Sheet thickness
The indicated thicknesses are theoretical thicknesses. However, Steekflens will always use the standard trade plate thicknesses. As a result, the thickness of the blindspades could end up being higher than the theoretical thicknesses.
When machining the flanges (e.g. gasket surfaces), Blindspades and Spectacle blinds can be delivered in 2 (welded) parts.
Welding complies with ASME B 16.48-2010 chapter 4.1
Orifice
Order your orifice flange here. We custom make these for you, so they are only available upon request. Clicking on the DIN or ANSI version will take you to the order form where you can specify what material, diameter, pressure class, gasket surface, bore type, bore diameter and quantity you would like.
What is an orifice?
An orifice is a special type of flange with an opening in the center. The flange is used to measure and/or regulate the flow of liquid, steam or gas in a pipe system. It does so by reducing the passage of a pipe and thus creating a difference in pressure. The orifice is also used to perform accurate flow measurements, because the hole in the flange (the orifice) has an absolute, exact size, allowing flow calculations to be performed more accurately. Orifices are used in pressure testing, strength testing and pressure regulation.
