Custom 316L Stainless Steel Flanged Spooled Pipes Production Process
The production of custom 316L stainless steel flanged spooled pipes involves several precise steps to ensure high quality, durability, and corrosion resistance. Below is a step-by-step breakdown of the process:
1. Material Selection & Inspection
Raw Material: 316L stainless steel pipes and flanges are sourced according to customer specifications.
Quality Check: The materials undergo chemical composition and mechanical property testing to ensure compliance with ASTM A312, A403, or other relevant standards.
2. Cutting & Preparation
Pipes are cut to length using band saws, plasma cutters, or laser cutters, ensuring precision.
Edge preparation is performed to ensure smooth welding and proper flange fitting.
3. Flange Attachment & Welding
Flange Positioning: Stainless steel flanges (e.g., slip-on, weld neck, lap joint, or blind) are aligned with the pipe ends.
Welding Process:
TIG (GTAW) or MIG (GMAW) welding is commonly used for superior corrosion resistance.
Full penetration welds are applied to ensure structural integrity.
If required, purging with argon gas is used to prevent oxidation inside the pipe.
4. Post-Weld Treatment
Pickling & Passivation: Removes weld discoloration and restores the protective chromium oxide layer.
Solution Annealing (if needed): Enhances corrosion resistance and mechanical properties.
5. Dimensional & Non-Destructive Testing (NDT)
Dimensional Inspection: Ensures pipe length, flange alignment, and tolerances are within specification.
Hydrostatic Testing: Pipes are tested under pressure to check for leaks.
X-ray (Radiographic) or Ultrasonic Testing: Detects internal weld defects.
Dye Penetrant Test (DPT): Identifies surface cracks.
6. Surface Finishing & Coating (Optional)
Bead blasting or mechanical polishing for a smooth finish.
Electropolishing for ultra-clean applications (e.g., food & pharma industries).
Epoxy or anti-corrosion coatings for harsh environments.
7. Marking & Documentation
Pipes are laser-etched or stamped with heat number, material grade, size, and standard compliance.
A mill test certificate (MTC) is provided for material traceability.
8. Packaging & Delivery
Flanged pipes are protected with plastic caps and packed using wooden crates or pallets for safe transportation.
If required, pipes are pre-assembled with gaskets and bolts for easier installation at the site.
