For projects specified in JIS A-size piping, this 316L EP pipe provides a separate dimensional route from fractional ASTM tubing. Review the drawing's outside diameter and 5S or 10S wall before matching an EP surface grade and cleaning requirement.
Technical parameters

Catalog dimensions are selection references. Confirm the exact grade, finish, geometry and inspection documents against the approved order drawing.
Application and selection
This pipe family suits laboratory gas headers and larger clean distribution runs built around JIS components. Keep the A-size designation, actual outside diameter and weld interface together on the purchase specification to avoid an ASTM/JIS mismatch.
What to send for a quotation
Provide the JIS A-size, 5S or 10S wall, required length, gas compatibility requirement, internal finish target and the mating fitting standard. Contact LGF with your requirements.
