About this product
Product information from the supplier.
The ASME B16.5 Threaded Flange is a high-precision industrial pipe fitting engineered for seamless integration using a mechanical screwing mechanism. By pairing internal flange threads with external pipe threads, this solution eliminates the need for welding, making it an indispensable component for pipeline systems that require frequent disassembly, routine maintenance, or rapid deployment in moderate pressure environments.
Constructed with a robust flange disc and precision-machined sealing faces, our threaded flanges ensure leak-proof performance and exceptional structural integrity. Whether transporting water, oil, or gas, these fittings provide a reliable, cost-effective connection that maintains high safety standards while offering the flexibility needed for complex industrial structural metal configurations.

Frequently Asked Questions
Q: What is the primary difference between NPT and NPSM threads in flanges?
NPT (National Pipe Tapered) threads create a seal through the tapered interference fit, whereas NPSM (National Pipe Straight Mechanical) threads are straight and typically require a gasket for a leak-proof seal.
Q: Can threaded flanges be used in high-vibration environments?
Threaded joints can be susceptible to loosening under severe vibration. We recommend adding specialized supports or locking devices to ensure stability in such environments.
Q: Which material is best for corrosive chemical environments?
Stainless steel (Grade 304 or 316) is highly recommended for corrosion resistance. For extreme conditions, alloy steels or passivation surface treatments should be used.
Q: What is the maximum pressure rating for ASME B16.5 threaded flanges?
Ratings range from Class 150 to Class 2500. While Class 2500 can handle up to PN42.0MPa, the allowable pressure decreases as the operating temperature increases.
Q: Are threaded flanges suitable for high-temperature applications?
Yes, depending on the material. Carbon steel works up to 425℃, stainless steel up to 600℃, and specific alloy steels can withstand even higher temperatures.
Q: Why choose a threaded flange over a welded one for instrumentation pipes?
Instrumentation pipes often require frequent calibration. Threaded flanges allow for quick disassembly without damaging the pipe, making maintenance far more efficient.
