Core Features

  • Premium Stainless Steel Metallurgy (304/316L): Available in high-purity Grade 304 for exceptional resistance to atmospheric moisture and freshwater environments, or low-carbon Grade 316L for premium defense against chemical acids, chloride pitting, and intergranular weld-zone oxidation.
  • Universal Drop-In Dimensional Alignment: Precision-machined to adhere strictly to major international standardized frameworks—including American ASME/ANSI B16.5 (Class 150), European EN 1092-1 (Type 01), and German DIN 2576 templates—ensuring exact bolt-hole and alignment compatibility.
  • Space-Saving Hubless Geometry: Features a completely flat, collarless circular profile that slides directly over the end of the pipe or tube. This design minimizes raw material volume, slashes structural component weight, and optimizes tight spatial envelopes.
  • Micro-Tolerance Flat Face (FF) Sealing: Precision-turned on automated multi-axis CNC lathes to achieve absolute parallel face alignment. Finished with standardized micro-grooved phonographic serrations that maximize gasket friction and block fluid bypass.
  • Double Fillet Weld Architecture: Engineered with a clean clearance bore to facilitate code-compliant internal and external fillet welds, creating a robust, leak-proof joint that evenly distributes structural pipeline tension.

At Kriloha Gaskets & Hardware, we recognize that an industrial pipeline is only as reliable as its bolted interfaces. Our Standard Stainless Steel Flat Plate Flanges represent our engineered answer for “Zero-Leak-Security” and “Uncompromised-Joint-Alignment.” As a premier supplier of high-performance fluid handling and sealing interfaces, Kriloha utilizes controlled manufacturing and precision multi-axis CNC machining to ensure that our hubless plate rings provide maximum physical resilience alongside your chosen gasket matrix.

The engineering of our stainless plate flange program is founded on Metallurgical-Traceability and Sharp-Geometric-Precision. By forcing certified stainless steel stock through controlled forging paths rather than relying on lower-cost casting alternatives, we eliminate internal gas pockets, voids, and structural micro-cracks. The refined metal grain structure smoothly traces the flat geometry of the plate ring, providing the structural modulus required to withstand high bolt-torque demands across the bolt circle without warping or bowing over time. At Kriloha, we meticulously finish the flat mating face with standardized concentric micro-serrations, creating an aggressive mechanical grip that anchors the gasket sheet firmly in place to resist blowout under sudden system pressure surges.

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, procurement, and facility maintenance teams to supply precise internal bores tailored to standard pipe outer diameters or specific wall-thickness schedules (such as Schedule 10S or 40S matching). 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 Pipelines: Ideal for routing fluids in food processing, dairy bottling lines, cosmetics, and beverage facilities where smooth, non-porous stainless surfaces withstand aggressive washdowns.
  • Corrosive & Marine Utilities: Secure connection joints for seawater cooling networks, desalination skids, reverse osmosis modules, and offshore utility piping loops.
  • Chemical Handling & Dosing Skids: High-integrity flanged interfaces for process lines transporting mild acids, industrial reagents, organic solvents, and wastewater treatment chemicals.
  • Commercial HVAC & Chilled Water loops: Premium, lifetime rust-resistant connections for commercial building risers, cooling tower headers, and industrial condenser circuits.
  • Modular OEM Machinery Skids: Compact structural connection rings used to integrate prefabricated manifold piping to flat-faced valves, strainers, and storage tanks.

Frequently Asked Questions (FAQs)

What is the fundamental definition of a “Plate Flange” compared to other flange types?

A plate flange (often designated as an EN 1092-1 Type 01 or a slip-on plate ring) is a completely flat circular disk with no extended collar, raised hub, or tapered welding neck. It functions by sliding directly over the outer diameter of the pipe and is secured to the pipeline using a double fillet weld configuration, making it the most compact and economical flange design available.

Why specify a hubless Flat Plate Flange instead of a traditional hubbed Slip-On flange?

Because a plate flange completely lacks a raised collar, 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 tapered hub is not functionally required.

What specific welding configuration is required to install a 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 flat face.

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

Grade 304 is highly economical and excellent for freshwater, food-grade utilities, and standard atmospheric applications. Grade 316L contains 2–3% added molybdenum and ultra-low carbon content, making it mandatory for harsher environments exposed to sea salt, brackish water, or chemical acids where pinhole pitting and weld-zone intergranular corrosion 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, hardness values, yield/tensile strength data, and explicit compliance with international industrial standards. 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.
