Umuyoboro w'icyuma wa ASTM A500 Grade C LSAW: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Kuki Womic Steel ikoreshwa mu gupima ASTM A500 Grade C?

● Ubunini bunini bugera kuri mm 2,500 (98″) – ni bwiza cyane ku nkingi ziremereye na monopole zo gutwaramo

● Urukuta ruremereye rugera kuri mm 80 – ku bikoresho by'ubwubatsi biremereye

● Uburyo bwo gusya ibyuma by'ubwubatsi byashyizwe ahagaragara

● Gusiga irangi rya primer na hot-dip galvanizing birahari

● Igenzura ry’umuntu wa gatatu (SGS, BV, TÜV) ryemejwe

● Ibiciro bihangana ku mishinga minini y'ibikorwa remezo

Ibibazo Bikunze Kubazwa:

Q: Ni irihe tandukaniro riri hagati ya ASTM A500 Grade C na ASTM A53 GR.B ku miyoboro y'inyubako?
A: Icyiciro cya C gifite imbaraga nyinshi cyane: umusaruro wa MPa 345 ugereranije na MPa 240 kuri A53. Icyiciro cya C gifite kandi ubushobozi bwo kwihanganira ibintu bikomeye kandi gisaba ikizamini cyo kugorora. Ku nkingi n'imizigo bitwara imizigo, Icyiciro cya C ni cyo cyiza. A53 GR.B yemewe ku bice by'inyongera n'inyubako zitari iz'ingenzi.

Q: Ese ASTM A500 isaba gupimwa ingaruka (Charpy)?
A: Oya. ASTM A500 ntabwo itegeka Charpy isuzuma ingaruka. Ariko, ku bipimo biri hasi (urugero, Arctic, amwe mu makode y'ikiraro), injeniyeri zishobora kongeramo ibisabwa by'inyongera. Womic ishobora gutanga isuzuma ry'ingaruka za Charpy ku giciro cy'inyongera (ubusanzwe kuri 0°C cyangwa -20°C) niba byavuzwe.

Q: Ese ushobora gutanga A500 Grade C hamwe na hot-dip galvanizing yo gukoreshwa hanze?
A: Yego. Dutanga galvanizing ishyushye kuri ASTM A123. Uburebure ntarengwa bw'ubwogero bwacu bwo gukaraba ni metero 12.5. Ku miyoboro miremire, dushobora gushyiraho galvanizing igizwe n'ibice cyangwa tugashyiraho ubundi buryo bwo gusiga (epoxy irimo zinc). Nyamuneka garagaza uburebure wifuza.

Q: Ni uburebure ntarengwa bungana iki ushobora gukora ku muyoboro wa A500 Grade C LSAW?
A: Uburebure ntarengwa busanzwe ni metero 18 (JCOE) cyangwa metero 24 (UOE) ku gipimo cya ≤ mm 1,220. Ku gipimo kinini (icyuma gipfundikiye), uburebure ntarengwa busanzwe ni metero 12-18 bitewe n'ingano y'icyuma. Ku burebure burenga metero 18, dushobora gusudira ibice byinshi kuva ku mpera kugeza ku mpera (circumferential SAW welds). Twandikire ku byo ukeneye byihariye.

Q: Ese mukora igenzura ry’imiyoboro ya A500 Grade C ku ruhande rwa gatatu?
A: Yego. Dukorana na SGS, BV, TÜV, n'izindi nzego. Igenzura rishobora kuba rikubiyemo isuzuma ry'amaso n'ibipimo, isuzuma ryo gupfunyika, isuzuma rya UT cyangwa RT ry'imashini zisudira, n'isuzuma ry'imiti/ingufu. Dutanga icyemezo cya EN 10204 Type 3.1 nk'uko bisanzwe; Ubwoko bwa 3.2 buraboneka iyo ubisabye.

Q: Ni ryari igihe gisanzwe cyo gutanga umuyoboro wa A500 Grade C LSAW gikoreshwa?
A: Igihe gisanzwe cyo gutangira: iminsi 30-45 ku ngano za JCOE/UOE. Ku rukuta ruremereye rwa plaque (> 50mm): iminsi 45-60. Ku gushyushya galvanizing: ongeramo icyumweru 1-2. Ku gusya hakoreshejwe uburyo bwo gusuka (gutunganya inyubako): ongeramo ibyumweru 2.

Icyitonderwa cy'umushinga - Imiterere y'inyubako z'umunara wa sitade ya Los Angeles (USA)

Igihugu:Leta Zunze Ubumwe za Amerika (Inglewood, muri Kaliforuniya – agace ka sitade ya SoFi)
Igipimo n'Icyiciro:ASTM A500 Grade C (hamwe n'inyongera ya Charpy kuri 0°C)
Ingano n'ingano:

OD 610mm (24″) × Ubwinshi 16.0mm – metero 2.400 (hafi toni 560) zakozwe na UOE process

OD 813mm (32″) × Ubwinshi 20.0mm – metero 1.800 (hafi toni 700) yakozwe na JCOE process

OD 1,016mm (40″) × Ubwinshi 25.0mm – metero 900 (hafi toni 550) ikorwa n'umugozi umwe w'icyuma gipfundikiye

OD 1,220mm (48″) × Ubwinshi 30.0mm – metero 600 (hafi toni 530) ikorwa n'umugozi umwe w'icyuma gipfundikiye
Igiteranyo:Metero 5.700 (5.7 km), hafi toni 2.340

Ibisobanuro:Impera zisanzwe zifite chamfer (yo gusudira ku matako), imigozi yo gusudira hasi (ibikenewe mu miterere yabyo), epoxy primer coating ikungahaye kuri zinc (microns 60). Ikizamini cyo gufunga (nta mvune kuri 1/3 diameter yo gufunga). Ikizamini cyo gufunga giyobowe cyo kugenzura ubushobozi bwo gusudira. 100% UT y'umushongi wo gusudira. Ingufu za Charpy kuri 0°C (uburemere bwa 27J, zageze kuri 60-90J). Ubugororangingo ≤ 0.15% (burenze igipimo cya A500). Igenzura rya gatatu ryakozwe na SGS USA.

Porogaramu:Imitako y'imitako ikora neza kandi ikora neza ikikije sitade ya SoFi na pariki ya Hollywood i Los Angeles. Imiyoboro ya LSAW ikora nk'inkingi zikomeye zihagaze n'inkingi zigororotse ku minara minini y'ubwubatsi "ikomeye" (ifite uburebure bwa metero 60) ishyigikira ibyapa, amatara, ndetse ikanakora nk'ahantu nyaburanga ho kubaka. Uyu mushinga wasabye icyuma cyambaye ubusa gifite irangi ryoroshye kandi gisa neza.

Ibibazo bya tekiniki n'ibisubizo:

● Icyuma cyashyizwe ahagaragara mu bwubatsi - gusya no kurangiza– Iminara igaragara uhereye kuri sitade no mu nkengero zayo. Womic yakoreshaga uburyo bwo gusya hakoreshejwe uburyo bworoshye hanyuma ikarangizwa n'intoki kugira ngo igere ku buso bwiza (Ra ≤ 6.3μm). Twanashyizeho irangi ry'ibanze ringana (epoxy ikungahaye kuri zinc, ibara ry'umukara ryoroheje ryagaragajwe n'umuhanga mu by'ubwubatsi). Buri muyoboro wagenzuwe niba ubushyuhe bwa weld bugenda neza n'itsinda ry'abashinzwe ibibazo by'abakiriya.

● Ibisabwa mu gace k'imitingito - ubushobozi bwo kugenda no gukomera– Los Angeles iri mu cyiciro cya D cy’igishushanyo cya “Seismic Design” (ingaruka zikomeye ku mitingito). Ubusanzwe ASTM A500 Grade C ntisaba isuzuma ry’ingaruka. Injeniyeri w’imiterere yongeyeho Charpy isabwa ku ngaruka za 27J kuri 0°C. Womic yatoranyije plaque zifite karuboni igenzurwa (0.20-0.22%) na manganese (1.15-1.25%) kandi yageze kuri 60-90J kuri 0°C, hejuru cyane y’igisabwa.

●Ibice binini bifite uburebure butose– Amaguru amwe y’umunara yari yagabanutse (ameze nk’ibuye ry’umuhondo). Womic yatanze imiyoboro igororotse hanyuma ikorwa na rwiyemezamirimo mu bice byagabanutse. Twatanze uburyo bwo kugenzura imiterere y’urukiramende (≤ 0.5%) kugira ngo byorohereze inzira yo gufunga. Imiyoboro yashyizweho imirongo y’icyerekezo kugira ngo harebwe ko isudira ihoraho.

●Igiti cyo gusiga ku nkombe z'inyanja– Sitade ya SoFi iherereye ku birometero 5 uvuye ku Nyanja ya Pasifika, ifite umunyu mwinshi. Imashini ya epoxy ikungahaye kuri zinc (micrones 60) yashyizwe ku miyoboro yose. Irangi ryatsinze ikizamini cyo gutera umunyu mu masaha 1.000 (ASTM B117) gifite munsi ya mm 2. Kumenya ko hari ikiruhuko kuri 2kV nta ngaruka zabaye.

●Ibikoresho bijya aho imirimo y'ubwubatsi ikorerwa– Iterambere rya Pariki ya Hollywood ni rimwe mu mishinga minini y’ubwubatsi bw’imijyi muri Amerika. Hagombaga gutegurwa uburyo bwo kohereza toni 2,340 z’imiyoboro minini. Womic yazanye imiyoboro mu buryo butandatu mu mezi 8, buri imwe ikaba yaragombaga kuhagera mbere gato yo gushyirwaho. Imiyoboro yoherejwe iva i Shanghai ijya ku cyambu cya Los Angeles, hanyuma ikagezwa mu modoka mu birometero 8 igera aho yari iri. Twakoresheje amakontena arambuye ku miyoboro ya 1,016mm na 1,220mm kugira ngo twirinde kwangirika.

●Ibisabwa na Amerika mu kugura Amerika– Uyu mushinga wasabye ko ibyuma byo mu mahanga birekurwa kuko inganda zo mu gihugu muri Amerika zitashoboraga gukora uburebure bunini (1,220mm) mu bugari bw'urukuta rwasabwaga mu gihe cyagenwe. Womic yatanze inyandiko zuzuye zirimo ibyemezo by'inganda, igihugu zikomokamo, n'uburyo ibikoresho byazo byakurikiranwa. Ubwishyu bwemewe na nyirabwo.

●Ibisubizo:Inyubako z'umunara w'amashanyarazi zuzuye mu 2022. Zabaye ikintu kizwi cyane muri sitade ya SoFi. Rwiyemezamirimo yavuze ko imiyoboro yose ya LSAW yahuye neza nta kuvugurura. Icuma cyagaragaye cyashimwe n'umwubatsi. Kuva icyo gihe, Womic Steel yatumiwe gupiganirwa indi mishinga y'ibyuma by'ubwubatsi muri Amerika.
