov ntaub ntawv tawm tsam qhov tseeb, feem ntau yog qhov ua kom zoo dua qub dua li tus neeg siv "SS400" xoob xoob raws li kev ntes -tag nrho cov lus lag luam.
Sib piv cov lus kom raug.Thaum sib piv cov quotes los ntawm cov mills sib txawv, paub meej tias txhua tus yog quoting tawm tsam tib lub hauv paus txheej txheem yeeb nkab (G3444 vs. G3452 vs. G3454) - txij li cov kev xeem yuav tsum tau thiab siab haum sib txawv ntawm lawv txawm tias lub hauv paus steel chemistry yuav zoo ib yam ntawm daim ntawv.
Qib sib npaug hauv Lwm Cov Txheej Txheem
Cov neeg yuav khoom hloov ntawm cov qauv (ntau zaus thaum qhov project spec tso cai "los yog sib npaug") feem ntau piv STK400 / SS400 chemistry rau:
| Txuj | Qib | Kwv yees li hauv paus |
|---|---|---|
| GB / T 700 (Tuam Tshoj) | Q235B | Sib piv yield / tensile ntau yam; lees paub qhov cuam tshuam thiab toughness yuav tsum nyias nyias |
| ASTM A36 / A53 Gr.B | A36 (khoom siv) / A53 Gr.B (pipe) | Kev sib piv dav dav; chemistry txwv txawv |
| TS EN 10025-2 | S235 JR | Piv rau chav kawm muaj zog; sib txawv carbon thiab tej yam yuav tsum tau |
Kho cov no raws li qhov pib ntawm kev sib tham nrog koj tus engineer, tsis yog kev hloov pauv tsis siv neeg - qib "sib npaug" tsis tshua zoo ib yam nyob rau txhua qhov kev xeem ntsuas, thiab ib qho kev qhia tshwj xeeb uas teev cov qauv tshwj xeeb feem ntau yuav tsum ua raws nraim tshwj tsis yog tias koj tus neeg tau txais kev pom zoo hloov pauv hauv kev sau ntawv.
FAQ
Q: Puas yog JIS G3101 SS400 yeeb nkab tib yam khoom raws li JIS G3444 STK400 yeeb nkab?
A: Tsis yog raws nraim - G3101 txhais cov khoom siv (phaj, bar, seem txheej txheem) chemistry thiab lub zog yuav tsum tau, thaum G3444 yog cov khoom siv yeeb nkab / raj tiag tiag, nrog qib STK400 raws li nws sib npaug rau SS400-qib chemistry. Hauv kev xyaum, "SS400 yeeb nkab" feem ntau yog luv luv rau STK400 raj, tab sis cov ntaub ntawv yuav tsum siv tus qauv raug rau koj qhov project.
Q: Tus neeg muag khoom puas tuaj yeem muag cov yeeb nkab raws li "SS400" yog tias nws tau sim rau STK400?
A: Yog, thiab qhov no yog ib qho kev lag luam luv luv - tab sis rau cov haujlwm uas xav tau cov ntaub ntawv raug cai (kev lis kev cai clearance, thib peb- kev soj ntsuam tog, engineering kos npe- tawm), nug tus neeg muag khoom kom paub meej thiab lees paub tawm tsam cov qauv yeeb nkab tshwj xeeb (JIS G3444, G3452, lossis G3450) es tsis yog kev cia siab rau daim ntawv lo "SS4.
Q: Dab tsi yog qhov txawv ntawm SGP (G3452) thiab STK400 (G3444) yeeb nkab yog tias ob leeg siv cov khoom siv hlau zoo sib xws?
A: SGP nyob rau hauv G3452 yog npaj rau qhov zoo tib yam, qis - cov kav dej siab (dej, huab cua, roj ntawm qhov siab me me), thaum STK400 nyob rau hauv G3444 yog npaj rau kev siv cov qauv thiab cov khoom siv uas thauj khoom - bearing kev ua tau zoo, tsis muaj kev txwv siab, yog qhov tseem ceeb. Qhov kawg - siv daim ntawv thov yuav tsum txiav txim siab seb tus qauv twg yog qhov tseeb, tsis yog steel chemistry xwb.
Q: Puas yog STK400 haum rau cov kav dej siab?
A: Feem ntau tsis muaj - cov ntawv thov cov kav dej siab yuav tsum tau teev tseg rau JIS G3454 (STPG qib), uas suav nrog cov siab - cov kev ntsuas tshwj xeeb uas tsis suav nrog hauv G3444. Siv STK400 structural raj rau daim ntawv thov siab yam tsis tau lees tias nws ua tau raws li tus qauv siv siab yog qhov kev pheej hmoo tshwj xeeb.
