Key Design Highlights
Anti - fatigue Structure
Control the uniformity of the shell wall thickness to reduce stress concentration.
The support structure is symmetrically distributed to improve stability under dynamic loads.
Sealing Reliability
The spring - energized seal, in combination with the precisely machined inner cavity, adapts to a temperature range of - 65°F to + 450°F.
The sealing surface roughness is ≤ Ra 1.6 μm, reducing the friction coefficient.
Maintainability Design
Marked areas for the replacement of vulnerable parts (e.g., the seal groove is reserved with maintenance space).
Modular assembly structure, supporting quick disassembly and assembly.
Quality Control and Inspection Standards
Manufacturing Specifications
The casting shall pass the X - ray flaw detection (ASTM E155 standard).
Dimensional full inspection shall be carried out after machining (calibrated by a three - coordinate measuring machine).
Surface Treatment Verification
Adhesion test of the chemical plating (ASTM B571 standard).
Corrosion resistance test (no red rust after a salt spray test of ≥ 96 hours).
Sealing Performance Test
Under a pressure of 250 PSI, hold the pressure for 30 minutes, and the leakage rate is ≤ 1×10⁻⁵ std cc/sec (tested with helium).
Application Scenarios Recommendation
Aerospace: Hydraulic pump shells, fuel system valve components.
Industrial Equipment: Servo motor shells, precision machine tool transmission devices.
Energy Sector: Sealing components of petroleum exploration equipment, hydraulic control units of nuclear power plants.
