IS 1239 is the standard for black and galvanized steel pipes used in various industrial applications. These pipes can be used for water, gas, steam, air, and other liquids and gases. ERW (Electric Resistance Welded) pipes are a subtype of black steel pipes manufactured using high-quality, low carbon steel. These pipes are preferred due to their durability, strength, and ease of installation. This guide will look closely at ERW pipes, including their different types, sizes, and applications.
What is IS 1239 ERW Pipes?
IS 1239 ERW Pipes are electric resistance welded pipes commonly used for liquid transportation and distribution. These pipes are made from low-carbon steel and are available in nominal bore sizes up to 762mm in various standard lengths, including 4m, 6m & 12m. The ends of these pipes can be supplied plain, beveled or threaded as per the requirement. IS 1239 ERW Pipes have a higher strength than other types of pipe material due to improved welding technologies & manufacturing techniques.
Different Types of IS 1239 ERW Pipes
These pipes come in various grades, sizes, thicknesses, and lengths. The standard specifies four grades of ERW pipes: A, B, C, and D. A grade pipes have a minimum tensile strength of 195 MPa, while grade D pipes have a minimum tensile strength of 320 MPa. The thickness of the pipes also varies from 2 to 12 mm. Depending on the application, the pipes are available in plain and threaded ends.
Sizes of IS 1239 ERW Pipes
These ERW pipes are available in sizes ranging from 15 mm to 150 mm in diameter. Larger diameter pipes are also available but are made to order. The size of the pipes depends on the application, and the standard specifies the minimum and maximum wall thickness for each nominal size of the pipe. For example, the minimum wall thickness for a 15 mm nominal size pipe is 1.8 mm, while the maximum is 3.2 mm.
Applications of IS 1239 ERW Pipes
These ERW pipes find various applications in industries such as oil and gas, water treatment, chemical processing, power generation, and construction. The pipes can convey fluids and gases in pipelines, scaffolding, fencing, and casing. Additionally, ERW pipes are used for fabrication purposes, such as making furniture, handrails, and lighting fixtures.
Advantages of IS 1239 ERW Pipes
ERW pipes have several advantages over other types of pipes. Firstly, they are easy to manufacture and can be produced in large quantities quickly. Secondly, ERW pipes are durable and have a high strength-to-weight ratio. Thirdly, they are more affordable than other types of pipes, making them an ideal choice for mass applications. Finally, ERW pipes have a smooth interior surface allowing easy fluid and gas flow.
Conclusion
IS 1239 ERW pipes are popular in various industries due to their ease of installation, durability, affordability, and strength. These pipes come in various grades, sizes, thicknesses, and lengths and can be used for applications such as pipelines, scaffolding, fencing, and fabrication. With the information provided in this guide, you can now decide whether IS 1239 ERW pipes are ideal for your next project.
