The following are the types of pipe ends:
1. Plain End (PE)A plain end is cut square with no special profile or angle. It’s typically used with slip-on couplings or sleeve couplings sized to the pipe’s outer diameter. This end type is ideal for direct welding and is commonly found in low-pressure water lines and general construction.
2. Beveled End (BE)A beveled end features a cut at a 30°–37.5° angle, preparing the pipe for butt welding. This bevel allows better weld penetration, resulting in a strong, reliable joint. Beveled ends are widely used in oil, gas, geothermal, high-pressure water systems, and infrastructure projects that demand permanent, leak-free connections.
3. Threaded End (TE)Threaded ends are machined with standard NPT (National Pipe Taper) or BSP (British Standard Pipe) threads to mate with threaded fittings like couplings, elbows, or flanged threaded connectors. They’re popular in low- to medium-pressure gas and water installations, such as sprinkler systems, because they install without welding and are ideal for small-diameter pipes requiring periodic maintenance.
By understanding each end type’s characteristics, you can choose the right steel pipe for your welding, mechanical, or threaded connections. The proper end type speeds up installation, boosts joint strength, and minimizes leaks.
