ASTM 201 Stainless Steel Galvanized Tube Pipe 304 304L 316 316ti 310S 309S 2205 Welded
Pipe comes in a very wide range of sizes in which with Power and Process piping, designers utilize standards controlled by organizations such as ASTM and ASME. Unified Alloys readily stocks various alloys and grades in sizes up to 36” Nominal Pipe Size (NPS), which meet these standards.
The most common industry pipe sizes includes ¼” through to 12″ NPS and larger sizes typically increase in 2″ increments thereafter. The Nominal pipe size (NPS) pertains to the pipe size by name only, as the actual outside diameter or O. D. is different for the 12″ and under size range.
In piping dimensions, the inside diameter decreases as the as the wall thickness increases on all Nominal pipe sizes (NPS). The wall thicknesses are specified as ‘schedules’ which are covered within the specifications of ASTM and ASME. Pipe is offered in 20’ lengths, but can be supplied in certain sizes in double random (+/- 40’) to meet certain project needs.
Pipe is manufactured in either welded and or seamless form. Welded pipe is made by taking a flat plate (or skelp) which then is rolled into a tubular shape and further welded to finalize the form. Seamless is taking a solid bar (ingot), piercing a hole through its length and then drawing through dies to form the final size.
