Ceramic Fluoropolymer Stud Bolt utilizes ASTM A193 B16 high-strength alloy steel certified to API 20E BSL-1 standards. Its innovative dual-layer coating system combines a ceramic aluminum base layer for extreme temperature resistance and a fluoropolymer top layer for superior corrosion resistance and chemical inertness. Designed for highly corrosive environments such as LNG cryogenic pipelines, chemical reactors, and offshore platforms, it ensures long-term sealing integrity with zero maintenance costs.
Core Advantages of Ceramic Fluoropolymer Stud Bolt
