Flange Pl Pipe Plate Flange Plate Flange For Welding Orifice Flange Manufacturers

Flange Pl Pipe Plate Flange Plate Flange For Welding Orifice Flange Manufacturers

Core Features

  • Dual-Core Processing Utility: Multi-engineered to serve either as a streamlined, space-saving Plate Flange (PL) for standard pipeline joining or as a high-precision Orifice Carrier Ring for process flow restriction and differential pressure monitoring.
  • 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 component weight, and optimizes space within tight equipment layouts.
  • Double Fillet Weld Structural Attachment: Designed to slide directly 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 structural vibrations.
  • Precision CNC Sealing Face: Machined on state-of-the-art multi-axis CNC lathes to achieve parallel face alignment. Finished with standardized micro-grooved phonographic or concentric serrations ($R_a$ finish) for maximum gasket friction and blowout protection.
  • Multi-Standard Dimensional Compliance: Precision-fabricated to align with major international piping frameworks—including American ASME/ANSI B16.5, European EN 1092-1 (Type 01), and German DIN 2576 templates—ensuring exact bolt-hole and matching alignment compatibility.

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 multi-purpose PL program is founded on Material-Purity and Structural-Uniformity. Rather than relying on lower-cost, unpredictable casting techniques that leave hidden internal air pockets or structural micro-voids, 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 under pressure 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, Volumetric Material Inspections, and Surface-Roughness ($R_a$) 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, or specialized pressure tap layouts. 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 Industrial Applications

  • Differential Pressure Flow Metering: Serves as a rugged carrier plate within orifice piping runs, enabling the secure mounting of calibrated orifice discs to calculate or regulate the flow rates of gases, steam, or liquid chemicals.
  • Municipal Water & Waste Utilities: Standard connection interfaces for large-scale water filtration plants, heavy sewage drainage networks, and municipal pumping stations.
  • Commercial HVAC & Cooling Loops: Cost-effective, robust connections for large-scale industrial heating loops, open/closed cooling towers, and commercial building water risers.
  • Pneumatic & Industrial Gas Distribution: Low-profile joint connections for primary factory loops carrying compressed air, nitrogen, or argon to heavy production machinery.
  • Modular OEM Machinery Skids: Compact structural flanges used to connect prefabricated piping manifolds to flat-faced valves, storage tanks, and strainers.

Frequently Asked Questions (FAQs)

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

A standard PL plate flange is a flat circular ring used to connect two sections of pipe together via a double fillet weld configuration. An orifice flange plate can be adapted from this identical hubless profile to serve as a 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 Flat Plate Flange instead of a traditional hubbed flange?

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

What specific welding configuration is required to install this type of 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.

In what material selections is this product typically provisioned?

Depending on your application environment, Kriloha supplies these components in ASTM A105 / St37.2 Carbon Steel (finished with anti-rust lacquer or galvanization) for non-corrosive water, oil, and gas lines, or Stainless Steel 304 / 316L for clean utility lines, food-grade processing, or aggressive chemical flow networks.

Are customized dimensions or material test reports available from Kriloha?

At Kriloha Ltd., quality assurance is completely non-negotiable. Every shipment from our facility can be accompanied by comprehensive Material Test Reports (MTRs) confirming exact chemical compositions, 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.
