Description


How does a pipe reducer work?
JS FITTINGS reducers reduce the pipe from a larger size to a smaller bore (inner diameter). Alternatively, reducers may refer to any fittings which cause a change in pipe diameter. The change of size may be intended to meet hydraulic flow requirements of the system or adapt to existing piping of a different size. The length of the reduction is usually equal to the average of the larger and smaller pipe diameters. Although reducers are usually concentric, eccentric reducers are used as needed to maintain the top- or bottom-of-pipe level.
A reducer can also be used either as a nozzle or diffuser, depending on the mach number of the flow.

Can your price be lower?
|
Of course. The thickness tolerance of the pipe fittings is ±12.5%, the thickness tolerance of the forged flanges is ±1mm. If the bigger tolerance is acceptable for you, the price can be lower. If you must need the products with standard tolerance, please consider to add the quantity, the more the cheaper.
