FAQs of SS 347 Forged Fittings:
Q: How are SS 347 Forged Fittings manufactured?
A: SS 347 Forged Fittings are produced through a forging process in which heated stainless steel grade 347 or 347H is shaped under high pressure to achieve the required specifications. This process enhances their strength and grain structure, making them suitable for demanding industrial uses.
Q: What standards do SS 347 Forged Fittings comply with?
A: These fittings conform to several international standards such as ASME B16.11, MSS-SP-79, MSS-SP-83, MSS-SP-95, MSS-SP-97, and BS3799, ensuring reliable quality and consistency for various industrial requirements.
Q: Where are SS 347 Forged Fittings typically used?
A: They are commonly utilized in high-temperature and high-pressure piping systems, particularly in industries like petrochemical, oil and gas, power generation, and chemical processing, where excellent chemical resistance is essential.
Q: When should SS 347H forged fittings be chosen over standard 347?
A: SS 347H forged fittings are specifically selected when applications demand enhanced high-temperature strength, as the H variant features a higher carbon content improving creep resistance and mechanical performance above 500C.
Q: What benefits do socketweld and screwed-threaded fittings offer?
A: Socketweld fittings provide a strong, leak-proof joint suitable for high-pressure applications, while screwed-threaded (NPT/PT) fittings offer easier installation and dismantling, making them ideal for low to medium pressure piping systems.
Q: What is the recommended usage process for these fittings?
A: For optimal performance, ensure precise measurement, prepare the pipes with compatible ends, and follow proper welding or threading procedures as per standards. Regular inspection and proper torque application ensure longevity and safe operation.
