Haihao Group Supplies ANSI B16.5 F316L Blind Flanges and ASME B16.20 316L Spiral Wound Gaskets for Global Project
Haihao Group, a trusted name in pipeline equipment, has recently fulfilled an order for ANSI B16.5 F316L blind flanges and ASME B16.20 316L spiral wound gaskets to a client operating in the international energy sector. This shipment underscores our expertise in delivering corrosion-resistant, high-performance components for critical industrial applications.

ANSI B16.5 F316L Blind Flange
The order includes F316L blind flanges in sizes 2″, 3″, 4″, and 6″, available in both 150# and 300# pressure ratings. Paired with these flanges are 316L spiral wound gaskets in thicknesses ranging from 0.5” to 2.5”, ensuring leak-free connections in demanding environments.
ANSI B16.5 F316L blind flanges are engineered to seal pipeline ends securely. Their 316L stainless steel composition provides exceptional resistance to corrosion, making them suitable for chemical, oil and gas, and marine projects. The flanges meet ANSI B16.5 standards, guaranteeing precision in dimensions and pressure tolerance.
Completing the package are ASME B16.20 316L spiral wound gaskets. These gaskets combine 316L stainless steel windings with flexible filler materials, creating a durable seal even under extreme temperatures and pressures. The variety of sizes—0.5” to 2.5”—ensures compatibility with diverse flange configurations.
