Dab tsi ua rau PSL2 txawv
API 5L txhais ob yam khoom tshwj xeeb rau kab yeeb nkab. PSL2 yog qib txhim khu kev qha, tsim los rau siab - kev sib kis siab, qis- kev pabcuam kub, cov tshuab tawm sab nrauv thiab cov neeg nyob hauv qhov chaw uas tawg tawg lossis vuam tsis ua haujlwm yuav muaj qhov tshwm sim loj.
Lub ntsiab lus ntawm PSL2 yog qhov toughness tsis yog xaiv tau. Txhua qhov cua sov thiab phab ntsa tuab ua ke yuav tsum dhau Charpy V- qhov ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas kub, nrog qhov nruab nrab nruab nrab lub zog thiab qhov tsawg kawg nkaus ib qho tseem ceeb tau teev tseg hauv tus qauv. Qhov no ncaj qha hais txog kev pheej hmoo ntawm kev tawg tawg hauv kev pabcuam.
Cov ntsiab lus tseem ceeb PSL2
| Kev xav tau | PSL2 Tus nqi |
|---|---|
| Charpy impact test | Yuav tsum tau nyob ntawm qhov ntsuas kub |
| Carbon sib npaug, max | Txhais ib qib, feem ntau 0.43 CE |
| Carbon, max rau Qib B | 0.24% |
| Sulfur, max | 0.015% |
| Phosphorus, max | 0.025% |
| Yield rau tensile ratio, max | 0.93 rau feem ntau qib |
| Traceability | Thaum tshav kub kub tus lej cim ntawm txhua lub yeeb nkab |
Cov pa roj carbon sib npaug yog xam los ntawm kev ntsuas cua sov uas siv cov qauv IIW lossis Pcm. Qhov sib npaug ntawm cov pa roj carbon tsawg txhais tau hais tias cov yeeb nkab tuaj yeem txuas rau hauv qhov chaw uas muaj kev pheej hmoo tsawg ntawm hydrogen-induced txias cracking, uas yog qhov tseem ceeb rau kev tsim kho mainline.
Qib thiab Kev Tsim Khoom
PSL2 npog Qib B thiab X series txog X80 thiab tshaj. Cov yeeb nkab yuav seamless los yog welded los ntawm ERW, LSAW lossis SSAW txheej txheem. Rau qib X60 thiab siab dua, qhov siab tshaj plaws ntawm kev ntsuas hydrostatic tsuas yog txwv rau 95 feem pua ntawm cov khoom muaj zog, thiab cov kev xav tau ntxiv rau hardness, NDT thiab qaub cov kev pabcuam tuaj yeem muab ntxiv.
Daim ntawv thov ntawm PSL2 Pipe
PSL2 cov pa roj carbon steel yeeb nkab yog siv rau hauv cov roj xa hluav taws xob tseem ceeb, cov roj av roj av, cov kav dej tawm sab nrauv thiab cov kav dej hauv qab, cov kab kev pabcuam hauv Arctic, siab -siab sib sau ua ke thiab txhua txoj kab tswj hwm los ntawm cov phiaj xwm tawg. Nws tseem yog lub hauv paus rau kev pabcuam qaub thaum ua ke nrog NACE MR0175 cov cai.
FAQ
Q1. PSL2 txhais li cas?
PSL2 txhais tau hais tias Cov Khoom Qhia Tshwj Xeeb Qib 2, kev txhim kho qib ntawm API 5L nrog rau qhov yuav tsum tau kuaj toughness, nruj chemistry thiab tag nrho traceability rau siab - kev ncaj ncees pipeline kev pab cuam.
Q2. Vim li cas thiaj li yuav tsum tau kuaj xyuas hauv PSL2?
Kev ntsuam xyuas cuam tshuam tau lees paub tias cov khoom siv yeeb nkab absorbs lub zog txaus ntawm qhov ntsuas kub tsim los tiv thaiv cov pob txha tawg, uas yog qhov tseem ceeb tsis ua hauj lwm hauv cov kav dej.
Q3. Dab tsi yog carbon sib npaug thiab vim li cas nws tseem ceeb?
Carbon sib npaug yog xam qhov ntsuas ntawm weldability. Tus nqi qis dua qhia tias tsis tshua muaj kev pheej hmoo ntawm qhov txias txias thaum lub sij hawm welding, yog li PSL2 txwv nws los tiv thaiv weld kev ncaj ncees.
Q4. Cov qib twg muaj nyob hauv PSL2?
Txhua qib API 5L muaj nyob rau hauv PSL2, los ntawm Qib B txog X42, X52, X60, X65, X70 thiab X80, hauv cov ntawv seamless thiab welded.
Q5. Puas yog PSL2 yeeb nkab xav tau rau kev pabcuam qaub?
Sour kev pabcuam ib txwm xav tau PSL2 raws li cov hauv paus ntsiab lus ntxiv rau cov kev xav tau ntxiv xws li kev txwv hardness thiab HIC kuaj ib NACE TM0284 thiab NACE MR0175.
Q6. PSL2 cuam tshuam tus nqi yeeb nkab li cas?
PSL2 ntxiv tus nqi los ntawm kev ntsuam xyuas kev cuam tshuam, kev tswj hwm kev tswj hwm thiab cov ntaub ntawv nruj dua. Tus nqi them yog tsim nyog los ntawm kev ncaj ncees siab dua thiab kev nyab xeeb ntawm nws xa.
