What is Stainless Steel Pipe?
The construction of a pipe is round, which means the cross-section of the component is round and hollow in the center. These components are used in a piping system to distribute fluids including pellets, dust, gases, and fluids, or even steam. One of the very important distinguishing characteristics of pipes is their size. These dimensions include inside diameter or ID, outside diameter or OD, and wall thickness or WT. The wall thickness is also called the pipe schedule. Dimensions of a pipe help to the liquid capacity of the Stainless Steel Pipes. This can be determined by calculating the outside diameter minus 2 times the WT or the wall thickness (or program).
What is Stainless Steel Tube?
While a tube configuration is always round, the manufacture of tubes is possible in a variety of shapes, including round, rectangular, square, or oval. Similar to tubes, these components have dimensions such as outside diameter and weight, making them easier to order. The hollow section of pipe components is estimated from outside diameter or outside diameter, in combination with wall thickness or WT. The only difference between Stainless Steel Tubes and pipe is that for pipes, these dimensions are in inches or millimeters. The dimensions of the pipe often indicate the precise dimensional value of its hollow section.
Types of Stainless Steel Pipes
- Seamless Stainless Steel Pipes: Seamless stainless steel pipes are made without any welded joints.
- Welded Stainless Steel Pipes: Welded stainless steel pipes are manufactured by rolling stainless steel into a tube shape and welding the edges together.
- Round Stainless Steel Pipes: Round stainless steel pipes are the most commonly used type of pipe due to their versatility.
- Square and Rectangular Stainless Steel Pipes: Square and rectangular stainless steel pipes are used for specific structural and aesthetic applications.
- ERW (Electric Resistance Welded) Pipes: ERW pipes are a type of welded pipe where the edges are fused using electric resistance instead of traditional welding.
Types of Stainless Steel Tubes
- Seamless Stainless Steel Tubes: Seamless stainless steel tubes are made from a solid stainless steel billet that is heated and drawn into a tube without any joints.
- Welded Stainless Steel Tubes: Welded stainless steel tubes are produced by welding together the edges of stainless steel strips.
- Precision Stainless Steel Tubes: Precision stainless steel tubes are manufactured to tight tolerances, ensuring they meet specific size and shape requirements.
- Heat Exchanger Stainless Steel Tubes: Heat exchanger stainless steel tubes are designed to facilitate the transfer of heat between fluids in heat exchangers.
- Capillary Tubes: Capillary tubes are very small-diameter tubes used in delicate applications where precise fluid control is required. They are manufactured with extreme precision and are commonly found in the medical and scientific industries.
Key Differences Between Stainless Steel Pipe and Tube
| Feature | Stainless Steel Pipe | Stainless Steel Tube |
|---|---|---|
| Shape | Mostly round | Can be round, square, or rectangular |
| Measurement | Nominal Pipe Size (NPS) & Schedule | Outer Diameter (OD) & Wall Thickness |
| Applications | Fluid and gas transport | Structural, mechanical, and precision uses |
| Strength | Generally thicker walls for pressure resistance | Higher dimensional accuracy for precision applications |
| Fabrication | Easier to weld and thread | More precise machining required |
| Cost | Often lower per unit length | More expensive due to precision requirements |
| Surface Finish | Rougher surface | Available in polished, seamless finishes |
Difference Between Pipe and Tube Diameter
During placement of the order, it is possible to order, you can order a pipe with dimensions such as outside diameter and wall thickness. In addition, in a few instances, the order can also be positioned with dimensions like OD & ID and Wall Thickness. Generally, the ID or the internal diameter is theoretical, however, the wall thickness of a given tube has been described with the aid of using a gauge quantity. Smaller gauge numbers are related to having large outdoor diameters. On the alternative hand, the tube is ordered with the NPS standard, additionally, this system quantity and the amplifier; nominal diameter or pipe length need to be specified.
Pipe and Tube Production Process
Similar to pipes, tubes may be produced with both seamless or welded construction. In addition, it is very difficult to manufacture a tube because the tolerances of the tubes are tighter. The manufacturer must therefore comply with all of them to meet the tolerances established by the standards or specifications. And because the manufacturing process of tubes entails a finished product, several parameters need to be reviewed, including test procedures, quality controls, and inspections.
Applications of Stainless Steel Pipes and Tubes
Stainless steel pipes and tubes are widely utilized across various industries due to their durability, strength, and corrosion resistance. Their ability to withstand extreme conditions, including high temperatures and pressure, makes them ideal for diverse applications.
