3. Manufacturing Process of Fittings

The production of high-performance Fittings—such as those at JRain FRP—features rigorous controls for material integrity, precision machining, and extensive end-product testing. Below is the typical manufacturing workflow for advanced Fittings:

  1. Raw Material Selection
    High-purity resin, fiberglass mats (for FRP), or quality steel rounds/billets (metal fittings) are sourced from certified suppliers.
  2. Cutting & Pre-forming
    Materials cut to size according to CAD/CAM-derived specifications.
  3. Primary Forming
    FRP Fittings: Filament winding, compression molding, and hand layup.
    Metal Fittings: Forging, hot-press forming, or CNC machining.
  4. Curing/Heat Treatment
    Resin cure (FRP, typically at 60–90°C), or annealing/normalizing (steel) to enhance properties.
  5. Dimensional Machining
    Precision machining (CNC, turning, drilling) to tight tolerances (ISO 2768-mK; ±0.1mm typical).
  6. Surface Treatment
    Sanding and resin coating (FRP); pickling, passivation, or anti-corrosive coating (metals).
  7. Full Inspection
    All products pass tests: hydrostatic, ultrasonic, and dimensional—per standards (ISO 14692, ASTM D2996, ASME B16.9).
  8. Packing & Traceability
    Final Fittings are labeled for traceability, packed per ISO 9001, and shipped for deployment.

8. Fittings Industry FAQ
Professional FAQ
Q1: What are the standard materials used for Fittings in process piping?
Fittings are widely available in materials like FRP (Fiberglass Reinforced Plastic), stainless steel (SS304/316), carbon steel, and advanced polymers (PVC, CPVC, PVDF). Material selection depends on temperature, pressure, corrosion, and regulatory standards.
Q2: What is the difference between Schedule 40 and Schedule 80 Fittings?
Pipe schedule indicates wall thickness, affecting pressure rating. Schedule 80 Fittings have thicker walls and are rated for higher pressure than Schedule 40, often used in industrial/chemical conveyance or high-pressure water systems.
Q3: Which international certifications should quality Fittings meet?
Leading Fittings adhere to ISO 14692 (FRP), ASTM D2996/2467, ASME B16.9 (metal), ANSI, NSF/ANSI 61 (water safety), and sometimes FDA or EN standards for food/pharma usage.
Q4: What non-destructive testing (NDT) is applied to industrial Fittings?
Hydrostatic pressure testing, ultrasonic thickness, visual inspection, and sometimes radiography or dye penetrant (for welds)—guarantee safety and compliance before shipment.
Q5: How is field installation of Fittings assured for leak-free operation?
Fittings must be installed using ISO or ASME-approved torque, sealing (PTFE, gaskets), and alignment guidelines. Some FRP Fittings require adhesive bonding and curing under controlled environmental conditions.
Q6: What is the typical delivery time for custom Fittings?
Standard Fittings: 7–14 days. Custom/engineered Fittings: 4–6 weeks, depending on scope and design approval.
Q7: What is the service life and warranty for your Fittings?
FRP Fittings from leading manufacturers offer 20–30 years of service life backed with 2 or 5-year warranty options and 24/7 technical support.
