Introduction of Lap Joint Stub End Buttweld Fittings

A lap joint stub end is a type of Buttweld fitting used in piping systems to facilitate easy assembly and disassembly of flanged connections. It's typically used in situations where frequent maintenance, cleaning, or inspection of the piping system is required. The lap joint stub end consists of two main components: the stub end and the lap joint flange.

1 Stub End:The stub end is a short length of pipe with one end machined to match the outer diameter of a certain pipe size, while the other end has a slightly larger diameter that allows it to slide over the pipe. This allows for easy alignment and connection with the pipe. The stub end does not have a flange on its end; instead, it has a weld bevel that allows it to be Butt-welded to the pipe.

2 Lap Joint Flange:The lap joint flange is a separate component that is attached to the end of the stub end. It consists of a flat, circular plate with bolt holes around its circumference. This flange is not welded to the pipe but rather to the stub end, short type, allowing for rotational movement and easy alignment during assembly. The lap joint flange is then bolted to another flange (typically a raised face flange or a flat face flange) of a different material or size.

The key advantages of lap joint stub end buttweld fittings include:

  • Easy Alignment and Assembly: The rotational flexibility of the lap joint connection allows for easy alignment of flanges, which is particularly beneficial when dealing with pipes of different materials or sizes.
  • Reduced Galvanic Corrosion: The separation between the stub end and the flange helps reduce the risk of galvanic corrosion that can occur when dissimilar metals are in direct contact.
  • Cost-Effectiveness: The ability to only replace the stub end when it's worn out or damaged, without having to replace the entire pipe, flange, or valve, can lead to cost savings.
  • Versatility: Lap joint stub end fittings are versatile and can be used in a wide range of applications, including systems that require frequent disassembly for maintenance or cleaning.
  • Minimized Stress Transfer: The lack of flange-to-pipe welding minimizes stress transfer to the piping system, which can be important in high-temperature or high-pressure applications.

However, it's important to note that lap joint connections are not as strong as fully welded connections. They are generally used in low-pressure and non-critical applications where the ease of maintenance and alignment outweighs the need for a fully welded joint. When selecting a joint type, factors like system pressure, temperature, material compatibility, and maintenance requirements should all be considered.
Keep in mind that industry standards and practices may change over time, so it's recommended to refer to the latest codes and standards when working with piping systems and fittings.

A Stub End fitting is a short length of pipe with one flared end and the other end needing to be welded to the pipe of the same size. A combination of stub ends and backing flanges is an alternate way of joining pipes compared to the use of standard flanges. The use of stub ends reduces the weight of the flanged joints. The stub ends allow quick disconnection of the particular section involved. Stub ends are installed in pairs and mated together with two lap joint flanges.

These can also be used in high pressure pipelines. The stub ends do not get in contact with the fluid conveyed by the pipeline. Stub ends allow sections of the line to be opened without the need to re-weld. Savoy Piping Inc. is a quality buttweld Stub End Supplier.
