Mibvunzo Inowanzo bvunzwa:
Mubvunzo: Ndeupi musiyano uripo pakati peEN 10219 S355JRH neEN 10210 S355JRH?
A: EN 10219 ndeyezvikamu zvakapwanyika zvakaumbwa nechando (kupwanyika nekugadzira zvinoitwa patembiricha yemumba). EN 10210 ndeyezvikamu zvakapwanyika zvakapiswa (zvisina musono kana zvakapwanyika uye zvozopiswa). Kune mapaipi eLSAW, EN 10219 ndiyo mwero wakakodzera. Zvikamu zvakapwanyika zvinopisa zveEN 10210 zvinowanzova zvisina musono kana kuti ERW. Zvese zvine hunhu hwakafanana hwemakanika.
Mubvunzo: Munogona here kupa S355J2H (inopisa pa -20°C) pachinzvimbo cheS355JRH?
A: Ehe. S355J2H inowanikwa kana ikakumbirwa kuti ishandiswe pakupisa kwakaderera senge zvivakwa zvegungwa kana zveArctic. Muumbirwo wemakemikari wakafanana asi une miganhu yakamanikana uye Charpy inopikiswa pa -20°C (min 27J). Mari yekuwedzera inoshanda.
Mubvunzo: Munopa chiratidzo cheCE here pamapombi eEN 10219?
A: Ehe. Womic Steel ine chitupa cheFactory Production Control (FPC) zvichienderana neEN 10219. Tinopa CE marking ine Declaration of Performance (DoP) yemapombi anotengeswa muEuropean Economic Area (EEA). Izvi zvinoita kuti pave nekubvumidzwa kwemutero uye kuti purojekiti ibvumirwe zvakanaka.
Mubvunzo: Ndeupi hurefu hwakanyanya hwekushandisa galvanizing inopisa?
A: Mubatsiri wedu wekugadzira magasi ane hurefu hwebhavhu hwe13.5m. Saka, mapaipi anosvika 12.5m anogona kunyudzwa zvizere uye kugadzikwa. Kune mapaipi akareba, tinogona kuronga kugadzira magasi echikamu kana kuisa imwe coating (epoxy ine zinc yakawanda). Ndapota taurai nesu kuti muwane zvinodiwa pakureba kwacho.
Mubvunzo: Unogona kukuya weld flush kuti ugadzire simbi yekuvaka yakafumurwa here?
A: Ehe. Pamapaipi anooneka (semuenzaniso, makoramu ari munhandare yendege, mabhiriji), tinogona kukuya chivharo cheSAW weld kuti chinyatsobuda nemuviri wepaipi. Uku kushanda kwekuwedzera uye kunowedzera mari nenguva yekuiswa (inenge +15%). Tinokurudzira kutsanangura zvinodiwa izvi panguva yekuraira.
Mubvunzo: Ndeipi kuputira kunokurudzirwa pasimbi yekunze?
A: Kuti pave nechiedza chekunze, primer coating (epoxy ine zinc yakawanda, 60-80 microns) ndiyo yakajairika yekudzivirira kwenguva pfupi panguva yekuvaka. Kuti pave nekudzivirira kwechigarire pasina kupenda, hot-dip galvanizing (85-100 microns) ndiyo yakanakira nzvimbo dzine hukasha. Pakushandisa mukati, nzvimbo ine mafuta kana primer shoma yakakwana.
Q: Ndeipi nguva yakajairika yekuisa pombi yeS355JRH LSAW?
A: Nguva yakatarwa yekutungamira: mazuva 30-45 ehukuru hweJCOE/UOE. Kune madziro akakungurutswa ane madziro anorema (> 50mm): mazuva 45-60. Kune akasungirirwa uye akakuyiwa: wedzera mavhiki maviri. Kune hot-dip galvanizing: wedzera vhiki 1-2 zvichienderana nehurongwa hwekugezera.

Mapaipi asina kushivirira akatwasuka achishandisa hydraulic press.
● Kupfeka kwekutanga kwenzvimbo dzegwenga– Qatar ine tembiricha yepamusoro (kusvika 50°C), hunyoro hwakanyanya (kusvika 85% munguva yechando), uye jecha rinobhururuka nemhepo. Yakaiswa papombi dzese ne epoxy primer (60 microns). Yakapfurwa nesalt spray test (1,000 hours, ASTM B117) ine creep isingasviki 2mm. Kuonekwa kwezororo pa2kV. Kunamira kwakayerwa pa8 MPa (min 5 MPa).
● Zvinhu zvakaoma panguva yekuvakwa kweFIFA– Kuvakwa kwenhandare kwaive nehurongwa hwakaoma (2020-2021). Womic yakaendesa mapaipi muzvinhu zvina (imwe neimwe yaive matani 800-1,000) kwemwedzi misere. Mapaipi akatumirwa kubva kuShanghai kuenda kuHamad Port (Doha), ndokuzoendeswa nemotokari makiromita makumi mana nemashanu kunzvimbo yenhandare. Nekuda kwezvirambidzo zveCOVID-19, vaongorori veWomic vakatadza kufamba. Takaronga kuongororwa kwevakaona vari kure kuburikidza nemavhidhiyo ari live feed (TÜV online). Matani ese 3,480 akagamuchirwa ari kure.
● Kusimba kwesimba remhepo pakupisa kwakaderera– Kunyangwe Qatar ichipisa, husiku munguva yechando hunogona kudonha kusvika 10°C, uye denga remba rinoonekwa pachena. EN 10219 S355JRH inoda Charpy impact pa0°C (27J min). Womic yakasvika 80-120J, kupfuura zvaidiwa. Mishumo yebvunzo yakabatanidzwa muCE DoP package.
●Mhedzisiro:Nhandare yeAl Wakrah yakavhurwa muna 2022 uye yakaitirwa mitambo mitanhatu yeWorld Cup. Denga resimbi rakarumbidzwa zvikuru nekuda kwekugadzirwa kwaro kwakanaka. Mugadziri wesimbi (mugadziri wesimbi anotungamira muEurope) akataura kuti hapana kana kukanganisa kweweld panguva yekumiswa kwayo. Mapaipi ese eLSAW akakodzera zvakanaka panzvimbo iyi pasina kugadziriswazve. Womic Steel yakagamuchira tsamba yekutenda kubva kumugadziri mukuru we "kunyatsorurama uye kupedzisa weld." Nhandare iyi ichiri kushanda senzvimbo yemitambo nemitambo inoshandiswa zvakasiyana-siyana.
