(D400) EN124 Txoj Kev Gully Npog Round Ductile Hlau Manhole Npog thiab Ncej
Kev tshuaj xyuas manhole npog hauv qab txoj kev taug kev, thiab qib D400 ntawm lub rooj zaum manhole yog lub nroog txoj kev loj, txoj kev loj, txoj kev loj thiab lwm qhov chaw.
Rau kev siv ntawm txoj kev, tsawg kawg yog qhov kev xeem ntawm 36 tons tau teev nyob rau hauv "Cast Iron Manhole Cover" tus qauv yuav tsum mus txog.
Nrog rau txoj kev loj hlob ntawm cov nroog, txoj kev tau txais kev dav thiab dav, cov tsheb thauj mus los tau nce zuj zus, lub peev xwm thauj khoom tau nce siab dua, thiab cov kev xav tau ntawm cov kabmob ntawm lub manhole npog tau nce siab dua.Yog li ntawd, manhole npog ua los ntawm cov ntaub ntawv tshiab yuav tsum tsis tsuas yog ua tau raws li tus txheej txheem "cam khwb cia hlau manhole npog" uas twb muaj lawm, tab sis kuj dhau tus qauv no.Yog tias tus qauv npog manhole tshiab yuav tsum tau tsim, nws raug pom zoo tias kev faib tawm thiab cov kev cai ntawm cov kabmob muaj peev xwm yuav tsum xa mus rau European tus qauv EN124, thiab lub peev xwm thauj khoom ntawm manhole npog siv rau lub tsheb yuav tsum tsis txhob tsawg dua. ua 40t!
Standard loj ntawm manhole npog
Qhov loj ntawm lub hau npog feem ntau yog 600mm, 700mm thiab 800mm.Feem ntau hais lus, lub manhole npog ntawm 600 txhais tau hais tias txoj kab uas hla ntawm lub npog yog 600. Tom qab ntawd txoj kab uas hla ntawm qhov qis ntawm cov pejxeem yuav tsum tsawg dua 600, thiab nws yuav yog 550 nyob rau hauv ib txwm muaj xwm txheej.
Txog
Qhov zoo ntawm D400 ductile hlau manhole npog, zoo toughness.Tus nqi cuam tshuam zoo ib yam li cov pa roj carbon nruab nrab, ntau dua 10 npaug ntawm cov hlau grey.Muaj zog corrosion kuj.Nyob rau hauv cov dej tshuaj tsuag corrosion test, tus nqi ntawm corrosion nyob rau hauv 90 hnub tsuas yog 1/40 ntawm cov kav hlau thiab 1/10 ntawm cov kav hlau grey.Lub neej kev pabcuam yog ob zaug ntawm cov kav hlau grey thiab 5 npaug ntawm cov kav hlau zoo tib yam.Zoo plasticity.Qhov elongation tus nqi yog ≥7%, uas zoo ib yam li cov hlau carbon siab, thaum lub elongation tus nqi ntawm grey hlau cov ntaub ntawv yog xoom.siab zog.Tensile lub zog ób≥420MPa, tawm lub zog ós≥300MPa, uas yog tib yam li cov pa roj carbon tsawg thiab peb npaug ntawm cov khoom siv hlau grey.Muaj ntau hom manhole npog, xws li H composite cover, composite cover, pe cover, stainless steel cover, ductile hlau cover, resin composite well groove, stainless steel cover, thiab lwm yam. Lub sij hawm compression molding tshuab, nrog rau qib siab ntawm polymerization, siab ceev, zoo cuam tshuam tsis kam thiab tensile lub zog, thiab muaj qhov zoo ntawm hnav tsis kam, corrosion kuj, tsis xeb, tsis muaj kuab paug, thiab tu-dawb.Nws yog dav siv hauv kev tsim kho hauv nroog, kev tsim vaj tsev, vaj tsev, lub zog, hluav taws xob, kev sib txuas lus, kev thauj mus los ntse thiab lwm yam.
