Expansion Joint  

Daming Corrugated Pipe Co,.Ltd is one of the leading manufacturers of expansion joints and metallic bellows.

With over 15 years of experience in the design and manufacture of bellows expansion joint combined with our state of the art on-site facilities enables us to offer a wide range of bellows suitable for any application and design requirements.

This pipe expansion joint is simply a bellows element with end connections. Regardless of accessories, such as liners and covers, it will deflect in any direction or plane that the bellows will. It is the least expensive type, but requires that the piping be controlled as to the direction of the movements required of the unit. The pipe expansion joint should not be expected to control the movement of the pipe. If the piping analysis shows that the pipe expansion joint must accept axial compression, then the piping must be guided and constrained so that only that movement will occur.

This expansion joint will not resist any deflections with any force other than the resistance of the bellows, which is a function of the spring rate times the deflection amount. It is incapable of resisting the pressure thrust along its axis, which is the product of the pressure times the effective, or cross sectional, area of the bellows. Large diameter units, even with low pressures, can generate very large axial pressure thrust forces, which must be reacted by main and directional anchors. Otherwise the expansion joint will extend with disastrous results.

 

Features
1.Shock absorption
2.Easy installment and keep up
3.Resistant to medium and temperature, pressure
4.This product can greatly reduce vibration and noise, pipeline system but can not solve all kinds of pipe interface displacement, degree of axial stretching problems.
5.The material can be made according to different acid, alkali, corrosion, oil heat and other kinds of species to adapt to various of media and the environment.
6.Material is a polar rubber, sealing, light weight, easy installation and maintenance, long life, but to avoid contact with sharp metal instruments, so as not to puncture the sphere.
7.Without supporting bracket should use flexible stent, installation bolt tightened to use the diagonal method
8.Such as the pipeline pressure is too high, the application of limit bolts to both ends of the flange together.
9.Flange connection standard adapt GB standard as to other standards, can be explain. Level of the product working pressure 0.1-6.0Mpa.

FAQ 

Who Are DAMING ?

DAMING  is a family owned manufacturing company specialising in the correct design, manufacture and supply of stainless steel flexible hoses, bellows ,expansion joints and pipe fabrications for 10 more years in China.

 

Can You Manufacture Metallic Bellow Expansion Joint To My Requirements?

Yes, we can tailor our metallic bellow expansion joint to your requirements, just get in touch for more information.

 

What is axial deflection?

Axial deflection refers to movement of the expansion joint in regards to changes in the dimensional length of the 

bellows parallel to the center line of the expansion joint.

What is the Role of Limit Rods?
There are always several limit rods on limit expansion joints or bellows. What is the role played by limit rods? Well, limit rods may be used in an expansion joint design to limit the axial compression or expansion. They allow the expansion joint to move over a range according to where the nut stops are placed along the rods. Limit rods are used to prevent bellows over-extension while restraining the full pressure thrust of the system.

 

Ways to Prevent and Minimize Expansion Joint Failure
There are various actions that can be taken to prevent and minimize expansion joint failure. During installation, prevent any damage to the bellows by carefully following the instructions furnished by the manufacturer. 
After installation, carefully inspect the entire piping system to see if any damage occurred during installation, if the expansion joint is in the proper location, and if the expansion joint flow direction and positioning is correct.
Also, periodically inspect the expansion joint throughout the operating life of the system in order to check for external corrosion, loosening of threaded fasteners and deterioration of anchors, guides, and other hardware.
