Mu kubaka no kuvugurura abaturage, guhitamo ibikoresho ni ngombwa kugirango ubunyangamugayo no kuramba. Ibikoresho bimwe byubahwa cyane mu nganda ni ASTM A252. Ibishushanyo mbonera bya silindrike, urukuta rwa Nomine Muri iyi blog, tuzakuramo kwibira mubikorwa byingenzi no gusaba ASTM A252 ubunini bwumuyoboro mugihe hashyirwaho ubushobozi bwuruganda rukurikira rushingiye kuri Cangzhou, Intara ya Hebei.
Ibisobanuro nyamukuru bya ASTM A252 Imiyoboro
ASTM A252 nicyo kimenyetso gisanzwe cyerekana ibisabwa kubarize ibiganza bisuye kandi bidafite ishingiro. Iyi miyoboro yagenewe gukoreshwa nkabanyamuryango bihamye bihoraho cyangwa nkibishishwa kugirango bibe ibirundo bya beto. Ibisobanuro by'ingenzi bya ASTM A252 birimo:
1. Icyiciro cyibikoresho: Ibisobanuro birimo amanota atatu yicyuma: Icyiciro cya 1, icyiciro cya 2, hamwe nicyiciro cya 3. Buri cyiciro gifite imbaraga zimbaraga zitanga umusaruro, zifite icyiciro cya 3 gifite imbaraga nyinshi zitanga umusaruro kandi zikwiranye na porogaramu ziremereye.
2. Ingano: ASTM A252 Imiyoboro iraboneka muburyo butandukanye bwurukuta rwinzobere, yemerera guhinduka mugushushanya no gusaba. Iyi miyoboro iraboneka muri diameters kuva kuri santimetero 6 kugeza kuri santimetero 60 kugirango uhuze ibisabwa bitandukanye byumushinga.
3. Amahitamo meza kandi adafite imbaraga:ASTM A252 UmuyoboroIrashobora kubyara gusudira cyangwa bidafite agaciro, gutanga amahitamo ashingiye kubikenewe byumushinga wawe. Umuyoboro usudise muri rusange utanga ibiciro byinshi, mugihe umuyoboro udafite imbaraga utanga imbaraga nyinshi kandi wizewe.
4. Kurwanya ruswa: Ukurikije porogaramu, ASTM A252 irashobora kwishyurwa cyangwa kuvurwa kugirango yongere ingwate zabo
ASTM A252 Porogaramu
Ibisobanuro bya Astm A252 bituma bikwiranye nuburyo butandukanye bwa porogaramu, harimo:
- Ibirungo bya Fondasiyo bikoreshwa nk'urufatiro rw'imishinga mu mishinga yo kubaka, zitanga inkunga ikenewe ku nyubako, ibiraro, n'izindi nzego.
- Inzego za Marine: ASTM A252 ikwiranye no gukoresha ibidukikije kandi irashobora gukoreshwa mukubaka ibibuga, Piers, hamwe no guhinduranya kwa Offshore.
- Gumana inkuta: Imbaraga n'imbara by'izi miyoboro bituma bikwiranye no gukoresha mu rukuta, bifasha gutuza ubutaka no gukumira isuri.
- Ahantu-mu-Gukoresha Ibirundo bya beto: Iyo bikoreshejwe nka casing yo guta ibirundo bya beto,ASTM A252Umuyoboro utanga urwego rukomeye rwongera ubusugire bwa beto.
Uruganda rukora muri Cangzhou
Uruganda ruzwi cyane ruherereye muri Cangzhou, Intara ya Hebei, rumaze kubyara ATTM ifite ireme muri A252 kuva ishyirwaho ryayo mu 1993. Isosiyete ikubiyemo akarere ka metero kare 350.000, ifite umutungo wose w'intama miliyoni 680, kandi ukoreshe hafi 680 abakozi babahanga. Uwayikoze yiyemeje gutanga ibicuruzwa byujuje ubuziranenge bukomeye, butuma Astm yayo ari252 yizewe kandi iramba mu buryo butandukanye.
Hamwe no kwibanda ku guhanga udushya no kunyurwa kwabakiriya, isosiyete yabaye umuyobozi winganda, itanga ibisubizo byihariye kugirango yubahirize abakiriya bayo. Hamwe nibikoresho-byubuhanzi hamwe nabakozi b'inararibonye, barashobora kubyara imiyoboro ihanitse, bikabafasha mu mishinga yizewe kumishinga yubwubatsi nubuhanga.
Mu gusoza
Mu gusoza, ASTM A252 ni igice cyingenzi cyo kubaka kigezweho, gutanga ibisobanuro byingenzi byujuje ibyifuzo byinshi. Hamwe numutungo uzwi muri Cangzhou utanga iyi miyoboro, inganda zirashobora kwishingikiriza kubikoresho byiza kugirango umutekano ubone umutekano n'umutekano wimiterere. Niba ikoreshwa mu buhanga bw'umusingi, inyokori zo mu nyanja cyangwa kugumana inkuta, ASTM A252 ari amahitamo y'ingenzi kuba injeniyeri n'abamwubatsi.
