Munthawi ino yomwe ikukula mwachangu m'makampani omanga ndi zomangamanga, njira zodalirika komanso zolimba zopezera mapaipi zakhala chinsinsi cha kupambana kwa polojekitiyi. Monga wopanga wamkulu wa mapaipi achitsulo chozungulira ndi zinthu zokutira mapaipi ku China, Cangzhou Spiral Steel Pipes Group Co., Ltd. yayambitsaChitoliro cha Mzere cha X70 SSAW, zomwe zikufotokoza mbadwo watsopano wa miyezo ya Line Pipe ndi magwiridwe ake abwino kwambiri.
Chitoliro cha X70 ndi chinthu chachikulu chomwe chimachokera ku chitsulo chapamwamba kwambiri, chomwe chili ndi mphamvu yoposa 485 MPa, chomwe chimatsatira miyezo yokhwima monga API 5L ndi GB/T 9711. Chimaphatikiza mphamvu yayikulu ndi kulimba kwabwino kwambiri ndipo chimatha kuthana ndi mavuto ambiri monga kuthamanga kwambiri ndi dzimbiri m'malo oyika pansi pa nthaka. Chimagwiritsa ntchito njira yolumikizira ya advanced spiral submerged arc welding (SSAW), pomwe chingwe chachitsulo chimapindidwa mozungulira kenako chimalumikizidwa. Kupsinjika kwa weld kumagawidwa mofanana, zomwe zimapatsa payipi mphamvu yayikulu yokakamiza komanso kukana dzimbiri, makamaka yoyenera mapaipi a gasi pansi pa nthaka, uinjiniya wa maziko, ndi zina zofunika kwambiri. Mafotokozedwe azinthuzo amayambira pa 219mm mpaka 3500mm, okhala ndi kutalika kwa single mpaka mamita 35, kukwaniritsa bwino zosowa za zomangamanga zazikulu zosiyanasiyana komanso ntchito zapadera.
Kutengera ndi kusonkhanitsa kwaukadaulo kuyambira pomwe idakhazikitsidwa mu 1993, Cangzhou Spiral Steel Pipes Group Co., Ltd. ndi kampani yamphamvu: fakitale yake ili ndi malo okwana masikweya mita 350,000, ndi katundu wonse wa yuan 680 miliyoni, ndipo ili ndi antchito 680. Mphamvu yake yopangira mapaipi achitsulo ozungulira pachaka imafika matani 400,000, ndipo phindu lake pachaka ndi yuan 1.8 biliyoni. Kampaniyo imayang'anira mosamala njira yonse kuyambira kusankha zinthu zopangira mpaka kuwunika zinthu, kuchita mayeso angapo monga kuyesa kwa x-ray ndi kuzindikira zolakwika za ultrasound kuti zitsimikizire kuti ntchitoyo ndi yokhalitsa komanso magwiridwe antchito okhazikika. Monga yankho la Line Pipe lomwe limaphatikiza khalidwe ndi kusinthasintha, X70 SSAWChitoliro cha MzereSikuti imangoyenera kunyamula gasi ndi madzi pansi pa nthaka, komanso imagwira ntchito bwino poika mapaipi akutali komanso potumiza madzi m'mafakitale, zomwe zimapangitsa kuti ikhale chisankho chodalirika pamapulojekiti apadziko lonse lapansi.
