Q: What's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
Q: How are steel pipes classified based on their thickness?
There are three main categories for classifying steel pipes based on their thickness: Schedule, Nominal Pipe Size (NPS), and Wall Thickness. In North America, the Schedule classification is commonly used and refers to the pipe's wall thickness. It is indicated by numbers like Schedule 10, Schedule 40, and Schedule 80, where a higher number means a thicker pipe. On the other hand, the Nominal Pipe Size (NPS) classification is used internationally and refers to the pipe's inside diameter. It is expressed in inches and is usually followed by a schedule number to indicate the wall thickness. For example, NPS 6 Schedule 40 means a pipe with a 6-inch inside diameter and a wall thickness according to Schedule 40. Additionally, steel pipes can be classified based on their wall thickness in millimeters or inches. This classification provides a more precise measurement of the pipe's thickness and is commonly referred to as the "wall thickness" or "wt" in specifications. The wall thickness is measured from the outside diameter to the inside diameter and can be expressed in various units of measurement like millimeters, inches, or gauge. In summary, steel pipes are classified based on their thickness using different systems such as Schedule, Nominal Pipe Size (NPS), and Wall Thickness. These classifications ensure the selection of the appropriate pipe for specific applications, taking into account factors such as pressure requirements, structural integrity, and compatibility with other system components.
Q: What is the difference between internal threading and external threading of steel pipes?
Internal threading and external threading are two different methods used to create threads on steel pipes. The main difference between them lies in the location of the threads. Internal threading refers to the process of cutting threads on the inside surface of a steel pipe. This method involves using a tool or a die to remove material from the inner diameter of the pipe, creating a helical groove. The resulting threads can be used to connect the pipe to other components, such as fittings or valves. On the other hand, external threading involves cutting threads on the outside surface of a steel pipe. This process usually requires the use of a threading die or a lathe to remove material from the outer diameter of the pipe, leaving behind a helical groove. The external threads allow the pipe to be connected to other components or fittings that have corresponding internal threads. The choice between internal and external threading depends on the specific application and the requirements of the project. Internal threading is often preferred when the pipe needs to be connected to components that have external threads, such as fittings or valves. External threading, on the other hand, is typically used when the pipe needs to be connected to components with internal threads, or when the pipe is intended to be screwed into a threaded hole or coupling. In summary, the main difference between internal threading and external threading of steel pipes is the location of the threads – internal threads are cut on the inside surface of the pipe, while external threads are cut on the outside surface. The choice between these methods depends on the specific application and the type of connections required.
