Stainless Steel Products offers carbon steel and stainless steel pipes/tubes in welded and seemless configuration. We offer round, square, and rectangular tubes in various thickness and lengths.
Pipes are distinguished from tubes in that Outside diameters of Tubes are the exact sizes requested. A 6" tube has a 6" outside diameter. However, pipe diameters are typically larger than specified. Referencing the chart below, a 6" pipe would have a 6 5/8" outside diameter.
The next consideration when specifying tubes or pipes is the WALL THICKNESS. This will help determine the strength of the pipe as well as the flow rates through the pipe. Flow rates are a function of several factors, most important of which is, the inside diameter of the tube or pipe.
