DJ006 Dismantling Joint Carbon Steel
DJ006 is a carbon steel dismantling joint designed for pipeline systems requiring frequent disassembly and maintenance. It connects two pipe sections with a removable flange interface, allowing quick access to the line without cutting or welding. The joint is built for medium- and low-pressure applications across water, power, petrochemical, and heating systems, with a nominal diameter range from DN10 to DN2600 mm and pressure ratings from 0.05 to 4.0 MPa.

What This Model Gives You
- Enables rapid disassembly and reassembly of pipeline sections without cutting or welding
- Carbon steel construction provides strength and durability in medium- and low-pressure service
- Flanged connection allows integration into existing pipe systems with standard flange patterns
- Designed for repeated use in maintenance cycles without loss of sealing integrity
- Part of a valve and joint programme covering DN10 to DN2600 mm and 0.05 to 4.0 MPa
- Built under ISO 9001 and ISO 14001 certified manufacturing processes
Problems It Removes
- Traditional welded joints require cutting and re-welding, increasing downtime and risk
- Lack of access points in long pipelines makes inspection and repair impractical
- Frequent disassembly with bolted flanges alone leads to gasket misalignment and leaks
- Inconsistent joint types across a system complicate spare parts and maintenance planning
- Buyers need a single supplier for both valves and dismantling joints across the full DN10 to DN2600 range
Where It Is Installed
- Maintenance access in water supply and drainage pipelines where frequent inspection is required
- Service entry points in power plant auxiliary systems needing periodic cleaning or sensor replacement
- Petrochemical process lines where valves or instruments must be removed without disturbing the full run
- Heating system loops in district heating plants for access during seasonal maintenance
- Marine and metallurgical plant piping where joint access is needed for inspection or repair
Buyers It Suits
- Plant maintenance engineers managing systems with scheduled disassembly needs
- EPC contractors specifying access points in long pipeline runs for future service
- Water utility operators requiring quick access to buried or elevated pipe sections
- Industrial facility owners standardising on reusable joint solutions across multiple systems
- Valve and piping system integrators sourcing reliable dismantling joints in various diameters
How It Is Built
- Carbon steel body with flanged ends for connection to pipe flanges
- Removable flange interface allowing disassembly without pipe cutting
- Designed for use in medium- and low-pressure systems up to 4.0 MPa
- Nominal diameter range from DN10 to DN2600 mm
- Part of a joint programme certified to ISO 9001 and ISO 14001
- Suitable for water, steam, oil, and low-pressure gas services
Material Selection
- Body material is carbon steel; other material variants are confirmed on request
- Flange and bolt materials follow standard carbon steel or alloy grades based on pressure and service
- Material certificates are issued with the order when requested by the buyer
- All materials are selected based on the operating medium and temperature of the buyer's system
How It Is Made
- Carbon steel body cast and machined on in-house fine machining equipment
- Flange faces and bolt holes machined to standard patterns for compatibility
- Removable flange interface assembled with precision alignment
- Final assembly inspected for proper fit and alignment before testing
- Marked, wrapped and crated for container shipment from Tianjin
How It Is Checked
- Dimensional check of flange bolt pattern and face-to-face length before assembly
- Visual and dimensional inspection of machined surfaces and bolt holes
- Leak test performed on assembled joints at rated pressure
- 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 pipeline system
- Material variant selected based on medium and temperature requirements
- Optional marking and packaging for OEM or private label orders
- Mixed-diameter orders combined with other valves or joints in one container
How It Compares With the Alternatives
| Welded joint | A welded joint is permanent and requires cutting to disassemble; the dismantling joint allows repeated access without damage |
|---|---|
| Standard flanged joint | A standard flanged joint requires full disassembly of the line to remove; the dismantling joint allows access without removing the entire flange pair |
| Lug type butterfly valve | A lug valve is used for isolation; the dismantling joint is used for access and does not seal in the same way |
| Flanged coupling | A flanged coupling is for joining two pipes; the dismantling joint is designed specifically for disassembly and reassembly with a removable interface |
Installing and Operating This Valve
- Confirm the flange standard and bolt pattern on both pipe ends before ordering
- Align the joint flange with the pipe flanges before tightening the bolts
- Tighten bolts evenly in a cross pattern to ensure even seating and prevent leakage
- Use a gasket compatible with the medium and temperature of the system
- After disassembly, inspect the gasket and flange faces for damage before reassembly
- Do not use the dismantling joint as a pressure-containing closure during testing
