API 5L L360 Pipe yog dab tsi?
L360 yog lub npe metric rau API 5L X52: micro-alloyed carbon steel kab yeeb nkab nrog ib qho kev qhia tsawg kawg nkaus lub zog ntawm 360 MPa (52,000 psi). Nws tuaj yeem tsim ua seamless (SMLS) lossis welded, thiab hauv PSL1 lossis PSL2 qib zoo. Lub seamless version yog qhov zoo dua qhov siab siab, txoj kab uas hla yog nruab nrab, thiab kev ntseeg siab ntawm cov yeeb nkab lub cev yog qhov tseem ceeb heev -vim qhov tsis muaj qhov ntev ntawm seam tshem tawm cov weld raws li qhov txuas tsis muaj zog.
Kev lag luam roj thiab roj
Lub zog sector yog thawj tus neeg siv khoom ntawm L360 seamless yeeb nkab:
Zoo sib sau ua ke thiab flow kab:
txav cov roj av thiab cov nkev ntuj los ntawm lub qhov dej mus rau qhov chaw ua haujlwm ntawm qhov siab txog li 10 MPa lossis ntau dua.
Lub cev thiab kis kab mob:
L360 PSL2 seamless yeeb nkab yog dav siv rau lub regional gas kis qhov twg diameters txog li 400 hli yog txaus.
Compressor thiab twj tso kua mis chaw nres tsheb:
nyob rau hauv - cog piping thiab headers uas yuav tsum zam kev vibration, surge thiab rov siab cycling.
Oilfield txhaj kab:
dej thiab tshuaj txhaj cov kev pab cuam qhov twg lub zog thiab to{0}} nruj yog qhov tseem ceeb.
Lub Nroog Gas thiab Utilities
Cov pa roj hauv nroog feem ntau qhia L360 rau siab - cov khoom siv hluav taws xob siab thiab cov khoom siv nyob deb nroog, sib txuas lub zog los tiv thaiv qhov thib peb - tog kev cuam tshuam nrog thaj chaw zoo weldability. Cov qib tib yam tshwm sim hauv compressed natural gas (CNG) chaw nres tsheb piping thiab hauv nroog nruab nrab- cov tes hauj lwm siab uas lub seamless bore txo qhov kev pheej hmoo ntawm to.
Dej thiab Infrastructure
Txawm hais tias cov qib qis dua muaj nyob rau hauv kev pabcuam dej, L360 raug xaiv thaum faus qhov tob, kev thauj khoom sab nraud lossis qhov siab siab xav tau lub zog ntxiv:
Cov dej tsis huv thiab kho cov dej xa hluav taws xob.
Cov dej txias hauv cov hluav taws xob hluav taws xob.
Hydroelectric penstock thiab siab tunnel liners nyob rau hauv me me diameters.
Irrigation pumping mains nrog lub taub hau ua haujlwm siab.
Fais fab thiab Petrochemical Cog
Nyob rau hauv refineries, tshuaj nroj tsuag thiab fais fab chaw nres tsheb, L360 seamless yeeb nkab yog siv rau cov txheej txheem kab, chav thiab condensate headers, thiab cov kav dej siv qhov twg kub nyob rau hauv lub hnab ntawv carbon steel (kwv yees li 400 degree). Nws lub zog muaj zog ntau dua tso cai rau cov phab ntsa nyias dua li Qib B, txuag qhov hnyav ntawm cov yeeb nkab racks thiab kev txhawb nqa.
Kev siv cov qauv thiab tshuab
Kev pabcuam dej sab nraud, L360 yog siv rau kev sib tsoo, kev sib tsoo, cov khoom siv conveyor thiab cov khoom siv tshuab uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo ntawm seamless. Sour -cov kev pabcuam txawv (L360QS) muaj nyob rau hauv ib puag ncig hydrogen sulfide thiab yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm hardness thiab HIC xeem.

Cov lus nug nquag
Puas yog L360 tib qib li X52?
Yog lawm. L360 yog SI-unit designation; X52 yog lub npe imperial siv nyob rau hauv API 5L, ob lub ntsiab lus 360 MPa (52,000 psi) yam tsawg kawg nkaus yield zog.
Thaum twg kuv yuav tsum xaiv seamless welded L360 yeeb nkab?
Xaiv seamless rau kev kub siab, me me mus rau nruab nrab diameters, qaub kev pab cuam, thiab daim ntawv thov qhov uas tsis muaj ib tug longitudinal weld seam yog tsim los yog kev tswj kom zoo dua.
L360 puas tuaj yeem siv rau cov dej haus?
Yog lawm, nrog rau kev pom zoo sab hauv hauv ob sab phlu lossis txheej thiab pov thawj tias cov khoom ua tau raws li cov khoom siv hauv zos - cov cai tswj dej.
Dab tsi yog qhov ntsuas kub rau L360 seamless yeeb nkab?
Raws li cov pa roj carbon-manganese hlau, kev pabcuam txuas ntxiv feem ntau txwv rau li 400℃; saum toj no, creep-resistant alloy steels yuav tsum tau.
Puas muaj qaub -kev pabcuam L360?
Yog lawm, tsim L360QS hauv API 5L, nrog kev txwv hardness, HIC kuaj thiab nruj chemistry rau hydrogen sulfide ib puag ncig.
Puas yog L360 PSL2 xav tau kev sim cuam tshuam?
Yog lawm. PSL2 yuav tsum tau Charpy V- qhov ntsuas qhov cuam tshuam, thiab cov phiaj xwm xa hluav taws xob feem ntau ntxiv kev poob - hnyav kua muag ntsuas raws li qhov yuav tsum tau ua ntxiv.
