The term "40s pipe" typically refers to a Schedule 40 stainless steel pipe. The "40" in Schedule 40 refers to the pipe's wall thickness, and it is a commonly used designation in plumbing, construction, and various industrial applications. Schedule numbers like "40s" provide information about the pipe's pressure rating, thickness, and overall strength.Schedule 40s stainless steel pipes are a versatile and widely-used option for many industrial, commercial, and residential applications. They strike a balance between strength, corrosion resistance, and cost, making them suitable for plumbing, HVAC systems, oil and gas pipelines, and more. With proper maintenance, these pipes provide long-lasting, reliable performance in a variety of environments.

For stainless steel pipes, the actual wall thickness and inner diameter depend on the nominal pipe size (NPS) and the schedule number. Here are some examples of typical dimensions for Schedule 40s pipes:

1/2" NPS: Outer diameter=21.34 mm, Wall thickness=2.77 mm

1" NPS: Outer diameter=33.40 mm, Wall thickness=3.38 mm
