Lap Joint Stub Ends provide some advantages in piping systems. They are versatile and economical means of making connections, particularly in systems where there will need to be frequent disassembly to perform maintenance. The stub end design allows for easy and reliable alignment with the stub end and then welding, so the remaining parts are joined together and leak free. Ideal when using lap joint flanges, the stub end provides options, by facilitating differing orientations relating to the installation of the lap joint flange to the stub end, so the stub end is not at risk of misalignment with the flange. More than merely offering options with installation and versatility, it is important to highlight that lap joint stub ends offer an increased level of corrosion resistance and are also very good for moderate and high-pressure applications, as is typical of oil and gas, chemical, and power generation applications.

Lap Joint Stub Ends are a great option for piping systems and are commonly used in industries that require ease of disassembly for cleaning or maintenance. They are typically used in the chemical processing, oil and gas, and power generation industries. The design of lap joint stub ends allows a flanged connection to align easily with another component. They are the right choice for service situations where recurring maintenance of the line is required or in which connections need to be adjusted without disturbing the entire system. They can be used for any high-pressure and/or high-temperature service because they are durable.
