Aunov Tech supplies the Stainless Steel Lined Capillary Support Tube 304 SS Chromatography as a stainless steel component manufactured entirely in house. On the product, the deep drawn tube guides or contains the mating part along its bore. Forming, machining and inspection share one floor, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
The specification of this stainless steel tube turns on, the draw ratio, corner radii and the faces that must stay flat, all held to the drawing and verified at first article.
Forming, machining and finishing for this stainless steel tube happen on one site, so revisions do not wait on outside suppliers, and nothing about the route depends on a third party.
How it is manufactured
Manufacturing runs on a controlled process path: Drawing runs from flat blank to finished envelope in one controlled sequence; flanges and rims are formed in the same line, then trimmed to length.
Route cards follow each tall thin-wall cylinder batch through the shop, so the next run starts from the data that already worked. The approved tall thin-wall cylinder sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Materials kept on the floor cover SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel tube is costed in 304 / 316 stainless steel.
Coating and polishing are matched to the end use: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is written into the drawing for this stainless steel tube, so it cannot drift between batches.
Inspection records and material certs for the tall thin-wall cylinder can be supplied with each shipment.
Quality control
The factory operates with ISO 9001 certification: stock arrivals are checked against mill certificates, first articles are measured on a CMM, and production batches are inspected on a sampling plan. Wall thickness on the tall thin-wall cylinder is checked at first article, not assumed. Functional testing – torque, leak or pressure – can be written into the plan, and the inspection report ships with each batch.
Where the part is used
You will find this stainless steel tube inside industrial equipment and general assembly work for OEM and Tier-1 customers.
Drawings for this stainless steel tube are adapted across programmes, so the specification is set by the toughest of them, and the drawing stays common.
Customization and options
What customers usually vary
Variations that come up most often 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, and whether orders run as prototypes, pilot lots or scheduled batches.
The quote for this stainless steel tube separates tooled options from new work, so there are no surprise tooling charges after approval. A written revision is required before any tall thin-wall cylinder change is actioned.
Specifications
| Item | Stainless Steel Lined Capillary Support Tube 304 SS Chromatography |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – DFM notes are returned before any tooling is cut; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so the die charge appears as its own quotation line, and the charge is refundable against agreed volumes. |
| Samples | Prototype and pre-production samples are provided against the drawing, so the approved first article becomes the gauge reference, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; grade and temper are confirmed in writing before tooling. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | Drawn shell with machined seats and threads where the print calls for them; batch records are filed so a repeat order starts from approved data. |
| Equipment | Hydraulic presses for drawing, with CNC turning for finishing, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm on machined seats, sealing faces flat to drawing; critical dimensions carry CMM data with the shipment. |
| Delivery terms | FOB as standard, with DDP offered for EU and US addresses; T/T or L/C, sea or air freight quoted to your door. |
Packaging and delivery
The packing method protects the surfaces of this stainless steel tube: interleaves, polybags or formed trays are selected according to the coating, in sealed cartons on export pallets, with documents issued to your instructions.
