Import Expanded Graphite With Inconel Wire Inserted — Buy in Bulk from Supplier in China

This expanded graphite sheet incorporates a continuous Inconel 600 wire mesh embedded at intervals to reinforce mechanical integrity under high pressure and thermal stress. The graphite matrix is expanded to a carbon purity of approximately 99%, with the wire inserted at 10mm to 20mm spacing to prevent tearing during compression. The product is supplied in continuous lengths of 20 meters per roll, designed for industrial gasketing applications requiring structural resilience.

The Inconel wire provides tensile reinforcement without compromising the thermal and chemical resistance of the graphite. Standard Inconel 600 has a melting point of 1350°C and maintains strength up to 1000°C, making it suitable for use in high-temperature valve and flange seals. The composite material retains the flexibility of pure expanded graphite while resisting delamination under cyclic loading. Typical bulk density of the graphite layer is 0.15 to 0.25 g/cm³.

Primary users include manufacturers in oil and gas, chemical processing, and power generation who require gaskets for high-pressure valves and heat exchangers. Buyers often specify this product for applications exceeding 320 bar pressure or temperatures above 1000°C. Packaging is in sealed plastic tubes with cardboard outer cases. Trade terms are typically FOB Ningbo, with MOQs based on roll quantity and lead times of 20 to 40 days depending on customization.

Ningbo Auto Sealing Technology Co., Ltd is located in Cixi, Ningbo, Zhejiang Province, China, with a registered address on Hua Sheng Road. The company is categorized as an imported-tier supplier, suggesting it has prior export experience. Its listing indicates specialization in sealing materials, particularly composite gaskets. No details are provided about factory size, workforce, or certifications, and no client references or production capacity figures are disclosed.

The supplier's focus appears limited to expanded graphite products with metal reinforcement. There is no public evidence of laboratory testing, ISO certification, or in-house R&D. Response metrics are unavailable, and no contact information beyond the address is listed. Buyers should assume this is a manufacturer without verified quality systems and must request independent testing before bulk procurement.
