EN 10255 Cov Hlau Hlau Tube Hnyav Thiab Nruab Nrab Series:
Cov txheej txheem tsim khoom
Mainstream kev tsim khoom lag luam
EN 10255 Cov Kav Hlau Steeltsuas yog tso cai kom tsim tau siv "txheej txheem vuam." Cov txheej txheem tseem ceeb tau muab faib ua ob pawg, haum rau ntau qhov ntau thiab tsawg thiab ua kom zoo:
Hluav Taws Xob Ua Chiv Hlau (ERW):Haum rau cov kav dej nrog txoj kab uas hla ntawm tsawg dua lossis sib npaug rau 219mm. Siab - zaus} zaus tam sim no yog siv los ua kom sov lub steel yeeb nkab ntug thiab tom qab ntawd nyem thiab nyem. Weld lub zog yog ntau dua los yog sib npaug rau 90% ntawm lub hauv paus khoom siv lub zog. Tus txheej txheem no muaj ntau cov kev ua tau zoo thiab tswj hwm. Nws yog feem ntau siv hauv kev thauj mus los hauv nroog / roj tsheb thauj mus los.
Arc vuam (pom / paw):Haum rau loj - txoj kab uas hla nrog txoj kab tawm sab nraud ntau dua 219mm. Submerged arc vuam (pom) muaj tob vuam nkag thiab yog qhov tsim nyog rau kev lag luam tsawg (xws li cua txias kav dej).
Kev Soj Ntsuam Zoo
Cov tsos tshuaj tshuaj xyuas:Tsis muaj kab nrib pleb, quav, nti, lossis delamination rau saum npoo. Kev xeb tsawg dua li lossis sib npaug rau 10% ntawm phab ntsa tuab. Weld protrusion qhov siab tsawg dua los yog sib npaug ntawm 2 hli (erw yeeb nkab).
Tshuaj Ntsuam Xyuas Sab Nrau:Ntsuas cov taub txheej txheej sab nraud, phab ntsa thickness, thiab ovality ntawm txhua cov yeeb nkab kom ntseeg tau nrog EN 10255 thev naus laus zis.
Kev Kuaj Neeg Kho:Peb cov hnoos qeev tau sib piv los ntawm txhua pob thiab raug rau Tensile thiab Bend Chancinal thiab khoov kaum-{1}} x phab ntsa tuab). Kev txais yog txiav txim siab los ntawm qhov tsis muaj cov kab nrib pleb.
HYDRAULIC SIAB TESTING:Tag nrho cov kav dej yauv mus ua hydOSTATIC (sim siab=2 u tsim 30 vib nas this nrog tsis muaj leakage). Tus tsim qauv siab yog xam raws ntawm phab ntsa thickness thiab hom.
Weld Soj ntsuam:ERW pipes undergo eddy current testing (100% weld inspection), while arc-welded pipes undergo X-ray testing (sampling inspection ratio>=10%) to detect internal weld defects.
Qhia Xaiv Kev Xaiv
Rau qis - siab kis (tsawg dua los yog sib npaug rau 1.6 MPa, xws li dej / roj), P195tr1 (ERW cov txheej txheem) yog nyiam rau tus nqi zoo tshaj plaws- ua hauj lwm zoo. Txog kev txias dabtsi yog khoov (piv txwv li, nyob rau -}}} chaw seem dabtsi yog tab tom txhim kho), xaiv P195TR2.
Rau tsawg -} nruab nrab siab (1.6-} 2.5 mpa, xws li cov pa qis):Choose P235TR1 (ERW for outer diameters ≤219 mm, SAW for diameters >219 hli). Rau cov kua dej ua kua (piv txwv li, dej txias), xaiv p235tr2 rau kev txhim kho kev qaug zog tsis kam.
Rau kev xeb ib puag ncig (piv txwv li, sab nraum zoov thaj chaw, cov chaw muaj chaw muaj huab cua ntub):Kub - dip galvanized en 10255 txheej txheem steel (galvanized txheej ntau dua los yog sib npaug
For large diameters (>273 hli), P235tr1 / tr2 nrog submerged arc vuam (pom) yuav tsum ua kom muaj weld lub zog thiab yeeb nkab ruaj khov.
Cov raj loj muaj xws li en 10255 carbon hlau raj, en 10255 welded steel raj, en 10255 L1 Series Hlau Tube, thiab EN 10255 L2 Series Steel Tube.
En 10255 carbon hlau yeeb nkab, nrog nws cov txiaj ntsig ntawm "cov nqi verdability, thiab kev xaiv zoo nkauj rau cov kev thauj tsawg - bearing scenararios. Nws tuaj yeem phim cov qhab nia thiab cov txheej txheem raws li siab, ib puag ncig, thiab loj yuav tsum muaj kev nyab xeeb thiab tus nqi- ua hauj lwm zoo.
