Plate Flange Manufacturers Stainless Steel Orifice Flange Metal Flange Plate

Core Features

  • Dual-Core Functionality: Multi-engineered to serve either as a streamlined, space-saving Plate Flange for standard pipeline joining or as a high-precision Orifice Carrier Ring for process flow measurement and restriction.
  • Premium Stainless Steel Metallurgy (304 / 316): Finished from fully certified raw stock—offering Grade 304 for standard moisture resistance and Grade 316 (with added Molybdenum) for absolute defense against chloride pitting and acid corrosion.
  • Hubless, Low-Profile Geometry: Completely flat, collarless configuration that slips over the outer diameter of the pipe. This architecture minimizes raw material consumption, drastically lowers freight costs, and optimizes compact equipment layouts.
  • Double Fillet Weld Attachment: Designed to slide over the pipe end and secure via both internal and external fillet welds. This dual-welded matrix evenly distributes physical strain and resists continuous pipeline vibrations.
  • Precision CNC Sealing Surface: Machined on state-of-the-art multi-axis lathes to achieve absolute face flatness and precise phonographic serrations (Ra finish) for maximum gasket friction and blowout protection.

At Kriloha Gaskets & Hardware, we recognize that modern processing networks require components that combine standard pipeline security with specialized process versatility. As a premier Plate Flange Manufacturer, our production line represents our engineered answer for “Multi-Functional-Joint-Security” and “Uncompromised-Flow-Control.” Operating from our high-precision fabrication facility, Kriloha bridges the gap between raw metallurgy and exact geometric perfection, ensuring every plate flange functions flawlessly alongside your sealing gaskets.

The engineering of our stainless steel orifice and plate program is founded on Material-Purity and Structural-Uniformity. Rather than relying on lower-cost, unpredictable casting techniques that leave hidden internal air pockets, Kriloha utilizes fully certified, hot-forged steel billets. By forcing the internal metal grain flow to trace the flat contour of the plate ring, our components offer exceptional tensile strength. They comfortably withstand high bolt-torque loads across the bolt circle without warping, bowing, or relaxing over time. On our automated CNC turning stations, we meticulously calibrate the internal diameter (I.D.), outer diameter (O.D.), and bolt-hole spacing to ensure error-free field assembly.

Manufacturing these critical pipeline elements involves strict Ultrasonic Flaw Detection, Intergranular Corrosion Testing, and Surface-Roughness (Ra) Verification. We collaborate directly with your original equipment manufacturing (OEM), procurement, and design engineering teams to process bespoke configurations—including non-standard bolt circles, tailored thicknesses, unique bore schedules, and specialized face finishes (such as Flat Face or Raised Face configurations). By choosing Kriloha Gaskets & Hardware as your manufacturing partner, you are investing in a “Future-Proof” industrial alliance that maximizes your installation’s uptime through advanced material science and micro-tolerance engineering.

Primary Use Cases

  • Differential Pressure Flow Metering: Serves as a rugged carrier plate within orifice piping runs, enabling the secure mounting of calibrated orifice discs to calculate the flow rates of gases, steam, or liquid chemicals.
  • Marine & Chemical Processing Utilities: Grade 316 stainless steel plate rings used to connect fluid transport lines handling brackish water, aggressive solvents, and chemical reagents.
  • Hygienic Process Pipelines: Clean utility loops in pharmaceutical, biotech, and food/beverage plants where non-porous stainless steel prevents fluid contamination and survives clean-in-place (CIP) steam washdowns.
  • Commercial HVAC & Chilled Water Loops: Cost-efficient, robust connections for large-scale industrial heating loops, cooling towers, and commercial building risers.
  • Modular Industrial Skids: Compact structural flanges used to connect prefabricated piping manifolds to flat-faced valves, pumps, and storage tanks.

Frequently Asked Questions (FAQs)

What is the functional relationship between a “Plate Flange” and an “Orifice Flange”?

A standard plate flange is a flat ring used to connect two sections of pipe together via a double fillet weld. An orifice flange plate can be used as a heavy-duty carrier ring within an orifice meter assembly. This configuration allows technicians to suspend a calibrated orifice plate disc inside the pipeline to restrict fluid flow and measure differential pressure drops.

Why should a project specify a hubless “Plate Flange” instead of a traditional hubbed flange?

Because a plate flange lacks a raised collar or hub, it uses significantly less raw material during manufacturing. This makes it a highly compact, lightweight, and cost-effective alternative for standard process networks where the extra structural reinforcement of a tapered hub is not functionally required.

What specific welding configuration is required to install this stainless plate flange?

A plate welding flange requires a standard double fillet weld setup for proper installation: one robust fillet weld around the rear side where the plate meets the outer diameter of the pipe wall, and a secondary fillet weld along the inside bore face where the pipe end sits flush with the flange face.

When should I choose Grade 316 over Grade 304 stainless steel for this product?

Grade 304 is highly economical and excellent for freshwater, food-grade utilities, and standard atmospheric applications. Grade 316 contains 2–3% added molybdenum, making it necessary for harsher environments exposed to sea salt, brackish water, or chemical acids where pinhole pitting must be strictly avoided.

Are customized dimensions or material test reports available from Kriloha?

At Kriloha Ltd., quality assurance is completely non-negotiable. Every shipment can be accompanied by comprehensive Material Test Reports (MTRs) confirming exact chemical compositions (Carbon, Chromium, Nickel, Molybdenum content), hardness values, yield/tensile strength data, and explicit compliance with international industrial standards (such as ASME, EN, DIN, or JIS). Furthermore, our flexible CNC machining paths allow us to custom-bore the inner diameter or alter the bolt patterns to match your proprietary CAD models.
