# How to Prepare a Technical Enquiry for Junda Pipe

Canonical: https://jundapipe.com/en-AU/blog/junda-pipe-technical-rfq-checklist

Build a clear Junda Pipe RFQ from product, grade, dimensions, inspection and destination, with an illustrative request and quotation comparison method.

A useful Junda Pipe enquiry identifies the required product, material, dimensions, quantity, inspection and delivery destination. Attach a drawing or specification where it controls acceptance, and ask for deviations to be stated explicitly. This gives both buyer and supplier a common basis for a technical response.

Junda Pipe identifies itself as Zhejiang Junda Steel Pipe Manufacturing Co., Ltd.; its product range is presented under the Jungang brand. [Company source](https://jundapipe.com/about) Use the exact company and product identity when checking an offer, rather than assuming every business with “Junda” in its name is the same entity.

## Which catalogue entry should be selected?

Junda’s [product catalogue](https://jundapipe.com/products) has six groups: high-nickel alloy pipes, super duplex steel pipes, austenitic stainless steel pipes, precision tubing, profile tubing and seamless pipes for military standards. Select the closest relevant entry, then state the actual specification. A category name does not establish a certification or approval for a project.

For names that need clarification, preserve the original wording in the enquiry. The catalogue’s S22053 and Incoloy 800T entries should be confirmed rather than automatically replaced with similar designations. The [800-series guide](https://jundapipe.com/blog/incoloy-800-800h-800ht-designation) explains that issue.

## What should the request contain?

| Field                | Useful content                                                      |
| -------------------- | ------------------------------------------------------------------- |
| Product and material | Exact grade, product form and catalogue reference if relevant       |
| Standard             | Product specification, edition and additional project requirements  |
| Dimensions           | OD and wall or NPS and schedule, wall basis, lengths and tolerances |
| Quantity             | Pieces, total length or mass with a clear conversion basis          |
| Condition            | Required heat treatment, surface and end finish                     |
| Inspection           | Methods, sampling, criteria, witnessing and required documents      |
| Delivery             | Destination, requested date and packing constraints                 |
| Alternatives         | Whether substitutions may be proposed and how they will be approved |

[ASTM A312/A312M-25](https://store.astm.org/a0312_a0312m-25.html) illustrates why grade, manufacturing route and supplementary requirements belong in the product description. For applicable tube standards, [A1016/A1016M-24a](https://store.astm.org/a1016_a1016m-24a.html) explains the relationship between product and more stringent order requirements. Use the full governing documents for the actual purchase.

## What does a clear preliminary request look like?

The following is a fictional enquiry example, not a Junda offer or stock claim:

> Please review a requirement for 100 seamless austenitic stainless tubes, each 6,000 mm long, with 25.0 mm OD and 1.5 mm nominal wall. The project engineer will provide the approved grade, specification edition, tolerances and inspection schedule before order release. Please state feasible supply scope, required clarifications, proposed deviations, documentation and packing. Delivery destination is to be specified in the final RFQ. Do not substitute a grade without written approval.

The example deliberately distinguishes a preliminary enquiry from a purchase-ready order. Before release, replace every unresolved item with the approved requirement. Do not let a supplier’s quotation assumption become an unnoticed change to the design.

## How should the response be compared?

Separate confirmed technical compliance, proposed deviations and commercial terms. Close technical uncertainties before treating prices as comparable. Confirm whether inspection, documents, packing and delivery scope are included.

Use the [Junda contact page](https://jundapipe.com/contact) to submit the completed request. Keep the enquiry reference with the accepted quotation, order revision and eventual material records. A submitted enquiry or a contact-page visit is not evidence of an accepted order, available stock or a confirmed delivery date.
