Itandukaniro riri hagati ya Astm A53 na A252 ni irihe?

Umuyoboro wa ASTM A252 ni iki?

ASTM A252 ni amabwiriza yemewe yashyizweho n'Umuryango w'Abanyamerika wita ku Bipimo n'Ibikoresho (ASTM), by'umwihariko ku miyoboro y'icyuma ikoreshwa mu gutunganya imigozi no gushyigikira imiterere y'inyubako. Iri hame rigena neza imiterere y'imiti, imiterere ya mekanike, ubushobozi bwo kwihanganira ingano n'uburyo bwo gupima imiyoboro y'icyuma, rigatuma imiterere yayo ikomera, iramba kandi ikagira ubushobozi bwo gutwara imizigo. Ni amahitamo meza ku mishinga y'ifatizo nka amagorofa, inyubako ndende n'ibyambu.

Ingano z'umuyoboro wa Astm A252ingano n'ibipimo

Imiyoboro ya ASTM A252 igabanyijemo ibyiciro bitatu hakurikijwe imbaraga zisabwa: GR 1, GR 2, na GR 3, muri byo GR 3 ifite imbaraga nyinshi. Ingano yayo irahindagurika kandi ishobora guhaza ibisabwa bitandukanye by’ubuhanga.

Umurambararo wo hanze (OD): Kuva kuri santimetero 6 kugeza kuri santimetero 60, ndetse n'ingano nini zishobora gukorwa.

Ubunini bw'urukuta (WT): Ubusanzwe hagati ya santimetero 0.188 na santimetero 0.500, kandi bushobora guhindurwa hakurikijwe ibisabwa kugira ngo habeho ubwisanzure bwo gukanda no kunama.

Uburebure: Uburebure busanzwe ni metero 20 cyangwa metero 40. Umusaruro wihariye nawo ushyigikiwe hakurikijwe ibisabwa n'umushinga.

Ubu bwoko bwinshi bw'ingano butuma injeniyeri zishobora guhitamo ibikoresho bihendutse cyane ku mishinga runaka.

Umuyoboro wa ASTM A252 ukoreshwa mu bintu bitandukanye, harimo:

1. Guteranya imiyoboro: Iyi miyoboro ikunze gukoreshwa nk'ibirundo by'ubutaka mu mishinga y'ubwubatsi kugira ngo ikomeze kandi ishyigikire inyubako.
2. Ibiraro: Uburemere n'ubudahangarwa bw'umuyoboro wa ASTM A252 bituma uba amahitamo meza yo kubaka ibiraro, aho ushobora kwihanganira imitwaro iremereye n'ibidukikije.
3. Imiterere y'inyanja: Kuba iyi miyoboro irwanya ingese bituma ikoreshwa mu bikorwa byo mu nyanja nko ku cyambu no ku nkombe.
4. Peteroli na Gazi: Kubera ko yubakishijwe neza, umuyoboro wa ASTM A252 ukoreshwa no mu nganda za peteroli na gaze mu gutwara amazi n'imyuka.

Muri make

Mu magambo make, umuyoboro wa ASTM A252 ni ingenzi cyane mu bikorwa bitandukanye by’ubwubatsi, bigatuma habaho kwizerwa no gukomera. Uru ruganda ruri i Cangzhou, mu Ntara ya Hebei, ni ikigo gikomeye mu gukora ubwo bwoko bw’imiyoboro, giharanira ko ibicuruzwa byacyo byujuje ibisabwa by’ubuziranenge. Kubera ko cyihaye intego yo kuba indashyikirwa kandi cyibanda ku guhanga udushya, ikigo gikomeje kugira uruhare runini mu bwubatsi n’ibikorwaremezo. Waba ufite uruhare mu mushinga munini w’ubwubatsi cyangwa ukeneye igisubizo cyizewe cyo gukoresha imiyoboro, umuyoboro wa ASTM A252 ni amahitamo meza cyane ku byo ukeneye.
