What Is The Difference Between Stainless Steel Pipe And Tube
Stainless steel belongs to a ferrous grade that is designed in the form of pipes and tubes. A SS Pipe and tube can be used interchangeably in the system, but these versatile grades can be distinguished on key features.

  • An SS Tube is classified based on its outer diameter and wall thickness. They can also be ordered based on their inside diameter. Black Stainless Steel Pipe is classified on its nominal pipe size and schedule number.
  • Hollow Stainless Steel tubes can also be shaped in the form of square or rectangular cross-sections. Similarly, pipes can be shaped in round configurations, or in special shapes like that of an SS Oval Pipe.
  • SS Oval Pipe is rigid and can only be shaped making use of specialized material to precisely shape it. The grade of the SS Square Tube can be bent or coiled without much distortion or wrinkling of the material.
  • An SS Rectangular Tube is employed in applications where there is a requirement of shape to be stable like in the medical industry. A Stainless Gas Pipe is primarily used in transporting gases and liquids.
  • Electropolished Stainless Steel Tubing can be processed in standard hot and cold rolling procedures followed by galvanization. Stainless Steel Steam Pipe can only be hot rolled and can be galvanized later.
  • A brushed Stainless Steel Pipe is a device that is employed to accommodate larger modules and pipe fittings. The versatile Stainless Threaded Tube is preferred in applications where smaller diameters are required.
  • Seamless SS Tubing is used to perform in applications requiring higher strength and durability. They possess more strength than an Sch 40 SS Pipe.

Both pipes and tubes of stainless steel can be used in specific applications that suit their requirement. The SS Reducer grade in these components allows them to connect to piping components of different shapes and sizes.

What is stainless steel pipe used for?
Stainless steel pipes are generally used in transporting fluids or gases in the systems. They are widely seen in oil and gas systems, chemical processing, nuclear power plants, natural gas, mining, desalination, and so on.

The process of manufacturing Stainless Steel Seamless & Welded Pipe
A stainless steel seamless pipe is manufactured through an extrusion process where the tube is drawn as a steel billet is passed through to form a hollow shape. Here the billets are first heated and then formed into circular molds that are designed in a hollow shape by shaping it in a piercing mill. The hot molds are drawn through a mandrel and later elongated. This process ensures the mold length is increased 20 times to get it shaped in a seamless pipe. The pipe can be later shaped precisely through pilgering and cold rolling or drawing process.

A stainless steel welded pipe is manufactured by roll forming of strips or sheets into a pipe. After this, the components are seam welded longitudinally either by hot or cold forming processes. Cold forming pipes possess superior finish having tighter tolerances; however, hot formed bars are also stable and durable. Similar to seamless pipes a welded pipe can be drawn with finer seam welds having tight tolerances.

Is Seamless Pipe Stronger Than Welded
Seamless pipes are stronger than welded pipe grades. A seamless pipe doesn’t possess any welds and is produced by passing hot steel billets. This allows the pipes in this grade to have 20% higher strength and load-bearing capacity in the system. A stainless steel seamless pipe showcases superior chemical composition, allowing them to be used across harsh environmental conditions.

SS Erw Pipe Vs ASTM A312 Pipes

  • ASTM A312 pipe covers standard specifications for seamless and straight seam welded grades. The austenitic cold worked welded grades are intended for use in high temperatures and general corrosive systems.
  • ERW pipe is produced by cold forming flat strips into a longitudinal seam. The pipes are preferred in low-pressure setups.

ASME Sa 312 Stainless Steel Tube Vs Polished Stainless Steel Tubing

  • ASME Sa 312 stainless steel tube covers seamless and straight welded grades. These components may showcase a rough and uneven surface finish.
  • Polished stainless steel tubing is a grade that is polished till the grade showcases no ridges. These tubes have a shiny, smooth surface having an aesthetical outlook.

Difference Between Seamless And Welded Stainless Steel Pipe
Pipes and tubes in the stainless steel grade are produced in seamless and welded configurations. Both these types can be differentiated on certain key features.

  • A Seamless Stainless Steel Tube is designed without any seams or welds. On the contrary, a versatile grade of the Stainless Steel Welded Tube is produced by a seam welding process. Here the tubes show the presence of seams or welds.
  • A Steel Seamless Tube exhibits 20% higher load-bearing capacity and strength as compared to a welded tube grade.
  • Stainless Steel Welded Pipe is cheaper to process and produce compared to a standard seamless pipe.
  • Stainless Seamless Pipe can be produced in sizes of 24 inches or less. A welded pipe can be produced in different sizes and dimensions.
  • The Ss Seamless Tube has thicker and stronger walls. A welded tube has thinner walls that are lighter in weight.
  • Cold Drawn Seamless Stainless Steel Tube showcases an excellent surface finish with an aesthetically appealing outlook. Welded pipes have somewhat distorted finish due to the presence of welds on their surface.
  • The welds or seams on welded tubes are prone to rusting after exposure to different environmental conditions. Seamless Round Tube showcases excellent corrosion resistance properties.
