Loose Plate Flange EN 1092-1

At UTMK, you can order high-quality Loose Plate Flanges, designed to create reliable and easily maintainable demountable pipeline connections. This flange type features a two-component design, consisting of a backing ring that rotates freely on the pipe and a separate weld-on collar, which significantly simplifies the installation process by allowing for easy alignment of bolt holes. This design is particularly effective in confined spaces and for sections that require regular maintenance.

Technical Specifications

Loose Plate Flanges manufactured by UTMK comply with stringent industry standards and are suitable for operation in a variety of conditions. The key technical parameters are summarized in the table below, allowing engineers and procurement specialists to quickly verify product compliance with project requirements. We guarantee full conformity to the stated specifications and provide all necessary certification documents.

Advantages of Loose Plate Flanges

Loose flanges offer a range of unique design advantages that provide operational and economic efficiency across a broad spectrum of industrial applications. Choosing this type of connection helps optimize both the installation process and the subsequent operation of piping systems.

• Simplified and Accelerated Installation. The key benefit is the ability of the flange to rotate freely around the pipe before the collar is welded. This completely eliminates bolt hole misalignment issues, allowing for faster installation with less labor, especially in hard-to-reach areas.


• Optimized Total Cost of Ownership. The design allows the use of standard carbon steel flanges (S235JRG2, St20) in systems transporting corrosive media. Only the weld-on collar, which is in direct contact with the medium, needs to be made from expensive, corrosion-resistant alloys, while the flange itself remains a cost-effective standard part.


• Ideal for Systems Requiring Frequent Maintenance. The ability to easily disassemble and reassemble the connection without cutting or re-welding makes these flanges indispensable for pipeline sections with filters, valves, or measurement equipment that require regular inspection or replacement.


• Enhanced System Reliability and Longevity. The two-piece design reduces the transfer of bending stress from the pipe to the bolted connection. This improves the joint's resistance to vibration and can extend the service life of the entire piping system, contributing to supply chain stability and reduced operational risk.

Application Areas

Due to their versatility, reliability, and ease of installation, Loose Plate Flanges are widely used in various industrial and municipal sectors. They are a standard solution for creating demountable joints in both new and modernized piping systems, ensuring full technical compliance and certification.

• Industrial Piping Systems. For the construction and maintenance of process pipelines in the chemical, petrochemical, and energy sectors. They are used in accordance with the requirements for components in metallic industrial piping systems as per standard EN 13480.


• Water and Wastewater Management. Connecting sections of main and distribution networks, as well as installing pumps, valves, and filtration equipment. Installation complies with regional building codes and water management standards.


• HVAC and Fire Protection Systems. Assembling large-diameter pipelines for heating, ventilation, air conditioning, and automated fire suppression systems in large commercial and industrial buildings.


• Shipbuilding and Marine Applications. Used in on-board piping systems for transporting technical fluids, where resistance to vibration and the ability for quick repairs in confined spaces are critical.


• Agricultural and Irrigation Projects. Connecting main irrigation lines, pump stations, and filtration units where easy assembly and disassembly for seasonal maintenance are beneficial.
