Aunov Tech builds this One End Closed 304 Fitting Stainless Steel Pipe Tube for Thermocouple in brass or stainless steel, from coil or bar through to the finished surfaces. On the product, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. One production floor covers forming, finishing and inspection, so the approved sample defines every later batch without re-quoting the job elsewhere.
Product overview
For this stainless steel fitting, the drawing centres on, material grade, wall uniformity and thread position, re-checked whenever the drawing is revised.
Die building, pressing and machining for this stainless steel fitting are all in house, so revisions do not wait on outside suppliers, and the approved sample is kept as the master.
How it is manufactured
Production follows a defined route: Blanks are drawn in stages, with interstage annealing where the wall thins; threads are single-pointed or rolled and seats bored in one setup where possible.
Production batches of the open-top cylinder are gauged back to the signed first article, not to a memory of it. Any change to the open-top cylinder drawing is re-approved and re-verified before production continues.
Materials and surface finish
Working stock covers carbon steel SPCC / DC01, 304 and 316 stainless, aluminium, brass and copper with this stainless steel fitting costed in 304 / 316 stainless steel.
Finish selection follows the working environment: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is fixed on the drawing for this stainless steel fitting, so repeat orders never reopen the question.
The open-top cylinder manufacturing record is archived together with the drawing revision that produced it. Deviations on the open-top cylinder are reported before shipment rather than found on your assembly line.
Quality control
The plant is ISO 9001 certified: mill certificates cover every delivery of stock, first articles are measured on a CMM, and every production run is inspected against the first-article report. First articles of the open-top cylinder are CMM measured, with threads gauged to class and diameters recorded. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the report is packed with the shipment.
Typical applications
This stainless steel fitting normally works inside industrial machinery and equipment assemblies for customers who buy to drawing.
The same stainless steel fitting is used across several platforms, so one approved version covers the whole range, and the drawing stays common.
Customization and options
Where designs usually differ
The options most often changed on this stainless steel fitting: material grade, wall band, flange shape, thread size and finish for the working environment, with orders run as prototypes, pilot lots or scheduled call-offs.
Quotes for this stainless steel fitting show which options the current die already supports, so you are not charged twice for a feature the die already makes. The open-top cylinder reorder shows the same split as the original quotation.
Specifications
| Item | One End Closed 304 Fitting Stainless Steel Pipe Tube for Thermocouple |
|---|---|
| Brand | AUNOV |
| Designing | Driven by your drawing or a physical sample – unusual walls, threads or tolerances are feasibility-checked first; the same drawing is used for every repeat order. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and maintenance is tracked against the part number. |
| Samples | Sample parts are measured and reported before submission, so the part is proven before it is made in volume, and mass production is gated on that approval. |
| Materials | Carbon steel, 304 / 316 stainless, aluminium and brass are all held in stock; material substitutes are proposed only with your written approval. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; masking and laser marking available where needed. |
| Processing | Deep drawing on hydraulic presses, CNC-finished where tolerances tighten; in-process checks sit between stages, not only at the end. |
| Equipment | Deep drawing presses plus CNC turning centres for machined faces, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on sealing faces, +/-0.05 mm on drawn profiles; finer bands confirmed from capability data before quoting. |
| Delivery terms | Terms are FOB by default, with CIF and DDP quoted on request and freight priced to your door. |
Packaging and delivery
Finish comes first when packing this stainless steel fitting: interleaving, individual bags or trays are chosen by finish type, in sealed cartons on export pallets, documented and marked to your instruction.
