Fitting Manufacturing Workflow

High-Quality Fitting Solutions for Plumbing and HVAC Systems
  1. Raw Material Inspection (Key Node)
    High-grade billets (carbon, stainless, or alloy steel) are tested for composition and compliance (ASTM/EU standards).
  2. Primary Forming
    Casting, forging, or CNC turning converts billets into basic fitting shapes.
  3. Machining & Threading
    Computerized lathes and multi-axis milling achieve ISO tolerances of ±0.01mm.
  4. Heat Treatment (Critical)
    Improves tensile strength and corrosion resistance (normalizing/isothermal annealing processes).
  5. Surface Treatment & Coating
    Sandblasting, pickling, & coatings (e.g. epoxy/PVC) meet ISO 11124-2, extending Fitting longevity.
  6. Quality Inspection & NDE (Non-Destructive Evaluation, Key Node)
    Hydrostatic tests, X-ray, ultrasonic, and dimension checks per ISO 9001/ANSI B16.9 standards.
  7. Packing & Delivery
    Anti-rust packing, marking traceability codes, and shipment.

This meticulous workflow ensures that every Fitting meets or exceeds global project requirements for longevity and safety.
