Kutheni iStainless Steel ifanelekile kwizicelo zaseLwandle?

Insimbi engenasici yenye yezona zinto zisetyenziswa kakhulu kwiindawo zaselwandle, ngenxa yokuhlanganiswa kwayo okungaqhelekangaukuxhathisa i-corrosion, amandla, kunye nokuqina. Nokuba isetyenziswa ekwakhiweni kweenqanawa, kumaqonga angaphesheya konxweme, kufakelo lwamaphenyane, okanye kwiziseko ezingundoqo ezingaselunxwemeni, intsimbi engatyiwayo ihlala iqhuba kakuhle phantsi kweemeko ezifunekayo zokuvezwa kwamanzi etyuwa, ukufuma, kunye namaqondo obushushu aguqukayo.

Kweli nqaku, siyaphononongakutheni insimbi engenasici ifanelekile kwizicelo zaselwandle, ichaza iimpawu zayo, iingenelo, kunye nokusetyenziswa okuqhelekileyo kushishino lwaselwandle. Ukuba ubandakanyeka kubunjineli baselwandle, ukuveliswa kweenqanawa, okanye ukwakhiwa konxweme, esi sikhokelo siya kukunceda uqonde ukuba kutheni insimbi engenasici iyinto ekhethiweyo.

Ukunyangwa kokuMhlwa kwiiNdawo zaManzi eTyuwa

Esona sizathu sibalulekileyo intsimbi engenastainless ikhethwa kwiindawo zaselwandle yiyoukumelana nomhlwa, ngakumbi ukusukaiindawo ezisingqongileyo ezityebile ngekloridi njengamanzi olwandle. Intsimbi eqhelekileyo okanye intsimbi idla ngokukhawuleza emanzini anetyuwa ngenxa yokurusa kunye nemingxuma. Ngakolunye uhlangothi, insimbi engenasici iquletheichromium, eyenza i-passive oxide layer ekhusela isinyithi kwi-oxidation.

Iintsimbi zomgangatho waselwandle, ngakumbi316 kunye ne-316L, nazo zibandakanyamolybdenum, okwandisa kakhulu ukuxhathisai-chloride-induced pitting kunye ne-crevice corrosion. Oku kuzenza zilungele ukusetyenziswa ixesha elide kwindawo entywilayo okanye yeemeko zokuchaphaza.

At sakysteel, sinikezela ngekhwalithi ephezulu ye-316 kunye ne-316L yeemveliso zensimbi ezingenasici ezilungiselelwe ngokukodwa iimeko ezinzima zaselwandle.

Amandla oomatshini kunye neMfezeko yoLwakhiwo

Intsimbi engenastainless yaziwa ngayoamandla aphezulukunye nokuchasana nokudinwa, okwenza ukuba ifaneleke kwizinto ezithwala umthwalo kunye nezicwangciso zesakhiwo kwiinqanawa, iidocks, kunye ne-offshore rigs. Ngokungafaniyo nezinto ezithobisa phantsi koxinzelelo lomatshini okanye ukuvezwa kwendalo, insimbi engenasici igcina ingqibelelo nangemva kweminyaka yokusetyenziswa.

Ikwanika ukusebenza kakuhle kuzo zombiniiindawo zobushushu obuphantsi kunye nobushushu obuphezulu, ebaluleke kakhulu kwizixhobo zaselwandle ezinokuchanabeka kwimozulu embi kakhulu, impembelelo yamaza, okanye iinkqubo zoxinzelelo oluphezulu.

Olu ncedo lokomelela ukuya kubunzima lwenza intsimbi engatyiwayo ilungele:

• Iimasti kunye nokuxhoma

• Ukuqinisa Hull

• Izibophelelo zaselwandle kunye neebholithi

• Iinkqubo zokuphatha umthwalo njengeekhreyini kunye nee-winches

UkuSebenza kweendleko zeXesha elide

Nangona insimbi engenasici inokuza neendleko eziphezulu zokuqala xa kuthelekiswa nezinye izinto, inika ukubalulekaugcino lweendleko zexesha elide. Ukunganyangeki komhlwa kuthetha ukulungiswa okumbalwa, ukutshintshwa okuncinci, kunye neendleko eziphantsi zokugcinwa kubomi besakhiwo okanye inqanawa.

Imekobume yaselwandle idume ngokurhabaxa kwaye kubiza ukuyigcina. Ukukhetha insimbi engenasici ivumela abaqhubi ukuba bandise ubomi benkonzo yamacandelo abalulekileyo, ukunciphisa ixesha lokuphumla, kunye nokuhlangabezana nemigangatho yokhuseleko kunye nokungenelela okuncinci.

At sakysteel, sigxininise ekunikezeni izisombululo zensimbi ezingenasici ezinciphisa iindleko zobomi ngelixa siqinisekisa ukusebenza okuphezulu kolwandle.

Isibheno sobuhle kunye neeKhetho zokuQeda komphezulu

Ngaphandle kokusebenza, i-stainless steel inikezelaisibheno esibonakalayo, ngakumbi kwizikhephe, iinqanawa zabakhweli, kunye nolwakhiwo lwaselwandle. Umphezulu wayo ogudileyo, okhazimlisiweyo ubonelela ngenkangeleko yangoku, yobuchwephesha kwaye iyaxhathisa ibala kunye nokutshintsha kwebala.

Intsimbi engatyiwayo inokugqityezelwa ngeendlela ezahlukeneyo:

• Isipili-ipolishwekwizinto zangaphakathi zaselwandle ezitofotofo

• Ibrashi yokugqibakwizixhobo zangaphandle

• I-Bead-blasted okanye ayidluliswangaukomelezwa kokumelana nomhlwa

Ezi zigqibo aziphuculi nje inkangeleko kodwa zikwanceda ukuxhathisa i-biofouling yaselwandle kwaye zenze ukucoca kube lula, ukunciphisa umngcipheko wokwakheka kwebhaktheriya kwizicelo ezingevani namanzi.

Izicelo eziqhelekileyo zaseLwandle

Intsimbi engenastainless isetyenziswa kakhulu kuwo wonke amashishini aselwandle nangaphandle konxweme kula macandelo alandelayo:

• Ukufakwa kwephenyane: Iintsimbi, ukucandwa, iihenjisi, neeleli

• Iinkqubo zokubambelela: Amatyathanga, amakhamandela, neeswivels

• Deck hardware: Iibholadi, iiwintshi, kunye neepuli

• Ukwakhiwa kweenqanawa: Inkxaso yolwakhiwo, ii-bulkheads, kunye nemibhobho

• Iziseko ezingundoqo zonxweme: Iibhulorho, iipier kunye neenkqubo zokuxhoma

• Amaqonga aselunxwemeni: Izinyusi, iziqhagamshelo, kunye nezithintelo zokhuseleko

Ukuguquguquka kwayo kuvumela ukusetyenziswa kuzo zombini izakhiwo ezinkulu kunye namacandelo amancinci achanekileyo ekufuneka asebenze ngokuthembekileyo phantsi kokuvezwa kokusingqongileyo rhoqo.

Ukuxhathisa kwi-Biofouling kunye nokuKhula kweBhaktheriya

Kwiindawo zaselwandle, izinto zihlala zibonakaliswe kwizinto eziphilayo, i-algae, kunye ne-microorganisms. Ngokungafaniyo neenkuni okanye isinyithi esisezantsi, isinyithi esingenasici sichasai-biofouling kunye ne-bacterial adhesionngenxa yobume bayo obugudileyo kunye nobume obungenazimbobo. Oku kuyenza ilungele ukusetyenzwa kokutya kwaselwandle, i-aquaculture, kunye neenkqubo zokucoca amanzi.

Intsimbi engatyiwayo nayonon-toxic, iyenza ilungele iinkqubo ezibandakanya ukudibana namanzi, intlanzi, okanye izinto eziphila elwandle. Iqinisekisa ukuba akukho zinto ziyingozi zikhutshelwa kwi-ikhosistim engqongileyo.

Uzinzo kunye neeNzuzo zokusiNgqongileyo

Intsimbi engatyiwa aizinto ezizinzileyoehambelana nemfuno ekhulayo yolwakhiwo olunobungani nokusingqongileyo. Ipheleleinokuphinda isetyenziswekwaye inobomi benkonzo ende, ukunciphisa inkunkuma kunye nokugcina imithombo yendalo.

Ukusetyenziswa kwensimbi engenasici kwizicelo zaselwandle kunegalelo koku:

• Izixhobo ezihlala ixesha elide

• Ukunciphisa imfuno yeekhemikhali zokugquma okanye iipeyinti

• Ukunciphisa i-carbon footprint ngokuhamba kwexesha

At sakysteel, sizibophezele ekunikezeni i-marine-grade stainless steel exhasa zombini iinjongo zokusebenza kunye nokusingqongileyo.

Ukukhetha iBanga leNtsimbi eLungileyo yokuSetyenziswa eLwandle

Awona mabanga aqhele ukucetyiswa kwizicelo zaselwandle abandakanya:

• 316 / 316L iNtsimbi engatyiwa: Nge-molybdenum eyongeziweyo, la mabanga anikezela ukuxhathisa okuphezulu kwi-corrosion emanzini anetyuwa kwaye asetyenziswa ngokubanzi kwizakhiwo, oomatshini kunye nezinto zokuhombisa.

• I-Duplex Stainless Steel (umz., 2205): Inika amandla aphezulu kunye nokuxhathisa okongeziweyo kuxinzelelo lokuqhekeka kwe-corrosion, ilungele ioyile engaselunxwemeni kunye namaqonga erhasi.

• I-904L yeNtsimbi eNgatyiwayo: Isetyenziswa kwiimeko ezimandundu zaselwandle kunye nemekobume yeekhemikhali ezonakalisa kakhulu.

Ukukhetha ibakala elichanekileyo kubalulekile ekuqinisekiseni impumelelo yexesha elide kunye nokuphepha ukungaphumeleli kwangaphambi kwexesha kwiindawo zaselwandle.

Ukuqukumbela

Insimbi engenasici yinto ekhethiweyo kwizicelo zaselwandle ngenxa yayoukuxhathisa i-corrosion, amandla oomatshini, ukugcinwa okuphantsi, kunye nesibheno sobuhle. Imelana nobunzima bamanzi anetyuwa, imozulu, kunye nokusetyenziswa komsebenzi onzima, okwenza ukuba ibe sisisombululo esihlala ixesha elide kunye neendleko ezifanelekileyo kuyo yonke into ukusuka kumacandelo enqanawa ukuya kwiziseko ezingundoqo zezibuko.

Nokuba uyasinxibisa isikhephe, ulwakha i-offshore rig, okanye uhlohla iintsimbi ezingaselunxwemeni, intsimbi engenastainless ibonelela ngokusebenza, ukhuseleko, kunye nokuthembeka okufunekayo kwiindawo zaselwandle.

Ukwenziwa kwesinyithi esingenasici esiphezulu esilungiselelwe izicelo zaselwandle, trustsakysteel-Iqabane lakho elithembekileyo kwizisombululo zentsimbi engatyiwayo eyakhelwe ukomelela, ubuhle, kunye nokuqina.
