1. What are IS 1239 pipe grades?

IS 1239 is the Indian Standard for the specifications of hot-finished or cold-finished steel tubes used in water, gas, air, and steam lines. The standard applies to both seamless and welded tubes. It has four parts, each covering a different aspect of tubes and a different level of thickness.

The standard has four parts:

IS 1239 (Part 1):2004: This section is about the Light, Medium, & Heavy series, tubes with wall thicknesses of up to 6mm, 6mm to 50mm, and over 50mm, respectively.

IS 1239 (Part 2):2007: This part talks about the Heavy series tubes, which have more than 50mm thick walls.

IS 1239 (Part 3):1992: This part talks about the Light and Medium series tubes, which have wall thicknesses between 6mm and 50mm.

IS 1239 (Part 4):1990: This part talks about the Medium and Heavy series tubes, which have wall thicknesses between 6mm and 50mm and over 50mm, respectively.

2. What are IS 1239 and IS 3589 Differences?

IS 1239 pipe and IS 3589 pipe are Indian Standards that need to be used for water and sewage. The difference between the two is:

IS 1239: Detailed specifications for pipes with nominal bore sizes between 15 mm and 500 mm, used in medium and heavy-duty applications.

Includes details for both black and galvanized pipes.

The pipes meet the following specifications:

  • There shouldn't be less than 330 N/mm2 of tensile strength.
  • The yield strength should be at least 245 N/mm2.
  • The lengthening should be at least 22%.

IS 3589: This document details the specifications for steel pipes with a nominal diameter size between 40 mm and 400 mm.

It has rules for longitudinal submerged arc welded (LSAW) and spiral submerged arc welded (SSAW) pipes.

The pipes meet the following specifications:

  • There shouldn't be less than 410 N/mm2 of tensile strength.
  • The yield strength should be at least 245 N/mm2.
  • The lengthening should be at least 20%.
  • At 0°C, the impact should have at least 27 J of energy.

3. IS 3589 equivalent to ASTM?

IS 3589 differs from any specific ASTM (American Society for Testing and Materials) standard. But IS 3589's requirements for steel pipes are similar to those of ASTM A53, ASTM A139, and ASTM A252, all standards for water and sewage systems.

It's important to remember that even though IS 3589 and ASTM standards may have some similarities, they are not the same and may have different requirements. When choosing pipes for a project, it's essential to check the standards and codes in the area to ensure you're selecting the right material and following the rules.

4. How much are Saudi Arabia customs duties on IS 1239 pipe?

Imports into Saudi Arabia are subject to customs taxes, which the government collects as taxable income. The Saudi Arabian Customs Authority decides the rate of duty based on the type of goods being brought into the country. Most rates are between 0 and 20%, but some goods may have higher duties.

Other fees and taxes, like the value-added tax (VAT), may also be added to goods brought into the country. Customs laws and regulations can change often, so it's best to check with the Saudi Arabian Customs Authority for the most up-to-date information before bringing goods into the country.

5. Where IS 3589 pipe used?

IS 3589 pipe are usually used in high-pressure pipelines for water supply, irrigation, sewage treatment, and gas and oil transportation. They are also used in other applications that necessitate high strength and durability, like:

  • Large-diameter pipes are used to carry water to cities and industrial plants.
  • Pipelines that use high pressure to transport oil, gas, or other petroleum products.
  • The mining and minerals industry uses pipes to transform slurry and other rough materials.
  • Pipes for sewage treatment and getting rid of wastewater.
  • Pipelines to get drinking water to places that are far away and rural.

IS 3589 is known for being solid and durable, so that it can be used in hard and demanding environments.

IS 3589 is made from high-quality mild steel, which makes them very resistant to wear and corrosion. Modern methods of making pipes, such as electric resistance welding (ERW) or longitudinal submerged arc welding (LSAW), are used to ensure the pipes are of consistent quality and the correct size.

IS 3589 is a flexible and reliable way to build high-pressure pipelines for various uses. Pipeline projects can use them because they are cheap, easy to set up, and environmentally friendly.
