XGLG throttling device - rectangular Venturi tube：

Rectangular Venturi tubes are commonly used in air supply pipelines (welded with thin iron plates), and can be used to measure air volume (such as power plant suction, supply, and heating furnace supply). According to the structure of the shrink tube, it can be divided into two types: single-sided shrink type and double-sided shrink type.

Main characteristics of rectangular Venturi tube：
The structure is lightweight, easy to transport, and can also be assembled on site.

Easy to produce and low cost (compared to classic Venturi tubes).

Low pressure loss and energy conservation.

Main technical parameters of rectangular Venturi tube:
◆ Inlet equivalent diameter (equivalent to nominal diameter) (mm): D=1.13 ≤ 0.25. In the formula, W: the width of the inlet pipe (rectangular); H: Height of inlet pipe (rectangular)
◆ Nominal pressure (MPa): ≤ 1200
Accuracy (inaccuracy): ± 5%
