Mapaipi Ozungulira Ozungulira a Mapaipi a Gasi Omwe Ali Pansi pa Dziko EN10219

Mapaipi Ozungulira Olumikizidwa a Mapaipi a Gasi Omwe Ali Pansi pa Dziko EN10219 Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Tikubweretsa mapaipi athu apamwamba kwambiri opangidwa ndi spiral welded, opangidwa kuti akwaniritse zofunikira zofunika kwambiri pakukhazikitsa mapaipi a gasi pansi pa nthaka. Mapaipi awa amapangidwa mosamala motsatira miyezo yokhwima yomwe yafotokozedwa mu EN10219, kuonetsetsa kuti zofunikira kwambiri zaukadaulo zimaperekedwa pazigawo zozizira zopangidwa ndi chitsulo chopanda aloyi ndi tirigu wabwinobwino.

Zathumapaipi ozungulira olumikizidwandi njira yabwino kwambiri yothetsera mavuto omwe kukana dzimbiri ndi kukhazikika kwa kapangidwe kake n'kofunika kwambiri. Njira yapadera yolumikizirana ndi spiral sikuti imangowonjezera mphamvu ya chitoliro, komanso imapereka malo osalala, kuchepetsa chiopsezo cha kutuluka ndi kulephera. Izi zimapangitsa kuti zikhale zoyenera kwambiri m'malo ovuta omwe nthawi zambiri amapezeka pansi pa nthaka.

Muyezo wa EN10219 umaonetsetsa kuti mapaipi athu amapangidwa molondola komanso mwaluso, kuonetsetsa kuti amatha kupirira zovuta ndi zovuta zoyendera gasi wachilengedwe. Poyang'ana kwambiri kulimba ndi kudalirika, mapaipi athu olumikizidwa mozungulira amapangidwa kuti apereke magwiridwe antchito okhalitsa, kuchepetsa kufunikira kokonza ndi kusintha pafupipafupi.

a. Njira yochotsera poizoni m'thupi imatchulidwa motere:FF: Chitsulo chophwanyika bwino chokhala ndi zinthu zomangira nayitrogeni mu kuchuluka kokwanira kumangirira nayitrogeni yomwe ilipo (monga osachepera 0,020% ya Al yonse kapena 0,015% ya Al yosungunuka). b. Mtengo wapamwamba kwambiri wa nayitrogeni sugwira ntchito ngati mankhwala akuwonetsa kuchuluka kwa Al komwe kuli 0,020% ndi chiŵerengero chochepa cha Al/N cha 2:1, kapena ngati pali zinthu zina zokwanira zomangira N. Zinthu zomangira N ziyenera kulembedwa mu Chikalata Chowunikira.

Kuwonjezera pa kapangidwe kake kolimba, mapaipi awa ndi opepuka komanso osavuta kugwiritsa ntchito, zomwe zimapangitsa kuti kukhazikitsa kukhale kogwira mtima komanso kotsika mtengo. Kaya mukuyamba ntchito yatsopano yopangira mapaipi kapena kukonza makina omwe alipo kale, mapaipi athu ozungulira amapereka kuphatikiza kwabwino kwa mphamvu, kusinthasintha, komanso kutsatira miyezo yamakampani.

Sankhani mapaipi athu ozungulira olumikizidwa kuti agwirizane ndi zosowa zanu za mapaipi a gasi pansi pa nthaka ndipo khalani ndi mtendere wamumtima womwe umabwera pogwiritsa ntchito zinthu zomwe zimakwaniritsa zosowa zanu.EN10219miyezo. Khulupirirani kudzipereka kwathu pa khalidwe ndi magwiridwe antchito kuti titsimikizire chitetezo ndi magwiridwe antchito a gasi yanu.

Yapitayi: Mapaipi achitsulo cha kaboni cholumikizidwa mozungulira cha mapaipi a gasi wachilengedwe pansi pa nthaka - EN10219
