Navgraha Steel & Engg Company is a manufacturer and supplier of SS 347 Fittings. These are components connecting pipes and piping system elements widely used in several types and forms in multiple piping applications. These are installed for the conveyance of fluids in the proper direction and controlled flow with leak lock existence. These fittings include elbows, stubend, reducers, crosses and tees with other components made from SS 347 grade. Thus it reveals grade properties with the efficiency of performance. It is available in various standards, specifications and sizes. At the same time, it has types furthermore according to shape, connection and classifications. Our fittings are offered in excellent strength and superior quality at lower costs.
• Stainless steel SS 347:
SS 347 is commonly used for wide thermal applications. It is enhanced quality austenitic grade by the accumulation of columbium and tantalum. Thus it shows:
• Brilliant resistance to inter-granular corrosion
• Strongly opposing oxidizing surroundings
• Increased corrosion defiance
• High tensile strength and lower maintenance cost
Therefore these fittings are excellent working in oxidizing media as well as upper-level temperatures. SS 347 is stabilized alloy with tantalum and chromium contents. It is suitable for the annealing process at a higher temperature range since columbium tends to have repetitive heating.
• How does SS 347 Fittings work?
These fittings offer excellent inter-granular corrosion resistance by eliminating carbide precipitation. In addition, these fittings present the following qualities.
• Provides excellent creep and stress rupture opposition.
• Effective against corrosion
• Avoids rust and pitting.
• Defend against chlorides and acids decay
These are recommended for a higher range of heat and chemical manufacturing since it avoids corrosion effects in heat and chemicals such as chlorides and acids as well as other reducing compounds. Our Fittings are praised for superb strength, excellent corrosion resistance as well as weldability and durability. These are easy to form and flexible. Higher and lower pressures are allowed to apply on these fittings.
• Where are SS 347 Fittings employed?
These Fittings are applied at several applications in piping systems, including marine, oil and gas, chemical, Textile industry and several other sectors like:
• Furniture
• Pharmaceutical
• Nuclear
• Dairy and Food Industry
• Waste Hose Systems
