NPS (National Pipe Straight) ve NPSM (National Pipe Straight Mechanical) arasındaki temel farklar şunlardır:
- Thread Profile: NPS threads are straight, while NPSM threads have a straight, parallel profile 13.
- Sealing Mechanism: NPS threads rely on external seals like gaskets or O-rings for a leak-proof connection, whereas NPSM threads do not provide significant sealing force themselves 12.
- Applications: NPS is commonly used in high-pressure applications, such as in oil and gas, chemical processing, and power generation industries 3. NPSM is often encountered in hydraulic and pneumatic systems where ease of assembly and disassembly are crucial 1.
- Thread Adaptability: NPSM threads cannot be directly connected to NPT threads without using an appropriate adapter 1.
