Mapaipi Owotcherera Ozungulira a Mapaipi Apansi Pansi pa Gasi EN10219

Mapaipi Owotcherera Ozungulira a Mapaipi Apansi Pansi Pansi EN10219 Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Kuyambitsa mapaipi athu apamwamba kwambiri opangidwa ndi spiral welded, opangidwa kuti akwaniritse zofunikira pakuyika mapaipi apansi panthaka. Mapaipiwa amapangidwa mosamalitsa motsatira mfundo zokhwima zomwe zakhazikitsidwa mu EN10219, kuwonetsetsa kuti pakufunika ukadaulo wapamwamba kwambiri pazigawo za dzenje lozizira lopangidwa mozizira muzitsulo zopanda aloyi komanso zitsulo zambewu zabwino.

Zathumipope yozungulira yozungulirandi njira yabwino yothetsera mapulojekiti omwe kukana kwa dzimbiri ndi kusakhazikika kwadongosolo ndikofunikira. Kuwotcherera kwapadera kwa spiral sikungowonjezera mphamvu ya chitoliro, komanso kumapereka malo osasunthika, kuchepetsa chiopsezo cha kutulutsa ndi kulephera. Izi zimawapangitsa kukhala oyenera makamaka kumadera ovuta omwe nthawi zambiri amakumana nawo pamagwiritsidwe apansi panthaka.

Muyezo wa EN10219 umatsimikizira kuti mapaipi athu amapangidwa mwatsatanetsatane komanso mwaluso, kuwonetsetsa kuti atha kupirira zovuta ndi zovuta zamagalimoto a gasi. Poyang'ana pa kulimba ndi kudalirika, mapaipi athu ozungulira amapangidwa kuti azigwira ntchito kwanthawi yayitali, kuchepetsa kufunika kokonzanso pafupipafupi komanso kusinthidwa.

a. Njira ya deoxidation imayikidwa motere:FF: Chitsulo chophedwa kwathunthu chokhala ndi zinthu zomangira za nayitrogeni mu kuchuluka kokwanira kumanga nayitrogeni yomwe ilipo (mwachitsanzo min. 0,020 % okwana Al kapena 0,015 % sungunuka Al). b. Mtengo wapamwamba wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al zomwe zili 0,020 % ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati zinthu zina zokwanira za N-binding zilipo. Zinthu zomangiriza za N zidzalembedwa mu Inspection Document.

Kuphatikiza pa zomangamanga zake zolimba, mapaipiwa ndi opepuka komanso osavuta kunyamula, zomwe zimapangitsa kuti kuyikako kukhale kogwira mtima komanso kotsika mtengo. Kaya mukupanga pulojekiti yatsopano yopangira mapaipi kapena mukukweza makina omwe alipo, mapaipi athu ozungulira amakupatsirani mphamvu, kusinthasintha, komanso kutsata miyezo yamakampani.

Sankhani mapaipi athu ozungulira ozungulira kuti mukwaniritse zosowa zanu zamapaipi apansi panthaka ndikukhala ndi mtendere wamumtima womwe umabwera pogwiritsa ntchito zinthu zomwe zimakwaniritsaEN10219miyezo. Khulupirirani kudzipereka kwathu pakuchita bwino ndi magwiridwe antchito kuti muwonetsetse chitetezo ndi magwiridwe antchito amafuta anu.
