Kampaniyo imagwirizana ndi filosofi ya "Khalani pamwamba pa njira yothetsera chitoliro", tidzapitirizabe kutumikira makasitomala am'mbuyomu komanso atsopano ochokera kunyumba ndi kunja kwathunthu. Kwa chitoliro cha carbon steel welded kapena chopanda msoko chomwe chimatsatira muyezo wa ASTM A53, tili ndi zaka zopitilira 30 zogula ndikugulitsa, zomwe zingatsimikizire kuti tili ndi luso loonetsetsa kuti mapaipi onse ndi apamwamba kwambiri.
Pa chitoliro chopanda msoko, pali chitoliro chabodza chopanda msoko, chomwe ndi makina otsika kuposa chitoliro chopanda msoko, chifukwa amapangidwa kuchokera ku chitoliro cha ERW, pambuyo pa ndondomeko, mzere wowotcherera wasinthidwa kukhala wosawoneka. Chitoliro chokoma ichi sichingathe kupirira kuthamanga kwambiri, ndi mphamvu zolimba, kupsinjika kwamkati zonse sizingakwaniritse zofunikira za chitoliro chopanda msoko. Ngati musakaniza chitoliro chamtundu uwu, chonde dziwani kuti chitoliro cha ERW chimapangidwa kuchokera kuzitsulo zazitsulo, kotero chimakhala ndi makulidwe a khoma; Chitoliro chopanda msoko amapangidwa kuchokera ku kapamwamba kozungulira, koboola pakati pa kapamwamba kuti apange mipope, kotero makulidwe a khoma si yunifolomu. Ndipo mzere wowotcherera wa chitoliro chabodza chopanda msoko ukadalipo, ngati muyang'ana chitoliro chamkati mosamala, mutha kuchipeza.
Amagwiritsidwa ntchito makamaka pazigawo zamphamvu ndi zokakamiza, komanso pazolinga zonse za nthunzi, madzi, gasi ndi mapaipi amlengalenga.
