Cov neeg yuav khoom yuav tsum qhia meej cov pa roj carbon steel yeeb nkab los ntawm kev pib nrog cov kev pabcuam thiab kev tswj xyuas cov ntaub ntawv, tom qab ntawd muab lub npe raws nraim tus qauv, tsab, qib, kev tsim khoom, qhov ntev, kev kam rau siab, kev sim, daim ntawv pov thawj tshuaj xyuas, txheej, kev npaj kawg, kos npe, ntim, thiab kom muaj nuj nqis. ASTM, API, thiab EN cov npe yuav tsum tsis txhob raug kho raws li qhov sib npaug tsis siv neeg yam tsis muaj kev pom zoo engineering.

Kev nug thoob ntiaj teb cov yeeb nkab feem ntau ua tsis tiav vim tias tus neeg yuav khoom xa tsuas yog sab nraud txoj kab uas hla, phab ntsa tuab, thiab qib kwv yees. Qhov ntawd tso cov neeg xa khoom los txhais seb cov yeeb nkab puas yog rau kev pabcuam siab, kab yeeb nkab, kev tsim qauv, kev siv tshuab, lossis lwm lub luag haujlwm. Cov lus hais tau tshwm sim tuaj yeem zoo sib piv tab sis suav nrog cov khoom sib txawv, kev sim, kev zam, thiab cov ntaub ntawv.

Pib Nrog Kev Pabcuam, Tsis Paub Qib

Ua ntej xaiv tus qauv, txhais:

• Thauj nruab nrab lossis kev ua haujlwm.
• Tsim thiab ua haujlwm siab.
• Tsim thiab ua haujlwm kub.
• Sab nraud loads thiab installation txoj kev.

• Welding thiab fabrication txoj kev.
• Kev cai tsim qauv thiab cov neeg siv khoom specification.
• Destination-lub teb chaws cov cai.

Tus neeg yuav khoom lub luag haujlwm engineer yuav tsum txiav txim siab cov khoom siv tshwj xeeb. Tus neeg muag khoom tuaj yeem pab txheeb xyuas cov khoom muaj, tab sis yuav tsum tsis txhob nug kom hloov qhov project tsim lub hauv paus nrog "sib npaug."

Standards Family Decision Table

Project lus	Cov neeg yuav khoom ua	Cov neeg muab khoom teb xav tau
ASTM raws li specification	Qhia qhov tseeb ASTM tus qauv, qib, ib tsab, cov kev xav tau ntxiv, thiab txoj haujlwm code	Cia tib lub callout lossis qhia meej txhua qhov sib txawv
API-raws li pipeline specification	Qhia rau API cov khoom specification, qib lossis qib uas siv tau, kev pabcuam ntxiv, thiab cov kev xeem uas xav tau	Paub meej txog kev tsim khoom, qib khoom, kuaj, cim, thiab cov ntaub ntawv
EN raws li specification	Qhia qhov tseeb EN cov qauv khoom, kev tsim steel, kev xa khoom, qhov ntev, thiab cov ntaub ntawv tshuaj xyuas	Paub meej tias tib lub npe thiab txhua qhov kev txiav txim
Hla kev hloov pauv	Muab txoj cai hloov pauv uas tau pom zoo los yog thov ib qho kev pom zoo	Muab kev sib piv ntawm kev sib piv; tsis txhob sau npe rau qib "sib npaug" yam tsis muaj kev tsim nyog

Cov qauv npog ntau dua li chemistry. Lawv tuaj yeem sib txawv ntawm cov khoom siv kho tshuab, qhov ntev, qhov siab, kev kho cua sov, kev xeem zaus, cov ntaub ntawv tshuaj xyuas, cim, thiab cov txheej txheem tsim khoom.

1. Txhais cov qauv khoom thiab kev tsim khoom

Qhia seb qhov kev xav tau yog rau:

• Seamless yeeb nkab.
• Hluav taws xob tiv taus-welded yeeb nkab.
• Longitudinally los yog kauv welded yeeb nkab.
• Cov qauv puag ncig, square, los yog duab plaub seem.
• Liab qab, galvanized, lined, los yog coated yeeb nkab.

Txoj kev lees txais yuav tsum ua raws li kev cai tswjfwm thiab kev pabcuam. Yog tias muaj ntau tshaj li ib txoj hauv kev tau txais, nug cov neeg muag khoom kom hais tawm ib qho kev sib cais es tsis txhob muab sib xyaw rau hauv ib kab.

Maigaotuo cov Steel Pipes qeb npog cov yeeb nkab puag ncig, lub raj square, lub raj raj, thiab cov khoom tshwj xeeb zoo li lub raj xa khoom. Kev xaiv cov khoom kawg tseem nyob ntawm qhov project callout.

2. Qhia qhov Dimensions nyob rau hauv Ib Qhov Kev Tsis Txaus Siab

RFQ yuav tsum txheeb xyuas:

1. Nominal yeeb nkab loj los yog sab nraud txoj kab uas hla.
2. Phab ntsa thickness los yog teem caij.
3. Length thiab tso cai ntev variation.
4. Xaus tiav.
5. Qhov ntsuas qhov ntsuas.
6. Qhov ntau los ntawm qhov loj me.
7. Chav ntsuas.
8. Yuav tsum kam rau siab tshaj li tus qauv hauv paus.

Tsis txhob sib xyaw NPS, DN, sab nraud txoj kab uas hla, lub sijhawm, thiab millimeters yam tsis muaj daim ntawv qhia meej. Ib tug xov tooj teem sij hawm tsis yog universal phab ntsa thickness hla txhua nominal loj. Yog tias qhov project kos duab tswj, muab nws thiab txheeb xyuas qhov kev kho dua tshiab.

3. Kev xaiv qib sib cais los ntawm kev sib tham "sib npaug".

Thaum tus thawj specification npe ib tus qauv thiab cov khoom lag luam siv lwm tus, tsim ib lub rooj sib piv uas suav nrog:

• Tag nrho lub npe thiab ib tsab.
• Yam khoom thiab tso cai tsim txoj kev.

• Kev tshuaj xyuas-cov ntaub ntawv hom.
• Kos npe thiab traceability.

Ib qho kev xaiv yuav tsum raug xa mus rau kev tshuaj xyuas engineering ua ntej yuav khoom. Cov txiaj ntsig zoo sib xws ib leeg tsis tsim kev sib hloov.

4. Lub Xeev Kev Xeem thiab Cov Ntaub Ntawv Yuav Tsum Tau Kab los ntawm kab

RFQ yuav tsum paub qhov txawv qhov yuav tsum tau ua los ntawm kev xaiv cov kev pabcuam tshuaj xyuas.

Cov ntaub ntawv lossis kev xeem	Yuav hais li cas
Mill daim ntawv pov thawj	Yuav tsum muaj hom ntawv, tus qauv, tus lej xov tooj cua sov, chemistry, cov txiaj ntsig ntawm kev siv tshuab, thiab traceability
Kev kuaj tsis raug	Txoj kev, kev pab them nqi, lub hauv paus txais, thiab tshaj tawm yuav tsum tau ua
Kev ntsuam xyuas hydrostatic	Kev tswj xyuas tshwj xeeb thiab seb cov ntaub ntawv xav tau
Dimensional soj ntsuam	Sampling plan, qhia qhov ntev, thiab kam rau ua
Kev tshuaj xyuas thib peb	Lub koom haum, tim khawv / tuav cov ntsiab lus, muaj peev xwm, thiab tshaj tawm lus
Txheej tshuaj xyuas	Kev npaj nto, thickness, kev xeem hnub so, adhesion, lossis lwm yam yuav tsum tau ua
Kev txheeb xyuas cov khoom zoo	Qhov chaw, sampling, txheej txheem, thiab tshaj tawm yog tias xav tau

Tsis txhob thov txhua qhov kev xeem los ntawm lub neej ntawd. Txhua qhov kev xeem ntxiv hloov pauv nqi, teem caij, thiab tswj cov ntaub ntawv. Qhia tsuas yog qhov project xav tau, tab sis ua kom pom cov kev xav tau ua ntej hais.

5. Txhais Deg, Txheej, Xaus, thiab Fabrication

suav nrog:

• Liab qab, oiled, pleev xim rau, galvanized, los yog project txheej txheej.
