Stainless Steel Pipes in India: Sizes, Grades, and Schedules Available at Altra Enterprise

However, when purchasing stainless steel pipes, their size is one of the most critical considerations.

Stainless steel pipes come in many different sizes, and manufacturers typically measure them by nominal bore (NB). In simple words, the pipe size refers to its inner diameter, and this directly affects how much fluid can flow through the pipe at a given time.

At Altra Enterprise, stainless steel pipes are available in sizes ranging from 1/4 inch NB to 16 inches NB. To make this easier to understand, here is what these size ranges generally mean in practical terms:

Small pipes (1/4” NB to 1” NB) – These pipes are ideal for small-scale businesses, laboratories, and household use.

Medium pipes (1 1/4” NB to 6” NB) –Factories and industrial facilities commonly use these pipes to transport chemicals or water.

Large pipes (8” NB to 16” NB) – These pipes are ideal for large industrial pipelines, power stations, or water treatment plants.

Selecting the right size is critical. If you choose a pipe that is too small, efficiency drops. On the other hand, if you choose a pipe that is too large, costs increase unnecessarily, and handling becomes more difficult.

Understanding Stainless Steel Pipe Grades

Not all stainless steel pipes are created equal. There are different grades of stainless steel pipes, which vary in strength, corrosion resistance, and intended use.

Altra Enterprise supplies a wide range of stainless steel pipes, including:

TP304 and TP304L – To begin with, these stainless steel pipes serve as general-purpose options for many industries. They resist rust effectively and work well for water, chemical, and food service applications. In addition, the “L” in 304L stands for low carbon, and this lower carbon content improves corrosion resistance even further.

TP316L and TP316Ti – These are suitable for more corrosive environments. For instance, chemical processing plants or those near the coast. They are more resistant to chlorides and acidic conditions than 304.

TP309, TP310, TP310S – These pipes are designed for high-temperature services. They are ideal for furnaces, boilers, and heat exchangers.

TP321 – These pipes are used in chemical processing plants and for services involving high stress at high temperatures.

TP202 – These pipes are cost-effective and are suitable for non-critical applications where high corrosion resistance is not necessary.

Each grade has its strengths. Choosing the right grade depends on where and how the pipe will be used. At Altra Enterprise, experts can guide you in selecting the best grade for your project.

What Are Pipe Schedules and Why Do They Matter

You may have noticed markings such as SCH 5, SCH 10, SCH 20, SCH 40, SCH 160, or SCH XXS. These numbers represent the thickness of the pipe wall, which is responsible for the pressure rating of the pipe.

Here is a simple explanation:

Thin-walled pipes (SCH 5, SCH 10) – Low-pressure applications, such as small water or gas lines.

Medium-walled pipes (SCH 20, SCH 40) – Used in standard industrial applications. They are a good mix of strength and economy.

Thick-walled pipes (SCH 160, SCH XXS) – High-pressure or high-temperature applications, such as chemical or power plants.

The thicker the pipe wall, the higher the pressure rating, but also the heavier and more expensive the pipe will be.

Seamless vs Welded Stainless Steel Pipes

There are two kinds of stainless steel pipes, namely seamless and welded.

Seamless pipes: To begin with, these pipes have no welded joints, which makes them especially strong and reliable. As a result, they handle high-pressure applications effectively, providing the durability and consistency that industries need.

Welded pipes: These pipes are made by rolling the metal and welding it along the seam. As a result, they offer a more economical option and work well in low-pressure applications.

At the same time, Altra Enterprise supplies both types of pipes, allowing you to choose the option that best suits your application and budget.

Applications of Stainless Steel Pipes in India

Industries use stainless steel pipes across a variety of sectors. Some common examples include:

Chemical Industry – The pipes transport acids, alkalis, and other corrosive materials safely.

Food and Beverage Industry – The pipes transport water, milk, juices, and other liquids without any contamination.

Pharmaceutical Industry – The stainless steel pipes maintain cleanliness and meet the strictest requirements.

Power Plants –These pipes perform well in boilers and cooling systems because they resist high temperatures.

Construction and Water Supply – Large pipes serve water supply and construction projects. Each sector may require different sizes, grades, and schedules of stainless steel pipes, so it is important to work with a reliable supplier.

Size – The appropriate nominal bore is necessary for proper flow and efficiency.

Grade – Select according to corrosion, temperature, and durability requirements.

Schedule – The wall thickness should be in accordance with the pressure and stress of the system.

Seamless or Welded – Depending on pressure, cost, and application.

Altra Enterprise can assist you in this process.

Maintenance and Longevity

Stainless steel pipes are low-maintenance but still need care:

• Regular Cleaning – Prevents deposits and maintains flow.
