Ib qho kev thov rau cov lus hais tias tsuas yog "316L luj tshib, 90 degrees" tawm ntawm cov neeg xa khoom los ua qhov kev xav. Ib qho lus hais tuaj yeem suav nrog cov phab ntsa sib txawv, kev tsim khoom lossis kev tshuaj xyuas pob los ntawm lwm qhov. Cov nqi zoo sib xws, tab sis cov khoom yuav tsis yog.
Yuav kom tau txais cov lus hais muaj txiaj ntsig rau316L pob tw weld luj tshib, qhia cov khoom siv tus qauv thiab qib, nominal loj, phab ntsa thickness, lub kaum sab xis, vojvoog, kev tsim kho, kev npaj kawg, cov ntaub ntawv tshuaj xyuas thiab kom muaj nuj nqis. Cov ntawv txheeb xyuas hauv qab no pab pawg yuav khoom tig ib qho kev pom zoo piping specification rau hauv RFQ ntshiab.
1. Pib nrog Daim Ntawv Pom Zoo Piping Specification
Siv qhov project kab chav kawm, cov khoom specification thiab kos duab kho raws li qhov pib. Tus tsim qauv yuav tsum tau txiav txim siab seb 316L puas haum rau cov kev pabcuam thiab cov khoom siv qhov ntev yuav tsum tau ua. Tus neeg muag khoom hais lus yuav tsum lees paub cov kev xav tau, tsis yog hloov cov kev xaiv engineering.
Txuas cov nplooj ntawv qhia tshwj xeeb thiab txheeb xyuas cov qauv siv tau. Yog tias cov ntaub ntawv tsis sib haum, daws qhov tsis sib haum xeeb ua ntej thov cov lus hais ruaj khov. Rau kev hloov ua haujlwm, ib daim duab tuaj yeem pab piav qhia txog kev teeb tsa, tab sis nws yuav tsum nrog cov ntawv txheeb xyuas qhov ntev thiab cov ntsiab lus qhia.
2. Qhia cov qib khoom thiab qib tsim khoom
"316L stainless hlau" txheeb xyuas qib alloy, tab sis nws tsis yog qhov ua tiav haum. Rau wrought austenitic stainless hlau siab-piping fittings,ASTM A403/A403Mhais txog cov khoom siv thiab kev tsim khoom. Qhov twg qhov project qhia tus qauv no, qhia cov qib uas yuav tsum tau muaj, xws li WP316L, thiab cov chav kawm haum haum.
Raws li A403, WP cov chav kawm xaiv qhov txawv ntawm seamless los yog welded kev tsim kho thiab cov kev xeem uas tsis muaj kev cuam tshuam. Nug tus neeg muag khoom kom txheeb xyuas cov chav kawm kom meej. Tsis txhob kho cov welded lwm qhov sib npaug tsuas yog vim nws cov khoom sib tw; tau txais kev pom zoo rau txhua qhov kev tawm mus los ntawm kev yuav khoom specification.
3. Qhia qhov loj thiab phab ntsa Thickness ua ke
Muab cov yeeb nkab nominal loj thiab lub sij hawm yuav tsum tau los yog nominal phab ntsa thickness, nrog rau units. Qhov loj me nominal yog ib qho kev xaiv, tsis yog tag nrho cov ntsuas qhov ntev. Paub meej tias lub luj tshib xaus phim cov yeeb nkab mating qhov ntev xav tau los ntawm qhov project.
Tuav daim ntawv teev npe tag nrho: SCH 40S yuav tsum tsis txhob ua ntsiag to los ua SCH 40. ASME'sstainless hlau yeeb nkab dimension qhiapiav qhia tias qee lub sijhawm nrog cov lus "S" txawv ntawm lawv cov B36.10 cov neeg sib tw ntawm qhov ntau thiab tsawg. Tshawb xyuas lub rooj qhov loj me es tsis xav tias kev sib hloov pauv tau.
Tus lej teem sijhawm tsis yog, los ntawm nws tus kheej, qhov ntsuas siab rau kev ua tiav. Ib yam li ntawd, chav kawm siab flange ib leeg tsis qhia txog lub luj tshib phab ntsa thickness. Nqa cov kev pom zoo qhov yuav tsum tau ua rau hauv txhua kab lus.
4. Paub meej tias lub kaum sab xis, Radius thiab Vuam xaus
Qhia ob lub kaum sab xis thiab lub vojvoog, piv txwv li "90-degree long-radius (LR) luj tshib." Qhov twgASME B16.9siv, txheeb xyuas nws raws li tus qauv haum. Nws muaj xws li qhov ntev, kam rau ua, kev ntsuam xyuas, kuaj thiab cim; nws tsis hloov cov khoom specification.
Yog tias qhov chaw txwv tsis pub, txuas ib daim duab uas qhia qhov chaw uas yuav tsum tau ua - mus rau - qhov kawg qhov ntev thiab qhov chaw sib txuas. Nug tus neeg muag khoom kom chij ib qho luv luv - lub luj tshib, lub kaum sab xis sib txawv lossis kev cai geometry raws li qhov sib txawv. Tsis txhob cia siab rau daim duab catalog los tsim kom haum.
Kuj tseem hais txog qhov yuav tsum tau vuam -kev npaj kawg.ASME B16.25chaw nyob buttwelding-kawg npaj, suav nrog bevels thiab sab hauv lossis sab nraud shaping. Txhua qhov project-kev hloov pauv tshwj xeeb lossis qhov kawg yuav tsum tau muab tso rau ntawm daim duab pom zoo.
5. Txhais kev soj ntsuam, traceability thiab xa tuaj
Cais cov kev cai uas twb muaj nyob rau hauv cov qauv teev tseg los ntawm cov kev xav tau ntawm qhov project ntxiv. Nug tus neeg muag khoom kom paub meej tias cov ntaub ntawv muaj nyob hauv tus nqi thiab txheeb xyuas cov nqi tshuaj xyuas ntxiv. Qhov no ua rau cov lus sib piv tau yooj yim dua thiab zam tsis pom cov ntaub ntawv ploj thaum cov khoom xa tuaj txog.
- Cov ntaub ntawv pov thawj:qhia cov ntaub ntawv soj ntsuam uas xav tau thiab cov ntaub ntawv xav tau los txuas rau cov khoom siv fittings.
- Traceability:qhia tias qhov kub los yog ntau npaum li cas yuav tsum sib xws nrog cov cim, cov npe ntim khoom thiab cov ntaub ntawv khaws tseg.
- Kev tshuaj xyuas:txheeb xyuas ib qho kev xeem ntxiv, kev lees paub, kev tshaj tawm lossis thib peb -kev ua tim khawv rau qhov project.
- Cov xwm txheej thiab ntim khoom:paub meej tias qhov xwm txheej saum npoo av, kev tiv thaiv vuam kawg thiab kev txheeb xyuas cov khoom ntim.
Lub tuam txhab daim ntawv pov thawj tsis yog hloov pauv rau cov ntaub ntawv khoom lag luam uas xav tau los ntawm kev yuav khoom. Tshawb xyuas qhov cuam tshuam thiab cov kev xav tau ntawm qhov project es tsis txhob tso siab rau cov lus qhia dav dav uas tus neeg muag khoom tau "tso ntawv pov thawj."
6. Siv daim ntawv txheeb xyuas RFQ sib npaug
Cov ntawv teev npe hauv qab no yog cov qauv kev yuav khoom, tsis yog ib qho kev xaiv rau ib qho kev ua haujlwm tshwj xeeb. Ua kom tiav nws los ntawm cov ntaub ntawv pom zoo rau qhov project thiab khaws txhua qhov loj lossis sijhawm teem rau ntawm ib kab.
| RFQ khoom | Cov ntaub ntawv suav nrog |
|---|---|
| Khoom | Lub luj tshib weld; kaum sab xis; LR lossis lwm lub vojvoog uas teev tseg |
| Khoom siv | Khoom txheem, tsab, qib thiab haum chav kawm |
| Qhov ntev | Nominal loj, tag nrho lub sij hawm tsim los yog phab ntsa thickness, thiab units |
| Kev tsim kho thiab xaus | Pom zoo txoj kev tsim khoom, haum tus qauv thiab vuam- cov ntsiab lus kawg |
| Kev tshuaj xyuas | Cov ntaub ntawv xav tau, traceability thiab kev kuaj ntxiv |
| Cov ntsiab lus lag luam | Quantity los ntawm kab khoom, qhov chaw xa khoom, hnub xav tau thiab nqe lus hais |
| Cov ntawv txuas | Daim duab kos duab, kho dua tshiab thiab cov nplooj ntawv tshwj xeeb |
Thov ib kab -los ntawm - kab lus teb thiab ib daim ntawv teev cov kev sib txawv. Yog tias muaj lwm txoj hauv kev, nug rau lawv raws li cov kev xaiv sib txawv nrog lawv cov kev sib txawv thiab cov nqi tau hais meej meej.
7. Sib piv qhov kev ua tiav ua ntej xaj
Tshawb xyuas kev ua raws cai ua ntej, tom qab ntawd sib piv cov nqe lus lag luam. Xyuas seb tus nqi hais puas suav nrog tib cov ntaub ntawv, tshuaj xyuas, ntim thiab xa khoom. Qhia meej seb lub sij hawm ua thawj coj tau hais los pib ntawm qhov kev txiav txim tso, kos duab pom zoo lossis lwm qhov tseem ceeb tau pom zoo.
Txhim kho cov lus nug qhib hauv kev sau ntawv thiab nqa cov kev xav tau lees paub rau hauv daim ntawv xaj yuav khoom. Khaws qhov kev pom zoo kos duab kho dua tshiab thiab cov lus teb ntawm tus neeg muag khoom ua ke kom tau txais cov neeg soj ntsuam tuaj yeem tshawb xyuas cov khoom xa tuaj tawm tsam tib qhov kev pom zoo.
Rau cov khoom siv thaum npaj koj qhov kev nug, tshuaj xyuas Jiede Pipeline's90-degree long-radius luj tshib. Xa cov qib xav tau, qhov loj me, phab ntsa thickness, kom muaj nuj nqis thiab cov ntaub ntawv xav tau nrog koj RFQ, thiab nug tus neeg muag khoom kom paub meej tias qhov kev teeb tsa tiag tiag muaj.
