Choose a single stainless alloy and construction route for the tubing being ordered.

Alloy and construction

The title names several stainless grades and requests seamless pipe. The description also lists welded routes, so confirm actual construction and material evidence instead of assuming the entire grade list is supplied seamlessly.

OD and wall pairing

The actual thickness option is a 0.4–30 mm range, while the description gives another wall range and broad OD wording. Specify a compatible actual OD and wall; a range label does not establish every tube combination.

• Actual stainless designation
• Seamless or welded route
• Compatible OD and wall
• Surface finish and cut length
• End preparation and inspection

Application requirements

Petroleum, chemical and mechanical uses are mentioned. Agree the applicable standard and service tests for the actual tube; finish names and schedule references do not establish pressure performance, chemical compatibility or automatic schedule compliance.
