Nozzle Array/Manifold for Quenching Systems

Product Specifications

Technical details and manufacturing context for Nozzle Array/Manifold

Definition

The Nozzle Array/Manifold is a critical component within quenching systems, serving as the central distribution hub that organizes multiple nozzles into a structured configuration. It ensures uniform fluid delivery across the target surface by precisely controlling flow distribution, pressure regulation, and spray pattern alignment. This component is essential for achieving consistent cooling rates and preventing thermal distortion during heat treatment processes. The manifold is typically fabricated from stainless steel, carbon steel, or brass, with material selection depending on the quenching medium and environmental conditions. For corrosive environments, stainless steel grades 304 or 316 (per ASTM A240) are commonly specified. The component features a range of technical parameters that must be verified for each specific application. The number of nozzles can vary from 4 to 24, with nozzle spacing between 20 and 100 mm, determining the coverage area and flow distribution. Inlet connection sizes range from 1/4 to 2 inches, conforming to ISO 7-1, and must match existing piping. Operating pressure is typically between 1.0 and 1.6 MPa, per with the note that Total flow rate through the manifold ranges from 10 to 200 L/min, depending on nozzle size. Operating temperature spans -40 to 85°C, requiring appropriate material and seal selection. Weight ranges from 2 to 15 kg, and overall dimensions vary, with length from 200 to 1000 mm. Surface finish, specified as Ra 0.8 to 3.2 µm per ISO 1302, affects fouling resistance. These values are directory reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the intended model and application. Standards listed are procurement references and do not imply certification or compliance of any specific product.

Working Principle

The manifold receives pressurized quenching fluid (typically water, oil, or polymer solutions) from the main supply line and distributes it evenly to multiple nozzle outlets. Through internal channels and pressure-balancing mechanisms, it maintains consistent flow rates across all nozzles, enabling uniform spray coverage and controlled cooling of heated metal components. The design ensures that each nozzle receives the required flow and pressure, preventing hot spots or uneven cooling that could lead to distortion or cracking.
