Product Description
Flange Usage Instructions:
1. Inspect– Check for damage, corrosion, or deformities before installation.
2. Align – Position the flange correctly, ensuring bolt holes match the connecting pipe or equipment.
3. Gasket Insertion– Place a suitable gasket between flanges to prevent leaks.
4. Bolt Tightening – Insert and tighten bolts evenly in a crisscross pattern to ensure uniform pressure.
5. Pressure Test– Conduct a leak test (hydrostatic/pneumatic) before full operation.
6. Maintenance – Regularly check bolts and gaskets for wear or loosening.

Flange Manufacturing Process
1. Flange Manufacturing Process (Brief Description)Material Selection – Choose raw materials (carbon steel, stainless steel, etc.) based on standards like ASTM or DIN.
2. Cutting & Shaping – Cut metal plates or bars, then forge or machine into rough flange shapes.
3. Heat Treatment – Annealing or quenching to enhance strength and durability.
4. Machining – Precision CNC/lathe machining for bolt holes, sealing surfaces, and dimensional accuracy.
5. Surface Treatment – Apply coatings (galvanizing, painting) or polishing for corrosion resistance.
6. Quality Inspection – Check dimensions, pressure rating, and defects (UT/RT testing if required).
7. Marking & Packaging – Stamp with standard markings (size, material, pressure class) and pack for shipment.
