Piv txwv li, cov tshuab hluav taws xob tua hluav taws hauv cov khw muag khoom, tsev kho mob thiab lwm qhov chaw yog welded nrog galvanized steel kav los xyuas kom meej cov dej ruaj khov thaum muaj xwm txheej ceev.
V. Shipbuilding thiab Marine Engineering
Marine Piping Systems
Scene: Seawater txias, roj tsheb thauj mus los, thiab lwm yam, yuav tsum tau tiv thaiv kev co, corrosion.
Piv txwv li, marine mainframe roj pipelines siv tooj liab -nickel alloy welded fittings los tiv thaiv seawater corrosion.
LNG cargo bay kav yog welded nrog txias steel fittings (xws li . 9% npib tsib xee steel) kom haum raws li qhov qis li -163℃.
Subsea Pipelines
Scene: Sib sib zog nqus siab, tsis tshua muaj kub, siab corrosive ib puag ncig.
Piv txwv li, North Sea Subsea pipelines siv bimetallic composite welded yeeb nkab fittings (sab hauv stainless hlau + sab nrauv carbon steel) kom sib npaug corrosion kuj thiab lub zog.
VI. INTRODUCTION Khoom noj khoom haus thiab dej haus kev lag luam
Ntxuav Piping Systems
Qhov xwm txheej: Kev thauj mus los yuav tsum muaj kev tiv thaiv los ntawm cov kab mob xws li mis nyuj thiab npias.
Piv txwv li, cov kav dej hauv lub brewery lub saccharification Rhiav yog welded nrog 304 stainless hlau socket, thiab cov phab ntsa sab hauv yog polished rau ra tsawg dua los yog sib npaug li 0.8 μm los tiv thaiv kab mob adhesion.
