ASTM A311 Seamless Steel Tube Cold-Drawn Stress-Relieved Carbon Steel Tube for Pipeline

Material

ASTM A311 is a specification for seamless cold-drawn stress-relieved carbon steel tubes, primarily used in the manufacturing of pipelines. These tubes are designed to withstand high pressures and are often utilized in various industrial applications, including oil and gas, chemical processing, and structural applications.

Specification

The ASTM A311 specification outlines the requirements for seamless carbon steel tubes that are cold drawn and stress relieved. The tubes must meet specific mechanical properties and chemical composition standards to ensure their performance in demanding environments.

Key Features

• Seamless Construction: Provides uniform strength and eliminates weak points.
• Cold-Drawn: Enhances dimensional accuracy and surface finish.
• Stress-Relieved: Reduces internal stresses, improving the tube's performance under load.
• High Strength: Suitable for high-pressure applications.
• Versatile Applications: Can be used in various industries, including oil and gas, automotive, and construction.
