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.

 

This standard is widely used in construction, oil & gas, and low-pressure systems. For critical applications, stricter standards (e.g., ASTM A106 for high-temperature service) may be preferred.

Inspection and Testing

- Hydrostatic testing: Minimum test pressure = 2.4 MPa (350 psi) for ≤ NPS 3 or higher as specified.  

- Nondestructive testing (NDT): Permitted as an alternative to hydrostatic testing for Types E and S.  

- Visual inspection: No defects affecting performance.  

- Certification: Mill test reports (MTRs) must be provided upon request.
