Case Overview
In 2026, our factory supplied a 26-ton order of 1100-O aluminum coil to a pipe manufacturer in Uzbekistan, destined for the production of aluminum plastic composite pipe (PAP / PEX-AL-PEX). The order covered four custom slit sizes — 0.20mm x 49mm, 0.23mm x 61.7mm, 0.28mm x 77mm and 0.35mm x 99mm — reflecting our ability to deliver precision-slit, soft-temper aluminum strip with stable quality for the demanding pipe industry.
Client Background
The buyer is a Central Asian manufacturer specializing in multilayer pipes for water supply, heating and gas applications. Their aluminum plastic composite pipe combines an aluminum core with inner and outer PE layers, requiring an aluminum strip that is fully annealed (O temper) so it can be folded and welded reliably without cracking, while maintaining uniform thickness and clean edges.
Project Requirements
- Product: Aluminum coil / strip
- Alloy & Temper: 1100-O (soft, fully annealed pure aluminum)
- Quantity: 26 tons
- Application: Aluminum plastic composite pipe (PAP / PEX-AL-PEX)
- Slit sizes required:
| No. | Thickness | Width |
|---|---|---|
| 1 | 0.20mm | 49mm |
| 2 | 0.23mm | 61.7mm |
| 3 | 0.28mm | 77mm |
| 4 | 0.35mm | 99mm |
Product Solution
We produced the coils from 1100 pure aluminum in the fully annealed O temper, then precision-slit them into the four widths requested by the client. Strict thickness tolerances and burr-free edges ensured the strip could be formed, overlapped and welded on the client's pipe production line without rejection.
Why 1100-O Aluminum for Aluminum Plastic Composite Pipe
1100 aluminum contains more than 99% aluminum, offering excellent formability, corrosion resistance and thermal conductivity. The O temper gives the strip maximum elongation and softness, which is essential for the folding and ultrasonic welding steps in composite pipe manufacturing. Because the aluminum core acts as both a barrier and a structural layer, consistent thickness and a clean, uniform surface directly affect the pressure rating and long-term reliability of the finished pipe.
Delivery & Results
- 26 tons of 1100-O coil produced and precision slit into 4 sizes
- Uniform thickness and burr-free edges verified before shipment
- Shipped on seaworthy wooden pallets and delivered on schedule
- Passed the client's incoming inspection with no quality complaints
Customer Feedback
The client confirmed that the 1100-O strip formed cleanly and welded reliably on their composite pipe line, with stable dimensions across all four widths. They valued our accurate slitting, competitive factory direct price and dependable delivery, and indicated interest in further orders for their growing pipe production.
Looking Forward
This Uzbekistan project demonstrates our capability to serve the Central Asian pipe industry with soft 1100-O aluminum coil, custom slit widths and reliable bulk supply. For manufacturers of aluminum plastic composite pipe seeking 1100-O strip in sizes such as 0.20mm x 49mm, 0.23mm x 61.7mm, 0.28mm x 77mm or 0.35mm x 99mm, we welcome the opportunity to quote and supply.
