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.
For any information related to ASTM A333 Carbon And Alloy Steel Pipe, please contact HYT at mail: [email protected] with your inquiry.
The ASTM A333 standard covers carbon and alloy steel pipes manufactured by both seamless and Electric Resistance Welded (ERW) methods, specifying that the pipes must be produced through either process without the addition of filler metal during the welding operation.
There are total 9 grades in this standard, Grade 1, 3, 4, 6, 7, 8, 9, 10 and Grade 11.
There are differences on chemical composition and mechanical properties as following table:

Octagonal Pipe
HYT specializes in two primary steel pipe manufacturing techniques: seamless and welded. Each method offers unique manufacturing processes and applications, ensuring we can meet the diverse needs of various industries.
Seamless Steel Pipes
Seamless steel pipes are manufactured through processes such as hot rolling, cold rolling, or cold drawing. These methods start with a solid steel billet, heated and formed under high temperature and pressure to create a tube without any welded seams. The main advantages of seamless pipes lie in their uniformity and strength, making them ideal for high-pressure, high-temperature environments, or other demanding conditions. Due to their seamless nature, these pipes exhibit higher integrity and resistance to cracking under internal and external pressures.
Welded Steel Pipes
In contrast to seamless pipes, welded steel pipes are produced through methods like Electric Resistance Welding (ERW), Submerged Arc Welding (SSAW), or Longitudinal Submerged Arc Welding (LSAW). These processes involve curling steel sheets or coils into a tubular shape and welding them at the seam. The advantages of welded pipes include cost-effectiveness and the ability to manufacture large diameters and thick-walled pipes, crucial for many structural and transportation applications.
