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. - 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. - Applications: NPS is commonly used in high-pressure applications, such as in oil and gas, chemical processing, and power generation industries. - Thread Adaptability: NPSM threads cannot be directly connected to NPT threads without using an appropriate adapter.
