Ubwino ndi Ntchito za Mapaipi a Zitsulo Ozungulira (ASTM A252)

Yambitsani:

Mapaipi achitsulo ndi gawo lofunika kwambiri m'mafakitale osiyanasiyana ndipo amathandiza kunyamula madzi, mpweya, ngakhale zinthu zolimba. Mtundu umodzi wofunika kwambiri wa chitoliro chachitsulo chomwe chakhala chotchuka kwambiri pakapita nthawi ndi chitoliro chachitsulo cholumikizidwa ndi spiral welded. Blog iyi ifotokoza mozama za ubwino ndi ntchito za chitoliro chachitsulo cholumikizidwa ndi spiral welded, makamaka pa muyezo wa ASTM A252.

Ubwino wachitoliro chozungulira cholumikizidwa (ASTM A252):

1. Mphamvu ndi umphumphu wa kapangidwe kake:

Chitoliro chachitsulo cholumikizidwa ndi waya chili ndi kapangidwe kabwino kwambiri, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito chomwe chimafuna mphamvu zambiri komanso kulimba. Miyezo ya ASTM A252 imatsimikizira ubwino ndi mphamvu za mapaipi awa, zomwe zimapangitsa kuti akhale abwino kwambiri pa ntchito zofunika kwambiri.

2. Kugwiritsa ntchito bwino ndalama:

Poyerekeza ndi njira zina zopangira mapaipi monga kuwotcherera kopanda msoko kapena kotalika, mapaipi achitsulo olumikizidwa mozungulira amapereka njira yotsika mtengo. Njira yowotcherera yomwe imagwiritsidwa ntchito popanga zinthu imapangitsa kuti zikhale zosavuta kuzipeza komanso zotsika mtengo, zomwe pamapeto pake zimapindulitsa makampani ndi ogula.

3. Kusinthasintha:

Chitoliro cholumikizidwa ndi spiral chimagwiritsidwa ntchito m'njira zosiyanasiyana ndipo chingagwiritsidwe ntchito m'mafakitale osiyanasiyana, kuphatikizapo mafuta ndi gasi, madzi, zomangamanga ndi uinjiniya wa geotechnical. Kugwiritsa ntchito kwawo kosiyanasiyana kumapangitsa kuti zikhale zosangalatsa kwambiri pamapulojekiti ambiri, mosasamala kanthu za kukula ndi zovuta zake.

Kugwiritsa ntchito chitoliro chachitsulo cholumikizidwa mozungulira (ASTM A252):

1. Makampani Ogulitsa Mafuta ndi Gasi:

Makampani opanga mafuta ndi gasi amadalira kwambirimapaipi achitsulo ozungulira olumikizidwakunyamula zinthu zamafuta pa mtunda wautali. Mphamvu zawo, kulimba kwawo, komanso kukana kutentha kwambiri ndi kupsinjika zimapangitsa kuti zikhale chisankho choyamba cha mapaipi amafuta ndi gasi.

2. Njira yopezera madzi ndi zimbudzi:

Mu madzi ndi madzi otayira, mapaipi achitsulo olumikizidwa ndi spiral amagwiritsidwa ntchito kwambiri chifukwa amatha kupirira dzimbiri komanso kugwira ntchito moyenera. Popeza amatha kunyamula madzi ambiri komanso kunyamula zinyalala moyenera, mapaipi awa ndi ofunikira kwambiri pakusunga zomangamanga zonse.

3. Kumanga zomangamanga:

Chitoliro chachitsulo cholumikizidwa ndi waya ndi chofunikira kwambiri pa zomangamanga ndi ntchito zomanga monga milatho, misewu ikuluikulu, ngalande ndi zinthu zapansi panthaka. Mapaipi awa amatha kupirira katundu wolemera ndipo ndi oyenera kugwiritsa ntchito nyumba zothandizira ndi maziko amitundu yonse ya ntchito zomanga.

4. Ntchito zomangira ndi maziko:

Mapaipi achitsulo olumikizidwa mozungulira omwe akutsatira miyezo ya ASTM A252 amagwiritsidwa ntchito kwambiri pomanga ndi kuyika maziko kuti atsimikizire kukhazikika ndi kulimba kwa nyumbayo. Nthawi zambiri amagwiritsidwa ntchito popanga maziko olimba a nyumba, mafakitale komanso nsanja zakunja kwa nyanja.

Pomaliza:

 Chitoliro chozungulira cholumikizidwaikutsatira miyezo ya ASTM A252 ndipo imapereka zabwino zambiri ndipo imagwiritsa ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Mphamvu zawo, kugwiritsa ntchito bwino ndalama komanso kusinthasintha kwawo zimapangitsa kuti ikhale chisankho choyamba pa ntchito zofunika kuyambira mapaipi amafuta ndi gasi mpaka machitidwe amadzi ndi mapulojekiti omanga. Pamene ukadaulo ukupitilira kukula, kufunika ndi kufunikira kwa mapaipi achitsulo olumikizidwa mozungulira kukuyembekezeka kukula, motero kungathandize pakukula kwa mapulojekiti ambiri a mafakitale ndi zomangamanga padziko lonse lapansi.
