ISO CertifiedSGS CertifiedTUV Certified MSME Certified

Super Duplex 2507 Pipe is a high-performance stainless steel pipe known for its exceptional strength and corrosion resistance. Manufactured from a duplex stainless steel alloy containing roughly 25% chromium and 7% nickel, this material offers superior resistance to chloride-induced stress corrosion cracking and pitting. Its balanced microstructure of austenite and ferrite phases provides enhanced mechanical properties, making it ideal for demanding industrial environments.

These pipes are primarily used in sectors such as oil and gas, chemical processing, and marine applications, where exposure to harsh chemicals and saline conditions is common. The alloy’s ability to withstand extreme temperatures and aggressive media ensures reliability in pipelines, heat exchangers, and pressure vessels. The product's robust performance supports long service life and reduces maintenance costs, which is critical for industrial operators aiming to maximize uptime.

Manufactured according to international standards like ASTM A790 and EN 10216, these pipes meet stringent quality and dimensional requirements. They are available in various diameters and thicknesses to suit specific project needs, with precise control over mechanical properties such as tensile strength and yield strength. The pipes undergo rigorous testing, including ultrasonic and hydrostatic tests, to guarantee integrity and performance under pressure.

Export-ready Super Duplex 2507 pipes are supplied with comprehensive documentation, including mill test certificates and traceability reports, ensuring compliance with global trade regulations. Packaging is designed to protect the pipes during transit, minimizing the risk of damage. This makes them a reliable choice for international buyers seeking durable and corrosion-resistant piping solutions for critical infrastructure projects.

Manufacturing Process & Heat Treatment of Super Duplex 2507 Pipe

Annealing

Annealing of Super Duplex 2507 pipe is performed at temperatures between 1020°C and 1100°C. This process is essential for relieving internal stresses and ensuring uniform microstructure, which enhances ductility and toughness. The material is held at the target temperature for a specified duration before being cooled rapidly to room temperature, typically in air.

Forging

The forging of Super Duplex 2507 involves heating the material to a temperature range of 1100°C to 1200°C, allowing for significant deformation. This process improves the mechanical properties by refining the grain structure and enhancing strength. The forged pipes are then cooled down gradually to room temperature to minimize residual stresses.

Hardening & Tempering

Process Temperature Range (°C) Quenching Medium Purpose
Hardening 1000 - 1100 Oil To increase hardness and strength
Tempering 600 - 800 Air To reduce brittleness and improve toughness
Stress Relieving 300 - 500 Air To relieve residual stresses from manufacturing

The heat treatment processes of Super Duplex 2507 pipe are critical in achieving the desired mechanical properties, ensuring that the pipes meet the rigorous demands of various industrial applications, particularly in corrosive environments.
