Iso 6162 China Plate Flange Dn 65 Flange Mild Steel Flange

Iso 6162 China Plate Flange Dn 65 Flange Mild Steel Flange

Core Features

  • ISO 6162 Standard Alignment: Engineered to interface with high-pressure fluid systems governed by International Organization for Standardization specifications, ensuring drop-in dimensional compatibility with matching split-flange clamps and hydraulic component faces.
  • DN65 / 2.5-Inch Nominal Pipe Sizing: Configured with a metric clearance bore optimized to slide seamlessly over standard DN65 (2-1/2″ Nominal Pipe Size) piping, tubes, or hydraulic lines.
  • High-Strength Mild Steel Construction: Forged or stamped from reliable, low-carbon structural mild steel (such as St37.2 or S235JR), providing exceptional weldability and heavy-duty structural yield strength at a highly economical price point.
  • Hubless, Flat-Plate Profile: Features a completely flat, collarless configuration that slips directly over the pipe outer diameter, saving physical installation space and minimizing raw material costs.
  • Double Fillet Weld Structural Integrity: Designed for permanent installation 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.

At Kriloha Gaskets & Hardware, we recognize that modern industrial infrastructure requires balancing absolute mechanical security with structural value. Our Mild Steel ISO 6162 DN65 Plate Flanges represent our engineered answer for “Hydraulic-System-Standard-Compliance” and “High-Density-Joint-Stability.” As a premier supplier of high-performance flow control and pipeline elements, Kriloha utilizes automated multi-axis production workflows to ensure that our hubless plate flanges provide superior mechanical longevity.

The engineering of our ISO 6162 plate flange program is founded on Structural-Uniformity and Geometric-Perfection. Forged from certified mild steel blanks rather than lower-grade cast alternatives, our flanges eliminate internal voids and stress pockets. The refined metal grain structure smoothly traces the flat geometry of the plate ring, providing the structural modulus required to withstand high bolt-torque demands across the bolt circle without bowing or warping. At Kriloha, we precision-machine the flat sealing surface on advanced CNC turning lines, finishing them with micro-grooved phonographic serrations that mechanically grip the gasket matrix to resist blowout under sudden system pressure spikes.

Manufacturing and provisioning these critical utility connection pieces involves strict Dimensional Tolerance Checks, Volumetric Material Inspections, and Face Roughness ($R_a$) Calibration. We collaborate directly with your project engineering and facility maintenance teams to supply precise internal bores tailored to standard metric 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 carbon metallurgy and micro-tolerance engineering.

Primary Use Cases

  • Industrial Hydraulic Oil Lines: Robust connection interfaces for main return and suction lines in large-scale hydraulic power units and factory fluid-distribution loops.
  • Heavy Machinery Fluid Inputs: Secure, space-saving connection plates for integrated fluid loops, pump manifolds, and filtration modules on commercial equipment.
  • Factory Utility & Water Transfer Lines: Economical connection joints for non-corrosive industrial water networks, cooling water loops, and low-pressure drainage headers.
  • Pneumatic & Low-Pressure Gas Distribution: Low-profile joint connections for secondary distribution lines carrying compressed air or inert shielding gases to factory workstations.
  • Modular Process Skids: Compact structural flanges used to connect prefabricated piping manifolds to flat-faced valves, strainers, and storage tanks.

Frequently Asked Questions (FAQs)

What is the explicit relationship between ISO 6162 and a standard “Plate Flange”?

ISO 6162 typically governs 4-bolt split flange connections used extensively in high-pressure fluid power and hydraulic installations (often matching SAE J518 patterns). A hubless plate flange built to these specific dimensional footprints provides a compact welding ring solution that allows standard schedule pipes or hydraulic tubes to bolt cleanly into these specialized components.

Why use 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, making it more compact, lightweight, and cost-effective. It provides a flat, space-saving profile that fits into tight spatial envelopes where bulkier hubbed flanges cannot be physically bolted.

What specific welding configuration is required to install an ISO 6162 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 this mild steel flange protected against environmental rust during transit and storage?

Because mild 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 electro-galvanization depending on your long-term storage and installation environment requirements.

Are Material Test Reports (MTRs) provided with these metal plate 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 (Carbon, Manganese, Silicon content), hardness values, yield/tensile strength data, and explicit compliance with international industrial standards to ensure complete code traceability.
