The Differences Of A53 Pipe And A106 Pipe
- Jan 17, 2018 -

(1)Scope

ASTM A53 is a kind of Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless.

ASTM A106 is a kind of Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service.

(2)Applied Type

ASTM A53 is for welded or seamless decided by purchasers'requirements,which is a general steel pipe specification and covers galvanized pipe as well as black pipe.

ASTM A106 is similar pipe to ASTM A53 in chemical composition but is intended for high temperature service (up to 750 Degs F),which is a seamless pipe.
At least in the US, there is usually A53 for welded pipe, and ASTM A106 is seamless. If you ask for A53 in the US they will quote A106 as an alternate.

(3)Chemical Composition

For example when we compare between A106-B and A53-B seamless from chemical composition point of view, we find that
1. A106-B contains silicon, min. 0.10% where A53-B has zero%, and silicon is the important element for improving the heat resistance criteria.
2. A106-B contains manganese 0.29-1.06%, where A53-B 1.2%.
3. A106-B contains low sulfur and phosphorus, max. 0.035% where A53-B contains 0.05 and 0.045% respectively.

 (5)Other Differences

Because they have different scope and specify different type of pipe, then the manufacturing process and required quality control test and inspection will be different to each other. Leave a comment if you have specified opinion.
