ASTM A53 Seamless Pipes

Description

Seamless steel pipes are manufactured from a single solid steel round billet, pierced and rolled into a hollow tube. This process eliminates any seam or weld, resulting in a high-pressure resistant pipe suitable for demanding applications.

Standards and Grades:

• ASTM A53 – Welded and Seamless Steel Pipe

Sizes:

• Nominal Diameter (NPS): Ranges from 1/8 inch (approximately 9.5 mm) to 30 inch (approximately 762 mm) in diameter.
• Wall Thickness: Varies depending on the pipe schedule. Common schedules include:
  • Schedule 40: Provides a good balance between weight and strength. Typical thicknesses range from 2.03 mm (0.08 inch) for a 1/8 inch NPS pipe to 14.97 mm (0.59 inch) for a 30 inch NPS pipe.
  • Schedule 80: Offers increased pressure handling capabilities with thicker walls. Typical thicknesses range from 2.87 mm (0.113 inch) for a 1/8 inch NPS pipe to 18.92 mm (0.745 inch) for a 30 inch NPS pipe.
  • Schedule 160: Designed for high-pressure applications with the thickest walls. Typical thicknesses range from 4.00 mm (0.157 inch) for a 1/8 inch NPS pipe to 25.40 mm (1.00 inch) for a 30 inch NPS pipe.

It is important to consult a pipe schedule chart for specific thickness details based on the desired NPS and schedule.
