Ikizamini cyo gufunga giyobowe kugira ngo harebwe uburyo bwo gufunga. 100% UT y'umushongi wo gufunga. Ingufu za Charpy kuri 0°C (uburemere bwa 27J, zageze kuri 50-80J). Ubugororangingo ≤ 0.2%. Igenzura rya gatatu ryakozwe na SGS Netherlands.

Porogaramu:Kwagura aho kontineri zihagarara kuri Maasvlakte 2, icyambu cya Rotterdam. Imiyoboro y'icyuma ikora nk'ishingiro ry'urukuta rw'aho amazi anyura (imizigo ihagaze) no nk'imizigo y'inzoga zometseho (imizigo ihagaze). Ubujyakuzimu bw'amazi ku butaka: metero 18. Ubutaka bugizwe n'umucanga n'ibumba ryoroshye.

Ibibazo bya tekiniki n'ibisubizo:

●Kurinda ingese ku bidukikije byo ku nkombe– Kwinjira mu mazi y’umunyu no gusiga amazi mu gace gasaba irangi rirambye. Womic yashyizeho epoxy y’amakara (miliyone 800 DFT) ifite ibice bibiri. Irangi ryatsinze ikizamini cyo gusukura umunyu mu masaha 3,000 (ASTM B117) gifite <2mm crooked from scribe. Gupima ibirori kuri 4kV nta na kimwe cyakozwe.

●Ibirundo birebire byo kuryamamo amazi menshi– Uburebure bw'ikirundo busabwa bwa metero 28 (metero 18 mu mazi + metero 10 hejuru y'umuyoboro w'ibitaka). Impande zisanzwe za metero 12 zakenera ibice 3 by'umurima. Impande zombi zatanze ibice 18 by'uburebure (isahani izungurutse) ku birundo bya mm 1.016, bigabanya ibice by'umurima kuva kuri 3 kugeza kuri 2 kuri buri kirundo. Ku birundo by'ingenzi byo gupfunyika, twatanze ibice 28 by'uburebure dusudira ibice bibiri bya metero 14 (100% UT yagenzuwe).

●Imihangayiko ikomeye mu mucanga mwinshi– Imiterere y'ubutaka irimo imiterere y'umucanga mwinshi ufite agaciro ka SPT N ka 40-60. Imiterere y'imizigo yageze kuri 70% by'imbaraga z'umusaruro. Womic yakoze ibizamini byayobowe (ubugari bwa 4t, 180°) nta mvune. Ingero z'ibizamini byakozwe byagaragaye ko nta mvune zabaye nyuma yo gupfunyika kwa 1/2 diameter. Umukiriya yavuze ko nta na kimwe cyabaye mu gihe cyo gupfunyika kwa 3.200.

●Uburemere bw'ingaruka ku ishyirwaho ry'igihe cy'itumba– Ubushyuhe bw'itumba bwa Rotterdam bushobora kugabanuka bukagera kuri -5°C. Womic yatanze ubushyuhe bwo mu cyiciro cya 2 (Charpy kuri 0°C min 27J, yageze kuri 50-80J). Ibi ntabwo bisabwa na ASTM A252 ahubwo byongeweho n'umukiriya nk'uburyo bwo kwirinda.

●Ibikoresho bijya i Maasvlakte– Imiyoboro yoherejwe iva i Shanghai ijya i Rotterdam ikoresheje ubwato bunini (iminsi 35). Kubera ko ahantu ho guhagarara hari hato, Womic yateganyije ko izajya igezwa mu mezi 4. Buri koherezwa ryahujwe na gahunda y'ubwikorezi bwo gutwara. Toni 10.800 zose zatanzwe ku gihe.

● Ibisubizo:Kwagura ikigo byarangiye mu gihembwe cya gatatu cya 2024. Ibice byose 3.200 byatsinze igeragezwa ry’umutwaro ukabije (PDA) hamwe n’ubushobozi bwo gutwara ibintu burenga ibisabwa mu gishushanyo. Umukiriya yagize ati: “Ubwiza bw’imiyoboro ya Womic n’uburyo bwo kuyitanga byari byiza cyane.” Womic Steel ubu ni umucuruzi wemewe mu mishinga y’icyambu cya Rotterdam mu gihe kizaza.
