View SpecificationBuyers This Category Suits
- Maintenance teams in water treatment plants needing to isolate sections for cleaning or repair
- Power plant engineers performing routine inspection on boiler feedwater or condensate lines
- Petrochemical and chemical plant operators managing high-pressure process lines with frequent maintenance cycles
- Marine engineers servicing shipboard piping systems where space and safety are critical
- Pharmaceutical and metallurgical plant managers requiring clean, reusable joints for hygiene and durability
What It Fixes on the Line
- Pipeline systems require frequent access for inspection or component replacement but existing joints do not allow quick disassembly
- Cutting or welding to disconnect pipes causes downtime, heat damage and potential safety risks
- Non-standard or custom fittings increase lead time and cost for temporary disconnection solutions
- Multiple brands or materials in one system complicate spare parts inventory and maintenance planning
- Large-diameter pipelines need robust, reusable joints that maintain alignment and seal integrity after repeated assembly

Dismantling Joints FAQ
What materials are available for dismantling joints?
Carbon steel and ductile iron models are available. The exact material for a specific model is confirmed on request.
What sizes and pressures are supported?
The series covers nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. The exact size and pressure rating per model are confirmed on quotation.
Can the joints be reused after disassembly?
Yes. Dismantling joints are designed for repeated assembly and disassembly while maintaining seal integrity and alignment.
Are the joints compatible with existing pipeline materials?
Yes. Available in carbon steel and ductile iron to match common pipeline materials used in water, power, chemical and marine systems.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.
Can I order mixed models in one shipment?
Yes. Dismantling joints can be combined with other valve types and fittings in a single container for project delivery.
Do you supply joints with flanges or threaded ends?
The standard configuration is flanged ends. Special end types are confirmed on request.
