High - pressure Sealing Design
Working Pressure: Usually 600 - 1200 psi (4.1 - 8.3 MPa), and in some special working conditions, it can reach 1500 psi (10.3 MPa).
Sealing Methods: Double O - ring Sealing (EPDM/FKM materials, resistant to chemical corrosion), Metal - Conical Surface Sealing (suitable for ultra - high - pressure working conditions), Flat Surface Sealing + Gaskets (PTFE/graphite gaskets, high - temperature resistant).
Machining Precision of Sealing Surface: Surface roughness Ra ≤ 0.8 μm (mirror polishing), flatness ≤ 0.05 mm.Precision Machining Process
CNC Lathe Machining: Ensure high precision of the flange end face and bolt holes.
Electropolishing (EP): Improve corrosion resistance and reduce the risk of surface adhesion (commonly used in the food/medical industry).
Laser Marking: Permanently mark information such as material and pressure rating.Structural Optimization Design
Reinforcing Rib Design: Increase the flange stiffness and prevent deformation under high pressure.
Flow Channel Optimization: Reduce turbulence and pressure loss (suitable for high - flow systems).
Quick - release Structure: Some models support quick disassembly for easy maintenance.
