Spiral Welded Steel Pipe Kwa Mphamvu Zosayerekezeka Ndi Kuchita Bwino ASTM A252

Spiral Welded Steel Pipe Ya Mphamvu Zosayerekezeka Ndi Kuchita Bwino kwa ASTM A252 Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Izi ndikupereka muyezo wopangira mapaipi operekera madzi, gasi ndi mafuta m'mafakitale amafuta ndi gasi.

Pali magawo awiri amtundu wazinthu, PSL 1 ndi PSL 2, PSL 2 ili ndi zofunikira zofananira ndi kaboni, kulimba kwa notch, mphamvu zokolola zambiri komanso kulimba kwamphamvu.

Tsegulani:

Pankhani ya chitukuko cha zomangamanga, machitidwe a mapaipi ndi gawo lofunikira lomwe limagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana.Kugwiritsa ntchito zipangizo ndi njira zoyenera pomanga zitoliro zimatsimikizira kulimba, mphamvu ndi kudalirika, ndiwozungulira welded zitsulo chitoliro ASTM A252ali patsogolo pa kupita patsogolo kwaukadaulo kumeneku.Mu blog iyi, tiwona mozama za mikhalidwe yapadera komanso ubwino wa mapaipi odabwitsawa omwe akhala ofunika kwambiri pantchito zomanga zamakono.

Mphamvu Zosayerekezeka ndi Kukhalitsa:

ASTM A252wozungulira welded zitsulo chitoliroamapangidwa ndi zitsulo zapamwamba kwambiri zomwe zimakwaniritsa miyezo ya ASTM A252.Muyezowu umatsimikizira mphamvu zapamwamba komanso kulimba kwa mapaipi, kuwapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana kuphatikiza kutumizira mafuta ndi gasi, kuyika maziko ndi zomangamanga zamadzi.Ma welds ozungulira amawonjezera mphamvu ndi kukana kwa mapaipi ku mphamvu zakunja, kuwonetsetsa kuti atha kupirira malo opanikizika kwambiri komanso nyengo yoyipa.

Kuchita bwino kwambiri komanso kutsika mtengo:

Chimodzi mwazabwino zazikulu za ASTM A252 spiral welded steel pipe ndikuchita bwino kwambiri pakuyika ndikugwiritsa ntchito.Mapangidwe ake ozungulira ndi osavuta kunyamula ndikuwongolera chifukwa cha kulemera kwake kopepuka poyerekeza ndi zida zina zapaipi.Kuonjezera apo, kusinthasintha kwa mapaipiwa kumathandizira kupindika, kuchepetsa zofunikira zazitsulo ndi zolumikizira.Sikuti izi zimangopulumutsa nthawi, zimachepetsanso kwambiri ndalama zoyikira, zomwe zimapangitsa kuti ma ductwork amtunduwu akhale otsika mtengo pama projekiti osiyanasiyana.

Kuchuluka kwa corrosion resistance:

Kuwonongeka ndi vuto lalikulu m'mapaipi, makamaka m'mafakitale omwe amagwiritsa ntchito mankhwala ndi zinthu zowononga.Muyezo wa ASTM A252 umatsimikizira kuti mapaipi achitsulo ozungulira amawonetsa kukana kwa dzimbiri.Mapaipiwa ali ndi zokutira zoteteza monga epoxy kapena zinc zomwe zimakhala ngati chotchinga kwa zinthu zowononga, kuwonjezera moyo wawo wautumiki ndikuchepetsa ndalama zolipirira.Izi ndizothandiza makamaka pamagwiritsidwe apansi panthaka kapena m'mphepete mwa nyanja pomwe mapaipi amakumana ndi zovuta zachilengedwe.

Kutha kunyamula kwakukulu:

Khalidwe linanso lofunikira la ASTM A252 spiral welded steel chitoliro ndi mphamvu yake yabwino yonyamula katundu.Ukadaulo wowotcherera wa Spiral womwe umagwiritsidwa ntchito popanga umapangitsa kuti chitolirocho chikhale ndi mphamvu komanso kuti athe kupirira katundu wolemetsa.Kaya amagwiritsidwa ntchito pomanga mlatho, maziko a zomangamanga kapena mapaipi apansi panthaka, mapaipiwa amapereka umphumphu wapamwamba kwambiri, kuchepetsa chiopsezo cha kulephera ndikuonetsetsa kuti chitetezo cha nthawi yayitali cha ntchito zosiyanasiyana za zomangamanga.

Kukhazikika kwachilengedwe:

Munthawi yomwe chitetezo cha chilengedwe chili chodetsa nkhawa padziko lonse lapansi, kusankha zomangira zoyenera ndikofunikira.Spiral welded steel pipe ASTM A252 imagwirizana ndi machitidwe omanga okhazikika chifukwa cha kulimba kwake komanso kubwezeretsedwanso.Mapaipi amakhala ndi moyo wautali wautumiki ndipo amatha kusinthidwa mosavuta kumapeto kwa moyo wawo, kuchepetsa kufunika kochotsa zinthu zatsopano ndikuchepetsa zinyalala ndi mpweya.

Pomaliza:

Spiral welded steel chitoliro ASTM A252 yasintha makampani opanga mapaipi ndi mphamvu zake zapamwamba, kulimba komanso kutsika mtengo.Mapaipiwa amakumana kapena kupitilira miyezo yamakampani, kuwapanga kukhala chisankho choyamba m'mafakitale angapo.Mphamvu zake zabwino zonyamula katundu komanso kukana kwa dzimbiri zimatsimikizira chitukuko chokhazikika cha ntchito zomangamanga ndikuthandizira kupititsa patsogolo makampani apadziko lonse lapansi.Pogwiritsa ntchito mapaipiwa, ntchito zomanga zimatha kukulitsa luso, kuchepetsa ndalama ndikuwonetsetsa kudalirika kwa nthawi yayitali ndikutsata kukhazikika kwa chilengedwe.
