What are the sizes of stainless pipe?

Stainless steel pipes come in a variety of sizes and dimensions to accommodate different applications and industry requirements. The sizes of stainless steel pipes are typically specified by their nominal pipe size (NPS) and schedule. The NPS is a standardized numerical designation that refers to the approximate inside diameter of the pipe, while the schedule indicates the wall thickness of the pipe.

Here are some common sizes and dimensions for stainless steel pipes:

1. Nominal Pipe Sizes (NPS): Common NPS sizes for stainless steel pipes include 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1.5", 2", 2.5", 3", 4", 6", 8", 10", 12", and larger.

2. Schedules: Stainless steel pipes are available in various schedules, which determine the wall thickness of the pipe. Common schedules include SCH 5, SCH 10, SCH 40, SCH 80, and SCH 160, among others. The higher the schedule number, the thicker the wall.

3. Lengths: Stainless steel pipes are typically manufactured in standard lengths, such as 20 feet (6.1 meters) or 24 feet (7.32 meters). Custom lengths can also be obtained.

4. Types: Stainless steel pipes can be classified into different types based on their manufacturing process, such as seamless or welded pipes. Seamless pipes do not have a welded seam and are often considered stronger, while welded pipes are made by welding rolled steel plates together.

It's important to note that the actual dimensions and availability of stainless steel pipes can vary based on the specific grade of stainless steel, manufacturing standards (ASTM, ASME, DIN, etc.), and the supplier or manufacturer. When selecting stainless steel pipes for your project, it's advisable to refer to industry standards, consult with experts, and work with reputable suppliers who can provide accurate information and guidance on sizing and specifications.
