Key Features & Benefits of Dipti Metal Industries' PTFE Coated Fasteners

Dipti Metal Industries' PTFE (Xylan / Fluoropolymer) coated stud bolts, nuts, and washers are engineered for superior performance and reliability in aggressive industrial conditions. Here are the key features and benefits:

• Exceptional Corrosion Resistance: The PTFE coating provides a robust barrier against a wide range of corrosive agents, including saltwater, acids, alkalis, and industrial chemicals, often outperforming traditional platings. This significantly extends the service life of fasteners.
• Low Coefficient of Friction: PTFE is known for its extremely low friction properties, which translates to a reduced and consistent tightening torque. This ensures accurate preload during installation and prevents galling (cold welding) between mating threads, making assembly smoother.
• Anti-Galling and Anti-Seizing: The inherent lubricity of the PTFE coating prevents metal-to-metal contact, eliminating galling during installation and ensuring easier, non-destructive removal of fasteners even after prolonged exposure to harsh conditions.
• Wide Operating Temperature Range: Our coated fasteners maintain their integrity and performance across a broad spectrum of temperatures, typically from -195°C (-320°F) to +260°C (+500°F), suitable for both cryogenic and high-temperature applications.
• Chemical Inertness: The fluoropolymer coating is highly resistant to most industrial chemicals, solvents, and fuels, ensuring the fasteners remain unaffected and reliable in chemically aggressive environments.
• Prevents Galvanic Corrosion: When joining dissimilar metals, PTFE coating acts as an insulating barrier, effectively preventing galvanic corrosion that can occur with untreated fasteners.
• Diverse Substrate Material Grades: We offer fasteners in various high-strength steel grades suchs as ASTM A193 B7, B16, B8, B8M, and ASTM A320 L7, paired with appropriate nut grades like ASTM A194 2H, GR7, GR8, GR8M, GR16, ensuring suitability for a multitude of pressure and temperature services.
• Adherence to International Standards: All our PTFE coated fasteners are manufactured and coated in strict compliance with major international standards including ASTM, ASME, DIN, ISO, and often NACE MR0175/ISO 15156 for sour service applications.

Technical Specifications: Dipti Metal Industries' PTFE Coated Fasteners

Our PTFE (Xylan / Fluoropolymer) coated stud bolts, nuts, and washers are produced to stringent technical specifications, guaranteeing optimal performance and compliance with global industry standards.

These specifications ensure our PTFE coated fasteners are suitable for high-integrity, corrosion-resistant applications in the most demanding industrial environments. We provide comprehensive technical data and certification for every order.

PTFE / Fluoropolymer Coating Characteristics

Our PTFE and fluoropolymer coatings, including brands like Xylan, are specifically chosen and applied for their exceptional properties, which significantly enhance the performance and longevity of industrial fasteners. These characteristics make them indispensable for critical applications:

• Superior Corrosion Protection: The coating creates a highly effective barrier against various corrosive elements, including harsh chemicals, saltwater, and atmospheric exposure, dramatically extending the life of the fasteners and the bolted joint.
• Consistent Low Coefficient of Friction: PTFE is inherently slippery. This characteristic ensures that the coefficient of friction is consistently low and uniform, allowing for precise and accurate torque application during assembly. This reduces the risk of over-tightening or under-tightening, leading to a more reliable clamp load.
• Anti-Galling and Anti-Seizing Properties: The non-stick nature of fluoropolymers prevents metal surfaces from "cold welding" together. This is crucial for preventing galling during installation and for ensuring that fasteners can be easily removed, even after prolonged service in corrosive or high-temperature environments.
• Broad Temperature Stability: These coatings perform reliably across a wide temperature spectrum, from cryogenic lows (e.g., -195°C) to elevated temperatures (up to +260°C), making them versatile for diverse industrial processes.
• Chemical Inertness: Fluoropolymer coatings are highly resistant to degradation from a vast array of chemicals, including strong acids, bases, solvents, and fuels. This inertness ensures the coating remains intact and protective in chemically aggressive settings.
• Dielectric Strength: The coating acts as an electrical insulator, which can be advantageous in preventing galvanic corrosion between dissimilar metals in a bolted connection, further enhancing overall integrity.
• UV Resistance: Many fluoropolymer coatings also exhibit excellent resistance to ultraviolet (UV) radiation, making them suitable for outdoor and exposed applications without degrading.

These combined properties ensure that Dipti Metal Industries' PTFE coated fasteners provide a robust, long-term solution for demanding fastening applications, offering unmatched reliability and cost-effectiveness.
