How Thick Is Schedule 40 Pipe Vs 80 Steel Pipe

Table of Contents

How thick is schedule 40 pipe? In the field of pipeline engineering, it is very important to choose the right steel pipe. Among them, Schedule 40 pipe is a common pipe specification. For example, 6 Schedule 40 pipe, 2 schedule 40 pipe, 4 inch schedule 40 pipe.

Schedule 40 vs Schedule 80 steel pipes have different wall thickness and strength characteristics, and they are widely used in various engineering scenarios.

In this paper, the wall thickness and specifications of these two kinds of steel pipes are compared and analyzed in detail, and their considerations in engineering applications are discussed.

How Thick Is Schedule 40 Pipe-ASME B36.10M Thickness&Specification

Schedule 40 Piping specifications are classified and labeled according to American standard ASME B36.10M. How thick is Schedule 40 pipe? Its wall thickness value is not fixed, and is generally calculated according to the outside diameter and nominal pressure (PN) of the pipeline.

For example, a pipe with an outer diameter of 168.3mm has a Schedule 40 wall thickness of 7.11mm. Schedule 40 steel pipe with a 1/2 inch diameter has a minimum wall thickness of approximately 0.133 inches (approximately 3.38mm). On the other hand, the length and material of Schedule 40 pipeline will also have a great impact on wall thickness and mechanical properties.

The performance of Schedule 40 Pipe also varies with the wall thickness.

  • Impact resistance: Under the impact of external force, Schedule 40 Pipe can maintain a sound structure to avoid leakage and rupture and other safety accidents.
  • Lightness: Schedule 40 steel pipe itself is light, which has great advantages in the transportation, installation and maintenance of steel pipe.
  • Corrosion resistance: Schedule 40 carbon steel pipes can have excellent corrosion resistance in harsh environments such as moisture, acid and alkali, improving cost effectiveness.
