Steel Tubes In The Marine & Offshore Industry

Ukwakhiwa Kwemikhumbi kanye Nezakhiwo Zasolwandle
Amashubhu ensimbi asetshenziswa kakhulu ekwakhiweni kwemikhumbi ukuze kwakhiwe ama-hulls, amadekhi, ama-mass, kanye nezinhlelo zokubopha. Isilinganiso sabo esiphezulu samandla nesisindo sinomthelela ekuqineni kwesakhiwo semikhumbi ngenkathi kunciphisa isisindo, okubalulekile ekusebenzeni kahle kukaphethiloli kanye namandla okulayisha. Izingxenye zesakhiwo ezingenalutho kanye namafreyimu angama-tubula ahlinzeka ngokumelana okuhle kakhulu nokugoba nokugoba, okwenza imikhumbi ikwazi ukumelana nezimo zasolwandle ezigubhayo. Ukwengeza, amashubhu ensimbi asetshenziswa ezinhlelweni zamapayipi emikhunjini ukuthutha uphethiloli, amanzi, nolunye uketshezi ngokuphepha.

Ama-Offshore Oil & Gas Platforms
Ekuhloleni nasekukhiqizeni uwoyela negesi phesheya kwezilwandle, amashubhu ensimbi akha umgogodla wezakhiwo zesikhulumi. Asetshenziswa njengemilenze yebhantshi, inqwaba, nezinsimbi zokusekela isisindo seplatifomu futhi amelane namandla emvelo njengamagagasi, umoya, namaza. Ukumelana nokukhathala kwamashubhu ensimbi kubalulekile kulezi zindawo zasolwandle ezinamandla, lapho ukunyakaza okungapheli kanye nengcindezi kwenzeka. Izingubo ezimelana nokubola kanye nezinhlelo zokuvikela i-cathodic zivame ukusetshenziswa kumashubhu ensimbi ukuze avikele ekugqwaleni kwamanzi olwandle, andise impilo yawo yesevisi.

I-Subsea Pipelines kanye namaRisers
Amashubhu ensimbi abalulekile kumapayipi angaphansi kolwandle athutha uwoyela, igesi, nolunye uketshezi olusuka emithonjeni engaphansi kwamanzi luye ezindaweni zokucubungula ngasogwini noma ezisekelweni ezintantayo. Lamapayipi kufanele abekezelele ukucindezela okukhulu, izinga lokushisa eliphansi, namanzi olwandle agqwala. Ukuqina kwensimbi nekhono lokwenziwa ngamafomu angenamthungo noma ashiselwe kuqinisekisa ubuqotho nokuphepha kwamapayipi. Izikhuphukeli—amashubhu ensimbi amile axhuma amapayipi olwandle nezinkundla ezingaphezulu—futhi athembele emandleni ensimbi nokuvumelana nezimo ukuze amukele ukunyakaza kweplatifomu namaza olwandle.

Amasistimu Wokuhamba Nezinto Zasolwandle
Amashubhu ensimbi asetshenziswa ezinhlelweni zokubopha ukuze amise izinkundla ezintantayo, imikhumbi, namayunithi okukhiqiza antantayo (ama-FPU) ngokuvikelekile phansi olwandle. Izingxenye zensimbi ye-Tubular kumaketanga okubopha, amahange, nezixhumi zinikeza amandla adingekayo okuqina kanye nokumelana nokukhathala ukuze kugcinwe indawo ezimweni ezinzima zasolwandle. Ukwengeza, amashubhu ensimbi asetshenziswa ekwakhiweni kwama-cranes asolwandle, amawintshi, nezingalo zokulayisha, ezisekela imithwalo esindayo nokusebenza okuphindaphindwayo ezindaweni ezigqwalile.

Amachweba, Izikhumulo Semikhumbi, Nengqalasizinda Yasogwini
Amashubhu ensimbi asetshenziswa kakhulu ekwakhiweni kwezinsimbi, amajethi, izindawo zokubhoboza amanzi, nezindonga zama-quay. Izinqwaba zensimbi ezishubhu ezishayelwa ekujuleni olwandle zinikeza izisekelo ezizinzile ezikwazi ukuthwala imithwalo esindayo evela emikhunjini, impahla, nezinto zokusebenza. Ukumelana nokugqwala kwazo namandla okuthwala imithwalo kuqinisekisa ukuphila isikhathi eside nokuphepha kwalezi ngqalasizinda ezibalulekile, ezibhekana nokuchayeka njalo emanzini anosawoti, amagagasi neziphepho.

Izingubo Ezikhethekile Nezinto Zokusebenza
Uma kubhekwa indawo yasolwandle enolaka, amashubhu ensimbi asetshenziswa phesheya kolwandle ngokuvamile afaka izimbotshana ezithuthukisiwe njenge-epoxy, i-polyurethane, noma i-zinc-based gavanization ukuze kuvinjelwe ukugqwala nokungcoliswa kolwandle. Kwezinye izimo, insimbi engagqwali noma ama-alloys ayi-duplex asetshenziselwa ukumelana okuthuthukisiwe kokugoba kanye nokuqhekeka kokugqwala kwengcindezi, ikakhulukazi emanzini ajulile noma ukusetshenziswa kwamanzi ajulile kakhulu.

Amashubhu ensimbi abalulekile ezimbonini zasolwandle nezisogwini, ahlinzeka ngamandla esakhiwo, ukuguquguquka, nokumelana nokugqwala okudingekayo ukuze kusebenze ngokuphepha ezindaweni eziyinselele. Ukusetshenziswa kwazo ekwakhiweni kwemikhumbi, ezinkundleni ezingasogwini, amapayipi angaphansi kolwandle, nengqalasizinda yasogwini kugqamisa ukuguquguquka nokuthembeka kwazo. Izinqubo ezintsha eziqhubekayo ekukhiqizweni kwensimbi, ukuthuthukiswa kwengxubevange, kanye nobuchwepheshe bokuvikela ziyaqhubeka nokuthuthukisa ukusebenza kwazo, zisekela imigomo yemboni yokuphepha, ukuqina, kanye nokuphathwa kwemvelo.
