Carbon Steel Pipes & Tubes Manufacturer and Supplier in India
Home > Pipes & Tubes > Carbon Steel Pipes & Tubes
Kalpataru Piping is a manufacturer and supplier of carbon steel pipes and tubes, material made from iron-carbon alloys, and is considered a highly valuable material in many of the industries, due to its strength and lower cost compared to alloyed materials. Our ASTM A106 Grade B pipe, ASTM A53 Grade B pipe and API 5L Grade B pipe undergo testing to ensure that the mechanical properties are consistent throughout the pipe’s length and diameter that is ordered. The tensile strength of carbon steel pipes is 400-700MPa, depending on the grade and thickness, and the yield strength is 250-500MPa, and they are widely used in process piping, construction and other general industrial applications where corrosion resistance is not an important requirement. If corrosion resistance is needed, please choose our stainless steel pipes and tubes or alloy steel pipes and tubes for higher temperature applications.

Frequently Asked Questions
What is the difference between carbon steel pipe and steel pipe?
Carbon steel pipes are stronger and more durable than regular steel pipes due to their higher carbon content. This gives them greater tensile strength, allowing them to handle more pressure without becoming brittle.
What is the standard for carbon steel pipe?
Carbon steel pipes are manufactured to several standards, including ASTM/ASME SA106 (Grades A, B, C), ASTM/ASME SA53 (Grades A, B), API 5L (PSL 1 Grades A, B, X42, X46, X52, X56, X60, X65, X70), and ASTM/ASME SA333 (Grades 1, 6).
What is the minimum thickness of carbon steel?
Carbon steel plates typically range from 0.4 mm to 80 mm in thickness, up to 18 metres long, with customizable lengths for various applications.
How do I choose between A106 Gr B and A53 Gr B?
A106 Gr B suits higher-temperature/process piping; A53 Gr B fits general/structural use and is often cheaper. Choose A106 Gr B for elevated temperature or pressure service.
What affects price and lead time?
Grade, thickness, size, and manufacturing type (seamless costs more) drive price. Stock vs. custom sizes/testing affect lead time. Share specs for accurate quote.
