Manufacturing Process Flow of Advanced NG Equipment

The production of high-integrity NG equipment like the RTZ1-/0.4RQ series involves a meticulous multi-stage process, integrating advanced engineering with rigorous quality control. This ensures each unit meets the stringent performance and safety criteria demanded by industry standards.

  1. Material Selection & Sourcing: High-grade materials are chosen based on application requirements, including specific grades of ductile iron or cast steel for main housings (ensuring corrosion resistance and structural integrity), and stainless steel for internal components like valve seats and springs (for precision and durability). Elastomers (e.g., NBR, Viton) are selected for diaphragms and seals based on gas compatibility and temperature range, adhering to standards like ASTM.
  2. Casting/Forging: For larger, high-pressure components, casting processes (e.g., sand casting for ductile iron) or forging (for specialized steel parts) are employed to create the initial shapes of the body and cover. These processes are strictly controlled to minimize defects and ensure material integrity.
  3. CNC Machining: Precision machining is critical. Multi-axis CNC machines are used to achieve tight tolerances for internal passages, valve seats, and connection points. This stage ensures the dimensional accuracy necessary for optimal sealing, flow characteristics, and compatibility with other components.
  4. Surface Treatment & Coating: Components may undergo surface treatments such as passivation for stainless steel, or protective coatings (e.g., epoxy paint, galvanization) for cast iron parts, to enhance corrosion resistance and extend service life, particularly in outdoor or corrosive environments.
  5. Assembly: Skilled technicians assemble the various components, including diaphragms, springs, valve plugs, and sensing lines. This stage often involves cleanroom environments for critical parts to prevent contamination.
  6. Testing & Calibration: Each regulator undergoes rigorous testing:
    • Hydrostatic Pressure Test: To verify body integrity at elevated pressures, conforming to standards like ANSI B16.34.
    • Leakage Test: Using air or nitrogen, often with submerged testing, to detect any leaks from the body, seat, or seals, meeting requirements like ISO 5208.
    • Functional Test & Calibration: Each unit is tested under simulated operating conditions to verify outlet pressure accuracy, set-point stability, lock-up performance, and response time, ensuring it adheres to specifications like EN 334.
  7. Final Inspection & Packaging: A final visual and quality inspection ensures no defects are present. Products are then carefully packaged for shipment, with appropriate protective measures.

This comprehensive process ensures a service life often exceeding 20 years with proper maintenance, making these regulators suitable for target industries such as petrochemical, metallurgy, and industrial gas distribution (which impacts even sectors like water supply & drainage indirectly via energy needs).
