Gayatri Tubes is a well-known name in supplying and manufacturing Copper / Brass Compression Tube fittings to its clients. Features of these tubes make them specifically designed for use in instrumentation, process and control systems. These are also used in analyzers and environmental equipment employed in chemical, petroleum. To go with that, many power generation, seawater industries, condensers, offshore industries, petrochemical industries, and pulp and paper plants also make effective use of these tube fittings. Copper Brass Compression Tube Fittings have also been used extensively in other industries wherein high reliability, durable and quality is desirable.
These tube fittings come with high-quality silver plated threads on nuts. High quality ensures the reduction of galling on the body threads. It offers tremendous resistance to all kinds of corrosion in the effects of acids and alkali. It is known for minimal leakage, even in tough working conditions. It works relatively well in high-pressure situations; it is resistant to erosion and works fine even under elevated temperatures. Our compression fittings compress the ferrule between the nuts and pipe carefully. Compression allows for effective sealing and no leakage. With that, these offer vibration resistance as well. The Leak-proof joints of these compression tube fittings can be used in high-pressure vacuum and many vibration applications. Copper / Brass Compression Tube Fittings are very strong and sturdy. One can easily weld it using tungsten gas arc or shielded metal arc welding techniques. These resist the formation of any boundary precipitates on the corners; hence these become excellent for welding purposes. These process applications in chemical-based industries such as food, pharmaceutical make good use of this property of these tube fittings. These tube fittings find use in many industries, including chemical, food and food processing, pharmaceutical, and plastics. In addition to that, these are used in heat exchangers, metal cleaning stuff, pickling equipment, etc.
