Kwa 20 # machubu achitsulo okhala ndi makulidwe a khoma mpaka 87mm, kukhulupirika kwamkati ndikofunikira kwambiri, chifukwa ngakhale ming'alu yaying'ono ndi zonyansa zimatha kusokoneza kukhulupirika ndi magwiridwe antchito, ndipo kuyezetsa akupanga kumatha kuzindikira zolakwika zomwe zingachitike.
Kuyesa kwa Ultrasonic, komwe kumatchedwanso UT, ndi njira yoyesera yosawononga yomwe imagwiritsa ntchito mawonekedwe owunikira, kubweza, komanso kutsitsa mafunde akupanga pamene akufalikira kudzera muzinthu kuti azindikire zolakwika zomwe zili mkati mwazinthuzo.
Pamene mafunde akupanga akukumana ndi zolakwika mkati mwa zinthu monga ming'alu, inclusions kapena mabowo, mafunde owonetseredwa adzapangidwa, ndipo malo, mawonekedwe ndi kukula kwa zolakwikazo zikhoza kutsimikiziridwa ndi kulandira mafunde owonetserawa.
Kupyolera mu kuyang'anitsitsa bwino, zimatsimikizira kuti chitoliro chonse chachitsulo sichikhala ndi chilema ndipo chimagwirizana kwathunthu ndi miyezo ndi zofuna za makasitomala.
Botop ndi katswiri komanso wodalirika wopanga mapaipi azitsulo a Welded Steel Pipe ndi Seamless Steel Pipe stockist ku China, akukupatsirani zida zapaipi zachitsulo zodalirika komanso mtengo wopikisana. Timalonjeza kuti tithandizira bungwe lachitatu loyang'anira katundu wazinthu zonse zomwe timagulitsa, ndipo tidzakonza oyang'anira kuti ayang'anenso mapaipi achitsulo pamene gulu lililonse lazitsulo lazitsulo likuperekedwa kuti zitsimikizire kuti mipope yachitsulo imakhala yabwino.
GB/T 8162 ndi muyezo woperekedwa ndi Chinamapaipi opanda zitsuloZolinga zamamangidwe. 20 # ndi wamba mpweya zitsulo kalasi ndi katundu wabwino makina ndi processing, chimagwiritsidwa ntchito pomanga nyumba ndi zomangamanga makina.
GB/T 8162 Giredi 20 kapangidwe ka mankhwala ndi zofunikira zamakina zamakina ndi izi:
