15Mm Stainless Steel Plate Flange Pn16

15Mm Stainless Steel Plate Flange Pn16

Core Features

  • 15mm Compact Precision Sizing: Precision-machined with a center bore tailored to slide seamlessly over standard 15mm (approx. 1/2-inch Nominal Pipe Size) stainless steel tubing or conduits, ensuring a close-tolerance fit for small-bore piping networks.
  • Premium Grade Stainless Steel (304/316L): Available 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 and acid-induced stress cracking.
  • PN16 Pressure Standard Compliance: Fully rated to handle continuous fluid and gas working pressures up to 16 Bar (approximately 232 PSI) under standard ambient temperature parameters, meeting strict international utility criteria.
  • Hubless, Low-Profile Geometry: The completely flat, collarless circular profile minimizes component weight, slashes raw material costs, and slips easily into tight, restricted equipment layouts.
  • Double Fillet Weld Architecture: Engineered with a clean clearance bore to facilitate code-compliant internal and external fillet welds, creating a robust, leak-proof mechanical joint that evenly distributes structural strain along the thin-wall tube.

At Kriloha Gaskets & Hardware, we recognize that micro-bore systems demand the exact same engineering integrity as massive primary headers. Our 15mm Stainless Steel PN16 Plate Flanges 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 metric 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, chemical dosing skids, laboratory sampling loops, and localized 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 does the “PN16” designation signify for a 15mm stainless plate flange?

PN16 stands for Pressure Nominal 16 Bar. At standard ambient reference temperatures, a PN16 flange is rated to operate safely at pressures up to 16 bar (~232 PSI). As the operating temperature of the system rises, the maximum allowable working pressure gradually decreases according to the specific stainless steel grade’s rating curve.

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

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 (such as EN 1092-1 Type 01 or DIN templates) to guarantee complete industrial traceability.
