Product Description

RSF VALVE is a leading manufactuer of ductile iron pipe fittings. We have more than 15 years experience in producing ductile iron dismantling joint, flange adapter, flexible coupling, etc.

RSF’s ductile iron dismantling joint is used to connect pipes or valves with flanges at both ends. Our ductile iron dismantling joint has the characteristics of adjustable length to facilitate field adjustment during on site installation.

There is 50mm telescopic adjustment between double flange of our ductile iron dismantling joint. Adjust and lock the required adjustment through the connect bolt. Our dismantling joint can be quickly dismantled and is very easy to service valves, pumps or instrument. It simplifies the time during the maintenance and alteration in the future pipeline and reduce the downtime in the entire pipeline project. Using only one wrench torque wrench to tighter high strength steel or Stainless Steel bolted connections is one of the most important features of this range products. In view of the above characteristics, the customer’s demand for product inventory has been reduced.


The nominal diameter of RSFductile iron dismantling joint ranges is from DN40 to DN2200, and the drilled flange and nominal pressure is PN10 \ PN16 \ PN25 \ PN40 \ Class125 \ Class150. The customer has some special requirements for our dismantling joint that can also be designed manufactured to meet customer requirements. The simplicity and versatility of RSF's ductile iron dismantling joint make them suitable for many applications, including pumping stations, water treatment plants, sewage treatment plants, plant rooms, instrument rooms, power generation equipment, gas stations and so on. Dismantling joint is well install and remove for isolation valve, control valve, check valve, check valve flow measurement valve, pump, pressure relief valve, flange pipe etc. Our ductile iron dismantling joint design and manufacturing in accordance with ISO 9001: 2015 system, anti-corrosion materials through the most stringent WRAS certification, can be used for drinking water. Our dismantling joint coated with WRAS water certified epoxy powder coating, we provide excellent protection from transportation, storage, on-site and corrosion damage. The zinc plated nut and bolt coating is used to provide long-term rust protection.


Step 1.Check the package and appearance of dismantling joint to ensure that it has not been damaged during the transport and that no parts have been lost.

Step 2. Check the flange to which dismantling joint fits. Make sure it matches the bore of the product flange. Nominal pressure must be consistent.

Step 3. Remove the pull rod bolts from dismantling joint loosen the nut and take the pull rod bolts so that the pipe moves freely in the body of flange connection.

Step 4. Move dismantling joint between the flanges to be assembled. There is O-Ring Gasket between the flange and the flange for sealing. Use flange bolts to secure the flange end of dismantling joint fix the flange end which need attach. Screw the bolt tightly.

Step 5. Connect the flange spigot to the opposite mating flange. Flange type O gaskets are added between the flange faces and bolted together with flange bolts.

Step6. After bolts connect flange, self sealing of dismantling joint put into the program. At first in the middle of Rubber seals with lubricant to ensure that the intermediate flange and intermediate sealing ring slide to the location, and check the small self connection bolt gasket and nut.

Step 7. Insert the pull rod bolts. (Note: if no rod bolts, the product is not limited. Each rod has 4 nuts at assembly. When the pull rod is inserted, the bolt is connected with the nut. The pull rod bolt lever must be through the flanges at both ends of dismantling joint. Make sure that the length of the connector is equal to meet the requirements of the flanges at both ends. The other nut tightening on the joint after tightening rod nut so as to complete the installation.

Step 8.Evenly press the bolt on the press in the alternating direction of the screw until it reaches the recommended torque. Wait ten minutes, then torque.


1. The bolt is not tight to meet the requirement torque.

2. A small piece of rock or debris between seals or gaskets.

3. Dirt on bolts or nuts causes problems with nut fastening.

4. The short distance is inserted by the spigot pipe.

5. Incorrect mating flange.

Warmly welcome to choose RSF VALVE's dutile iron dismantling joint. If you have any inquiry of our ductile iron pipe fittings such as dismantling joint, flange adapter, universal coupling, universal flange adapter, flexible coupling, please don't hesitate to contact with us!
