Answer:
ASTM A106 Grade B pipes are used in high-temperature and high-pressure environments, especially in refineries, boilers, power plants, and oil & gas transmission systems.
Why:
Because of their superior thermal resistance and strength, these pipes perform reliably in steam, gas, and liquid transport under extreme conditions.
Answer:
ASTM A106 pipes are typically seamless.
Why:
Seamless construction eliminates the risk of weak points at weld joints, which is essential for high-pressure and high-temperature applications.
Answer:
A106 is for high-temperature service; A53 is for general mechanical and pressure applications.
Why:
A106 has stricter chemical and mechanical property requirements, making it more suitable for heat-intensive operations.
Answer:
Tensile strength ≥ 415 MPa, yield strength ≥ 240 MPa, elongation ≥ 20%.
Why:
These values ensure the pipe can withstand internal pressure and stress without deforming or failing.
Answer:
The minimum yield strength is 240 MPa (35,000 psi).
Why:
It indicates the pipe's resistance to permanent deformation under load — critical in pressure-based systems.
Answer:
Yes, it's widely used in boiler tubes, heat exchangers, and refinery piping.
Why:
It tolerates high temperatures and thermal cycling — essential in steam-based applications.
Answer:
Equivalent: IS 3589 / IS 1239 (Part 2) for carbon steel pipes.
Why:
Indian projects often follow IS standards, and this helps buyers match equivalent specs for local approvals.
Answer:
Yes, if used in boiler systems, IBR approval is mandatory in India.
Why:
Indian Boiler Regulation (IBR) mandates certified material for pressure parts to ensure safety.
Answer:
Schedules include SCH 20, 40, 80, 160, and XXS.
Why:
Different wall thicknesses are selected based on fluid pressure and flow rate needs in each project.
Answer:
Absolutely. It’s specifically designed for continuous service up to 750°F (400°C).
Why:
High-temp resistance is built into the material’s chemical composition.
Answer:
Not exactly. A106 is for high-temp pressure systems; API 5L is for line pipe transmission.
Why:
Each has different test requirements, chemistry, and temperature ratings.

Why:
Engineers often need this data for design, procurement, or technical submittals.
Answer:
C ≤ 0.30%, Mn 0.29–1.06%, P ≤ 0.035%, S ≤ 0.035%, Si ≥ 0.10%.
Why:
This low alloy blend offers corrosion resistance and high tensile strength under stress.
Answer:
Yes. Pipes can be ordered with PED (EU Pressure Directive) and NACE MR0175 (sour service) compliance.
Why:
Many international EPCs and offshore contractors require certified grades for specific corrosion and pressure specs.
Answer:
Prices vary by size, schedule, quantity, and testing requirements.
