Produced in stainless steel by Aunov Tech, the 304 precision stainless steel capillary variable diameter tube is formed and machined on the same floor. Once installed, the deep drawn tube carries fluid or motion through a closed drawn wall. Drawing, cutting and measurement sit on one floor, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
For this stainless steel tube, the drawing centres on, the forming route, the tolerance band and the sealing faces, checked by CMM at first article and by gauge in production.
Die building, pressing and machining for this stainless steel tube are all in house, so revisions do not wait on outside suppliers, and the die record stays with your part number.
How it is manufactured
This is how the stainless steel tube is built: Coil is blanked and then drawn down in successive stages; flanges and rims are formed in the same line, then trimmed to length.
Every hex-top tube sleeves, order keeps its trace back to the approved first article, and a reorder is a repeat rather than a new start. The approved hex-top tube sleeves, sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel tube runs in 304 / 316 stainless steel.
The surface treatment is picked to match the service conditions: zinc and nickel plating, chrome, anodising, powder coating and passivation. The choice is recorded on the drawing for this stainless steel tube, so the decision never has to be made twice.
Repeat hex-top tube sleeves, orders are measured against the approved sample, so neither material nor finish drifts between lots. Mill certificates are filed per heat, so hex-top tube sleeves, traceability survives a change of material batch.
Quality control
Production runs under an ISO 9001 certified quality system: certificates verify each incoming batch of material, first articles are measured on a CMM, and production batches are inspected on a sampling plan. The hex-top tube sleeves, first article records wall thickness along the length. If the assembly calls for torque, leak or pressure proof, the test is built into the quality plan, and the inspection report ships with each batch.
Applications
Typical installation of the stainless steel tube is in industrial machinery and equipment assemblies under schedules that run for years at a time.
This stainless steel tube is supplied to several positions in the same machine, so a single grade and coating can cover each application, and the drawing stays common.
Customization and options
Where designs usually differ
Typical decisions customers make on this stainless steel tube: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, with orders run as prototypes, pilot lots or scheduled call-offs.
The quote for this stainless steel tube separates tooled options from new work, so new tooling is only quoted where it is genuinely required. Revisions to the hex-top tube sleeves, drawing only take effect once approved.
Specifications
| Item | 304 precision stainless steel capillary variable diameter tube |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – DFM notes are returned before any tooling is cut; the agreed version governs every later batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so the die charge appears as its own quotation line, and ownership is confirmed on the quotation. |
| Samples | Sample parts are measured and reported before submission, so any deviation is corrected at sample stage. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Plating, coating or polishing to suit the drawing; the finish is inspected with the dimensional report on the first article. |
| Processing | Tube drawing, straightening and turning in one flow; every stage is logged against your part number. |
| Equipment | Tube drawing benches with in-line annealing furnaces, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm on turned diameters, wall held to the agreed band; capability is checked on the first article before the run continues. |
| Delivery terms | Standard terms FOB; DDP available for EU and US, with T/T and L/C accepted. |
Packing and shipment
Finish comes first when packing this stainless steel tube: interleaving, individual bags or trays are chosen by finish type, in sealed cartons on export pallets, documented and marked to your instruction.
