A threaded flange is a specialized hydraulic connector component featuring precision-machined threads that mate with corresponding threads on pipes, valves, or other hydraulic elements. It serves as a mechanical interface that creates a sealed, pressure-resistant joint in hydraulic systems, typically used in applications where disassembly is required for maintenance or component replacement. The flange portion provides a flat sealing surface for gaskets or O-rings, while the threads ensure mechanical engagement and alignment.

定义
A threaded flange is a specialized hydraulic connector component featuring precision-machined threads that mate with corresponding threads on pipes, valves, or other hydraulic elements. It serves as a mechanical interface that creates a sealed, pressure-resistant joint in hydraulic systems, typically used in applications where disassembly is required for maintenance or component replacement. The flange portion provides a flat sealing surface for gaskets or O-rings, while the threads ensure mechanical engagement and alignment.
工作原理
The threaded flange operates on the principle of mechanical thread engagement combined with compressive sealing. When tightened, the threads draw the flange faces together, compressing a gasket or seal between them to create a fluid-tight barrier. The threads provide axial force to maintain compression, while the flange distributes this force evenly across the sealing surface. This dual mechanism ensures both mechanical connection integrity and hydraulic sealing under pressure.

常见问题

What is the difference between NPT and BSPP threaded flanges?

NPT (National Pipe Taper) threads are tapered and seal through thread interference, while BSPP (British Standard Pipe Parallel) threads are parallel and require a separate sealing washer or O-ring. NPT is common in North America, BSPP in Europe and Asia.

How do I prevent leakage in threaded flange connections?

Use proper thread sealant (like PTFE tape or liquid thread sealant for NPT), ensure correct torque specification, use undamaged threads, and replace worn gaskets. For BSPP threads, always use the specified sealing washer.

Can threaded flanges be used in high-pressure hydraulic systems?

Yes, when properly specified. High-pressure applications require higher grade materials (like alloy steel), proper thread engagement length, and adherence to pressure ratings. Always verify the flange's pressure rating exceeds system requirements.
