Complete Stainless Steel Pipe Schedule Chart for Industrial & Construction Use

Stainless steel pipes are widely used across industries such as construction, oil & gas, chemical processing, and water systems due to their strength, corrosion resistance, and durability. One of the most important aspects of selecting the right pipe is understanding the SS pipe schedule chart, which defines the wall thickness of pipes for different sizes.

SS Pipe Schedule Chart

At Deal On Steel Industries, we provide a complete range of stainless steel pipes along with detailed technical guidance, including pipe schedules, sizes, and weight charts to help engineers, contractors, and buyers make informed decisions.

This guide explains everything about SS pipe schedule, pipe thickness chart, nominal pipe size (NPS), and stainless steel pipe weight, making it a complete reference for industrial and commercial use.

What is Pipe Schedule in Stainless Steel Pipes?

Pipe schedule refers to the wall thickness of a pipe, which directly affects its strength, pressure handling capacity, and durability. It is denoted by numbers such as SCH 10, SCH 20, SCH 40, SCH 80, SCH 160, etc.

The higher the schedule number, the thicker the pipe wall and the greater its ability to withstand pressure. For example, SCH 80 pipes have thicker walls compared to SCH 40 pipes of the same diameter.

Understanding pipe schedules is essential when selecting pipes for applications involving fluid flow, pressure systems, or structural requirements.

Understanding Nominal Pipe Size (NPS) and DN

Before reading the schedule chart, it is important to understand pipe sizing terminology.

Nominal Pipe Size (NPS) is a standard used to define pipe size in inches. It does not always represent the exact outer diameter but serves as a reference for standardization.

Diameter Nominal (DN) is the metric equivalent of NPS and is commonly used in international standards. It represents the approximate internal diameter of the pipe in millimeters.

Both NPS and DN are used together in pipe charts to ensure clarity in global applications.

SS Pipe Schedule Chart (Thickness in mm)

Below is a detailed stainless steel pipe schedule chart showing thickness for common schedules:

NPS (Inch)	DN (mm)	SCH 10	SCH 20	SCH 40	SCH 80	SCH 160
1/2″	15	2.11	2.41	2.77	3.73	4.78
3/4″	20	2.11	2.41	2.87	3.91	5.56
1″	25	2.77	2.87	3.38	4.55	6.35

SS Pipe Weight Chart (Per Meter)

The weight of stainless steel pipes depends on diameter and thickness. Below is an approximate weight chart:

NPS	SCH 40 Weight (kg/m)	SCH 80 Weight (kg/m)
1″	2.50	3.24
2″	5.44	8.07
3″	10.25	14.98
4″	16.07	22.32
6″	28.26	42.56

Types of Stainless Steel Pipes

Stainless steel pipes are available in different types based on manufacturing methods and applications.

Seamless pipes are manufactured without welding joints, making them stronger and suitable for high-pressure applications such as oil & gas and chemical industries.

Welded pipes are made by rolling and welding steel sheets. They are cost-effective and widely used in construction and general industrial applications.

ERW pipes (Electric Resistance Welded) are commonly used in structural and low-pressure applications due to their affordability and consistent quality.

Applications of SS Pipes

Stainless steel pipes are used across multiple industries due to their corrosion resistance and strength. In construction, they are used for structural frameworks, railings, and plumbing systems.

In the oil and gas industry, SS pipes are essential for transporting fluids under high pressure and temperature conditions. Their resistance to corrosion ensures long-term reliability.

In chemical and pharmaceutical industries, stainless steel pipes are used because they do not react with chemicals and maintain purity standards.

They are also widely used in water supply systems, food processing units, and marine applications.

Advantages of Stainless Steel Pipes

Stainless steel pipes offer several advantages that make them superior to other materials.

They provide excellent corrosion resistance, making them suitable for harsh environments. Their high strength allows them to handle pressure and mechanical stress effectively.

They are durable and require minimal maintenance, reducing long-term costs. Additionally, stainless steel pipes are environmentally friendly and recyclable.

How to Choose the Right Pipe Schedule

Selecting the correct pipe schedule depends on several factors, including pressure requirements, temperature conditions, and application type.

For low-pressure applications such as water flow, SCH 10 or SCH 20 pipes are generally sufficient. For medium-pressure systems, SCH 40 is commonly used.

High-pressure applications, such as industrial pipelines and chemical processing, require thicker pipes like SCH 80 or SCH 160.
