Differential Pressure Flange

Description

Parameter / Process	Specification & Technical Highlights	Advantage / Value
Material	Grade 316 Stainless Steel (CF8M / 1.4408)	Superior pitting and corrosion resistance under aggressive fluid or industrial pipeline chemical environments.
Unit Weight	0.754 kg	Compact, high-density design optimized for space-saving fluid distribution networks.
Geometry Feature	Complex structure with Porous Blind Grooves	Advanced channel integration, ideal for multi-routing fluid control and compact hydraulic/pneumatic circuits.
Defect Control	Specialized shell-drying & Iron Inclusion Prevention	Defeats the industry challenge of difficult-to-dry deep cavities; advanced mold venting prevents subsurface iron inclusions or sand wash.
Casting Tolerance	ISO 8062 (GB/T6414) CT6 Grade	Precise near-net-shape accuracy, ensuring reliable bolt-hole centerlines and minimizing final CNC drilling offsets.
Surface Finish	Professional Sandblasting Treatment	Delivers a clean, matte, uniform surface finish while completely removing investment shell residues.

To ensure maximum structural integrity and blockages-free performance in high-precision fluid systems, we implement stringent final testing:

Blind Groove & Cavity Inspection: 100% video-endoscope or visual check to guarantee that all porous blind grooves are perfectly clean, smooth, and free of metallic inclusions or ceramic dust.
Dimensional Accuracy (CMM): Measured via Coordinate Measuring Machines to ensure absolute true position tolerances for all interlocking ports and blind holes.
Non-Destructive Testing (NDT): Processed via Liquid Penetrant Testing (LPT) to detect and eliminate any surface or corner micro-cracks before shipping.
Material Certification: Every batch is verified via Spectrometer for exact 316 chemical composition (with standard-compliant Chrome, Nickel, and Molybdenum levels).

Custom Fluid Circuitry: We custom-cast manifold blocks with varied internal routing, connection port sizes, and mounting hole layouts based on your 2D/3D drawings (STEP, IGES, DWG).
Optional Post-Processing: We offer secondary high-precision CNC thread tapping (NPT, BSP), passivation for advanced chemical protection, or electropolishing upon request.
Full Traceability: Material certificates and CMM inspection data sheets are provided standard with every delivery.
