HNEENERGY ASME A672 Carbon Seamless And Welded Pipes Round Stainless Steel Pipe

ASME A672 pipes are a range of electric-fusion-welded (EFW) steel pipes used primarily for atmospheric and lower temperatures. This specification covers steel pipe for high-pressure service at moderate temperatures. Here's a detailed overview of the ASME A672 specification:

General Properties
Manufacturing Process: Electric fusion welded (EFW), where the weld is made by heating the material with an electric arc. This method is especially suitable for large diameter pipes.
Material: The pipes are made from pressure vessel quality plate of several analyses and strength levels.
Welding: The pipes are available in full or partial joint penetration welds, depending on the requirements.
Classifications
ASME A672 pipes are categorized based on the type of plate material and the heat treatment performed:

Class Designation: Classifies pipes according to the type of heat treatment they undergo, such as full or partial annealing, normalizing, normalizing and tempering, or quenching and tempering. Examples include classes 10, 20, 30, etc., with each having distinct properties and applications.
Type of Steel: Can range from simple carbon steel to complex alloy steel, classified under different grades such as CA55, CB60, CB65, CB70, etc. Each grade specifies a different type of plate material used.
Chemical and Mechanical Requirements
Chemical Composition: The specification includes detailed requirements for the chemical composition of the plate material, ensuring the pipe meets necessary durability and performance standards.
Mechanical Properties: Includes requirements for tensile strength, yield strength, and elongation based on the grade of steel and heat treatment.
Applications
Utility Services: Commonly used in applications such as transporting water, oil, and natural gas at lower temperatures compared to their counterpart specifications which handle higher temperatures.
Structural Applications: Due to their robust mechanical properties, these pipes are also suitable for structural purposes in buildings, bridges, and other infrastructures.
Pressure Applications: Often used in pressure vessels and boiler installations where moderate temperatures are involved.
Quality Assurance
Testing: Pipes undergo several tests, including hydrostatic testing, mechanical tests like tensile and hardness tests, and non-destructive electric tests, to ensure quality and performance under specified conditions.
Certification: Pipes come with certifications that guarantee the material and fabrication meet the standards specified.
ASME A672 pipes are crucial in various industrial applications due to their ability to withstand moderate temperatures and high pressure, providing a reliable solution for lower temperature services with excellent durability and safety.
