Weld Tube Fittings
A pipe fitting is defined as a part used in a piping system, for changing direction, branching or for change of pipe diameter, and which is mechanically joined to the system called Weld tube fittings. There are many different types of fittings and they are the same in all sizes and schedules as the pipe.
Weld tube fittings whose dimensions, dimensional tolerances are defined in the ASME B16.9 standards. Light-weight corrosion resistant fittings are made to MSS SP43. Weld tube fittings and KF fittings, CF fittings and ISO fittings has the similarities and differences. not only using in the vacuum field but also can using in other industrial field.
