Various material used in pressure vessels for EPC (Engineering, Procurement, and Construction) oil and gas projects.

 The relevant indicator and selection should be analyzed to ensure the design requirement of the project technically accurate.

Key Points:

1. Material Types : The table lists common pressure vessel materials like Carbon Steel, Low Alloy Steel, Stainless Steel, Duplex Stainless Steel, Nickel Alloys, Aluminum, FRP (Fibrous Reinforced Plastics), and Titanium. 

 

2. Properties & Applications: Each material is described with its ASME standard reference, grades, key properties (e.g., corrosion resistance, strength), and typical applications (e.g., storage tanks, separators, LNG units). 

3. Important Codes: Standards like ASME Section II (materials), NACE MR0175 (sour service), API 650/620 (tanks), and ISO 14692 (FRP) are highlighted for compliance checks.  

#Why Is It Matters: 

This table helps engineers select the right material based on project requirements (e.g., cost, temperature, corrosion resistance) while ensuring adherence to industry standards for safety and performance.  

For example:  

- Carbon Steel (SA 516): Affordable but needs corrosion monitoring; used in water storage tanks.  

- Duplex Stainless Steel (2205): Ideal for harsh offshore environments with H₂S and chlorides.  

- Nickel Alloys (625): Used in cryogenic or highly corrosive services like amine units.  

This summary ensures efficient material selection for durability, safety, and cost-effectiveness in oil & gas projects.
