Big Size SS Double Flange Push-Through Dismantling Joint for Pipeline Installation

Product Overview

The Large Size Double Flange Force Transfer Stainless Steel Metal Dismantling Joint is a specialized pipe fitting engineered to simplify the installation, maintenance, and removal of flanged equipment within large-scale piping systems. Designed for heavy-duty industrial applications, this joint provides robust axial adjustment capability while transmitting the end-load forces (blind plate thrust) from pumps and valves directly through the pipeline system, protecting critical equipment from stress damage .

Constructed from high-grade stainless steel, this dismantling joint offers superior corrosion resistance and durability, making it ideal for demanding environments including chemical processing, power generation, water treatment, and oil & gas installations .

Product Features

### Full Force Transfer Design
The double flange force transfer joint incorporates high-strength tie rods that securely connect both flanges, allowing the product to transmit axial thrust forces from the pipeline directly through the joint. This design protects pumps, valves, and other connected equipment from the damaging effects of blind plate thrust, particularly during pump startup .

### Longitudinal Adjustment Capability
The joint accommodates significant axial adjustment during installation (typically up to 100mm or more depending on size), providing flexibility to compensate for pipeline installation tolerances and simplifying the fitting of flanged components. Once the desired length is achieved, the tie rods lock the joint securely in position .

### Stainless Steel Construction
Manufactured from premium stainless steel materials (available in grades such as SS304, SS316, and alloy steel variants), the joint offers excellent resistance to corrosion, high temperatures, and aggressive media. This ensures long service life even in harsh industrial environments .

### Easy Installation and Maintenance
With a simplified design requiring only basic tools for installation, the dismantling joint allows for quick assembly and disassembly. This significantly reduces downtime during valve, 
pump, or meter maintenance, as the joint can be easily adjusted and removed without disrupting the entire pipeline system .

### Reliable Sealing Performance
The product features independent gasket compression studs, separate from the tie rods, ensuring long-term sealing performance that remains unaffected by external loads. High-quality EPDM or NBR sealing materials provide leak-proof operation across a wide temperature range .

### Compact, Space-Saving Design
Tie rods are contained within the flange bolt circle, eliminating the need for complex external anchoring systems and minimizing space requirements - particularly valuable in congested pump stations and confined chambers .
