High -} Cov Ntsiab Lus
API spec 5lyog cov ntaub ntawv tshwj xeeb tshaj tawm los ntawm Asmeskas Petroleum Lub Koom Haum (API). Nws txhais cov qauv rau kev tsim khoomKab YeebSiv rau hauv cov roj thiab roj txuas xov hluav taws xob.
Hauv API 5L, muaj ob theem khoom lag luam tshwj xeeb (PSL):
PSL 1Cov qauv tsim nyog. Nov yog cov qib thiab dav dav siv rau kev pabcuam dav dav.
PSL 2: Ntxiv, ntau txoj hlua khi yuav tsum muaj rau tshuaj muaj kuab lom, kev muaj zog, lub zog, thiab kuaj. Siv rau cov ntawv thov tseem ceeb ntxiv (piv txwv li, tawm tsam, Arctic, siab- siab kab).
A Seamless Steel Yeeb Nkabyog tsim los ntawm tho ib lub nplua nuj ntawm cov hlau los tsim lub plhaub khoob tsis muaj welds raws nws qhov ntev. Qhov no ua rau nws inherently muaj zog thiab zoo rau high-} qhov kev siv siab.
Yog li ntawd,API 5L PSL1 Seamless Steel Yeeb Nkabyog weld - dej dawb tsim rau cov qauv API 5L yuav tsum tau, haum rau ntau yam ntawm onshore thiab offshore pipeline cov ntawv thov.
Cov yam ntxwv tseem ceeb ntawm API 5L PSL1 Seamless Yeeb Nkab
1. Cov qib thiab tshuaj / cov khoom siv mechanies
PSL1 kav yog muaj nyob rau ntau qib uas qhia txog qhov tsawg kawg ntawm cov hlau (ntsuas hauv PSI lossis MPA). Cov qib siab dua, cov yeeb nkab muaj zog.
| Teem nqi | Yam tsawg kawg nkaus xa lub zog (PSI) | Yam tsawg kawg nkaus los lub zog (Mpa) |
|---|---|---|
| A25 | 25,000 | 172 |
| A | 30,000 | 207 |
| B | 35,000 | 241 |
| X42 | 42,000 | 290 |
| X46 | 46,000 | 317 |
| X52 | 52,000 | 359 |
| X56 | 56,000 | 386 |
| X60 | 60,000 | 414 |
| X65 | 65,000 | 448 |
| X70 | 70,000 | 483 |
Tshuaj lom neeg cov tshuaj:Cov cai yuav tsum tau txwv dua PSL2. Qhov tseem ceeb yog feem ntau ntawm cov pa roj carbon (c), manganese (mn), phosphorus (p), thiab sulfur cov ntsiab lus kom ntseeg tau yooj yim thiab muaj zog.
Cov Khoom Siv Neeg Kho Tshuab:Cov tseev kom muaj ntsiab lus tseem ceeb yog qhov muaj zog
2. Kev Tsim Kho Cov Txheej Txheem
Mandrel CAV:Cov khoom siv hloov dua yog rhuab thiab tom qab ntawd chob los ntawm mandrel los tsim lub raj raj hollow (plhaub). Nws yog tom qab ntawd elongated thiab dov mus rau qhov xav tau ntawm txoj kab uas xav tau thiab phab ntsa tuab.
Lwm cov txheej txheem:Ntsaws zeb thiab extrusion kuj tau siv. Lub ntsiab lus tseem ceeb yog qhov tsis muaj ntawm kev ncua ntev los yog kev pab cuam Weld Seam.
3. Qhov zoo ntawm seamless yeeb (PSL1)
Lub zog hnav zoo li:Tsis muaj weld leeg txhais tau hais tias muaj zog sib xws nyob ib ncig ntawm txoj kev ncig.
Zoo dua rau kev kub siab:Cov qauv homogeneous ua rau nws tsis tshua muaj kev ua tsis tiav hauv siab sab hauv siab.
Kev ntseeg tau:Tshem tawm qhov kev pheej hmoo ntawm Weld Searg tsis meej.
Versatility nyob rau ntau thiab tsawg:Muaj nyob rau hauv ntau ntawm diameters thiab cov phab ntsa thicknesses, txawm tias ib txwm ua rau cov dej diam me me piv rau welded kav dej.
4. Kuaj thiab tshuaj xyuas (PSL1 yuav tsum tau)
Thaum tsis tshua ua kom nruj dua li PSL2, PSL1 tseem yuav tsum tau kuaj yuav tsum tau ua kom zoo:
Hydrostatic kev kuaj:Txhua qhov ntev ntawm cov yeeb nkab raug sim rau lub siab uas ua rau muaj kev ntxhov siab tsawg kawg ntawm 95% ntawm cov lus qhia tsawg kawg ntawm 5 feeb. Qhov no yog qhov kev ntsuas tseem ceeb rau kev ua kom muaj kev ncaj ncees.
Tsis - Kev Ntsuas Hluav Taws Xob Destructive (NDT):Rau cov yeeb nkab uas tsis muaj zog, qhov no feem ntau yog ib qhoEDDY TESTlossis ibxeem ntawv ultrasonicTxhawm rau ntes nto thiab sub - nto tsis txaus ntseeg.
Tensile xeem:Txhawm rau txheeb xyuas cov khoom siv tshuab (tawm los ntawm lub zog, elongation).
Flatenen Test / Bend Xeem:Ua rau ntawm cov qauv los ntawm cov yeeb nkab xaus los kuaj cov qauv ducility thiab suab.
Pom kev kuaj xyuas & qhov ntev:Cov tshev rau saum npoo degrom thiab tshaj tawm txoj kab uas hla, phab ntsa thickness, ovality, thiab ntev yog nyob rau hauv kev tsim txom.
Kev Sib Piv: PSL1 thiab PSL2 rau Seamless Yeeb Nkab
