Double Flange Carbon Steel Ductile Iron PN10 16 25 40 Dismantling Joint

This double-flanged dismantling joint is engineered for superior performance and reliability in pipeline systems. Its core body is constructed from high-strength ductile iron, offering an exceptional combination of toughness, durability, and resistance to impact and bending stresses. The incorporation of carbon steel flanges ensures maximum structural integrity and a perfect, high-pressure seal when bolted to the pipeline.

Key features include its ability to accommodate axial compression and extension, which is crucial for absorbing pipeline movement and simplifying installation and maintenance. The joint allows for easy insertion or removal of equipment like valves and pumps without requiring extensive pipe displacement. The high-grade EPDM or NBR seals ensure a leak-proof performance across a wide pressure range, certified for PN10, PN16, PN25, and PN40 applications.

Furthermore, its compact design requires minimal space, and the corrosion-resistant epoxy coating protects against harsh environmental conditions. This makes it an ideal, versatile solution for water supply, wastewater treatment, and industrial cooling systems, guaranteeing long service life and operational safety.

This versatile double-flanged dismantling joint is a critical component for a wide range of pipeline applications, primarily designed to facilitate maintenance and accommodate system movement. Its robust construction, certified for pressures up to PN40, makes it ideal for use in water supply and distribution networks, both for potable and raw water. It is extensively used in wastewater and sewage treatment plants, where it allows for the easy removal of pumps, valves, and other equipment without requiring extensive pipe cutting.

The joint is equally essential in industrial cooling systems, firefighting pipelines, and industrial process lines. Its ability to absorb axial expansion and contraction, as well as minor misalignments, protects connected equipment from stress damage. The carbon steel flanges ensure a secure, high-integrity connection in these demanding environments. From municipal water works to chemical and manufacturing plants, this dismantling joint provides indispensable flexibility for system installation, repair, and long-term operational reliability.

The Double Flange Carbon Steel Ductile Iron Dismantling Joint is a precision-engineered pipeline component designed to provide unparalleled flexibility, strength, and reliability in pressurized fluid systems. Its primary function is to facilitate the installation, maintenance, and repair of pipeline equipment by allowing for controlled axial adjustment and easy disassembly of the line.

The core body of the joint is manufactured from high-grade ductile iron, a material renowned for its exceptional tensile strength, durability, and impact resistance, superior to standard gray cast iron. This ensures the joint can withstand significant internal pressures and external loads. Integral to the design are the flanges, which are fabricated from robust carbon steel. This material choice provides superior mechanical strength for bolting, ensuring a leak-tight, high-integrity connection to the adjacent pipeline flanges without risk of distortion.

A key feature is its ability to accommodate axial movement, including both compression and extension. This is vital for absorbing thermal expansion, settlement, and other dynamic forces within the pipeline, thereby protecting valuable assets like pumps and valves from harmful stress. The joint is equipped with high-performance elastomeric seals, typically EPDM or NBR, which guarantee a leak-proof seal across its entire pressure range.

To meet diverse system requirements, this dismantling joint is available in multiple pressure classes: PN10, PN16, PN25, and PN40, making it suitable for a wide spectrum of applications from municipal waterworks to demanding industrial processes. The compact design requires minimal installation space, and a standard corrosion-resistant epoxy coating is applied to ensure long-term performance even in challenging environments. It is the indispensable solution for ensuring operational continuity and ease of maintenance in any critical piping network.
