SS 316 Flanges offered by Navgraha Steel & Engg Company are mainly employed for better corrosion resistance and excellent strength demanding applications. Several industries, including fluid transmissions and manufacturing sectors, are widely utilizing flanges of different types. These flanges types commonly known are orifice, slip-on, lap-joint, ring joint, etc. It is welded or threaded in the system to assemble with a raised, flat face, or other connection types. SS 316 Flanges are an excellent choice for corrosive applications and minimize chloride pitting and crevice corrosion. In comparison, low carbon SS 316L Flanges are improved to a higher resistance against several corrosive environments.
Stainless Steel SS 316 features are:
• Austenitic Steel
• Outstanding Strength
• Outstanding Defiant to Erosion
• Crevice Strength and Pitting Resistance
SS 316 Flanges are excellently strengthened and tough. It provides excellent assembling features among accuracy and precision of structure. It unites pipes and other assemblies in piping systems with ease of connection due to excellent weldability. In addition, It provides a point for inspection or cleaning of the piping system. These are additionally recommended for marine applications, excluding warmth brine. Otherwise, it is effective in several other corrosive environments.
SS316L Flanges avoids inter-granular corrosion at sections affected by welding heat. These Flanges are formed with excellent grades offering high strength to corrosion cracking in high loads. Therefore It is flexible and long-lasting, with excellent functioning in severe conditions. It is applied at higher pressures through piping flow and provides various pressure capabilities of different classes.
SS 316L Flanges are known for:
• Mechanical Strength
• Tensile Strengths
• Thermal Expansion
• Toughness
SS 316 Flanges are accessible in several types, sizes, and dimensions in several application systems. It is available in standard and custom sizes. Moreover, it is retaining excellent tensile and yield strength with good thermal conductivity. We offer these flanges at favorable rates with quality assurance. In addition, it is recommended for intermittent use at higher temperatures to gain excellent oxidation temperatures, excluding continuous use. SS 316 Flanges are packed with proper packing material and distributed with secure transit.
