Dosch - Restriction Orifice Plates
Restriction orifice plates for effective pressure regulation. To achieve a defined pressure reduction in the processes of your plants or blowout lines, restriction orifice plates are indispensable. A restriction orifice plate is suitable for all single-phase media, for their transport, processing, and forwarding. Restriction orifice plates, also known as a flow restriction orifice, reduce pressure or limit flows in your facilities during regular operations, but also in case of emergencies. Therefore, they are primarily used in the oil and gas industry, the chemical sector, and power plants. However, restriction orifice plates also prove themselves in general plant construction. In specific cases, restriction orifice plates can also be used for throughput limitation.
At Dosch, we specialize in the design and manufacturing of restriction orifice plates, especially for use in critical applications which involves high-pressure losses, flow velocities, or a risk of cavitation. We provide precise and reliable solutions. Restriction orifice sizing depends on the requirements of the application. Customize restriction orifice plates for your application with us. Rely on our decades of experience.
- Cost-effective: Restriction orifice plates are more affordable than alternatives, even in applications with higher wear.
- Customizable: We design our restriction orifice plates specifically according to your requirements and process conditions.
- Durable: When the correct restriction orifice plate is selected for specific requirements, it is characterized by longevity and reliability.
- Versatile: Restrictions are suitable for different media, making them a versatile solution in various industries.
Restriction orifice plate design can be different: restriction orifice plates can be delivered as a simple insert disc with an attached handle shield for installation between pipeline flanges with different sealing surfaces, or as a weld-in variant. The bore is generally cylindrical. Stelliting or other hardening of the restriction bore is possible with certain materials to achieve a longer lifespan. For special applications, this can also be eccentrically arranged. multi hole restriction orifice and multi stage restrictions are used when, for example, limits for sound or pressure are required.
We will be pleased to supply you additionally with the correspondingly required pipe flanges, screws and gaskets.
