Product Specification

ASTM A672 A50 Welded Steel Tube Electric-Fusion-Welded Steel Pipe For High-Pressure Service At Moderate Temperatures

Material and Specification

ASTM A672 is a standard specification for electric-fusion-welded steel pipe suitable for high-pressure service at moderate temperatures. This specification covers steel pipe with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels. The pipes are made by electric fusion welding and are intended for use in high-pressure applications such as petrochemical plants, power plants, and refineries.

Key Features

• Electric-fusion-welded construction: The ASTM A672 pipes are manufactured using the electric fusion welding process, which ensures a strong and reliable bond between the steel plates.
• High-pressure service: These pipes are designed to withstand high-pressure conditions, making them suitable for applications where the transportation of fluids or gases under pressure is required.
• Moderate temperature resistance: The ASTM A672 pipes are capable of operating at moderate temperatures, making them suitable for a wide range of industrial applications.
• Durable and long-lasting: The use of high-quality steel and the electric fusion welding process ensures that these pipes have excellent durability and a long service life.

Mechanical Properties

Steel Grade

The ASTM A672 specification includes several steel grades, namely A45, A50, A55, B55, and B60. These grades indicate the minimum yield strength of the pipes and their corresponding tensile strength. The higher the grade, the stronger the pipe.

Application

ASTM A672A45, A50, A55, B55, B60 welded steel tubes are widely used in various industries for high-pressure applications at moderate temperatures. Some common applications include:

1. Petrochemical plants: These pipes are used for transporting various fluids and gases in petrochemical processing units.
2. Power plants: The pipes are utilized for conveying steam and other fluids in power generation facilities.
3. Refineries: ASTM A672 pipes find application in refineries for the transportation of oil, gas, and other petroleum products.
4. Chemical plants: These pipes are suitable for conveying chemicals and corrosive substances in chemical processing plants.

Possible Alternative Grades

While ASTM A672A45, A50, A55, B55, B60 are commonly used grades, there are alternative specifications available depending on specific requirements. Some possible alternative grades include ASTM A691 and API 5L, which offer similar characteristics and are suitable for high-pressure applications at moderate temperatures. However, it is essential to consult the relevant standards and specifications to determine the most appropriate alternative grade for a particular application.
