FAQs about API 5L X42 / X52 Pipeline Plates

1. What’s the difference between API 5L X42 and API 5L X52?

The main difference lies in the mechanical strength. API 5L X52 has higher yield and tensile strength than X42, making it more suitable for higher-pressure pipelines.

2. What is the API 5L X52 specification?

The API 5L X52 specification defines chemical composition, mechanical properties, impact testing, and manufacturing methods for PSL1 and PSL2 levels. It is commonly used in high-performance pipeline systems.

3. Can API 5L X52 be used for sour service?

Yes, but only when supplied under PSL2 specification and with additional testing to ensure compliance with NACE MR0175/ISO 15156 standards (typically requiring stricter control of hardness and chemical composition). PSL1 material is not suitable for sour service. Always confirm the specific requirements for your application.
