Valves, flanges require adiabatic, how to apply the valuation form
(1) Pipe valves, flanges need to be insulated (except silicate smear materials and fiber-like bulk materials), apply the corresponding items of cotton mat (by) products, only change the unvalued materials, The amount of works is calculated according to calculation rules. (2) ventilation pipe flange insulation: ventilation pipe insulation has been considered, shall not be counted. (3) Adiabatic components of ventilation ducts: In the calculation of heat insulation of ventilation ducts, the length of the valves and other components shall not be deducted, and the ventilation ducts adiabatic items shall be calculated according to the extension meters.
Orifice flanges are widely used in conjunction with orifice meters for measuring the rate of flow of liquids and gases. They are basically the same as standard welding neck, slip on and screwed flanges except for the profision of radial, tapped holes in the flange ring for meter connections and additional bolts to act as jack screws to facilitate seperating the flanges for inspection or replacement of the orifice plate.
