DIN Slip-on Flanges

Reliable Flange Connections for Industrial Piping Systems

DIN Slip-On Flanges are manufactured in accordance with DIN (Deutsches Institut für Normung) standards, offering a dependable and economical solution for connecting pipes, valves, pumps, and other equipment. Designed to slide over the pipe before welding, these flanges are secured with fillet welds on both the inside and outside, providing excellent alignment, reliable sealing, and strong mechanical performance. Their straightforward installation and standardized dimensions make them a preferred choice for a wide range of industrial piping applications.

Premium Materials and Precision Manufacturing

Our DIN Slip-On Flanges are produced from high-quality carbon steel, stainless steel, alloy steel, duplex stainless steel, and other engineered materials to meet various operating requirements. Advanced forging technology, precision CNC machining, controlled heat treatment, and strict dimensional inspections ensure superior strength, accurate tolerances, and smooth sealing surfaces. Every flange is manufactured in compliance with DIN specifications to ensure full compatibility with European and international piping systems.

Excellent Strength, Durability, and Sealing Performance

Designed for long-term industrial operation, DIN Slip-On Flanges provide outstanding resistance to pressure, temperature fluctuations, corrosion, and mechanical stress. The double fillet weld design enhances structural integrity while ensuring stable sealing performance under demanding operating conditions. When used with suitable gaskets and fastening systems, these flanges help minimize leakage, reduce maintenance requirements, and improve overall pipeline reliability.

Comprehensive Size and Pressure Range

Our DIN Slip-On Flanges are available in a complete range of DN sizes, with pressure ratings including PN6, PN10, PN16, PN25, PN40, PN63, and PN100, depending on application requirements. Various sealing face designs, bore dimensions, flange thicknesses, and drilling patterns are available to suit different piping systems. Customized materials, special machining, protective coatings, and non-standard dimensions can also be manufactured according to customer drawings and technical specifications.

Wide Industrial Applications

DIN Slip-On Flanges are widely used in oil and gas, petrochemical processing, chemical plants, water treatment facilities, municipal water supply, wastewater management, power generation, marine engineering, district heating systems, HVAC installations, food and beverage processing, pharmaceutical manufacturing, pulp and paper industries, and general industrial pipeline networks. Their easy installation, cost efficiency, and dependable performance make them suitable for both new construction and maintenance projects.

Comprehensive Quality Assurance

Every DIN Slip-On Flange undergoes rigorous quality inspections throughout the manufacturing process. Raw material verification, chemical composition analysis, mechanical property testing, dimensional inspection, hardness testing, non-destructive testing (NDT), surface examination, and final visual inspection are carried out to ensure compliance with DIN standards and customer specifications. Additional inspection services, including ultrasonic testing, magnetic particle testing, and third-party certification, are available upon request to satisfy project requirements.
