Liquefied natural gas (LNG), ine chikamu chikuru methane, ndeyepamusoro-mhando, yakachena, inoshanda uye yakanakira "mafuta egirinhi", ayo anoonekwa seyakanyanya kushambidzika simba pasi rose uye imwe yeakanyanya kukosha masosi emakumi maviri nerimwe. zana remakore.
9% nickel simbi imhando yesimbi yakadzika-kabhoni yakadzimwa uye yakadzikama, ine 9% nickel element, ine yakanakisa weldability, mutengo wakaderera, simba rakakwirira uye yakanakisa -196 °C yekupedzisira-yakaderera tembiricha kuoma uye zvimwe zvakanaka zvave zvakanyanya. simba mukuvakwa kwematangi makuru ekuchengetedza LNG. Isu takazvipira kugadzira epamusoro-yekupedzisira welding zvinobatika uye nekupa zvinotsigira zvinobatika zvinobatika uye welding zvigadziriso zve9% nickel simbi welding consumables semupi wemhando yepamusoro.
"Race the nondo" - chii chinoita kuti zvigadzirwa zvedu zvewelding zvioneke
Pasi pekudzvinyirirwa kwesimba repasi rose uye nyaya dzezvakatipoteredza, indasitiri yeLNG kumba nekune dzimwe nyika inoramba ichikwira. Iyo yekupedzisira-yakaderera tembiricha yekuchengetera mamiriro eLNG inonetsa yakaoma kune iyo inotambira zvinhu uye welding zvinodyiwa. Kwenguva yakareba, 9% yezvinobatika zvewelding zvenickel simbi zvakadzorwa nezvinotengeswa kunze kwenyika welding. Kuti tipwanye kuvharika kwehunyanzvi hwekune dzimwe nyika uye kusangana nezvinodiwa zveLNG indasitiri yenzvimbo, takatungamira mukupa yakakwana 9% nickel simbi inoenderana newelding inobatika uye welding process, uye takamira kunze kwechaunga nemhando yepamusoro yechigadzirwa, nyanzvi yehunyanzvi timu. uye sevhisi yakatsaurirwa uye ine mufungo.
Iyo yakazara yakazara yekutsigira welding consumables uye welding maitiro anogadzirwa
Kwese-kutenderera kugovera kune kudiwa kwemusika
Isu takagadzira uye takagadzira huwandu hwakazara hwemhando yepamusoro, 9% nickel simbi inofananidzwa nekushandisa uye welding maitiro, anosanganisira electrode, akanyura arc waya uye flux musanganiswa, flux-cored waya dzekuzara-nzvimbo welding, uye argon arc welding waya. Iyi nhevedzano yezvigadzirwa ine yakanakisa weldability uye michina zvivakwa, uye iyo CTOD uye yekudonhedza huremu mhedzisiro yakanakisa, iyo chaiyo chigadzirwa ruzivo inoratidzwa patafura pazasi.

"Zvose zvakaoma uye zvinyoro" - unhu hwakaoma, basa rinoshingaira
Zvishandiso zvekambani yedu zvevelding zvakashingirira bvunzo dzemusika neakanakisa welding inodyiwa mhando, uye ndivo vekutanga kuwana patented welding consumables tekinoroji ye9% nickel simbi muChina. Tichitsigirwa neR&D yakasimba, tekinoroji uye timu yebasa, isu tinobatsira vatengi kuwana yakakwana 9% nickel simbi mhinduro.

"Kutungamira indasitiri, inotumbuka kwese kwese" - kuratidza simba nekuita
Isu tanga tichisimudzira kugariswa kwezvinhu zvinobatisa welding zve9% nickel-simbi LNG matangi ekuchengetedza. Kubva 2016, Jingqun's 9% nickel steel welding consumables yakashandiswa zvinobudirira kumatangi emugungwa eLNG uye yakawana mibairo yakawanda inoshamisa. Mushure mezvo, yakabuda mumapurojekiti maviri e50,000 cubic metres bimetallic LNG land tank tank muChangchun muna 2021, uye yakatevedzana yakasimudzirwa uye yakashandiswa mu 200,000 cubic metres yakakura LNG land tank tank.
