Pipe
9 videos • 85 views • by The Metal Company Stainless Steel pipe is commonly used to transport fluids and gases. It is produced in different sizes and has many uses such as in wastewater systems, food & beverage facilities, chemical processing, oil and gas processing, and more. Stainless steel pipe is non-hygienic as it is hot rolled, which means it is heated up and then rolled through a mill into shape. This leaves it with a rougher surface, which is often dull and referred to as a mill finish. Unlike tube, pipe is always round. You can tell the difference between pipe and tube due to the wall thickness and surface finish. Pipe is thicker and has a rougher finish than tube. We stock stainless steel pipe in both Schedule 10 and Schedule 40. The schedule determines the wall thickness of the pipe. Schedule 10 has a thinner wall thickness than Schedule 40, and is typically used in low-pressure applications while Schedule 40 is used in high-pressure applications. Pipe is measured by Nominal Bore (NB) and Schedule. The term NB (Nominal Bore) is often used interchangeably with NPS (Nominal Pipe Size). ‘Nominal’ is a non-dimensional number that identifies the internal diameter. The wall thickness of pipe is determined by the schedule.
