Disadvantages of ASME B16.11 Union
Threaded joints are most likely the oldest way of connecting piping systems. Threaded fittings, especially Socket Weld Union, are typically utilised for small pipe diameters.Due to uneven heat transfer between the pipe and connections, rapid temperature changes could result in leaks.
Because of the high stress effects induced by the sharp grooves at the foot of the threads, vibrations can cause deformations.
Threaded connections must be eliminated in hazardous plumbing systems if at all possible. Their susceptibility to fatigue damage is substantial, particularly where visible threads are corroded.
How To Install A Socket Weld Union
Before welding, the pipe is put into the pipe to create a socket weld fitting. The pipe is then pushed out a limit of 1/16" to provide for thermal movement of the tube. If this space is not left, the pipe may expand against the valve and cause the weld to split.
A ASME B16.11 Union is a pipeline connector feature that involves inserting a tube into a flange's depressed area. Socket weld fittings, as opposed to buttweld fittings, are generally used for small tube diameters.It is suitable for use in pipelines having a nominal diameter of NPS 2 or below.
Why are Stainless Steel Threaded Union so strong?
The Stainless Steel Threaded Union is the popular fitting used to connect thin-walled pipes in sewage and electric conduit networks. These fittings are extremely resistant to severe pressures and temperatures. They work well with strong fluids and pressure fittings. The ASTM A182 Hammer Union is employed in flow lines to avoid piping system leaks. These unions can withstand pressures of up to 20.000 psi and are material traceable. They are commonly used in muck tanks, petroleum & energy pipework, and other similar applications. The SS Barrel Union is employed to facilitate maintenance access by splitting the line. The blocking nut is fitted onto a pipe, enabling for the removal of a piece of the pipe for repairs.
