Txuj: ASTM A312, ASTM A213, ASTM A269, ASTM A790
Khoom siv: 304, 304l, 316, 316l, 904l, 254smo, 2205, 2507
Cheebtsam: yeeb nkab, flange, luj tshib, reducer, tee
Service: Customized prefabrication yeeb nkab spools
A prefabricated yeeb nkab spoolyog qhov koj tau txais thaum lub rooj cob qhia tsim ib ntu ntawm koj cov txheej txheem piping - yeeb nkab, fittings, flanges, kev txhawb nqa, tag nrho cov welded, tshuaj xyuas, hydrotested, thiab cim - ua ntej nws xa tuaj rau koj qhov chaw. Cov neeg ua haujlwm hauv qhov chaw ua cov khi- hauv welds. Txhua yam nyob rau hauv nruab nrab tshwm sim nyob rau hauv ib tug tswj lub khw.
Yog vim li cas EPC cov neeg cog lus txuas ntxiv mus rau prefab yog qhov yooj yim: khw welds khiav ntawm 95–98% ua ntej- dhau kev lees paub, thaum cov welds khiav ntawm 85-95% nyob ntawm huab cua thiab kev nkag. Rau 1,000-weld project, qhov sib txawv ntawm 10-13% txhais tau tias 100-130 tsawg dua kho welds - thiab tus nqi sib txawv ntawm kev rov ua dua hauv av piv rau kev rov ua dua hauv lub khw tswj yog kwv yees li 3 ×.

Vuam Parameter Matrix - Tus lej uas mus hauv WPS
Rau txhua pawg khoom siv, cov txheej txheem vuam yuav tsum nyob hauv ib lub qhov rais tshwj xeeb. Ib qho WPS zoo rau kev ua haujlwm prefab qhia txog cov hlau muab tub lim, cov khoom siv hluav taws xob ntau, qhov ntsuas kub sib txawv, cov roj thaiv kev tiv thaiv, thiab PWHT qhov yuav tsum tau ua (lossis txwv). Cov matrix hauv qab no yog cov txheej txheem tsim nyog feem ntau ua raws; koj qhov project WPS tuaj yeem nruj lossis xoob cov no raws li ASME Tshooj IX kev tsim nyog.
| Pawg Khoom | Filler Metal (AWS A5.14) | Thaum tshav kub kub input (kJ / mm) | Interpass Temp Max (degree) | Shielding / Backing | Yuav tsum muaj PWHT? |

Cov cai tseem ceeb ntawm no matrix:
Muab cov muab tub lim rau lub hauv paus hlau chemistry.Siv C276 muab tub lim rau C22 lub hauv paus hlau thiab koj poob qhov HAZ corrosion kom zoo dua koj them rau. Siv ER2209 ntawm 316L thiab koj tsim ib lub xovtooj ntawm corrosion ntawm lub vuam.
Duplex thiab super duplex yeej tsis tau txais PWHT.Yog tias tus neeg tsim khoom thov PWHT rau 2205 lossis 2507, nres qhov kev txiav txim. PWHT nyob rau hauv 600-950℃ntau precipitates sigma theem thiab rhuav tshem cov theem sib npaug.
Thaum tshav kub kub input muaj ob qho tib si qis thiab sab sauv.Tsawg dhau ntawm duplex muab siab ferrite + nitrides (txias cracking txaus ntshai); siab dhau lawm muab sigma + chi theem (tsis muaj corrosion kuj).
Dimensional Tolerances - Tus lej uas txiav txim siab seb koj tus Spool haum rau ntawm qhov chaw
Ib tug spool uas yog 5 hli ntev dhau los lossis 2℃tawm kev sib hloov yuav tsis nruab. Tus neeg tsim khoom txoj haujlwm yog tuav cov qhov ntev no ua ntej xa khoom xa tuaj; koj tus kws tshuaj xyuas txoj haujlwm yog los txheeb xyuas lawv ua ntej txais. Cov no yog cov kam rau ua feem ntau cov haujlwm qhia txog ASME B31.3 §328.
| Hom kam rau ua | Kev txwv ib txwm (ASME B31.3) | Vim Li Cas Nws Tseem Ceeb |
|---|---|---|
| Nruab nrab - mus rau - nruab nrab ntev | ± 3 hli | Ntev spool mismatch=teb rework |
| Ntsej muag - mus rau - lub ntsej muag ntev | ± 3 hli | Flange-rau- haum tsis sib haum |
| Center-rau-ntsej muag | ± 3 hli | Ceg qhov hluav taws xob qhov chaw |
| Angular / flange tig | ± 0.5 degree | Bolt -qhov misalignment → gasket tsis ua haujlwm |
| Flange ntsej muag parallelism (qhov sib txawv) | Tsawg dua los yog sib npaug li 0.5 mm thoob lub ntsej muag | Gasket sealing |
| Internal misalignment ntawm weld (hi-lo) | Tsawg dua lossis sib npaug li 1.6 hli rau NPS Tsawg dua lossis sib npaug rau 24 | Weld quality / stress concentration |
| Ceg qhov hluav taws xob qhov chaw | ± 3 hli | Reinforcement ncoo haum -up |
| Ovality | Tsawg dua lossis sib npaug li 1% ntawm OD (tus qauv) | Flange haum-up, gaskets |
Txhua yam uas tsis yog cov kev txwv no yog rov ua haujlwm dua. Ib tug zoo fabricator xyuas qhov ntev tom qab haum-nce THIAB tom qab vuam (weld shrinkage tuaj yeem rub qhov ntev ntawm qhov ntev ntawm 1-2 hli).
Qhov ntau thiab tsawg, daim ntawv thiab kev xaiv xaiv
Peb prefabricate spools los ntawm NPS 1/2 "mus txog NPS 36", nyob rau hauv ib zaug -spool assemblies txog li 12 m ntev thiab 8 tonnes. Cov rooj sib txoos loj dua tau muab faib ua cov qauv thauj mus los thiab koom nrog rau ntawm qhov chaw.
| Kev teeb tsa | Hom kev siv | Sau ntawv |
|---|---|---|
| Tib -spool nrog flanges ob kawg | Khi- nyob nruab nrab ntawm ob lub ntsiab lus ruaj khov | Feem ntau; yooj yim shipping |
| Multi-spool los ua ke (header + ceg) | Compressor chaw nres tsheb, manifold piping | hnyav dua; tej zaum yuav xav tau kev xa khoom xa tuaj |

Kev npaj kawg yog feem ntau ASME B16.25 bevels (37.5℃tus qauv, 22.5℃rau nyias phab ntsa) rau pob tw -welded pob qij txha; Plain xaus los yog flanges rau flanged pob qij txha; threaded los yog qhov (socket) -welded xaus rau me me - tho kev sib txuas.
Qhov ntau thiab tsawg thiab cov qauv rau feem ntau -Cov khoom xaj
Rau cov alloys peb prefabricate feem ntau (316L, 2205, C276, 625), cov qauv configuration yog:
| Khoom siv | Feem ntau NPS Range | Lub Sijhawm Feem Ntau | Feem ntau Fittings | Filler Hlau |
|---|---|---|---|---|
| 316 / L stainless hlau | NPS 2"-12" | SWB 10S, 40S | B16.9 buttweld (ntev vojvoog luj tshib, sib npaug tees, concentric reducers) | Qauv: ER316L |
| 2205 ua 2 | NPE 2"-8" | SWB 40S, 80S | B16.9 ua | ER2209 (Ni dhau- sib npaug rau theem sib npaug) |

Vim li cas Prefab Vuam Zoo Beats Field Vuam Zoo
Cov lej qhia zaj dab neeg:
| Metric | Field Vuam | Khw Prefab |
|---|---|---|
| Ua ntej - dhau UT/RT txais | 85–95% | 95–98% |
| Welder productivity | 2-3 welds / txiv neej-hnub | 6-8 welds / txiv neej-hnub (lub khw muag khoom + jig) |
| Huab cua qeeb | Los nag / cua / txias tag nrho nres ntau lawm | Sab hauv khw, tsis muaj huab cua cuam tshuam |
| Kev txwv qhov chaw nkag | Scaffolding, confined qhov chaw, ua haujlwm siab | Hauv av -level positioners |
| NDE lub sijhawm teeb tsa | Qhov tseem ceeb (cov neeg ua haujlwm txawb ntawm qhov chaw) | Hauv -tsev RT/UT, tam sim ntawd |
| Rework nqi rau ib qho weld | 2–3 × qub (txiav tawm, re-weld, re- tshuaj xyuas ntawm qhov chaw) | 1.5 × qub (hauv -kho rework yog sai dua) |
Rau 1,000-weld project, qhov sib txawv ntawm 95% thiab 98% ua ntej-kev lees txais yog 30 rework welds txuag. Ntawm 500–700perreworkonfield, 500–700perreworkonfield, 5,000 ib rework hauv khw (qis dua vim tsis muaj kev koom tes), cov nyiaj khaws cia yog kwv yees li $ 30,000 hauv kev rov ua haujlwm ncaj qha - thiab qhov ntawd yog ua ntej suav cov sijhawm rov qab los thiab kev pheej hmoo zoo.
