stainless steel pipe thickness schedule

Those in the market for a pipe material that’s sure to provide long-term use and durability, often find themselves leaning towards stainless steel. Available in a variety of sizes and thicknesses, stainless steel is a go-to option for many uses, most typically with Schedule 5, 10 or 40.

Comparatively speaking, Schedule 5 is the thinnest of the three pipe sizes, with a wall thickness of 0.065 inches. This smaller size usually finds a home in low-pressure systems, such as domestic water lines. Moving up to Schedule 10, the wall thickens slightly to 0.088 inches and this pipe is often employed for the purpose of medium-pressure applications, like process piping. Lastly, luxurious Schedule 40 is robust and hefty in size with a wall thickness of 0.109 inches; this pipe delivers when tasked with heavy-duty jobs requiring robust and high-pressure conditions, such as hydraulic lines.

The thickness of a pipe has an inverse relationship to its Schedule number – the higher the number, the less thick the pipe is. As an example, a Schedule 40 one is considerably thicker than a Schedule 5 one. These measurements are expressed in traditional inches.

Selecting the correct stainless steel pipe for the job is critical. Depending on the end purpose, it is important to consider the type of liquid or gas involved, how it will operate at what temperature, how much pressure it will be dealing with, and most importantly the corrosiveness of the contents. From there, you can adjust the wall thickness and ensure your choice is fit for use.

The wall thickness of a pipe is a crucial factor that must be carefully selected, as it should both support the pressure and fluid being transported, while also fitting within an attainable price range. Too thin a pipe will struggle with the demands placed on it and risk failing, while too thick of a pipe will become overly expensive and potentially complicated to install.

Austenitic stainless steel pipes are the go-to option for most piping tasks, with their non-magnetic nature and impressive corrosion-resistance. Manufacturers have made these pipes available in a vast selection of thicknesses and dimensions, giving you more choice than ever.

The magnetic composition of Martensitic stainless steel pipes offers a unique advantage compared to austenitic stainless steel pipes, as it comes with a lower resistance to corrosion. However, these types of pipes are not as readily available in the market.

While not as prolific as austenitic stainless steel pipes, ferritic stainless steel pipes are available. This form of steel has the benefit of being magnetic and having relatively lower vulnerability to corrosion compared to the latter.

With varying characteristics, the appropriate stainless steel pipe for the job is dependent on both the conditions it will be exposed to and the nature of the material being transmitted. It is thus critical to pinpoint the advantages and pitfalls each kind offers in order to ensure optimal functionality.
