# Junda Pipe Product Evidence Index

> Reviewed 26 October 2026. This index maps all 43 catalogue image entries to the Chinese product page used for the catalogue review. It records what is known for enquiry preparation; it is not a product datasheet, material certificate, approved size list or suitability statement.

## How to use this index

- **Source product page** is the original public product entry associated with the catalogue image. Its label is preserved in Chinese so the mapping can be checked against the source.
- **Geometry and enquiry inputs** describe the dimensions that the drawing or enquiry should define: round tube, profile tube or U-bend. They do not state a manufacturing limit.
- **Material reference** is only shown when the reviewed Chinese alloy archive has a matching entry. “Exact designation requires confirmation” preserves an unresolved source identity; “No matched alloy reference” means this reviewed subset did not supply a matching alloy table.
- **Detail page** links to one of the 23 dedicated product routes where available. Other entries remain in their category gallery and retain their original enquiry path.

Dimensions, tolerances, product standard, supply condition, surface, inspection documents, minimum order quantity and lead time remain project requirements. Submit them through the [technical enquiry](https://jundapipe.com/contact) for confirmation in a quotation. The [Chinese alloy reference archive](https://jundapipe.com/alloy-reference-zh.md) preserves the 50 source pages and their tables; it retains source inconsistencies and is not an order acceptance specification.
