720 mm× 87 mm Thick wall GB 8162 Grade 20 Seamless Steel Pipe Ultrasonic Test

Pa machubu achitsulo a 20# okhala ndi makulidwe a makoma mpaka 87mm, umphumphu wamkati ndi wofunika kwambiri, chifukwa ngakhale ming'alu yaying'ono ndi zinyalala zimatha kuwononga kwambiri umphumphu wawo ndi magwiridwe antchito awo, ndipo kuyesa kwa ultrasound kumatha kuzindikira bwino zolakwika izi.

Kuyesa kwa Ultrasonic, komwe kumatchedwanso UT, ndi njira yoyesera yosawononga yomwe imagwiritsa ntchito mawonekedwe a kuwunikira, kusinthasintha, ndi kuchepetsa mafunde a Ultrasonic pamene akufalikira kudzera muzinthu kuti azindikire zolakwika mkati mwa zinthuzo.

Pamene mafunde a ultrasound akumana ndi zolakwika mkati mwa zinthu monga ming'alu, zosakaniza kapena mabowo, mafunde owunikira adzapangidwa, ndipo malo, mawonekedwe ndi kukula kwa zolakwikazo zitha kudziwika polandira mafunde owunikirawa.

Kudzera mu kuyang'anitsitsa mosamala, zimaonetsetsa kuti chitoliro chonse chachitsulo chilibe zolakwika ndipo chikugwirizana mokwanira ndi miyezo ndi zofunikira za makasitomala.

Botop ndi kampani yodziwika bwino komanso yodalirika yopanga mapaipi achitsulo opangidwa ndi welded komanso yogulitsa mapaipi achitsulo osasemphana ku China, yomwe imakupatsani zinthu za mapaipi achitsulo okhala ndi khalidwe lodalirika komanso mtengo wopikisana. Tikulonjeza kuthandiza bungwe loyang'anira katundu wachitatu pazinthu zonse zomwe timagulitsa, ndipo tidzakonza zoyang'anira kuti ayang'anenso mapaipi achitsulo pamene mapaipi achitsulo aperekedwa kuti atsimikizirenso ubwino wa mapaipi achitsulo.

Zamkati Zokulitsidwa

GB/T 8162 ndi muyezo woperekedwa ndi China wamapaipi achitsulo opanda msokopa ntchito yomanga. 20# ndi mtundu wamba wa chitsulo cha kaboni chokhala ndi makhalidwe abwino a makina ndi kukonza, chomwe chimagwiritsidwa ntchito kwambiri popanga nyumba ndi nyumba zamakina.

Zofunikira pa kapangidwe ka mankhwala ndi kapangidwe ka makina a GB/T 8162 Giredi 20 ndi izi:
