    Chimodzi mwazopindulitsa kwaA252 Gawo 3 Lachitsulo ndi mphamvu yapadera komanso kulimba. Mapaipi awa amapangidwa ndi chitsulo chapamwamba kwambiri ndipo amalimbana kwambiri ndi kutukuka, kuvala ndi kukhudzidwa. Izi zimawapangitsa kukhala abwino kugwiritsa ntchito mapaipi asodzi momwe angadziwitsidwe ndi zinthu zachilengedwe komanso katundu wolemera. Kuphatikiza apo mphamvu zawo ndi kukhazikika zimawapangitsa kukhala oyenera kuti agwiritsidwe ntchito pomanga mapaipi mapaimwa mafuta, chifukwa amayenera kupirira zovuta zapamwamba ndikusintha mikhalidwe ya chilengedwe.

    Njira ina yofunika kwambiri ya A252 Prigi 3 ndi kugwirizana kwake ndi mitundu yomangamanga. Mapaipi awa amatha kukhazikitsidwa pogwiritsa ntchito njira zachikulire zokumba kapena njira zopanda matchulidwe monga kubowola koyenda, chitoliro cha chitoliro kapena micro-turneling. Kusintha kumeneku kumalola kukhazikitsa koyenera komanso kokwera mtengo m'malo osiyanasiyana, kuphatikizapo malo akumatauni, komanso malo okhazikika.

    Ponseponse, A252 kalasi 3 yachitsulo imapereka zabwino zosiyanasiyana zomanga za Sewer ndi petroleum mapaipi. Mphamvu zawo, kulimba, kugwiritsa ntchito mosiyanasiyana komanso kugwiritsa ntchito mtengo kumawapangitsa kukhala abwino pofuna izi. Kaya limagwiritsidwa ntchito mu sewer kapena pomanga mapaipi a mafuta, mapaipi awa amapereka ntchito zodalirika komanso nthawi yayitali.
