What Is Buttweld Pipe Fittings?
Buttweld pipe fittings are components that are used in connecting different piping components within the pipeline. These buttweld fittings are welded directly on the pipe and play a pivotal role in influencing the characteristics of the flow. They can be produced either through hot or cold rolling procedures. The material used in their production can be nickel alloy, super duplex, and 6% moly. In most cases, the material used in the fitting is similar to the component it is welded on. These fittings are available in a range of shapes and dimensions depending, on their applications. The fittings are defined in the ASME B16.9 standards. These corrosion-resistant light-weight fittings are manufactured into MSS SP43.
What Is Weldolet?
A weldolet is one of the most common branching connections. These components act as an outlet between a larger and a smaller piping connection. They help in reducing the concentration of stress on the piping area. These modules are beveled to facilitate easy joining operations and are therefore termed as buttweld fittings. Weldolets generally exhibit the same or higher pipe schedule to the pipe it is supposed to be attached with. It is available in a range of forged material grades namely ASTM A182, A105, A350, etc. The standard dimensions of these components range between 1/4 inch to 36 inches with the run pipe diameter and 1/2 to 2 with the branched diameter.
