Custom N06625 Nickel Alloy Pipe Spools
As a professional nickel alloy pipe spools supplier, we produce high quality custom N06625 nickel alloy pipe spools.
The alloy grade UNS N06625 ( also called INCONEL 625) is a high performance nickel alloy. It adds molybdenum and more chromium than nickel alloy 600. This gives it better corrosion resistance.
At the same time, N06625 added niobium to increase the effect of solid solution strengthening. This gives it more strength.
We manufacture N06625 pipe spool strictly according to ASTM standard. N06625 has high strength, which makes the cold rolling process of pipe tube more difficult.
Our factories and fabrication facilities are filled with highly skilled craftsmen, pipe fitters, pipe fabricators, pipe welders with excellent safety and quality performance records. We take great pride in not only meeting, but exceeding our customers’ expectations in all areas, including performance, design, logistics, schedule, delivery and cost.

Custom N06625 Nickel Alloy Pipe Spools Applications & Usages
N06625 pipe spool is highly resistant to halide-rich environments, thanks to its nickel-based composition, which effectively withstands halogen-induced corrosion. This exceptional resistance has made Alloy 625 a top choice for refuse boiler applications, where durability under extreme conditions is critical.
Beyond industrial waste environments, 625 seamless pipe is an outstanding material for marine applications. Its high nickel content offers superior resistance to chloride-induced stress corrosion cracking, while its impressive tensile strength and immunity to pitting and crevice corrosion ensure long-term performance in seawater exposure.
In addition to its excellent mechanical properties, Alloy 625 boasts high tensile, creep, and rupture strength, coupled with outstanding weldability. These attributes make it a preferred material in aerospace engineering, where it is commonly used in ducting and exhaust systems and components.
Custom N06625 Nickel Alloy Pipe Spools Production Process
The production of custom 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: pipes and fittings are sourced according to customer specifications.
Quality Check: The materials undergo chemical composition and mechanical property testing to ensure compliance with ASTM, 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.

Features of Custom N06625 Nickel Alloy Pipe Spools
The 625 alloy has excellent corrosion resistance due to its highly alloyed composition. It is almost not corroded in common mild environments, such as the atmosphere, fresh water, sea water, neutral salt solutions and alkaline media.
In more corrosive environments, the synergistic effect of nickel and chromium gives alloy 625 its resistance to oxidizing chemicals.
High levels of nickel and molybdenum increase resistance to non-oxidizing environments. The high molybdenum content also gives the alloy excellent resistance to pitting and crevice corrosion. The presence of niobium can stabilize the alloy to a certain extent and avoid intergranular cracks.
