Steel Flange Plate Din Ansi 150Lb Pn16

Steel Flange Plate Din Ansi 150Lb Pn16

Core Features

  • Cross-Standard Blueprint Alignment: Precision-engineered to bridge the gap between American ANSI/ASME B16.5 (Class 150) and European DIN / EN 1092-1 (PN16) dimensional layouts. This dual-matching footprint guarantees absolute bolt-pattern, pitch circle, and alignment interchangeability across global utility networks.
  • Hubless, Structural Plate Geometry: Features a space-saving, completely flat collarless ring 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.
  • High-Strength Steel Core Options: Fabricated from premium, hot-forged carbon steel (such as ASTM A105 or St37.2) for heavy-duty structural rigidity, or finished in high-grade stainless steel (304/316) for ultimate corrosion defense.
  • Double Fillet Weld Securement: Designed to be permanently attached to the pipeline using both internal and external fillet welds, creating a robust, leak-proof mechanical joint that evenly distributes structural strain and helps absorb systemic pipeline vibrations.
  • 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 or torque loss over time.

At Kriloha Gaskets & Hardware, we recognize that modern engineering often demands cross-compatible solutions that eliminate inventory redundancy. Our Dual-Standard ANSI 150lb / DIN PN16 Steel Flange Plates represent our engineered answer for “Universal-Standard-Interchangeability” and “High-Density-Joint-Stability.” As a premier supplier of high-performance flow control and pipeline elements, Kriloha utilizes automated fabrication lines to deliver drop-in, hubless plate rings that align perfectly with multi-national project blueprints.

The engineering of our dual-certified plate flange program is founded on Structural-Uniformity and Geometric-Perfection. Forged from certified raw steel stock rather than lower-grade cast alternatives, our flanges completely eliminate internal voids, gas pockets, and structural stress concentrations. 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 undergoing structural relaxation over time. At Kriloha, we precision-machine the flat sealing surface and finish them with controlled phonographic serrations that mechanically grip your choice of gasket matrix 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, procurement, and facility maintenance teams to supply precise internal bores tailored to standard pipe outer diameters and unique 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 metallurgy and micro-tolerance engineering.

Primary Industrial Applications

  • Transcontinental Utility Networks: Ideal for cross-border projects where equipment, valves, and pumps sourced from different regions (American vs. European standards) must cleanly interface.
  • Municipal Water & Sewage Infrastructure: Standard connection joints for large-scale water filtration plants, heavy municipal pump manifolds, and wastewater treatment headers.
  • Commercial HVAC & Cooling Loops: Cost-efficient, highly reliable connections for large-scale industrial heating loops, open/closed cooling towers, and building water risers.
  • Industrial Utility Compressed Air Lines: High-density flat interfaces for factory-wide compressed air networks, nitrogen distribution loops, and vacuum systems.
  • Modular OEM Machinery Skids: Compact structural flanges used to connect prefabricated piping manifolds directly to flat-faced valves, strainers, and storage vessels.

Frequently Asked Questions (FAQs)

How can a single steel flange plate comply with both ANSI 150lb and DIN PN16 standards?

While ANSI (American) and DIN/EN (European/Metric) are entirely separate standards, certain nominal mid-bore piping sizes share nearly identical bolt counts, bolt-hole diameters, and pitch circle spacings. By precisely calibration-machining the tolerances, these specific flanges can be dual-certified to meet both standards seamlessly, allowing international operators to standardize their replacement inventories.

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

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 pipe wall, and a secondary fillet weld along the inside bore face where the pipe end sits flush with the flange face.

How is a carbon steel flange plate protected against environmental rust during transit?

Because carbon steel is vulnerable to atmospheric oxidation, our flanges come standard with a protective surface treatment. This typically includes a light yellow or black anti-rust lacquer, a rust-preventative oil finish, or hot-dip galvanization depending on your long-term storage and field installation environment requirements.

Are Material Test Reports (MTRs) provided with these steel flange plates?

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, hardness values, yield/tensile strength data, and explicit compliance with international dimensional standards to guarantee complete industrial traceability.
