Umuyoboro w'icyuma wa EN 10219 S355JRH LSAW: Ubushobozi bwo gukora n'ibisobanuro by'ibicuruzwa

Kuki Womic Steel yagenewe EN 10219 Structural Pipe?

● Ikimenyetso cya CE (EN 10219) kirimo Itangazo ry'Imikorere

● Ubugari bunini bugera kuri mm 2,500 (98″) – ni bwiza cyane ku nyubako nini

● Urukuta ruremereye rugera kuri mm 80 – ku nkingi ziremereye cyane n'inkuta z'ibiraro

● 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 kugira ngo rigenzurwe na CE

Toni zisaga 300.000 zatanzwe ku mishinga y'i Burayi n'amahanga

Ibibazo Bikunze Kubazwa:

Q: Ni irihe tandukaniro riri hagati ya EN 10219 S355JRH na EN 10210 S355JRH?
A: EN 10219 igenewe ibice bikonje bifite ubushyuhe buvanze (gusudira no gushushanya bikorwa ku bushyuhe bw'icyumba). EN 10210 igenewe ibice bishyushye birangije ubushyuhe (bidafite ubushyuhe cyangwa bivanze hanyuma bigatunganywa n'ubushyuhe). Ku miyoboro ya LSAW, EN 10219 ni yo ngenderwaho ikenewe. Ibice bishyushye birangiye muri EN 10210 akenshi biba bifite ubushyuhe buvanze cyangwa ERW. Byombi bifite imiterere isa ya mekanike.

Q: Ese ushobora gutanga S355J2H (ingaruka kuri -20°C) aho gutanga S355JRH?
A: Yego. S355J2H iraboneka iyo uyisabye kugira ngo ikoreshwe mu bushyuhe buri hasi nko mu nyubako zo mu nyanja cyangwa mu gice cyo hasi. Imiterere y'imiti isa ariko ifite imipaka ikomeye kandi ihamye ko ishobora gutera Charpy kuri -20°C (ubuso bwa 27J). Hari n'ikiguzi cy'inyongera.

Q: Ese mutanga ikimenyetso cya CE ku miyoboro ya EN 10219?
A: Yego. Womic Steel ifite icyemezo cyo kugenzura umusaruro w’uruganda (FPC) nk’uko biteganywa na EN 10219. Dutanga ikimenyetso cya CE kirimo Itangazo ry’imikorere (DoP) ku miyoboro igurishwa mu Karere k’Ubukungu bw’u Burayi (EEA). Ibi bituma umushinga wemerwa neza kandi ugahabwa agaciro.

Q: Ni uburebure bungana iki bwo gukoresha galvanizing ishyushye?
A: Umufatanyabikorwa wacu wo gukaraba afite uburebure bwa metero 13.5. Kubwibyo, imiyoboro ifite uburebure bwa metero 12.5 ishobora kwinjizwamo neza no gukaraba. Ku miyoboro miremire, dushobora gushyiraho uburyo bwo gukaraba ibice cyangwa tugashyiraho ubundi buryo bwo gusiga (epoxy irimo zinc). Twandikire ku bipimo byihariye by'uburebure.

Q: Ese ushobora gusya icyuma gishyushya ibyuma byakozwe mu bwubatsi?
A: Yego. Ku miyoboro igaragara (urugero: inkingi ziri ku kibuga cy'indege, imitako y'ibiraro), dushobora gusya umupfundikizo wa SAW weld kugira ngo uhuzwe n'umubiri w'umuyoboro. Iki ni igikorwa cy'inyongera kandi cyongera ikiguzi n'igihe cyo kuyikoresha (hafi + 15%). Turakugira inama yo gusobanura iki gisabwa mu gihe cyo kuyitumiza.

Q: Ni iyihe paki isabwa ku byuma byo hanze byubatswe?
A: Ku bijyanye no gushyira hanze, irangi rya primer (epoxy ikungahaye kuri zinc, mikoroni 60-80) ni ryo risanzwe rikoreshwa mu kurinda by'agateganyo mu gihe cyo kubaka. Kugira ngo rikomeze kurindwa nta gusiga irangi, gushyushya galvanizing (mikoroni 85-100) ni byiza cyane mu bidukikije bikaze. Ku bijyanye no gushyira imbere, ubuso busizwe amavuta cyangwa primer ntoya birahagije.

Q: Igihe gisanzwe cyo gukoresha umuyoboro wa S355JRH LSAW ni ikihe?
A: Igihe gisanzwe cyo gutangira: iminsi 30-45 ku ngano za JCOE/UOE. Ku rukuta ruremereye rwa plaque (> 50mm): iminsi 45-60. Ku rukuta rwometseho n'ururabo rwo hasi: ongeramo ibyumweru 2. Ku rukuta rushyushye: ongeramo icyumweru 1-2 bitewe na gahunda yo koga.

Icyitonderwa cy'umushinga - Imiterere y'igisenge cya sitade ya Al Wakrah (Qatar)

Igihugu:Katari (Al Wakrah, mu majyepfo ya Doha)
Igipimo n'Icyiciro:EN 10219 S355JRH (hamwe n'inyongera ya Charpy kuri 0°C hamwe no gusya ibyuma byashyizwe ahagaragara)
Ingano n'ingano:

● OD 508mm (20″) × Uburemere 16.0mm – metero 4.500 (hafi toni 830) yakozwe na UOE process

● OD 610mm (24″) × Uburemere 20.0mm – metero 3.200 (hafi toni 930) yakozwe na UOE process

● OD 813mm (32″) × Ubwinshi 25.0mm – metero 1.800 (hafi toni 880) yakozwe na JCOE process

● OD 1,016mm (40″) × Uburemere 30.0mm – metero 1,200 (hafi toni 840) ikorwa n'umugozi umwe w'icyuma gipfundikiye
Igiteranyo:Metero 10.700 (10.7 km) z'umuyoboro w'inyubako, toni zigera kuri 3.480

Ibisobanuro:Impera zisanzwe zifite chamfer (yo gusudira ku gice cyo hasi), imigozi yo gusudira ikoreshwa mu gusuka ku gice cyo hasi cy'umuyoboro (ibisabwa mu bwubatsi), irangi rya primer (epoxy ikungahaye kuri zinc, mikoroni 60). Ikizamini cyo gufunga gitegetswe, ikizamini cyo kugonda giyobowe, 100% UT y'umushongi wo gusudira hamwe na 10% RT. Ingufu za Charpy kuri 0°C (uburemere bwa 27J, zageze kuri 80-120J). Ikimenyetso cya CE gifite Itangazo ry'Imikorere. Igenzura rya gatatu ryakozwe na TÜV Rheinland. Imiyoboro yose yasabaga kugororoka ≤ 0.15% (ikomeye kurusha 0.2%).

Porogaramu:Sitade ya Al Wakrah (izwi kandi nka Sitade ya Al Janoub), imwe mu mbuga za FIFA zo mu gikombe cy'isi cya 2022. Igisenge kigizwe n'urushundura rw'insinga rufite impeta yo gukandagiraho icyuma n'imigozi ya radial. Imiyoboro ya LSAW yakoreshejwe ku mpeta yo gukandagiraho (1,016mm OD) n'imigozi ya radial truss (813mm, 610mm, 508mm). Igisenge gifite umurambararo wa metero 200 kandi gitwikiriye imyanya 42,000.

Ibibazo bya tekiniki n'ibisubizo:

● Icyuma cyashyizwe ahagaragara mu bwubatsi - ibisabwa mu gusya hakoreshejwe ubutare– Inyubako y'igisenge cya sitade igaragara imbere n'inyuma. Umukiriya yasabye ko imigozi yo gusudira ishyirwa hasi ku gice cy'umuyoboro kugira ngo igaragare neza. Womic yasudiraga akoresheje imashini zisya zikoresha ikoranabuhanga hanyuma agasoza n'intoki. Buri gusudira yagenzuwe niba imeze neza (ubuso bugoye bwa Ra ≤ 6.3μm). Ibi byongereye ibyumweru 2 ku musaruro ariko byageze ku musozo ukenewe.

● Gusaba ko ibintu birushaho kugororoka– Impeta yo gukanda yasabaga imiyoboro ifite ubugororangingo ≤ 0.15% (EN 10219 isanzwe yemerera 0.2%). Womic yakoresheje UOE na JCOE hamwe n'uburyo bwo kwagura imiyoboro kugira ngo igere ku bugororangingo bwa 0.08-0.12%. Buri muyoboro wapimwe ku mbonerahamwe y'ubugororangingo (alignment ya laser). Imiyoboro idakira yagororokaga hakoreshejwe imashini ikoresha hydraulic.

● Igitambaro cyo gusiga ku butaka bw'ubutayu– Qatar ifite ubushyuhe bwinshi (kugeza kuri 50°C), ubushuhe bwinshi (kugeza kuri 85% mu gihe cy'itumba), n'umucanga wo mu kirere. Imashini ya epoxy ikunzwe cyane na zinc (microns 60) yashyizwe ku miyoboro yose. Ipaki yatsinze ikizamini cyo gutera umunyu (amasaha 1.000, ASTM B117) ifite ubushyuhe buri munsi ya 2mm. Gupima ubushyuhe kuri 2kV. Gufata byapimwe kuri 8 MPa (ubushyuhe bwa 5 MPa).

● Ibikoresho bigoye mu gihe cyo kubaka FIFA– Iyubakwa rya sitade ryari rifite gahunda ikomeye (2020-2021). Womic yatanze imiyoboro mu buryo bune (buri imwe ya toni 800-1.000) mu mezi 8. Imiyoboro yoherejwe iva i Shanghai ijya i Hamad Port (Doha), hanyuma ikamyo ijya aho sitade iherereye mu birometero 45. Kubera ko hari amategeko ya COVID-19, abagenzuzi ba Womic ubwabo ntibashoboraga kugenda. Twateguye igenzura ryakorewe kure hifashishijwe videwo (TÜV online). Toni 3.480 zose zemerewe kure.

● Ubukomere ku bushyuhe bushoboka bwo mu kirere– Nubwo Qatar iba ishyushye, nijoro mu gihe cy'itumba ishobora kugabanuka ikagera kuri 10°C, kandi imiterere y'igisenge ikaba yagaragaye. EN 10219 S355JRH isaba Charpy gutera kuri 0°C (iminota 27J). Womic yageze kuri 80-120J, hejuru cyane y'ibisabwa. Raporo z'ibizamini zashyizwe muri paki ya CE DoP.

●Ibisubizo:Sitade ya Al Wakrah yafunguwe mu 2022, yakira imikino itandatu y'igikombe cy'isi. Inyubako y'icyuma yashimwe cyane kubera imiterere yayo myiza. Rwiyemezamirimo (umufundi w'ibyuma ukomeye mu Burayi) yavuze ko nta kibazo na kimwe yahuye nacyo mu gihe cyo kuyishyira ku isoko. Imiyoboro yose ya LSAW yahuye neza aho hantu nta n'ivugururwa ryakozwe. Womic Steel yahawe ibaruwa yo gushimira rwiyemezamirimo mukuru kubera "ubuhanga bwiza mu miterere no kurangiza neza imiyoboro." Sitade ikomeje gukora nk'ahantu hakorerwa siporo n'ibirori byinshi.
