Product Details of the Côte d’Ivoire Order

1. CNAF Gasket FF

• Size: 10″ and 16″
• Standard: JIS 10K
• Thickness: 3mm
• Material: CNAF (Compressed Non-Asbestos Fiber)

The CNAF gaskets are designed to provide reliable sealing under high temperature and pressure conditions. Manufactured using premium-grade non-asbestos fiber materials, they exhibit excellent chemical resistance, thermal stability, and durability-making them ideal for oil, gas, and water pipeline applications.

2. Double-End Stud Bolts with Heavy Hex Nuts (Hot-Dip Galvanized)

• Size: M22×115mm, M24×115mm
• Material: ASTM A193 Grade B7 / ASTM A194 Grade 2H

Each stud bolt is heat-treated, precisely threaded, and zinc-coated through the hot-dip galvanizing process, which enhances corrosion resistance in harsh environments such as coastal or industrial zones.

The ASTM A193 B7 bolts provide high tensile strength and excellent performance under pressure, while the A194 2H nuts ensure secure fastening and stability in flanged connections.
