Customable Stainless Steel/Carbon Steel Metal Dismantling joint

Product Overview
The dismantling joint consists of a telescopic flanged body with a adjustable length section, sealing gaskets, and limiting rods. During installation, the joint can be extended or compressed within its designed stroke, allowing easy alignment between two fixed pipeline flanges. This eliminates the need for precise pipe cutting and reduces stress on adjacent equipment. When maintenance is required, the joint can be shortened to create enough clearance for removing valves or other components without dismantling the entire pipeline.
Material Options
The joint is available in two main material configurations. Stainless steel versions, typically made from grades such as 304, 316, or 316L, offer excellent resistance to corrosion, oxidation, and aggressive media, making them suitable for water treatment, chemical processing, food and beverage, and marine applications. Carbon steel versions, often with anti-corrosion coatings such as epoxy, fusion-bonded epoxy (FBE), or zinc-rich primer, provide high mechanical strength and cost efficiency for general water supply, drainage, HVAC, and industrial pipelines. Material selection can be customized according to the operating medium, temperature, pressure, and environmental conditions.
Customization Capabilities
As a customizable product, the dismantling joint can be tailored in multiple aspects. Nominal diameters can be produced to match specific pipeline sizes, from small-bore connections to large-diameter mains. Flange standards can be customized to DIN, ANSI, BS, JIS, or other international standards, with drilling patterns to suit existing mating flanges. The installation length, telescopic stroke, and limiting rod configuration can be adjusted to meet site conditions and maintenance requirements. Sealing materials such as EPDM, NBR, PTFE, or silicone can be selected based on the conveyed medium and temperature range. Surface treatment options include galvanizing, epoxy coating, and pickling passivation for stainless steel. Special requirements such as higher pressure ratings, vacuum service, or underground installation can also be accommodated.
Key Features
The product offers several practical advantages. Its adjustable length simplifies pipeline alignment and reduces installation time and labor cost. The telescopic design provides convenient maintenance access to valves and equipment, minimizing downtime. The combination of flanged ends and limiting rods ensures stable connection and prevents excessive extension or compression under pressure. Depending on the material and sealing selection, the joint can handle various media including water, wastewater, seawater, chemicals, and mildly corrosive fluids. It also helps absorb minor vibration, thermal expansion, and ground settlement, protecting the pipeline system from stress and damage.
Applications
This dismantling joint is widely used in water supply and drainage networks, wastewater treatment plants, pumping stations, desalination facilities, chemical plants, power plants, heating and cooling systems, and general industrial piping. It is particularly suitable for locations where valves, flow meters, or pumps need to be installed or serviced regularly, and where precise pipe lengths are difficult to achieve on site.
Quality and Testing
Each joint is manufactured under strict quality control. Welding, dimensional accuracy, and surface finish are inspected throughout production. Hydrostatic and airtightness tests are performed to verify sealing performance and pressure integrity. Material certificates and test reports can be provided upon request. Custom packaging and labeling are available for export and project delivery.
