What is Stainless steel pipe 316?

Stainless pipe 316, often referred to simply as “316 stainless pipe,” is a type of stainless steel pipe made from the stainless steel alloy known as 316 or 316L. Here’s what you need to know about it:

Composition: Stainless steel 316 is an austenitic stainless steel alloy containing chromium, nickel, and molybdenum. Its chemical composition typically includes:

– Chromium (Cr): 16-18%
– Nickel (Ni): 10-14%
– Molybdenum (Mo): 2-3%
– Iron (Fe): Balance

The weight of a stainless steel 316 pipe depends on several factors, including its dimensions (outer diameter, wall thickness, and length). Here is a simplified weight chart for stainless steel 316 pipes in some common sizes and schedules. Please note that these values are approximate and can vary based on specific manufacturing tolerances and standards. The weights are given in pounds per foot (lb/ft) and kilograms per meter (kg/m):

NPS (Nominal Pipe Size) – This is a North American standard designation used to describe the size of pipes.

Schedule – The schedule indicates the thickness of the pipe’s wall. Common schedules include Sch 10, Sch 40, and Sch 80.
