ASTM B167 Inconel 690 Nickel Chromium Iron Alloys Seamless Steel Pipe For Steam Generator

Material and Specification

The ASTM B167 specification covers nickel-chromium-iron alloys (Inconel 690) in the form of seamless steel pipes specifically designed for steam generator applications. These pipes are manufactured using high-quality materials and adhere to the strict standards set by ASTM International.

Key Features

The Inconel 690 seamless steel pipes exhibit several key features that make them ideal for steam generator applications:

1. High Temperature Resistance: Inconel 690 offers exceptional resistance to high temperatures, making it suitable for use in steam generators where heat and pressure are involved.

2. Corrosion Resistance: These pipes possess excellent resistance to corrosion, including oxidation and scaling, which is crucial for maintaining the integrity and longevity of steam generators.

3. Strength and Durability: Inconel 690 seamless steel pipes have high strength and durability, allowing them to withstand the demanding conditions of steam generator environments.

4. Seamless Construction: The seamless design of these pipes ensures a smooth and uninterrupted flow of steam, minimizing the risk of leaks and enhancing overall efficiency.

Mechanical Properties

The mechanical properties of Inconel 690 seamless steel pipes are as follows:

Steel Grade

Inconel 690 is the designated steel grade for these seamless steel pipes, as per the ASTM B167 specification.

Application

The ASTM B167 Inconel 690 seamless steel pipes find extensive application in steam generator systems. They are specifically designed to handle the high temperatures, pressures, and corrosive environments encountered in steam generation processes. These pipes are used for conveying steam within the generator, ensuring efficient and reliable operation.

Possible Alternative Grades

While Inconel 690 is a highly suitable material for steam generator applications, there are alternative grades that can be considered based on specific requirements. Some possible alternative grades include Inconel 601, Inconel 617, and Inconel 625. These alloys offer similar high-temperature and corrosion resistance properties, but their selection should be based on the specific needs and operating conditions of the steam generator system.
