DJ002 Dismantling Joint Ductile Iron
DJ002 is a dismantling joint made from ductile iron, designed for temporary or permanent pipeline connections where disassembly and reassembly are required. It allows for quick access to pipeline sections without cutting or welding, and is suitable for water, heating, and low-pressure industrial services. The joint features a flanged body with a bolted clamp mechanism that secures the two pipe ends together during installation and removal.

What This Model Gives You
- Enables rapid disassembly and reassembly of pipeline sections without cutting or welding
- Ductile iron body provides good strength and impact resistance for medium- and low-pressure applications
- Flanged connection allows integration with standard pipe flanges across various systems
- Compact design fits into tight spaces where full valve access is not available
- Reusable joint body reduces material waste and long-term maintenance costs
- Part of a valve programme certified to ISO 9001 and ISO 14001
Problems It Removes
- Cutting and rewelding pipe sections during maintenance causes downtime and increases cost
- Lack of access points in existing pipelines makes inspection and repair difficult
- Standard flanged valves are too large or permanent for temporary access needs
- Reusable access joints are not available in the right size or pressure class
- Buyers need a single supplier for both valves and joint fittings across DN10 to DN2600
Where It Is Installed
- Maintenance access on water distribution lines in municipal or industrial plants
- Temporary bypass connections during pipeline repair or replacement
- Installation of new pipeline sections where existing flanges are already in place
- Access points in heating systems for inspection or sensor installation
- Service connections in petrochemical or pharmaceutical plants requiring periodic line access
Buyers It Suits
- Pipeline maintenance teams needing quick access points in water and heating systems
- Contractors installing or modifying industrial piping with limited space
- Facility engineers standardising on reusable joint solutions for service lines
- EPC firms sourcing reliable access joints for water and low-pressure projects
- Valve distributors stocking a range of joint types for industrial and municipal use
How It Is Built
- Ductile iron body with flanged ends for connection to pipe flanges
- Bolted clamp mechanism to secure the joint body around the pipe ends
- Designed for use in pipelines with nominal diameters from DN10 to DN2600
- Suitable for service pressures from 0.05 to 4.0 MPa
- Part of a product programme covering over 600 models and multiple valve families
- Built to allow repeated disassembly and reassembly without loss of integrity
Material Selection
- Body material is ductile iron, confirmed per order based on the buyer's line conditions
- All material combinations are selected against the medium and temperature requirements
- Material certificates are issued with the order upon request
How It Is Made
- Ductile iron castings inspected and machined on in-house fine machining equipment
- Flanges drilled and finished to match standard flange patterns
- Joint body assembled with clamp bolts and sealing components
- Each unit tested for tightness and mechanical integrity before packing
- Marked, wrapped and crated for container shipment from Tianjin
How It Is Checked
- Dimensional check of flange bolt holes and face-to-face length before assembly
- Seal integrity tested under pressure on the assembled joint
- Mechanical function tested by repeated clamping and unclamping
- Testing carried out on the 10 sets of imported inspection and testing equipment
- Records maintained under the ISO 9001 quality management system
Certificates Issued With This Valve
- ISO 9001 quality management system certification
- ISO 14001 environmental management system certification
Certification statements are limited to the management system certificates the factory actually holds. Product-level approvals for your market are confirmed before order.
What Can Be Changed
- Flange standard and drilling pattern matched to the buyer's existing pipework
- Material selection confirmed based on the line medium and temperature
- Private label marking and packaging available on OEM orders
- Mixed-diameter orders combined with other valves in one container
- Optional sealing gasket material selected for the service medium
How It Compares With the Alternatives
| Flanged pipe connection with welding | Welding requires skilled labor and cannot be undone; the dismantling joint allows repeated access without permanent changes |
|---|---|
| Standard flanged valve | A flanged valve is a permanent isolation point; the dismantling joint is designed for temporary or repeated access |
| Threaded joint | Threaded joints are limited to smaller diameters and cannot handle high pressure or repeated disassembly as reliably |
| Compression fitting | Compression fittings are not suitable for large-diameter or high-pressure applications; the dismantling joint supports DN10 to DN2600 |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe ends before ordering
- Ensure the pipe ends are clean and free of debris before inserting into the joint
- Position the joint body around the pipe ends and align the flanges properly
- Tighten the clamp bolts evenly in a cross pattern to avoid distortion
- Do not over-tighten bolts to prevent damage to the ductile iron body or gasket
- Inspect the joint and gasket before reassembly after each disassembly
