Photovoltaic diffusion quartz tubes
Huzhou Aohui Quartz Technology Co., Ltd. ↗Aohui offers diffusion quartz tubes for solar-cell furnaces and can also rework damaged quartz. The listing gives a name and a photo, so the order is built from your furnace interface and process conditions.
Diffusion tube family. Wafer boats, windows and other quartz parts in the Aohui catalogue are separate lines on a quotation.
General illustration of cell production equipment, not a photograph of this model. Ask the manufacturer for current photographs and layout drawings of the configuration offered.
START WITH YOUR PRODUCTION TASK
Send the furnace model and your controlled tube drawing. Tubes sold under the same name can differ in size, end form, ports and gas flow, so the drawing decides the part. The tube encloses the doping step of cell production, so its condition shows up in every batch that passes through.

Matching an Aohui tube to your furnace
Four points decide whether a quoted tube will fit and survive in your furnace.
| Requirement | What you specify | What Aohui should return before approval |
|---|---|---|
| Tube geometry | Length, diameters, wall thickness, ends and ports. | A dimensioned drawing with tolerances for the offered tube. |
| Furnace arrangement | Mounting, supports and gas-flow connections. | Fit sign-off from whoever designed the furnace. |
| Material and cleanliness | Required grade, impurity records and clean packing. | Material and preparation records linked to the lot. |
| Thermal and chemical duty | Process temperature, ramps, gases and cleaning chemicals. | Written application limits for that tube. |

Boats and tubes
The 1600-piece long boat and 1200-piece rhombic boat say nothing about the tube's bore, wafer format, slot layout or installed capacity. Send the drawings of the boat and tube you actually pair together. Include the loader that carries boats into the tube, since wafer handling clearances depend on the bore.
Exhaust tube, flow plate and door
These are listed one by one. Agree whether your order includes them, and check how their connections and supports line up with your equipment.
Cleaning tanks and bottles
Aohui also sells wet-process vessels. The tube's cleaning chemistry, contamination tolerance and fitness after repair still need settling for the tube itself.

Receiving the tube
Fix the drawing
Settle dimensions, ports and any deviations before Aohui starts work, and file the tube revision with the purchase order.
Name the material records
List the documents that must travel with this quartz tube. A general company certificate is no substitute.
Agree inspection
Set the measurement points, visual defect limits and any leak test you need.
Check marking and packing on arrival
Match the records to the tube in the crate and deal with any damage before it goes into the furnace.

New Aohui tube or repaired tube
Buying new
Ask for the material record, drawing and inspection report for the tube Aohui makes. Ask for any lifetime figure in writing, since none is published.
Sending a tube for repair
Describe its condition on arrival and mark the area to be repaired. Agree repair acceptance, any reduced limits and who reinstalls it. Expect a repaired tube to perform to whatever limits Aohui sets for it, which may differ from a new one.

Common questions about the Aohui tube
Can I read purity or temperature limits from the photo?
No. Ask Aohui for the material record and a written operating range for the tube it offers.
Does the tube come with a wafer boat?
No. Aohui sells boats separately, so list every item and its interfaces in the quotation.
