Dab tsi yog 1.7335 Seamless Steel Pipe?
1.7335 yog tus naj npawb ntawm cov khoom siv, tseem hu ua Werkstoff tooj, ntawm chromium-molybdenum steel 13CrMo4-5 hauv DIN thiab EN qhov system npe. A 1.7335 seamless steel yeeb nkab yog ib lub raj tsim tsis muaj longitudinal los yog kauv weld, yog li cov yeeb nkab tiav lawm muaj lub zog tsis sib xws thiab phab ntsa tuab nyob ib ncig ntawm tag nrho cov ncig. Qib yog tus qauv hauv EN 10216-2, uas npog seamless steel raj rau lub hom phiaj siab ntawm qhov kub siab.
Vim li cas Seamless Construction Matters
Qhov tsis muaj weld seam tshem tawm qhov tsis muaj zog tshaj plaws ntawm lub raj welded. Seamless yeeb nkab muaj lub zog tsis sib xws hauv txhua qhov kev qhia, zoo dua tiv thaiv sab hauv thiab sab nraud, cov phab ntsa tuab zoo ib yam, thiab qhov tseeb qhov tseeb. Rau siab - siab boiler thiab refinery kev pab cuam, cov qualities yuav txo tau qhov kev pheej hmoo ntawm tsis ua hauj lwm ntawm lub seam thiab ua kom yooj yim rau kev tsim qauv.

Txoj kev tsim khoom
Seamless yeeb nkab yog tsim los ntawm kub ua hauj lwm ib tug khoom billet. Lub billet yog rhuab thiab pierced los ua ib tug hollow plhaub, uas yog ces elongated los ntawm dov los yog kos duab mus rau lub kawg txoj kab uas hla thiab phab ntsa thickness. Cov yeeb nkab kub tiav tuaj yeem siv ncaj qha tom qab kev kho cua sov, thaum cov yeeb nkab txias txias yog tsim rau kev ua kom nruj dua, cov phab ntsa nyias nyias, thiab zoo dua qhov chaw tiav. Ob txoj hauv kev xa cov xwm txheej zoo li qub thiab tempered xav tau rau qib.
Ordering Information
Thaum xaj 1.7335 seamless yeeb nkab, qib ib leeg tsis txaus. Sab nraud txoj kab uas hla, phab ntsa thickness, ntev, kev xa khoom, thiab cov qauv siv tau yuav tsum tau sau tseg. Rau kev siv siab, hom ntawv pov thawj tshuaj xyuas yuav tsum tau pom zoo, feem ntau daim ntawv pov thawj 3.1 rau EN 10204.
Tej kev siv
1.7335 seamless yeeb nkab yog siv nyob rau hauv boiler superheaters thiab reheaters, feedwater heaters, siab - siab chav kab, thiab tshav kub exchanger raj. Kev lag luam petrochemical siv nws rau cov kav dej hauv hydroprocessing thiab lwm yam kev pabcuam kub siab. Daim ntawv seamless yog qhov nyiam rau cov ntawv thov no vim nws lub peev xwm siab tsis sib xws thiab ntev -lub sij hawm nkag mus.
FAQ
Puas yog 1.7335 tib yam li 13CrMo4-5?
Yog . 1.7335 yog cov khoom siv tooj thiab 13CrMo4-5 yog qib npe ntawm tib lub hlau. Ob qho kev xaiv tshwm sim ntawm daim ntawv pov thawj, thiab tuaj yeem siv tau thaum xaj.
Qhov kev pabcuam siab tshaj plaws yog dab tsi?
Kev pabcuam txuas ntxiv yog ib txwm txwv rau li 550 degrees Celsius. Tshaj qhov ntsuas kub no, tus qauv tsim yuav tsum txav mus rau qib siab chromium xws li 10CrMo9-10 lossis 9Cr-1Mo steels.
Puas yog seamless 1.7335 yeeb nkab yuav txias kos?
Yog lawm. Kev kos duab txias txhim kho qhov tseeb qhov tseeb thiab qhov chaw tiav thiab yog siv rau nyias - cov phab ntsa thiab cov raj. Cold drawn tubes raug kho kom sov tom qab qhov kawg daim duab dhau.
Yuav tsum muaj daim ntawv pov thawj tshuaj xyuas dab tsi?
Rau kev pabcuam siab, kev tshuaj xyuas daim ntawv pov thawj 3.1 rau EN 10204 muab los ntawm cov chaw tsim khoom yog tus qauv. Nws sau cov ntaub ntawv tshuaj ntsuam xyuas thiab kev ntsuas kev ntsuas ntawm cov khoom xa tuaj.
Puas yog cov yeeb nkab weldable?
Yog, cov hlau yog weldable los ntawm cov txheej txheem arc txheej txheem nrog preheat rau cov seem tuab. Tom qab-weld kev kho cua sov yog ib txwm xav tau rau qhov chaw siab kom rov ua kom tawv tawv hauv tshav kub- thaj tsam cuam tshuam.
Qhov ntau thiab tsawg yog muaj?
Seamless 1.7335 yeeb nkab yog muaj los ntawm me me - txoj kab uas hla ntawm 20 mm mus rau loj - txoj kab uas hla ntawm 600 mm los yog ntau dua, nrog rau phab ntsa thicknesses xaiv raws li tus tsim siab. Qhov ntev yog feem ntau muab los ntawm 6 m txog 12 m.
