CB/T425 Standard Marine Simplex Oil Filter Specification & Installation Tips
CB/T425 is the mainstream manufacturing standard for industrial and marine simplex oil filter, unifying size, pressure grade and connection parameters for global ship matching. Standard CB/T425 marine simplex oil filter covers full DN caliber range, adopts flange and threaded two connection ends to adapt different ship pipeline layouts. Its single-chamber integrated structure features low flow resistance, good oil circulation efficiency, applicable for marine diesel engine bypass lube oil filtration, cabin domestic oil pipeline and fire-resistant hydraulic oil filtration. The quick-opening upper cover simplifies daily disassembly, operators can take out and clean filter mesh without professional tools, lowering onboard maintenance difficulty. The valve body adopts anticorrosive cast iron raw material, fit for -10℃ to 80℃ marine oil working temperature, stable under normal ship operating pressure. For better service performance, engineers suggest installing simplex oil filter at horizontal pipeline position, avoiding reverse oil flow and regular weekly mesh cleaning. Standard sized simplex oil filters are stocked for fast delivery, widely purchased by ship repair yards, inland ship factories and small vessel operators for standardized onboard oil filtration renovation projects.
