stainless steel pipe schedule chart metric

Charting the thickness of stainless steel pipes offers a helpful metric guide. The outer diameter (OD) and wall thickness are utilized to determine the precise size. The Schedule number is what separates OD from nominal pipe size. For example, a 6-inch Schedule 40 pipe features a 6.625-inch outer diameter and 0.280-inch wall thickness. Metric calculation provides that this is equivalent to 150 mm Schedule 10 tubes.

The Schedule number of a pipe dictates its wall thickness. The computation is rather straightforward – take the Outside Diameter (OD), and subtract it from the Nominal Pipe Size. For instance, a 6-inch Schedule 40 pipe has an OD of 6.625 inches, while its wall thickness is 0.280 inches. Metric counterparts to the 6-inch Schedule 40 pipe are 150 mm Schedule 10 pipes.

The numerical difference between a pipe’s ID and the advertised size is called the Schedule. So, assuming we have a 6-inch package that is labeled as Schedule 40, the outside diameter (OD) would be 6.625 inches and the thickness of the wall would be 0.280 inches. Translating this into metric terms, this would be equivalent to 150 mm Schedule 10 pipe.

Pipes that feature a Schedule number of 40 or greater are considered thick-walled, while those with a Schedule number of 80 or more are extra-thick. However, the Schedule number is not indicative of the actual wall thickness; that is determined by the NPS, or nominal pipe size. As an illustration, a 6-inch Schedule 40 pipe has an outer diameter of 6.625 inches and a wall thickness of 0.280 inches. On the metric scale, this equates to 150 mm Schedule 10 pipe.

Having a schedule number of 40 or higher identifies piping as thick-walled, and those with 80 or greater are determined as extra-thick walled. However, the schedule number does not provide the true wall thickness of the pipe. The proper representation of the thickness lies within the dimensions of the nominal pipe size (NPS). For instance, a 6-inch Schedule 40 pipe has an outside diameter (OD) of 6.625 inches and a wall width of 0.280 inches. In terms of metrics, this is equivalent to 150 mm Schedule 10 pipe.

Pipes with a higher schedule number boast thicker walls; even thicker still are those with a rating of 80 or up. This number, however, should not be confused with the actual wall thickness. This can be gauged by measuring the Outer Diameter (OD) and the nominal pipe size (NPS). To illustrate, a 6-inch Schedule 40 pipe has an OD of 6.625 inches and a wall thickness of 0.280 inches. This equates to 150mm Schedule 10 pipe when translated to the metric system.

The Schedule number of a pipe is used to determine its wall thickness. For instance, 6-inch Schedule 40 pipe has an outside diameter of 6.625 inches, with a wall width of 0.280 inches. Metrically, this is equivalent to 150 mm Schedule 10 pipe.

Pipes with a Schedule number of 40 or greater are thick in comparison to other pipes, while those with an 80 or higher designate exceptional thickness. The measurement given to indicate the wall thickness of a pipe referred to as its Nominal Pipe Size (NPS). For example, a 6-inch Schedule 40 pipe has an outside diameter of 6.625 inches and a wall thicknes of 0.280 inches. To put into metric terms, this would be equal to 150mm Schedule 10 pipe.

Pipes are characterized by varying thicknesses, indicated by their schedule number. Those with a number greater than 40 are considered thick-walled, while those with a number of 80 or more are extra thick. The schedule itself does not dictate the actual wall thickness of a pipe – that is determined by its nominal pipe size (NPS). For example, a 6-inch Schedule 40 tube has an outer diameter of 6.625 inches and a wall width of 0.280 inches; the metric equivalent is 150 mm Schedule 10 pipe.

Pipes that are thick-walled and extra-thick-walled are classified according to the schedule number provided with them. Although this designation does not reflect the actual wall thickness of the pipes, the nominal pipe size (NPS) does. To give an example, a 6-inch Schedule 40 pipe has an outer diameter of 6.625 inches and a wall thickness of 0.280 inches, as measured using the metric system.
