Tube Plate Flange Din Ansi 150Lb Pn16 Pipe Stainless Steel

Tube Plate Flange Din Ansi 150Lb Pn16 Pipe Stainless Steel

Core Features

  • Dual-Standard Compatibility Options: Engineered to bridge international piping specifications, available in dimensions compliant with either American ANSI/ASME B16.5 (150Lb) or European DIN/EN 1092-1 (PN16) standards for seamless global integration.
  • Matched Pressure Ratings: Universally rated for low-to-medium pressure installations, safely managing operational limits up to 275 PSI for ANSI 150Lb or 16 Bar for DIN PN16 systems under ambient temperature conditions.
  • Hubless Tube-Plate Design: Features a completely flat, collarless configuration that slips over the outer diameter of the tube or pipe, allowing for clean, space-saving installations and straightforward dual fillet welding.
  • Premium Corrosion-Resistant Alloys: Finished from certified, fully traceable Grade 304 or Grade 316 stainless steel stock, delivering superior protection against rust, oxidation, and chemical pitting.
  • Precision CNC Face Sealing: Precision-turned sealing faces ensure uniform gasket seating and parallel mechanical mating, preventing fluid bypass and minimizing torque loss over time.

At Kriloha Gaskets & Hardware, we understand that global projects demand cross-border component compatibility. Our Tube Plate Flanges (ANSI 150Lb / DIN PN16) represent our engineered answer for “Dual-Standard-Versatility” and “Space-Optimized-Joint-Security.” As a premier supplier of high-grade industrial pipeline elements, Kriloha manufactures these hubless plate flanges to deliver maximum mechanical efficiency in tight configurations where bulky hubbed flanges cannot fit.

The engineering of our dual-standard plate flange program is founded on Metallurgical-Traceability and Geometric-Precision. Forged from premium raw steel billets rather than lower-grade castings, our tube-plate flanges exhibit uniform material density and exceptional tensile strength. By utilizing state-of-the-art multi-axis CNC turning lines, we guarantee absolute face flatness. At Kriloha, we precision-machine the required sealing surface—whether your application calls for a flat face (FF) or a standard raised face (RF) with phone-line serrations—resulting in “Failure-Resistant” connections that mechanically lock the gasket matrix into place under high bolt torque.

Manufacturing and provisioning these critical high-grade elements involves strict Dimensional Tolerance Checks, Volumetric Material Inspections, and Border-Pattern Alignment Verification. We collaborate directly with your project engineering and facility maintenance teams to supply precise internal bores tailored to standard tube gauges or nominal pipe sizes (NPS/DN). By choosing Kriloha Gaskets & Hardware, you are investing in a “Future-Proof” industrial partnership that optimizes your system’s structural longevity through superior metallurgy and micro-tolerance engineering.

Primary Use Cases

  • Industrial Tube & Pipe Plumbing: Ideal for utility networks distributing industrial water, low-pressure gases, and non-aggressive fluid systems.
  • Commercial HVAC Infrastructures: Connection joints for large-scale heating, cooling, and air conditioning loops in commercial properties and factories.
  • Water & Wastewater Treatment: Secure flange connections for municipal water supply lines, filtration systems, and effluent treatment facilities.
  • Food, Beverage & Dairy Process Lines: Hygienic tube connections where the non-porous, smooth surface of stainless steel stands up to regular clean-in-place (CIP) chemicals.
  • Light Chemical & Petrochemical Transfer: Budget-friendly, reliable joints for transfer pipelines handling mild chemical reagents, oils, and organic solvents.

Frequently Asked Questions (FAQs)

What is the difference between a Tube Plate Flange and a standard Slip-On flange?

A tube plate flange is completely flat and lacks the raised hub or collar found on a standard slip-on flange. It slides over the tube or pipe and is welded flush with the pipe end. This profile makes it highly space-efficient and cost-effective for standard low-to-medium pressure systems.

Are ANSI 150Lb and DIN PN16 plate flanges dimensionally identical?

No, they are different standards. While their pressure ratings are functionally comparable (150Lb is roughly 20 bar at ambient, while PN16 is 16 bar), their bolt hole circles, outer diameters, and bolt counts often vary. At Kriloha Ltd., we manufacture distinct versions for both standards to ensure a perfect mechanical match with your existing equipment.

What welding methodology is required for a Tube Plate flange?

A tube plate flange requires a double fillet weld setup: one robust fillet weld on the rear side of the plate where it meets the outer diameter of the tube wall, and a secondary weld on the inside face where the tube end interfaces with the flange bore.

When should I choose Grade 316 over Grade 304 stainless steel for this flange?

Grade 304 is highly economical and excellent for freshwater, food-grade utilities, and standard atmospheric applications. Grade 316 contains 2–3% added molybdenum, making it essential for harsher environments exposed to sea salt, brackish water, or chemical acids where pinhole pitting must be strictly avoided.

Can Kriloha provide custom inner bore diameters for non-standard tubes?

Yes. While we stock standard sizes matching commercial pipeline schedules, our flexible CNC machining lines allow us to custom-bore the inner diameter to match your proprietary tube gauges or unique structural dimensions without extensive tooling delays.
