Asme A182 Forged Stainless Steel Pl Flange Dn 50 Steel Flange Plate

Core Features

  • ASME A182 Standard Compliance: Precision-manufactured in strict accordance with the American Society for Testing and Materials (ASTM) A182 specification, the global benchmark for forged alloy and stainless steel piping components designated for high-temperature and corrosive service.
  • DN50 / 2-Inch Nominal Pipe Sizing: Configured with a metric clearance bore optimized to slide seamlessly over standard DN50 (2″ Nominal Pipe Size) industrial pipelines, facilitating precise field layout alignment.
  • Forged Microstructural Integrity: Hot-forged under controlled thermal conditions to ensure a refined, continuous metal grain flow. This eliminates internal air pockets, voids, and casting porosities, providing a high burst-pressure threshold under systemic load.
  • Space-Saving Hubless Geometry (PL): Features a completely flat, collarless plate profile. This layout requires less raw material, drastically reducing the component’s weight and cost while fitting easily into space-restricted equipment enclosures.
  • Double Fillet Weld Attachment: Engineered to slide over the pipe end and secure using both internal and external fillet welds. This dual-welded matrix evenly distributes physical strain along the joint and minimizes vibration fatigue.

At Kriloha Gaskets & Hardware, we recognize that a pipeline is only as secure as its bolted interfaces. Our ASME A182 Forged Stainless Steel DN50 Plate Flanges represent our engineered answer for “High-Density-Joint-Security” and “Flawless-Flat-Alignment.” As a leading manufacturer and supplier of integrated fluid handling and sealing interfaces, Kriloha utilizes automated multi-axis production workflows to ensure that our hubless plate flanges provide superior mechanical longevity.

The engineering of our A182 plate flange program is founded on Metallurgical-Traceability and Surface-Precision. By forcing the steel’s internal grain structure to trace the flat contour of the plate ring, our components offer exceptional tensile strength. This ensures the flange comfortably withstands high bolt-torque demands across the bolt circle without warping, bowing, or relaxing over time. At Kriloha, we precision-machine the flat sealing surface on advanced CNC turning centers, finishing them with micro-grooved phonographic serrations that mechanically grip your choice of gasket sheets to resist blowout under sudden system pressure spikes.

Manufacturing and provisioning these critical flow-control connection pieces involves strict Dimensional Tolerance Checks, Volumetric Material Inspections, and Face Roughness ($R_a$) Calibration. We collaborate directly with your project engineering and facility procurement teams to supply precise internal bores tailored to standard pipe outer diameters and specific wall-thickness schedules. By choosing Kriloha Gaskets & Hardware, you are investing in a “Future-Proof” industrial partnership that prioritizes your system’s lifetime reliability through superior stainless metallurgy and micro-tolerance engineering.

Primary Use Cases

  • Hygienic Process Piping: Ideal for transport lines in food processing, beverage production, and dairy plants where stainless steel surfaces stand up to regular clean-in-place (CIP) washdowns.
  • Chemical Fluid Transfer: Secure connections for process lines handling mildly corrosive chemicals, organic solvents, and industrial reagents.
  • Water Treatment & Desalination: Standard connection interfaces for municipal water filtration networks, reverse osmosis skids, and wastewater treatment loops.
  • HVAC & Chilled Water loops: Premium, rust-resistant connections for commercial building risers, industrial condenser loops, and cooling utilities.
  • Modular OEM Machinery Skids: Compact structural flanges used to connect prefabricated piping manifolds to flat-faced valves, strainers, and storage tanks.

Frequently Asked Questions (FAQs)

What is the significance of the “ASME A182” specification?

ASME A182 is the global industry standard for forged or rolled alloy and stainless steel pipe flanges, forged fittings, and valves intended for high-temperature and corrosive applications. Sourcing an A182 flange ensures the material has been rigorously tested for grain structure, tensile strength, and metallurgical purity.

Why use a hubless “Plate Flange” instead of a traditional hubbed Slip-On flange for a DN50 line?

Because a plate flange completely lacks a raised collar or hub, it uses less raw material, making it significantly more compact, lightweight, and cost-effective. It provides a flat, space-saving profile that fits into tight spatial envelopes where bulkier hubbed flanges cannot be physically bolted.

What specific welding configuration is required to install an A182 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 grades is this ASME A182 flange typically supplied?

It is most commonly provisioned in Grade F304/304L for general corrosion resistance in water, food, and standard atmospheric applications, or Grade F316/316L (molybdenum-bearing) for superior defense against chloride pitting and crevice corrosion in marine or aggressive chemical environments.

Are Material Test Reports (MTRs) provided with these flanges?

At Kriloha Ltd., quality assurance is completely non-negotiable. Every shipment from our facility can be accompanied by comprehensive Material Test Reports (MTRs) confirming the exact chemical compositions, hardness values, heat treatment logs, yield/tensile strength data, and explicit compliance with international industrial standards.
