Our Alloy 625 Seamless/Welded Pipe Schedule 80 is engineered to withstand extreme environments, offering superior corrosion resistance, high-temperature strength, and versatile shaping options. Whether you need round, square, or rectangular profiles, this product delivers reliability for demanding applications in chemical processing, marine engineering, aerospace, and oil & gas industries.
Key Features & Technical Specifications
- Material Excellence: Made from Alloy 625 (UNS N06625), a nickel-chromium-molybdenum superalloy known for outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking.
- Dual Manufacturing Options: Available in seamless or welded construction. Seamless provides uniform strength; welded offers cost efficiency for large-diameter applications.
- Schedule 80 Wall Thickness: Designed for high-pressure systems, with thicker walls compared to standard schedules, ensuring structural integrity under extreme conditions.
- Multiple Cross-Sectional Shapes: Round, square, and rectangular forms available to meet diverse structural and fluid-handling requirements.
- High-Temperature Stability: Operates effectively from cryogenic temperatures up to 980°C (1800°F), maintaining oxidation resistance and mechanical strength.
- Excellent Formability & Weldability: Can be easily fabricated, welded, and machined, reducing installation complexity and cost.
- Customizable Dimensions: Lengths, wall thickness variations, and surface finishes (annealed, pickled, polished) are available upon request.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between seamless and welded Alloy 625 pipe?
A: Seamless pipe is manufactured without a weld seam, offering uniform strength and pressure resistance. Welded pipe is formed by rolling and welding a plate, which can be more cost-effective for larger diameters. Both options are available in Schedule 80. -
Q: Can you supply square or rectangular tubes in Schedule 80 thickness?
A: Yes, we produce round, square, and rectangular profiles in Alloy 625 with Schedule 80 wall thickness. Custom sizes are available upon request. -
Q: What are the typical lead times for an order?
A: Lead times vary by quantity and specifications. For standard sizes, delivery is typically 2–4 weeks. Custom orders may require 4–6 weeks. We ship from multiple Chinese ports to optimize logistics. -
Q: Does this pipe meet NACE standards for sour service?
A: Alloy 625 is inherently resistant to sulfide stress cracking and is often used in sour service. We can provide material test certificates and confirm compliance with relevant NACE MR0175/ISO 15156 if required. -
Q: What certifications do you provide with the shipment?
A: We provide Mill Test Certificates (MTC) per EN 10204 3.1 or 3.2, as well as certificates for ISO, HACCP, and other quality systems. Third-party inspection is also available upon request. -
Q: Can you cut the pipe to specific lengths or add custom end preparations?
A: Yes, we offer cutting to length, beveling, threading, and other end preparations. Please specify your requirements when ordering. -
Q: What is the minimum order quantity (MOQ) for this product?
A: MOQ depends on size and shape. Generally, for standard round pipes, MOQ is 500 kg. For custom shapes, MOQ may be higher. Contact us for details. -
Q: How do you ensure the quality of the pipes?
A: We follow strict quality control procedures from raw material inspection to final testing. Each batch undergoes hydrostatic testing, eddy current testing, dimensional checks, and chemical analysis as per ASTM standards.
