What Is Pipe Thread?

Pipe threads are designed specifically for connecting pipes and ensuring a tight fit between internal and external threads. These threads come in two primary types: unsealed and sealed, both with a 55-degree angle. They play a crucial role in plumbing, gas lines, and various fluid transport systems. There are two main categories of pipe threads: straight and tapered. Straight threads maintain a constant diameter, while tapered threads narrow towards the end, enhancing sealing capabilities. Common types include NPT (National Pipe Taper), PT (British Standard Pipe Taper), and G (Parallel Pipe Thread). Each serves specific applications, with NPT being prevalent in North America and PT commonly found in Europe. NPT threads are part of the American standard and feature a 60-degree taper. They're often used in high-pressure environments due to their robust design. On the other hand, PT threads, or BSPT, are sealed conical threads with a 55-degree angle, making them ideal for industries requiring precise fittings. The G thread, also at 55 degrees but unsealed, is a cylindrical thread commonly used in low-pressure applications. These threads are distinguished not only by their angle but also by their nominal diameter, measured in inches. For instance, a 1/4-inch thread corresponds to 2 points, simplifying the measurement process for professionals in the field. The distinction between 55-degree and 60-degree threads primarily lies in their application and compatibility with different systems. Historically, the development of these threads dates back to the 19th century. The British Wyeth thread, introduced in 1841, laid the groundwork for modern pipe threads. Over time, standards evolved to meet global demands, leading to the creation of the ISO standards in the mid-20th century. Today, these threads are integral to international trade and are widely recognized across continents.
