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

Ku miyoboro y'icyuma ifite ubugari bwa 20# ifite ubugari bw'inkuta bugera kuri mm 87, ubuziranenge bw'imbere ni ingenzi cyane, kuko n'imiyoboro mito n'imyanda bishobora kwangiza cyane imiterere n'imikorere yayo, kandi ibizamini bya ultrasound bishobora kugaragaza neza ibyo bibazo bishobora kubaho.

Gupima hakoreshejwe ikoranabuhanga rya Ultrasonic, rizwi kandi nka UT, ni uburyo bwo gupima budasenya bukoresha imiterere yo kugarura, kugarura no kugabanya imiraba ya Ultrasonic mu gihe ikwirakwira mu bikoresho kugira ngo hamenyekane inenge ziri mu bikoresho.

Iyo umuraba wa ultrasound uhuye n'ibisesenguzi mu bikoresho nk'imiturire, ibintu bivanze cyangwa imyobo, imiraba yagaragaye izavuka, kandi aho iherereye, imiterere n'ingano by'ibisesenguzi bishobora kumenyekana binyuze mu kwakira iyo miraba yagaragaye.

Binyuze mu igenzura ryimbitse, bigenzura ko umuyoboro wose w'icyuma udafite inenge kandi ko wujuje ibisabwa n'abakiriya.

Botop ni uruganda rw’imiyoboro y’icyuma rwabigize umwuga kandi rwizewe kandi rukora imiyoboro y’icyuma idafite umugozi mu Bushinwa, ruguha ibicuruzwa by’imiyoboro y’icyuma bifite ubuziranenge bwizewe kandi igiciro cyiza. Twizeza gushyigikira ikigo cy’ubugenzuzi ku bicuruzwa byose tugurisha, kandi tuzategura abagenzuzi kongera kugenzura imiyoboro y’icyuma igihe buri gice cy’imiyoboro y’icyuma kizagezwa kugira ngo twongere tumenye neza ubuziranenge bw’imiyoboro y’icyuma.

Ibikubiye mu byaguwe

GB/T 8162 ni ibipimo ngenderwaho byatanzwe n'Ubushinwa kuriimiyoboro y'icyuma idakora nezaku bw'inyubako. 20# ni urwego rusanzwe rw'icyuma cya karuboni gifite ubushobozi bwiza bwo gutunganya no gutunganya, gikoreshwa cyane mu nyubako n'inyubako za karuboni.

Ibisabwa ku miterere ya chimique ya GB/T 8162 yo mu cyiciro cya 20 n'imiterere ya mekanike ni ibi bikurikira:

Ibikoresho bya GB/T 8162 by'icyiciro cya 20 bya shimi:

Igipimo cy'icyuma	Imiterere y'ibinyabutabire, muri % by'uburemere
Igipimo cy'icyuma	C	Si	Mn	P	S	Cr	Ni	Cu
20	0.17 - 0.23	0.17 - 0.37	0.35 - 0.65	0.035 ntarengwa	0.035 ntarengwa	Ibipimo ntarengwa bya 0.25	Ibipimo ntarengwa bya 0.30	Ibipimo ntarengwa bya 0.25

Imiterere ya GB/T 8162 y'icyiciro cya 20:

Igipimo cy'icyuma	Imbaraga zo gukurura R_m MPa	Imbaraga zo gutanga umusaruro R_eL MPa			Uburebure A %
		Ingano y'umurambararo S
		≤16 mm	＞16 mm ≤30 mm	＞mm 30
20	≥410	245	235	225	20

Umuyoboro w'icyuma utagira umushongi wa GB 8162 wo mu cyiciro cya 20

Igihe cyo kohereza: 15 Ukwakira 2024

Ikizamini cya Ultrasonic cy'umuyoboro w'icyuma udafite umushongi wa 720 mm × 87 mm
