Asme Ansi En Galvanized Steel Plate Flanges Class 150 1.5 Inch For Machinery

Asme Ansi En Galvanized Steel Plate Flanges Class 150 1.5 Inch For Machinery

Core Features

  • Galvanized Corrosion Defense: Hot-dip or electro-galvanized coating provides a protective zinc barrier that shields the underlying carbon steel from atmospheric moisture, oxidation, and rust, eliminating the need for secondary painting.
  • Dual-Standard Structural Layouts: Manufactured to match the dimensional frameworks of both American ANSI/ASME B16.5 (Class 150) and European EN 1092-1 specifications, ensuring universal drop-in compatibility for machinery manufactured globally.
  • 1.5-Inch Nominal Pipe Size (DN40): Precision-bored to slide seamlessly over standard 1.5-inch outer diameter piping or machine fluid intake tubes.
  • Class 150 Pressure Threshold: Engineered to safely handle internal pressures up to 275 PSI at ambient operational temperatures, providing a highly reliable mechanical joint for mid-tier fluid loops.
  • Hubless Plate Design: The flat, collarless configuration provides a highly compact physical footprint, making it ideal for space-constrained machinery internal layouts and structural skids.

At Kriloha Gaskets & Hardware, we recognize that industrial machinery demands components that combine space-saving efficiency with relentless environmental defense. Our Galvanized Steel 1.5-Inch Class 150 Plate Flanges represent our engineered answer for “Space-Constrained-Security” and “Atmospheric-Oxidation-Defense.” As a premier supplier of high-performance pipeline and flow interfaces, Kriloha utilizes controlled manufacturing and uniform zinc plating to ensure that every plate flange delivers a reliable seal within complex mechanical setups.

The engineering of our galvanized plate flange program is founded on Coating-Uniformity and Geometric-Precision. By utilizing forged carbon steel blanks that undergo high-precision machining before the zinc application, we eliminate the structural porous pockets common in cheap cast alternatives. The zinc layer bonds metallurgically to the steel structure, providing sacrificial protection that prevents rust even if the surface is lightly scratched during machinery assembly. At Kriloha, we verify the absolute flatness of the sealing surface and the precise concentricity of the bolt circle, resulting in “Failure-Resistant” joints that distribute bolt tension uniformly across your machinery gaskets to resist vibration-induced loosening.

Manufacturing and provisioning these precision connection pieces involves strict Dimensional Tolerance Checks, Zinc-Layer Thickness Verification, and Bolt-Hole Alignment Calibration. We collaborate directly with your original equipment manufacturing (OEM) and facility maintenance teams to supply precise internal bores tailored to standard tube gauges or nominal pipe schedules. By choosing Kriloha Gaskets & Hardware, you are investing in a “Future-Proof” industrial partnership that optimizes your machinery’s operational life through superior metallurgy and micro-tolerance engineering.

Primary Use Cases

  • Industrial Machinery Fluid Inlets: Secure, space-saving connection interfaces for industrial washing systems, hydraulic power packs, and lubrication units.
  • Pumping Stations & Skids: Economical, rust-resistant connection points on modular fluid transfer skids and centrifugal pump manifolds.
  • Factory Utility & Compressed Air Lines: Connection points for factory distribution lines carrying compressed air, cooling water, and inert shielding gases.
  • Agricultural & Irrigation Equipment: Corrosion-protected pipeline joints for large-scale agricultural spraying machinery and pumping systems exposed to weather elements.
  • HVAC Chilled Water Loops: Compact mechanical connections for commercial heating, cooling, and ventilation machinery enclosures.

Frequently Asked Questions (FAQs)

What is the advantage of a Galvanized Plate Flange over a standard Carbon Steel flange?

Standard carbon steel flanges are highly vulnerable to rust and require temporary anti-rust oils or continuous painting. Galvanized flanges feature a bonded zinc coating that provides long-term resistance to moisture, salt spray, and industrial environments, making them a maintenance-free, cost-effective choice for machinery assemblies.

Can a Galvanized Plate Flange be welded directly to a pipe?

Yes, but proper safety and engineering protocols must be followed. The zinc coating near the welding zone must be ground off before welding because burning zinc produces toxic galvanized fumes and can cause weld porosity, weakening the joint. Once welded, the bare joint should be coated with a cold-galvanizing zinc-rich paint to restore corrosion protection.

What welding configuration is used to install this hubless plate flange?

A plate flange requires a double fillet weld setup for installation: one robust fillet weld around the rear side where the plate interfaces with the outer diameter of the machine pipe, and a secondary fillet weld along the inside bore face where the pipe end sits flush with the flange face.

Are ANSI Class 150 and European EN 1092-1 plate flanges completely interchangeable?

While their pressure capabilities are comparable for low-to-medium utility applications, their actual bolt patterns, outer diameters, and bolt hole sizes can differ between the American and European metrics. At Kriloha Ltd., we supply specific cross-over dimensions or distinct standard versions to match your machinery’s exact blueprint specifications.

Are Material Test Reports (MTRs) provided for these galvanized flanges?

At Kriloha Ltd., quality assurance is completely non-negotiable. Every shipment can be accompanied by certified Material Test Reports (MTRs) outlining the baseline chemical composition, mechanical test values, and compliance with ANSI/ASME standard specifications to ensure complete industrial traceability.
