Low-Temperature Service: The primary purpose of ASME SA/A333 pipes is to provide reliable performance in low-temperature environments. These pipes are capable of withstanding temperatures as low as -50°F (-46°C).
Seamless and Welded Construction: The specification includes both seamless and welded pipe options, giving manufacturers and users flexibility in choosing the appropriate pipe type for their specific application.
Various Grades: ASME SA/A333 includes several different grades, such as Grade 1, Grade 3, Grade 4, Grade 6, Grade 7, Grade 8, Grade 9, Grade 10, Grade 11. Each grade has specific mechanical properties and chemical compositions to suit different temperature and pressure requirements.
Chemical Composition: The chemical composition of ASME SA/A333 pipes is carefully controlled to ensure excellent weldability and toughness at low temperatures. This includes specific limits on carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, and other alloying elements.
Testing and Inspection: The specification mandates various tests and inspections to ensure the quality and integrity of the pipes. Common tests include tensile tests, impact tests, hardness tests, and non-destructive testing (NDT) methods like ultrasonic testing and radiographic examination.
Compliance: To meet the ASME SA/A333 specification, manufacturers must adhere to strict quality control processes and ensure that the pipes meet the specified requirements.
ASME SA/A333 Pipe is a set of standards and specifications that govern the manufacturing and use of carbon and alloy steel pipes designed for low-temperature service. These pipes are crucial for industries requiring reliable performance in extreme cold conditions, and they are available in various grades and forms to suit different application requirements. Manufacturers and users must follow these standards to ensure the safety and functionality of these pipes in demanding environments.
A333 PIPE SPECIFICATIONS
A/SA333
NPS 1/4″ – 42″
Schedules 10 through 160, STD, XH and XXH
Scope
ASTM A333 covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
Material & Manufacture
The pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.
Heat Treatment Requirements
All seamless and welded pipe shall be treated to control their microstructure by the following methods: Normalizing per A 333/A 333M-05 section 4.3.1.1; section 4.3.1.2 or section 4.3.1.3 Quenched and Tempered per A 333/A 333M – 05 section 4.3.2.1 Double Normalized and Tempered per A 333/A 333M – 05 section 4.3.2.2

For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% would be permitted to a maximum of 1.35% manganese. When Grade 6 is ordered under this specification, supplying an alloy grade that specifically requires the addition of any element other than those listed for the ordered grade is not permitted. However, the addition of elements required for the deoxidation of the steel is permitted.
