3. Manufacturing Process of Black Malleable Threaded Floor Flange Iron BSP Pipe Fittings Wall Mount 1/2" 3/4" 1"

Manufacturing Workflow: From sand casting to full-batch ISO-compliant QC

Key Points in Manufacturing:

Raw Material: Only high-grade ferritic malleable iron is selected for optimal ductility and tensile strength (>350 MPa).
Sand Casting: Advanced molding lines ensure wall uniformity and flaw minimization.
Annealing: Prolonged at 950°C per ISO 5922, transforms white cast iron into malleable state — grain refinement enhances corrosion resistance.
CNC Machining: Critical dimensions (thread ID, flange face) are final-shaped for high fit tolerance (H7/g6, typically +0.02mm).
BSP Threading: Strict adherence to ISO 7/1 standard and gauges tested for leakproof fit.
Inspection: Each batch is pressure tested (1.6MPa, 48h), surface-checked (ASTM B117), and marked for traceability per EN 10204 3.1.
Surface Finish: Phosphating & Protective Oil ensures >500h salt spray resistance (lab tested to ASTM B117).

Machining and precision threading process - ensuring all black Malleable Threaded Floor Flange Iron BSP Pipe Fittings Wall Mount 1/2" 3/4" 1" meet ISO/ANSI standards.

4. Technical Advantages & Industry Standards

Corrosion Resistance: Phosphated black spheroidal iron outperforms galvanized in long-term humidity cycles (25% higher resistance in salt-spray tests, ASTM B117).
