Agree nominal size and actual dimensions before accepting a pipe schedule for chemical service.

OD and schedule

The title requests 25 and 30 mm with SCH40, while the detailed OD field is 50 without a unit. Confirm actual diameter and nominal pipe size rather than treating these references as a verified schedule combination.

Wall and grade

The actual thickness option is 2.5 mm, with broader wall and diameter descriptions. Select the actual stainless alloy and a compatible wall, and verify schedule requirements for that size.

• Actual stainless designation
• Nominal pipe size and schedule
• Compatible OD and wall
• Selected surface and length
• Chemical service inspection

Service evidence

Seamless round construction and multiple finishes are described. Provide fluid, temperature and pressure requirements; application wording does not establish chemical compatibility, corrosion lifetime, pressure rating or compliance for every listed grade and finish.
