Pakadali pano, ziphuphu zambiri zogwiritsidwa ntchito ku China ndi mapaipi owala Q195, Q215, Q235, ndi ma canbon ena wamba amkaka. Komabe, kupendekera mapaipi achitsulo m'maiko omwe adatukuka kumene kumagwiritsa ntchito mapaipi a alloy yachitsulo. Poyerekeza ndi mapaipi achitsulo wamba, mphamvu zokolola zotsika zitsulo zotsika zitha kuwonjezeka ndi 46%, kulemera kumachepetsedwa ndi 20% mpaka 38%, ndipo moyo wa ntchito umawonjezeka ndi 25%. Makampani omanga nyumbayo pabanja nawonso amafunikanso kuwongola mapaipi owoneka bwino kwambiri, koma si ambiri opanga. Akatswiri amasanthula maubwino atatu ogwiritsa ntchito zitsulo zotsika zotsika kuti zisinthe mapaipi achitsulo;
Choyamba, imatha kuchepetsa ndalama zomanga zomangira makampani omanga. Mtengo uliwonse umakhala ndi chitsulo chotsika mtengo ndi 25% kuposa momwe umakhalira wachitsulo wamba, koma mtengo pa mita ungatsike 13% yotsika. Nthawi yomweyo, chifukwa cha zopepuka za mapaipi otsika kwambiri, ndalama zomwe ndalama zimasunga ndizofanananso.
Chachiwiri, zitsulo zambiri zitha kupulumutsidwa. Kugwiritsa ntchito φ48mm × 2.5mm yotsika-chitsulo chaching'ono kuti isinthe ma φ48mm × 3.5mm ziphuphu zazitsulo za mpweya zitha kupulumutsa ma kilogalamu 270 a chitsulo chilichonse. Kuphatikiza apo, mapaipi otsika kwambiri amakhala ndi vuto labwino komanso moyo wautali wautumiki, womwe ndi wopindulitsa kupulumutsa zitsulo ndikusintha phindu lachuma.
Chachitatu, chifukwa cha zopepuka ndi mphamvu zabwino za chitoliro chachitsulo chotsika, sichingachepetse mphamvu za ogwira ntchito komanso kusinthasintha kwa msonkhano komanso kupanga malo abwino opangira chitetezo chomanga. Chifukwa chake, kusinthana chitoliro chaching'ono cha kaboni kaboni kaboni chotsika ndi chitsulo chotsika chitoliro chili ndi phindu la chuma komanso chikhalidwe. Nthawi yomweyo, zambiri zomwe zimachitika ndi zida zokweza ndikukula ndikukula mowongolera zopepuka komanso zolimbitsa thupi, kukhazikitsa, msonkhano, ndi ntchito zambiri. Njira yoyeserera imayamba kukhala ndi msonkhano pang'onopang'ono, kuchepetsa kapena kuthetsa othamanga, ma balts, ndi mbali zina; Zipangizozi zidzatengera pang'onopang'ono, aluminiyamu a almoy, ndi zinthu zina zomwe zimakhalanso ndi mafelemu owoneka bwino, etc. Chingwe chokutira chomwe chingakhazikike mwachangu, chosasunthika, komanso chokhazikika chonse.
Machubu owumbika amagwiritsidwa ntchito kwambiri chifukwa chothandizira. Monga dziko lopanga zitsulo zopangira, padakali njira yayitali kuti ipitirize kusintha mitundu yamitundu yomwe ikukhudzana ndi njira zomwe anthu akumana nazo.
