Ubwino ndi Ntchito Zogwiritsa Ntchito Mapaipi Achitsulo (ASTM A252)

Yambitsitsani:

Mapaipi achitsulo ndi gawo lofunikira pamafakitale osiyanasiyana ndikuthandizira pakuyendetsa madzi, mpweya komanso ngakhale zida zolimba. Mtundu umodzi wofunikira wa chitoliro chomwe chakhala chotchuka kwambiri pakadutsa nthawi ndi chitoliro chachitsulo. Blog iyi imayang'ana mwakuya ndi mapulogalamu ndi mapulogalamu a spraft chitoliro chachitsulo, ndikuyang'ana mwapadera kwa Astm A252 Standard.

Zabwino zaChitoliro chowala ndi olima (ASTM A252):

1. Mphamvu ndi umphumphu:

Matumba owoneka bwino achitsulo ali ndi umphumphu wabwino kwambiri, ndikupanga kukhala koyenera kugwiritsa ntchito mphamvu zofunikira komanso kulimba. Miyezo ya Astm A2522 imatsimikizira kuti mapaipi awa, akuwapangitsa kukhala abwino polojekiti ofunikira.

2. Ubwino wowononga:

Poyerekeza ndi njira zina zopangidwa monga wosawoneka bwino kapena zazitali zazitali, mapaipi owoneka bwino amapereka yankho lokwera mtengo. Njira yotentha yomwe imagwiritsidwa ntchito popanga kupanga imawapangitsa kuti azitha kupezeka komanso yotsika mtengo, pamapeto pake kupindulitsa mafakitale ndi ogula.

3. Kusiyanitsa:

Chitoliro chowala ndi chosiyanasiyana ndipo chingagwiritsidwe ntchito m'mafakitale osiyanasiyana, kuphatikizapo mafuta ndi mpweya, kupezeka kwamadzi, zomangamanga ndi geotechnical. Mapulogalamu awo osiyanasiyana amawapangitsa kuti azisankha bwino polojekiti ambiri, mosasamala za kukula kwawo ndi zovuta zina.

Mapulogalamu a Spraft Splied Steel Pipe (ASTM A252):

1. Makampani a mafuta:

Makampani a mafuta ndi gasi amadalira kwambiriMapaipi owoneka bwinokunyamula katundu wa petroleum patali mtunda wautali. Mphamvu zawo, kukhazikika, komanso kukana kutentha kwambiri ndi zovuta zina zimapangitsa kuti iwo asankhe koyamba mafuta ndi gasi.

2. Makina a Madzi ndi Dongosolo la Chimbudzi:

M'madzi ndi makina owononga madzi, mapaipi owoneka bwino amagwiritsidwa ntchito popewa kuwonongedwa komanso kuchita mophweka. Kutha kunyamula ma voliyumu akuluakulu amadzi ndi kunyamula masoka, mapaipi awa ndikofunikira kuti azikhala ndi malo ofewetsa.

3.

Chitoliro chachitsulo chowoneka bwino ndichovuta kwambiri pantchito zomangamanga komanso zomangamanga monga milatho, misewu yayikulu, misewu ndi malo obisika. Mapaipi awa amatha kupirira katundu wolemera ndipo ndi oyenera othandizira ndi maziko mumitundu yonse yomanga.

4. Zingwe ndi Maziko:

Mapaipi owoneka bwino ozungulira potsatira miyezo ya Asthe a252 amagwiritsidwa ntchito kwambiri pakuthirira ndi maziko amalimbikitsa kukhazikika ndi mphamvu ya kapangidwe kake. Nthawi zambiri amagwiritsidwa ntchito popanga maziko okhazikitsidwa ndi nyumba, gulu la mafakitale komanso nsanja zam'madzi.

Pomaliza:

 Chitoliro chowalaamagwirizana ndi miyezo ya Asthe a252 ndipo amapereka maubwino ochulukirapo ndipo ali ndi ntchito zosiyanasiyana m'mafakitale osiyanasiyana. Mphamvu zawo, kugwiritsa ntchito mtengo wolemera ndi kusinthasintha kumapangitsa kuti chisankho choyambirira chikhale chovuta kuchokera ku mapaipi a mafuta ndi masitolo amadzi ndi ntchito zomanga. Monga ukadaulo ukupitilirabe, kufunikira kwake kwa mapaipi owoneka bwino owoneka bwino akukula, potero kuchititsa kuti chitukuko cha mafakitale ambiri komanso chomanga padziko lonse lapansi.
