Zvakadaro, nzira yekuunganidza sampuli yekuongororwa kwemuchina ichaenderana neJIS G 0404 Clause 7.6 (Specimen collection conditions and specimens), Rudzi A.
Pipe testers ichaita bvunzo zvinoenderana neJIS Z 2241 uye kusimba kwesimba, goho simba, uye kureba zvichaenderana neTafura 3.
Zvisinei, kune machubhu asingasviki 8 mm gobvu, kureba kunofanira kuenderana neTafura 4 yekuedza kuyedza kushandisa Nhamba 12 kana Nhamba 5.
Flattening Test
Tembiricha yekuyedza inofanirwa kunge iri tembiricha yekamuri (5 ~ 35 ℃), muenzaniso unoiswa pakati pemahwendefa maviri akafuratira uye akatsikirirwa kusvika chinhambwe H pakati pemahwendefa chiri pasi pemutengo wakatarwa, kana saizi yacho yapepetwa, tarisa kana paine mutswe. pamusoro pesimbi pombi sampuli block.
Kana H=2/3D, tarisa weld kune yakatsemuka.
Kana H=1/3D, tarisa kune makatsemuka mune zvimwe kunze kweweld seam.
Seamless simbi pombi inogona kusunungurwa kubva pakuyedzwa kwe flattening, asi kushanda kwepombi kunofanirwa kuenderana nezvinodiwa.
Bending Test
Inoshanda kune mapaipi ane dhayamita yekunze ≤ 40A (48.6mm).
Muenzaniso haufanirwe kutsemuka kana wakakotama pa 90 ° neradius yemukati ka6 pane dhayamita rekunze.
Mutengi anogona kudoma kona yekukombama ye180 uye/kana nharaunda yemukati yeka 4 dhayamita rekunze kwepombi.
Nekupikisa welded pombi, iyo weld seam ichawanikwa inosvika 90 ° kubva kumucheto kwebend.
Muedzo weHydraulic kana Muedzo usingaparadzi
Mapombi ese anofanirwa kuyedzwa hydraulically kana kuti isiri-inoparadza.
Zvisinei, kune mapaipi machena, izvi zvinowanzoitwa zvisati zvaita galvanizing.
Hydrotesting kana kusaparadza kuyedzwa inzira yakakosha yekupombi yemhando yekudzora kuve nechokwadi chekuchengetedza uye kuvimbika kwepombi panguva yekuisa uye kushandiswa.
Hydrostatic Test
Isa yakakwira-kupfuura-inotsanangurwa hydraulic test pressure kune pombi woibata kweinenge 5 seconds kuti uone kana pombi ichikwanisa kumira kumanikidza uye kana kuvuza kuchiitika.
