What is ASTM B167?

ASTM B167 is the standard specification for seamless pipe and tube made from nickel-chromium-iron alloys and nickel-chromium-cobalt-molybdenum alloys. It is primarily used for general corrosion-resistant and heat-resistant applications in industries such as chemical processing, nuclear power, and aerospace.

 

What is ASTM B167 Inconel 600 Tubing?

ASTM B167 UNS N06600 seamless heat exchanger tubing is manufactured from a nickel-chromium-iron alloy. It is specifically designed for seamless pipe applications in high-temperature and highly corrosive environments, making it suitable for critical components such as heat exchangers, chemical processing equipment, steam generators, furnace tubes, and petrochemical installations.

 

Inconel 600 Seamless Heat Exchanger Tube Manufacturer

As a specialized supplier of nickel-based alloy tubing, GNEE offers ASTM B167 UNS N06600 seamless pipes with outer diameters ranging from 6 mm to 114 mm and wall thicknesses from 0.5 mm to 15 mm. Processing for UNS N06600 typically involves treatment at temperatures between 1800°F and 1900°F (980°C–1040°C), followed by rapid cooling or quenching. We support various production conditions including cold-drawn, annealed, and bright annealed and offer customized lengths and tolerance controls to meet specific design requirements.

The primary advantages of our Inconel 600 nickel-based alloy tubing lie in its exceptional resistance to high-temperature oxidation and corrosion. With a chromium (Cr) content of approximately 14%–17% and a nickel (Ni) content of at least 72%, the material maintains stable performance in environments involving high-temperature oxidation, carburization, and chloride exposure. Furthermore, it exhibits excellent resistance to stress corrosion cracking (SCC) and superior long-term thermal stability, making it suitable for high-temperature service conditions up to approximately 1100°C. Compared to standard stainless steel heat exchanger tubes, the seamless construction of ASTM B167 UNS N06600 tubing eliminates weld-related weak points, ensuring greater reliability under high-pressure cycling, thermal fluctuations, and corrosive media, thereby effectively reducing equipment downtime and maintenance costs.

Surface Protection	Each tube is individually wrapped in a Plastic Sleeve or thin PE film to prevent surface scratches and metal-to-metal friction during transit.
Bundling	For bulk shipments, tubes are bundled together using hexagonal nylon straps. To prevent surface damage, soft spacers or cardboard are used between the straps and the tubes.
Outer Packaging	Fumigated Wooden Cases (Plywood Boxes): We use reinforced, IPPC-standard wooden crates to prevent bending or crushing. The interior of the box is lined with waterproof paper.
Marking	Each tube is stenciled with: Brand, Alloy Grade (UNS N06600), Standard (ASTM B167), Heat Number, Size (OD x WT x L). The crate includes a detailed Packing List.

 

FAQ 

What is the difference between ASTM B167 and ASTM B163?

The main difference between ASTM B167 and ASTM B163 is their intended application and product scope: ASTM B167 covers general high-temperature and corrosive service for seamless pipes and tubes, while ASTM B163 is specifically tailored for seamless condenser and heat-exchanger tubes.

 

What is the maximum service temperature for Alloy 600?
In Oxidizing Atmospheres: Up to 1093°C (2000°F).
In Reducing Atmospheres (Sulfur-free): It performs very well, but if sulfur is present, the temperature limit drops significantly (usually below 500°C) due to the risk of sulfidation.

 

Can UNS N06600 piping be welded?
Yes. Common filler metals include Inconel 82 filler metal (ERNiCr-3) or 182 welding electrode (ENiCrFe-3). The weld area must be kept extremely clean; any oil, paint, or grease can cause "hot cracking" during the welding process. Post-weld heat treatment (PWHT) is generally not required.
