Qhov zoo tshaj plaws ntawm LSAW (Laminated Steel Wire Arrangement) cov kav dej yog nyob rau hauv lawv cov kev ua haujlwm zoo tshaj plaws thiab cov khoom siv tshuab, tso lub hauv paus rau kev nyab xeeb ntawm kev thauj mus los roj thiab roj. LSAW pipelines yog tsim los ntawm dov steel daim hlau thiab ces welding lawv nrog ib tug ncaj longitudinal seam. Cov qauv no ua kom muaj kev sib txawv ntawm kev ntxhov siab ntau dua thaum lub raj xa dej raug rau sab hauv. Muab piv rau cov kauv welded ntawm kauv welded kav, txoj hlua ncaj nraim zam qhov teeb meem kev ntxhov siab vim los ntawm lub kaum sab xis ntawm lub vuam thiab cov kav dej, txo qhov kev pheej hmoo ntawm vuam tawg thaum lub sij hawm siab - kev thauj mus los. Tsis tas li ntawd, LSAW pipelines yog tsim los siv siab - zoo, tuab steel phaj ua raw khoom. Cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm cov hlau phaj no ruaj khov dua. Ua ke nrog daim ntawv thov paub tab ntawm submerged arc vuam thev naus laus zis, qhov vuam zoo yog yooj yim los tswj, thiab lub zog thiab tawv ntawm cov pob qij txha welded tau ntsib lossis ntau tshaj cov qauv ntawm cov khoom siv hauv paus. Thaum lub sij hawm cov roj thiab roj tsheb thauj mus los, tshwj xeeb tshaj yog nyob rau hauv hnyav tej yam kev mob xws li kev kub siab thiab tsis kub, LSAW pipelines tau zoo tiv thaiv corrosion thiab siab poob siab ntawm cov roj thiab cov pa tawm xov xwm, txo qhov tshwm sim ntawm kev nyab xeeb xwm txheej xws li xau thiab cov yeeb nkab tawg, thiab ua kom muaj kev ruaj ntseg ntawm kev thauj mus los ntawm roj thiab roj.
Kev hloov pauv mus rau cov kab loj loj thiab kev kub ntxhov yog qhov zoo ntawm LSAW pipelines nyob rau hauv qhov ntev -cov roj thiab roj tsheb thauj mus los. Raws li kev txhim kho cov roj thiab roj thoob ntiaj teb txuas mus rau cov dej sib sib zog nqus thiab cov chaw nyob deb, qhov kev thov ntev - nrug, siab - ntws- tus nqi roj thiab roj tsheb thauj mus los tau nce ntxiv, ua rau qhov xav tau siab dua ntawm cov kav xa dej thiab qhov ntsuas siab. LSAW cov kav dej tuaj yeem tsim tau hauv cov kab loj dua, uas ua rau muaj kev sib txhuam zoo thaum lub sijhawm thauj mus los, nce tus nqi ntws, thiab txo cov chaw pabcuam xws li cov twj tso kua mis thiab chaw nres tsheb compressor, yog li txo qis kev tsim kho thiab kev khiav haujlwm ntawm tag nrho cov kev thauj mus los. Tsis tas li ntawd, LSAW cov kav dej muaj qhov ntsuas siab, ua tau raws li qhov xav tau ntawm siab - cov roj thiab roj tsheb thauj mus los thiab tsim nyog rau siab - siab xws li ntev - cov kav xa hluav taws xob thiab cov kav dej roj av.
Kev tsim cov txheej txheem ntawm LSAW cov kav dej yog qhov paub tab, ua haujlwm txuas ntxiv dov thiab ncaj- seam submerged arc vuam, ua rau muaj kev ua haujlwm siab thiab ua kom loj - nplai ntau lawm. Loj - nplai ntau lawm tsis tsuas yog txo cov nqi tsim khoom tab sis kuj ua kom cov khoom zoo ib yam. Piv rau seamless steel kav, LSAW pipelines siv steel daim hlau raws li raw cov ntaub ntawv, uas ua rau tus nqi ntawm raw cov ntaub ntawv raw khoom thiab ib tug yooj yim txheej txheem ntau lawm, txo lub zog noj thiab cov khoom pov tseg thaum lub sij hawm tsim khoom. Tsis tas li ntawd, LSAW pipelines siv submerged arc vuam, uas muaj cov vuam ceev ceev, ruaj khov weld zoo, thiab cov nqi qis tom qab kuaj thiab kho. Tsis tas li ntawd, LSAW pipelines muaj lub neej ua haujlwm ntev dua; lawv cov kev tiv thaiv corrosion thiab cov qauv kev ruaj ntseg txo qhov zaus ntawm kev saib xyuas thiab hloov, txo cov nqi txij nkawm thiab txhim kho kev lag luam ntawm cov roj thiab cov roj tsheb thauj mus los.
Zoo corrosion kuj thiab ib puag ncig adaptability yog qhov tseem ceeb rau kev ruaj ntseg ntawm LSAW pipelines nyob rau hauv complex roj thiab roj tsheb thauj mus los ib puag ncig. Cov roj thiab cov pa hluav taws xob feem ntau muaj cov khoom corrosive xws li hydrogen sulfide, carbon dioxide, thiab dej, thiab cov kav dej roj thiab roj feem ntau yuav tsum tau taug kev nyuaj geological thiab climatic ib puag ncig xws li suab puam, Gobi, dej hiav txwv, thiab permafrost, ua rau muaj teeb meem loj rau cov kav dej corrosion thiab ib puag ncig adaptability. LSAW pipelines tuaj yeem siv ntau yam kev tiv thaiv kev tiv thaiv- kev kho corrosion thaum lub sij hawm tsim khoom, xws li sab nraud los tiv thaiv - corrosion coatings (3PE, FBE, thiab lwm yam), sab hauv los tiv thaiv-corrosion coatings, thiab cathodic tiv thaiv, zoo tiv thaiv ntau yam corrosion, nrog rau cov av corrosion, seawater corrosion, thiab roj thiab gas media corrosion. Tsis tas li ntawd, cov hlau phaj siv nyob rau hauv LSAW pipelines tau txais kev tswj xyuas zoo, muaj qhov zoo heev uas tsis tshua muaj -kub toughness thiab qaug zog tiv thaiv, ua rau lawv tiv taus qhov qis- qhov kub thiab txias ib puag ncig ntawm thaj chaw txias thiab qhov cuam tshuam ntawm geological kev puas tsuaj xws li av qeeg thiab tawg. Nyob rau hauv ib puag ncig nyuaj xws li marine roj thiab roj tsheb thauj mus los thiab suab puam roj thiab roj tsheb thauj mus los, LSAW cov kav dej tuaj yeem ua haujlwm ruaj khov, txo cov kav dej tsis ua haujlwm los ntawm ib puag ncig thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha kev thauj mus los ntawm cov roj thiab roj.
