Makina osiyanasiyana okhazikika amapereka mawonekedwe osiyanasiyana ogwiritsira ntchito, ndipo kuyang'ana kwa chitoliro cha chitoliro sikufanana.
Lero tikambirana za EN standard system ya EN10220.
Mwachidule za muyezo wa EN 10220
EN 10220ndi muyezo waku Europe wa miyeso ndi kulolerana kwa mapaipi opanda zitsulo ndi welded.
Muyezo wa EN 10220 uli ndi ntchito zosiyanasiyana ndipo umagwiritsidwa ntchito makamaka m'mafakitale opangira mafuta, gasi, mankhwala, zomangamanga, ndi zoyezera madzi.
Muyezowu umaphatikizapo m'mimba mwake (OD) ndi makulidwe a khoma (WT) a mapaipi achitsulo, opereka malangizo omveka bwino komanso mawonekedwe ofanana a kapangidwe ka uinjiniya ndi kupanga kuti zitsimikizire kusasinthika komanso kusinthana kwa zinthu zapaipi zopangidwa ndi opanga osiyanasiyana.
Njira Zowerengera Kulemera
Njira yowerengera misa pa mita pa kutalika kwa unit imaperekedwa mu EN 10220.
M=(DT)×Tx0.0246615
Mkulemera kwa unit kutalika mu kg/m,
Dndi m'mimba mwake wakunja kwa mm,
Tndi makulidwe a khoma lotchulidwa mm.
Izi zimachokera ku kachulukidwe ka 7.85 kg / dm3.(kg/dm3ndi unit of density, cubic decimeters.)
Miyezo yowerengeredwa itha kugwiritsidwanso ntchito ku machubu okhala ndi makulidwe osiyanasiyana, koma ayenera kuchulukitsidwa ndi chinthu cha
1.015 ya chitsulo chosapanga dzimbiri cha austenitic (Chinthu ichi chimachokera pa kachulukidwe ka 7.97 kg/dm3）.
0.985 ya chitsulo chosapanga dzimbiri cha ferritic ndi martensitic (Chinthu ichi chimachokera ku kachulukidwe ka 7.73 kg/dm3）.
Kuwerengera kumatha kupangidwa motengera kuchuluka kwa kachulukidwe kosiyanitsidwa pagulu lililonse lazitsulo zosapanga dzimbiri zoperekedwa mu EN 10088-1.
EN 10220 Series Gulu
EN 10220malinga ndi mlingo wa standardization wa mapaipi ndi Chalk awo.Pali mitundu itatu.
mndandanda 1: ma diameter akunja omwe zida zonse zofunika pakumanga mapaipi zimakhazikika;
mndandanda 2: ma diameter akunja omwe sizinthu zonse zomwe zimakhazikika;
mndandanda 3: ma diameter akunja omwe pali zida zochepa zokhazikika.
Ma chart a pipe kulemera kwa EN 10220 Series 1
Chitoliro cha OD cha mndandandawu chimatsatira miyezo yapadziko lonse kapena yamakampani ndendende, ndipo msika umapereka zolumikizira zokhazikika monga ma flanges, ma couplings, ndi zigongono.
Kukhazikika kokwanira kumeneku kumathandizira kamangidwe ndi kukhazikitsa ndikuchepetsa kufunikira kwa magawo omwe si oyenera komanso ndalama zosinthira.
Kulemera kwa mapaipi a EN 10220 Series 2
Gawo la OD la mtundu uwu wa mapaipi ndi lokhazikika, koma sizinthu zonse zomwe zimakhala zokhazikika.Zopangira zina zokhazikika, monga ma flanges kapena zigongono, zitha kupezeka, pomwe zida zina zingafunikire kusinthidwa mwamakonda, ndikuwonjezera mtengo ndi zovuta za polojekitiyo.
Ma chart a pipe kulemera kwa EN 10220 Series 3
Izi nthawi zambiri zimakhala ndi miyeso yeniyeni kapena yosagwirizana ndi mipope yomwe imafuna kuchuluka kwa zida zopangira makonda ndi zigawo zikuluzikulu, kukweza mtengo wokonza ndi kukhazikitsa polojekitiyi, komanso kukulitsa nthawi yogula ndi kupanga.
Ma chart a Kulemera kwa Chitoliro kwa Makulidwe a Khoma 70 -100 mm
Kwa machubu okhala ndi mipanda yokhuthala okhala ndi makulidwe a khoma kuyambira 70 mm mpaka 100 mm, zofunikira zimafotokozedwa mu EN 10220, Gulu 2.
Zida zamachubu olemera a khoma okhala ndi miyeso molingana ndi Table 2 mwina sizingakhalepo mosasamala kanthu za mndandanda womwe uli mu Gulu 1 pomwe mainchesi ofunikira akunja amaperekedwa.
Ndife apamwamba welded mpweya zitsulo chitoliro wopanga ndi katundu kuchokera China, komanso msokonezo zitsulo chitoliro stockist, kukupatsani osiyanasiyana zitsulo chitoliro njira!
