What is Stainless Steel Pipe?
Stainless steel is an alloy that contains a high percentage of nickel, chromium, and iron including 10.5% chromium and 1.2% carbon by weight. This stainless steel alloy is well recognized for it's resistance to corrosion, which greatly increases as the chromium content increases. Resistance to reducing acids and solutions including chloride is improved with the addition of molybdenum. The different grades of stainless steel with varying amounts of molybdenum and chromium will be sufficient for a range of environmental conditions. When it becomes contaminated, due to its resistance to staining and corrosion stainless steel products like pipe are in higher demand.

Our Stainless Steel Pipes Product Range Includes
Stainless Steel Seamless Pipes
Stainless Steel Seamless pipes are made from solid billets without welds, which creates a more preferable product for high-pressure and high-temperature installations. Stainless Steel pipe is strong, corrosion-resistant, and uniform.
We manufacture seamless pipes made from stainless steel in sizes from 6NB up to 1200NB, and from 1/8" NPS up to 12" NPS for outer diameter and wall thicknesses from 0.6 mm to 12.7 mm. Our pipes are made for applications that require critical piping and high-performance alloys.
If you are sourcing large diameter stainless steel seamless pipes for a high-pressure pipeline, our experienced technical team can support you in selecting the correct grade, wall thickness and pressure class for your application.
Stainless Steel Welded Pipes
Stainless Steel Welded Pipes are made by welding stainless steel strips together longitudinally with the use of electric resistance. Stainless steel welded pipe is lower in cost and has a consistent wall thickness meaning the installed piping will be suitable for a range of low to medium-pressure applications.
The Stainless Steel ERW Pipe is electric resistance welded but there are electric fusion welded and cold drawn welded pipes as well. There are several standards in this category such as the ASME B36.19 - Stainless Steel Pipe.
Shapes and Dimension of Stainless Steel Pipes
We manufacture and export stainless steel pipe of various shapes and dimensions that includes:-
- Round
- Square
- Rectangular

SS Seamless Pipe Pressure Ratings & Weight
The pipe pressure capacity is directly related to the schedule and wall thickness. For example:
1" SCH40 (WT 0.133”) at 100°F = 2205 PSI
10" SCH40 (WT 0.365”) at 100°F = 699 PSI
Seamless pipes can handle 20% more pressure than welded pipes.

Common FAQs about Stainless Steel Pipes
Stainless steel pipe is used primarily in piping systems for the transport of fluids or gas, often in industries such as oil and gas, chemical processing, water treatment, and food and beverage, due to its corrosion resistance and longevity.
A stainless steel pipe is composed of alloy steel and various elements such as chromium, molybdenum, nickel, etc. Stainless steel has excellent fabrication, corrosion resistance, and strength.
It varies! It depends on the type of stainless steel, the pipe's size (diameter and wall thickness), and the temperature. Stronger materials and thicker walls handle higher pressure. For example, a ¾ inch Schedule 40 steel pipe might handle around 1080 PSI, but this changes with size and material. Always check the manufacturer's specs for the exact safe pressure for your specific pipe.
The longevity of stainless steel piping is impressive. Many installations last over 50 years with proper maintenance.
Stainless steel is excellent for pipes due to its durability, low maintenance, and corrosion-resistant properties. These qualities make it a reliable material that can last for decades without needing frequent replacements.
The best stainless steel pipe depends on the application, but 304 stainless steel is widely considered the most versatile and cost-effective choice. It offers good corrosion resistance and is commonly used in various industries. Solitaire Overseas is a leading manufacturer of stainless steel pipes in India, known for quality products.
Seamless pipes are produced without a weld in a high-pressure process; Welded pipes are generally less expensive, but mainly used in low-pressure systems.
SS Welded pipe can crack under high pressure in comparison to seamless pipe that can withstand extremely high pressure without cracking. Thus, a seamless pipe can carry 20% more pressure than a welded pipe.
When it comes to high-quality steel pipes in India, Solitaire Overseas stands out as a leading manufacturer, supplier, and exporter. With a strong commitment to excellence, we offer a comprehensive range of stainless steel and other alloy pipes designed to meet diverse industrial needs. Our pipes are known for their durability, corrosion resistance, and adherence to stringent quality standards.
