Izi ndizofunikira makamaka pamapulojekiti okhudza ntchito yomanga mulu, chifukwa kukhulupirika ndi kulimba kwa zida zomwe zimagwiritsidwa ntchito zimakhudza mwachindunji kupambana kapena kulephera kwa nyumbayo.
Cangzhou Spiral Steel Pipe Group Co., Ltd. ili pakatikati pa mzinda wa Cangzhou, m'chigawo cha Hebei. Iwo wakhala kutsogolera welded chitoliro wopanga kuyambira kukhazikitsidwa kwake mu 1993. Kampani chimakwirira kudera la mamita lalikulu 350,000, ali chuma okwana RMB 680 miliyoni, ndipo pafupifupi 680 antchito aluso ndi akatswiri. Kudziwa zambiri komanso zomangamanga zolimba zimapangitsa kampaniyo kupanga mapaipi apamwamba kwambiri a ASTM A252 omwe amakwaniritsa zofunikira pamakampani omanga.
Mafotokozedwe a ASTM A252 amakwirira milu yachitsulo yapakhoma yomwe ili ndi mawonekedwe a cylindrical. Milu iyi idapangidwa kuti igwiritsidwe ntchito ngati mamembala onyamula katundu osatha kapena ngati milu ya milu ya konkriti. Ntchito yapawiriyi ndi yofunika kwambiri kuti zitsimikizire kuti maziko a mazikowo akusungidwa kwa nthawi yaitali. M'malo omwe nthaka ingakhale yovutirapo, kugwiritsa ntchito milu ya ASTM A252 tubular ndikopindulitsa kwambiri chifukwa kumapereka mphamvu ndi kukhazikika komwe kumafunikira kuthandizira katundu wolemetsa.

Kukula kwa Chitoliro cha Astm A252milu ili ndi zabwino zotsatirazi:
Chopangidwa ndi chitsulo champhamvu kwambiri, chimakhala ndi ntchito yabwino yonyamula katundu
Chithandizo cha akatswiri odana ndi dzimbiri, choyenera m'malo ovuta monga chinyontho komanso mikhalidwe ya saline-alkali
Itha kugwiritsidwa ntchito ngati chigawo chokhazikika chonyamula katundu kapena chipolopolo cha mulu wa konkriti
Chepetsani kuchuluka kwa zolumikizira pamalopo ndikuwonjezera mphamvu zamapangidwe
Ubwino umodzi waukulu wogwiritsa ntchito mapaipi a ASTM A252 pochulutsa mapulogalamu ndikutha kupirira zovuta zachilengedwe. Chitsulo chomwe chimagwiritsidwa ntchito m'mapaipiwa chimagwiritsidwa ntchito kuti zisawonongeke, kuonetsetsa kuti moyo wawo utalikirapo komanso kuchepetsa ndalama zothandizira nthawi yayitali. Izi ndizofunikira makamaka m'malo omwe mapaipi amatha kukhala ndi dothi lonyowa kapena lolimba.
Kuphatikiza apo, kupanga kwa Cangzhou Spiral Steel Pipe Group Co., Ltd. Kudzipereka kumeneku ku khalidwe sikungowonjezera ntchito ya chitoliro, komanso kumapangitsanso chidaliro cha makontrakitala ndi mainjiniya omwe amadalira zipangizozi pa ntchito zawo.
Zonsezi, chitoliro cha ASTM A252 ndichinthu chofunikira kwambiri pantchito yomanga, makamaka pakuchulukira ntchito. Ndi ukatswiri ndi chuma cha Cangzhou Spiral Steel Pipe Group Co., Ltd., makasitomala atha kutsimikiziridwa kuti alandila mapaipi apamwamba kwambiri omwe amakwaniritsa zosowa zawo zenizeni. Pomwe kufunikira kwa zida zomangira zolimba komanso zodalirika kukukulirakulira, chitoliro cha ASTM A252 mosakayikira chidzatenga gawo lofunikira pakukonza chitukuko chamtsogolo. Kaya mukuchita nawo ntchito yomanga yayikulu kapena yaying'ono, lingalirani zaubwino wophatikizira chitoliro cha ASTM A252 mu yankho lanu la maziko.
