Product Description

Product Description

 
 

      Steel flexible joint is also called clamp, open expansion joint, steel flexible pipe joint. Steel flexible joint is a kind of pipe connection, reliable performance, easy to install products. At low pressure, by the elastic deformation of the sealing ring, to achieve the purpose of sealing; When the pressure increases, the medium acts on the sealing ring to play the role of self-sealing, and there is a gap between the pipe ends to compensate for the displacement and deflection of the pipe caused by thermal expansion and cold contraction.


The working temperature of the clamp joint is generally -30ºC-+130ºC. The medium property is weak acid, weak alkali and lubricating oil range can be applied. If beyond the above range can also provide our company with the nature of the medium parameters or optional parameters or optional specified rubber ring material. In addition to the connection function, the joint can also provide compensation, withstand axial force, provide Angle, reduce vibration wave, adapt to the change of foundation.


The advantages of clamp joint:


1 Clamp joint has good continuity, will not produce distortion, easy to achieve the ideal laying state.
2 Clamp pipe joint in a free state, do not bear the weight of the pipe, not subjected to external shear, especially DN200 pipe diameter, more must consider the weight of the pipe.
3. It is easy to keep the coaxial position when installing the clamp joint to ensure the uneven distribution of the radial clearance between the inner diameter of the pipe clamp and the outer diameter of the pipe. The rubber ring will be deformed under high pressure due to the large local clearance, which will affect the sealing effect and even destroy the rubber ring.
4. It is suitable for the application in the subsidence zone, which can reduce the Angle between the pipe segments caused by the subsidence of the support pier.
5 is conducive to pipeline maintenance. Turn the pipe, save labor and effort when changing the pipe.

Installation Instructions

 

1. Prepare groove pipe sections, fittings and accessories that meet the requirements.

2. Check whether the rubber sealing ring is damaged and put it on the end of a steel pipe.
3. There should be a certain gap between the end and both ends of the steel pipe close to the end and both ends of the pipe which has been         covered with rubber sealing ring. The clearance shall meet the standard requirements.
4.  Put the rubber seal ring on the end of another steel pipe, make the rubber seal ring in the middle of the interface, and apply lubricant on the same side.
5. Check the axis of the pipe.
6. Install upper and lower clamps on the outer side of rubber seal-ing ring at the interface position, and clip the collar convex edge into the groove.
7. Press the upper and lower clamp ears with hand force, tighten the collar of the clamp with a wooden hammer, and tighten the upper and lower clamps tightly.
8. At the clamp screw hole position, put on the studs and tighten the nuts evenly to prevent the rubber sealing ring from wrin-kling.
9. check  and  comfirm  that  the  collar  convex  edge  is  clamped  into  the  groove.
