Mu bwubatsi n’ubwubatsi, guhitamo ibikoresho nibyingenzi kugirango habeho ubusugire no kuramba kurwego. Ikintu kimwe cyubahwa cyane mu nganda ni umuyoboro wa ASTM A252. Ibisobanuro bikubiyemo silindrike, nominal urukuta rw'ibyuma birinda ibirundo, nibyingenzi mubikorwa bitandukanye, cyane cyane mubuhanga bwububiko. Muri iyi blog, tuzahita twibira mubisobanuro byingenzi nibisabwa byerekana ingano ya ASTM A252 mugihe tugaragaza ubushobozi bwuruganda rukomeye ruherereye i Cangzhou, Intara ya Hebei.
Ibyingenzi byingenzi bya ASTM A252
ASTM A252 nigisobanuro gisanzwe cyerekana ibisabwa kubirundo byicyuma gisudira kandi kidafite kashe. Iyi miyoboro yagenewe gukoreshwa nkabanyamuryango bahoraho bitwaje imitwaro cyangwa nkibishishwa byo guterera-ibirundo bya beto. Ibyingenzi byingenzi bya ASTM A252 birimo:
1.Icyiciro cyibikoresho: Ibisobanuro birimo ibyiciro bitatu byibyuma: Icyiciro cya 1, Icyiciro cya 2, nicyiciro cya 3. Buri cyiciro gifite imbaraga zinyuranye zisabwa, hamwe nicyiciro cya 3 gifite imbaraga nyinshi zumusaruro kandi birakwiriye kubisabwa cyane.
2. Ingano: ASTM A252 imiyoboro iraboneka muburyo butandukanye bwurukuta rwizina, bituma habaho guhinduka mugushushanya no kubishyira mubikorwa. Iyi miyoboro iraboneka muri diametre kuva kuri santimetero 6 kugeza kuri santimetero 60 kugirango zuzuze ibisabwa bitandukanye byumushinga.
3. Amahitamo yo gusudira kandi adafite kashe:Umuyoboro wa ASTM A252Irashobora kubyara gusudira cyangwa kudasubirwaho, gutanga amahitamo ukurikije ibikenewe byumushinga wawe. Umuyoboro usudira muri rusange urahenze cyane, mugihe umuyoboro udafite imbaraga utanga imbaraga nukuri.
4. Kurwanya ruswa: Ukurikije porogaramu, imiyoboro ya ASTM A252 irashobora gutwikirwa cyangwa kuvurwa kugirango irusheho kwangirika kwangirika, bigatuma ikoreshwa igihe kirekire ndetse no mubidukikije bikaze.
ASTM A252 Porogaramu
Ubwinshi bwumuyoboro wa ASTM A252 butuma bukwiranye nuburyo butandukanye bwa porogaramu, harimo:
- Ibirundo by'ifatizo: Iyi miyoboro ikoreshwa kenshi nk'ibirundo by'ifatizo mu mishinga y'ubwubatsi, itanga inkunga ikenewe ku nyubako, ibiraro, n'izindi nyubako.
- Imiterere yinyanja: Imiyoboro ya ASTM A252 irakwiriye gukoreshwa mubidukikije byo mu nyanja kandi irashobora gukoreshwa mukubaka ibyambu, pir, hamwe na platifomu yo hanze.
- Kugumana Urukuta: Imbaraga nigihe kirekire byiyi miyoboro bituma bikoreshwa neza mugukomeza inkuta, zifasha gutuza ubutaka no kwirinda isuri.
- Gutera-ahantu-Ibirundo bya beto: Iyo bikoreshejwe nk'isanduku yo guteramo-ibirundo bya beto,ASTM A252umuyoboro utanga urwego rukomeye ruzamura uburinganire bwimiterere ya beto.
Uruganda rukomeye muri Cangzhou
Uruganda ruzwi cyane ruherereye i Cangzhou, mu Ntara ya Hebei, rwatanze imiyoboro myiza ya ASTM A252 kuva yashingwa mu 1993. Isosiyete ifite ubuso bwa metero kare 350.000, ifite umutungo wa miliyoni 680, kandi ikoresha abakozi bagera kuri 680 bafite ubumenyi. Uruganda rwiyemeje gutanga ibicuruzwa byujuje ubuziranenge bukomeye, byemeza ko imiyoboro ya ASTM A252 yizewe kandi iramba mubikorwa bitandukanye.
Hibandwa ku guhanga udushya no guhaza abakiriya, isosiyete yabaye umuyobozi winganda, itanga ibisubizo byihariye kugirango ihuze ibyifuzo byabakiriya bayo. Hamwe nibikoresho bigezweho hamwe nabakozi bafite uburambe, barashobora gukora imiyoboro ihanitse cyane, bigatuma baba umufatanyabikorwa wizewe mubikorwa byubwubatsi nubwubatsi.
mu gusoza
Mu gusoza, imiyoboro ya ASTM A252 nigice cyingenzi cyubwubatsi bugezweho, itanga ibisobanuro byingenzi byujuje ibyifuzo bya porogaramu zitandukanye. Hamwe n’uruganda ruzwi cyane muri Cangzhou rutanga iyi miyoboro, inganda zirashobora gushingira ku bikoresho byo mu rwego rwo hejuru kugira ngo umutekano n'umutekano bihamye. Yaba ikoreshwa mubwubatsi bwa fondasiyo, inyubako zo mu nyanja cyangwa kugumana inkuta, imiyoboro ya ASTM A252 ni amahitamo akomeye kubashakashatsi n'abubatsi.
