API 5L X52 SAW Kab Yeeb
X52 SAW kab yeeb nkabyog cov khoom siv dav siv hauv cov khoom siv roj thiab roj, muab faib ua cov khoom siv raws li API 5L tus qauv. Lub npe X52 qhia txog qhov tsawg kawg nkaus tawm lub zog ntawm52,000 psi (kwv yees li 358 MPa), categorizing nws raws li qhov nruab nrab - zog pipeline steel.
Tshuaj muaj pes tsawg leeg
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm X52 muaj feem ntau ntawm cov pa roj carbon thiab manganese ua cov ntsiab lus tseem ceeb, nrog cov lej ntawm silicon, phosphorus thiab sulfur. Los ntawm kev tswj dov thiab txias cov txheej txheem, X52 ua tiav lub zog sib npaug thaum tuav cov tawv zoo thiab weldability. Micro-alloying cov ntsiab lus xws li vanadium, niobium thiab titanium ua kom zoo dua cov qauv nplej kom txhim kho qis- qhov kub thiab txias cuam tshuam toughness.

Daim ntawv thov
X52 SAW yeeb nkab yog siv rau hauv piling, roj thiab roj kis tau tus mob, dej thiab cov kev pab cuam dav dav, qhov twg nws ua ke ntawm lub zog, weldability thiab nqi efficiency ua rau nws ib tug nyiam specification.
Cov lus nug nquag
X52 txhais li cas?
Nws tsim lub zog tsawg kawg nkaus ntawm 52,000 psi (kwv yees li 358 MPa) raws li API 5L.
Qhov txawv ntawm SAW thiab SSAW yog dab tsi?
SAW yog cov dav dav submerged arc vuam tsev neeg; SSAW yog lub kauv variant. X52 SAW yeeb nkab nyob rau hauv no specification yog tsim raws li SSAW.
Cov qauv twg npog X52 SAW yeeb nkab?
API 5L, ASTM A252, ASTM A53 thiab GB / T 9711, thiab lwm yam.
X52 SAW yeeb nkab puas tuaj yeem yog 3PE coated?
Yog lawm, 3PE, epoxy hmoov thiab pleev xim rau saum npoo yog cov qauv kev xaiv rau kev muab faus.
PSL2 mechanical txwv yog dab tsi?
Rau X52N, tawm los 360-530 MPa, tensile 460-760 MPa thiab Y / T ratio max 0.93.
Vim li cas V, Nb thiab Ti ntxiv?
Cov micro-alloys no kho cov qauv nplej, txhim kho lub zog thiab qis-kub toughness yam tsis muaj teeb meem weldability.
