As a leading manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been producing high-quality industrial sealing solutions since 1998. Our Industrial Copper Sealing Strip (1mm x 30mm) is specifically engineered for chemical equipment flange sealing, offering superior corrosion resistance and reliable compression under extreme conditions. With an annual export value exceeding US$5 million, we serve diverse markets across North America, South America, Europe, and Asia, ensuring that our products meet the rigorous demands of the chemical industry.
This copper sealing strip is crafted from premium-grade copper (C1100/C1020), providing excellent thermal conductivity and ductility. The precise 1mm thickness and 30mm width are optimized for standard flange grooves, delivering a tight seal that prevents leakage of aggressive chemicals, gases, and high-pressure fluids. Whether used in heat exchangers, reactors, or piping systems, this strip ensures long-lasting performance even in temperatures up to 400°C (752°F).
Key Features & Technical Specifications
- High-Quality Copper: Made from C1100 (electrolytic tough pitch copper) or C1020 (oxygen-free copper) – optional upon request.
- Precision Dimensions: 1mm thickness (±0.05mm tolerance) and 30mm width (±0.5mm) ensure consistent fit.
- Excellent Corrosion Resistance: Withstands exposure to acids, alkalis, and organic solvents commonly found in chemical plants.
- Good Compressibility: Soft annealed state allows the strip to deform under flange pressure, filling irregularities.
- Customizable Length: Available in continuous rolls (e.g., 10m, 20m, 50m) or cut-to-length pieces.
- No Burrs or Sharp Edges: Surface is smooth and clean, reducing installation risks.
