A252 Chitsogozo Chokwanira Chopita ku Sitandade 2 Chitoliro Chachitsulo: Choyenera Pamapulojekiti Awiri Omwe Amalowa Arc Welded Sewer Line
Phunzirani za Pipe yachitsulo ya A252 Grade 2:
A252 GRADE 2 Chitoliro chachitsulondi chitoliro cha chitsulo cha kaboni chomwe chimapangidwira kuti chigwiritsidwe ntchito pakupopera kwapaipi ndi ntchito zamapangidwe.Amapangidwa motsatira miyezo ya ASTM (American Society for Testing and Equipment), kuwonetsetsa kuti miyezo yapamwamba komanso yolondola kwambiri.Matchulidwe a GRADE 2 akuwonetsa kuti chitoliro chachitsulo chimapangidwa pogwiritsa ntchito kuwotcherera arc pansi pamadzi kapena njira zowotcherera zopanda msoko.
Kufunika kowotcherera pawiri pansi pamadzi:
Kuwotcherera kwa arc komizidwa kawiri, yomwe imadziwikanso kuti DSAW, ndi njira yowotcherera yomwe imagwiritsidwa ntchito polumikizana ndi zigawo za A252 GRADE 2 chitoliro chachitsulo.DSAW imapereka maubwino angapo kuposa njira zina zowotcherera, kuphatikiza kukhulupirika kwa weld, kuthamanga kwambiri, kupotoza pang'ono, komanso kuwongolera kwabwino kwa kutentha.Zimatsimikizira mgwirizano wamphamvu pakati pa mapaipi, kuwapangitsa kuti asavutike kwambiri ndi kutayikira, dzimbiri komanso kuwonongeka kwamapangidwe.

Chifukwa chiyani mugwiritse ntchito chitoliro chachitsulo cha A252 Grade 2 pama projekiti a zimbudzi?
1. MPHAMVU ZABWINO NDI KUKHALA KWABWINO: A252 GRADE 2 chitoliro chachitsulo chimakhala ndi mphamvu zowonongeka, zomwe zimapangitsa kuti zisagwirizane ndi zovuta zakunja ndi zovuta.Kukhalitsa kwawo kumatsimikizira moyo wautali wautumiki, kuchepetsa kufunika kosinthidwa pafupipafupi kapena kukonzanso.
2. Kukaniza kwa Corrosion: Chitoliro chachitsulo cha A252 GRADE 2 chapangidwa kuti chizitha kupirira mikhalidwe yovuta ya pansi pa nthaka, kuphatikizapo kukhudzana ndi zimbudzi, mankhwala ndi chinyezi, popanda kuwononga kapena kuwononga.Mbali imeneyi imawonjezera kwambiri moyo wautumiki wa mipope ya zimbudzi.
3. Zotsika mtengo: A252 Grade 2 chitsulo chitoliro amapereka njira yotsika mtengo yopangira mapaipi a sewero.Zofunikira zawo zocheperako komanso moyo wautali zitha kupulumutsa ma municipalities ndi makontrakitala a polojekiti ndalama zambiri pakapita nthawi.
Kugwiritsa ntchito chitoliro chachitsulo cha A252 giredi 2 mu engineering ya sewer:
Chitoliro chachitsulo cha A252 GRADE 2 chimagwiritsidwa ntchito kwambiri m'mapulojekiti osiyanasiyana opangira zimbudzi, kuphatikiza:
1. Dongosolo la zinyalala zamatauni: Mapaipi achitsulo a A252 Grade 2 amagwiritsidwa ntchito kwambiri pomanga mapaipi amadzi otayira am'matauni kuti ayendetse bwino madzi oyipa kuchokera ku malo okhala ndi malonda kupita kumalo opangira mankhwala.
2. Industrial Sewerage System: Mafakitale amafunikira makina athanzi amphamvu kuti azitha kutulutsa madzi oyipa kuchokera kumagawo opanga zinthu ndi zina.Chitoliro chachitsulo cha A252 GRADE 2 chimapereka mphamvu yofunikira komanso kulimba kwa mtundu uwu wa ntchito ya chitoliro chamadzi otayira m'mafakitale.
Pomaliza:
Zikafikachingwe cha sewerozomangamanga, A252 GRADE 2 chitsulo chitoliro pamodzi ndi luso kuwotcherera DSAW amapereka mphamvu zosayerekezeka, kulimba ndi ntchito wonse.Kukana kwake kwapadera kwa dzimbiri, kulimba kwamphamvu kwambiri komanso kutsika mtengo kumapangitsa kuti ikhale yabwino pama projekiti osiyanasiyana opangira zimbudzi.Potengera zida zapamwambazi ndi njira zowotcherera, mizinda imatha kukulitsa nthawi yayitali komanso magwiridwe antchito a ngalande zawo, kuchepetsa mtengo wokonza ndikuwonetsetsa kuti pamakhala malo aukhondo, athanzi kwa aliyense.
