15Mm Stainless Steel Flange Plate

15Mm Stainless Steel Flange Plate

Core Features

  • 15mm Small-Bore Precision Sizing: Engineered with a compact center bore optimized to slide seamlessly over standard 15mm metric tubing or conduits (approximately 1/2-inch Nominal Pipe Size), ensuring a close-tolerance fit for small-bore fluid lines.
  • Premium Stainless Steel Matrix (304/316L): Sourced in high-purity Grade 304 for standard moisture resistance and food-grade utility lines, or low-carbon Grade 316L for ultimate defense against chloride pitting, stress-corrosion cracking, and aggressive industrial chemicals.
  • Hubless, Space-Saving Profile: Features a completely flat, collarless circular geometry. This minimalist ring profile eliminates unnecessary raw metal volume, drastically slashes total component weight, and fits easily into tight mechanical footprints.
  • Precision CNC Sealing Face: The flat mating face is precision-turned on multi-axis CNC machines to achieve parallel joint alignment and uniform gasket compression, preventing fluid bypass, pressure loss, or torque relaxation over time.
  • Double Fillet Weld Attachment: Designed to slide over the pipe end and secure via both internal and external fillet welds. This dual-welded matrix creates a robust, leak-proof mechanical joint that evenly distributes physical line tension.

At Kriloha Gaskets & Hardware, we recognize that micro-bore systems demand the exact same engineering integrity as massive primary headers. Our 15mm Stainless Steel Flange Plates represent our engineered answer for “Micro-Space-Structural-Security” and “Flawless-Flat-Alignment.” As a premier supplier of high-performance flow control and mechanical hardware interfaces, Kriloha produces these compact hubless plate adapters to deliver maximum mechanical versatility within tight spatial footprints.

The engineering of our 15mm stainless steel program is founded on Metallurgical-Purity and Sharp-Geometric-Tolerance. Forged or stamped from certified raw material blanks rather than lower-grade cast alternatives, our flanges eliminate the internal micro-voids and stress pockets that lead to catastrophic failures under pressure. The refined metal grain structure smoothly traces the flat profile of the plate ring, providing the structural modulus required to withstand high bolt-torque demands across the bolt circle without bowing, warping, or relaxing under pressure over time. At Kriloha, we precision-machine the flat sealing face on advanced CNC turning centers, finishing them with micro-grooved phonographic serrations that mechanically grip the gasket matrix to resist blowout under sudden system pressure cycles.

Manufacturing and provisioning these critical high-grade components involves strict Dimensional Tolerance Checks, Intergranular Corrosion Testing, and Surface-Roughness ($R_a$) Calibration. We collaborate directly with original equipment manufacturers (OEMs), chemical engineers, and facility maintenance teams to supply precise internal bores tailored to standard metric tube gauges or threaded pipe profiles. 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

  • Small-Scale Machinery Fluid Loops: Compact connection interfaces for industrial hydraulic packs, localized chemical dosing skids, laboratory sampling loops, and lubrication manifolds.
  • Hygienic Process Micro-Pipelines: Clean utility networks in food processing, beverage bottling lines, dairy plants, and cosmetics manufacturing where surfaces must withstand aggressive washdowns.
  • Pneumatic & Low-Pressure Gas Distribution: Low-profile joint connections for factory secondary branch lines carrying compressed air, nitrogen, or argon directly to automated assembly workstations.
  • Commercial HVAC & Condensate Drainage: Premium, lifetime rust-resistant connections for routing thin-wall chilled water lines, commercial condenser loops, and air-handling drainage tubes.
  • Modular Industrial Utility Skids: Space-saving mechanical flanges used to connect small prefabricated utility piping segments directly to flat-faced valves, miniature pumps, and instrument manifolds.

Frequently Asked Questions (FAQs)

What is the explicit advantage of a hubless “Plate Flange” over a traditional hubbed flange for a 15mm line?

Because a plate flange completely 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 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 tube wall, and a secondary fillet weld along the inside bore face where the tube end sits flush with the flange face. For thin-walled 15mm tubes, high-strength TIG welding is recommended to prevent burn-through.

What standard bolt patterns are available for this 15mm flange?

While dimensions can be customized to match proprietary CAD drawings, our 15mm plate flanges are typically machined to match standard compact metric layouts (such as minor DIN/EN patterns) or imperial ANSI Class 150 (1/2-inch nominal sizing) bolt circles to ensure seamless field integration with existing valves and instruments.

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 Material Test Reports (MTRs) provided with these small-bore 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 exact chemical compositions (including Carbon, Chromium, Nickel, and Molybdenum content), hardness values, yield/tensile strength data, and explicit compliance with international dimensional standards to guarantee complete industrial traceability.
