Product Description

Product Description

Scope  
ASTM A53/A53M specifies requirements for welded and seamless steel pipe in three types:  
- Type F (Furnace-welded, continuous weld)  
- Type E (Electric-resistance welded, ERW)  
- Type S (Seamless)  

Pipes are used for mechanical and pressure applications (e.g., plumbing, steam, air, gas) and are suitable for welding.
