Overview
Selection and Usage Guidelines
When purchasing and using, it is recommended to focus on the following points:
Verify Standards: Confirm that the product complies with key standards such as ASTM A403 WP316L-S and ASME B16.9.
Match Parameters: The pipe cap must be ordered according to the pipeline system’s nominal size (DN/NPS) and wall thickness schedule (e.g., SCH 40S).
Choose Suppliers: Prioritize qualified suppliers who can provide a Material Test Certificate (MTC/EN 10204 3.1) to ensure material traceability.
Welding and Post-Treatment: After welding, locally passivate the weld and heat-affected zone if necessary to restore optimal corrosion resistance.
