HY-Dual-Flange Corrugated Compensator

Dual-flange stainless steel corrugated compensator is also known as expansion joint or telescopic joint customarily.

Subsidiary Classification:


Product Characteristics

Dual-flange stainless steel corrugated compensator is also known as expansion joint or telescopic joint customarily. It is composed of corrugated pipe (an elastic element) that constitutes its working body and other accessories such as end pipes, brackets, flanges and conduits, etc.lt has fine flexibility, corrosion, high temperature and pressure resistance. It can be connected with different pipes in any direction to compensate the temperature and absorb the vibration, reducing the noise, changing the direction of medium delivery, eliminating mechanical displacement between the pipelines or between the pipelines and the equipment,etc. Dual-flange stainless steel corrugated hose is applicable to the flexible joints of various pumps and valves with the displacement or vibration in particular. A variety of models are available to be customized based on our clients' specific requirements.


pipeline connections in the fields such as shipping, power plant, oil field, chemical industry, metallurgy, mines, large mechanical equipment, power system etc.


With anti-seismic, anti-impact and noise reduction elements:

The connector and repair device of this type changed the traditional rigid connection to the flexible one favorable to a status in which the pipes are of anti-impact & vibration and denoise.They themselves are resistant to the 350g acceleration impact within 0.02 seconds.By comparison with the flange way, the noise intensity is possible to be lowered by 80%, conducive to the utilization of the entire pipes system in a safe and normal way including the pump, the valve and the instruments, etc. prolonging service life.


Reduction in pipes weights:

The reduction in weight is attainable by about 75% compared to the one by flange way.


Saving in Pipes space:

Assembly and disassembly process do not require a full-phase construction by flange way, but only screwing the bold from one side, causing a saving of up to 50% both in pipes layout and construction space, being of great significance for the ships with space less available in configurating pipes system rationally.Flexible connection permits alternate angle 10 between the axis of two pipes, deviation angle 6 of single pipe,spacing of up to 5-35mm in pipes end.The loose tolerance limits avert the requirements of a high-precisionassembly,conducive to the promotion of advanced process structure measures such as the construction of the general section and the vibration isolation and noise reduction of the "Floating Raft" in the shipbuilding industry. There is no adverse effect on pipe connectors or repair device arising from the deviation in shipbuilding installment or the shifting made by the navigation.


High Cost Performance:

The construction expenses of the connectors and repair device are more economical than that of the flange. The individual cost is slightly higher than that of the general flange, but with long service life and high cost performance. In respect of the copper-nickel and stainless steel pipes, the individual cost is lower than or close to that of the medium diameter copper-nickel and stainless steel flanges.


Easy Maintenance:

When the pipes are under repair, even if there are the oil and water in them, no heating process should be done because of the disconnection of the welding, hence away from the danger of the fire or explosion. The rush repairs are applicable to the dual or open or foldable repair devices from outside all kinds of broken pipes in a bandaged way.


When our products are applied to the newly laid pipes project, the best economic result is achievable in terms of the manpower, material and financial resources.

lt sunnecessary to do plastic and smooth treatment in special on the end face and surface of the pipes at the construction site, only wipe off the soil for the installation provided there is no special deformation at the end of the pipes.

lt usually takes about 5 minutes to install a connector and only 10-20 minute to operate a repair device online.When working in a confined space in particular, it has more obvious advantages. One or two operators are enoughin general.

Our product is not influenced by the varied pipe materials and can be used effectively while the difference of pipes diameter and axis deflection angle are within specified scope.
