vortex flowmeter castings for industrial process control

vortex flowmeter castings are suitable for prototype validation, small-batch production, and integrated delivery together with subsequent precision machining.

Key features of vortex flowmeter castings:

1. Internal flow-field optimization: Strict control of the measurement cavity, bluff body (throttling element) and radial dimensions to ensure the stability and repeatability of vortex shedding, guaranteeing flow measurement accuracy.
2. Excellent thermal and pressure resistance: Wall thickness and material are designed according to operating conditions to ensure long-term stable operation under steam, high-temperature, or high-pressure environments.
3. Corrosion and wear resistance: Options include stainless steel, ductile (nodular) cast iron, copper alloys, etc., or surface anti-corrosion treatments to handle chemical, seawater, and abrasive media.
4. Installation- and connection-friendly: Provision of flange faces, locating-pin holes, threaded holes and sealing grooves to facilitate rapid on-site installation, sealing and instrument interfaces.
5. Surface- and machining-friendly: After casting, flange faces can be milled flat, holes machined, and internal cavities mirror-polished or ground to reduce on-site adjustment work.
6. Customizable: Support customization based on customer drawings or 3D models, offering core boxes, coring structures and localized rib reinforcement designs to meet special load or pipeline-interface requirements.

Materials and processes:

We support a variety of metal materials, including stainless steel (304, 316, 316L), ductile (nodular) cast iron, gray cast iron, copper alloys and aluminum alloys. Common processes include sand casting, precision (investment) casting and low-pressure casting, combined with necessary heat treatments (ageing, annealing) and stress-relief operations to ensure dimensional stability and mechanical properties for long-term service.

Accuracy and surface quality:

1. Dimensional and geometric tolerances: Flange flatness, concentricity and hole-position tolerances can be controlled according to drawing requirements; critical measurement cavities and flange interfaces can achieve high precision.
2. Internal cavity surface quality: Low surface roughness can be achieved through molding-sand selection, mold polishing or subsequent machining (grinding, polishing) to reduce turbulence interference and measurement error.
3. Sealing face treatment: Flange sealing faces can be produced as RTJ, flat face, or raised face with varying machining accuracy and roughness requirements to support different sealing types.

Typical application scenarios:

vortex flowmeter castings are widely used in industrial process control fields such as heating and steam systems, water supply and wastewater treatment, chemical and petrochemical processes, oil and gas transmission, HVAC systems, power generation and boiler systems, anywhere reliable flow measurement and durable structures are required.
