Introduction: Directly buried corrugated compensator is mainly used to absorb the axial displacement caused by thermal expansion or contraction along the axis direction of buried pipeline. It has the characteristics of resistance to soil pressure, self-directed, and can achieve the same life as the directly buried pipeline, without maintenance and replacement. This product is equipped with

Directly buried ripple Compensator It is mainly used to absorb the axial displacement caused by thermal expansion or contraction along the axis direction of directly buried pipeline. It has the characteristics of resistance to soil pressure, self-directed, and can achieve the same life as the directly buried pipeline, without maintenance and replacement. The product is designed as compensation limit structure, and the pipeline laying can not be equipped with guide bracket. It is used for pipeline transportation of corrosive medium or when there is corrosive medium in environment, anticorrosive coating can be applied on inner or outer wall of bellows. Any type of pipe can be flanged to the bellows and welded in the piping system. The diameter of the pipe can be from 75mm to 3000mm. The material can be carbon steel. Stainless steel and other alloy steel pipes can also be used. In the draft tube, the pressure drop is rare, because the medium flow is temporarily contracted into a neck, and then almost immediately returns to the beginning of the pipe. If the flow direction of the expansion joint is vertical upward, the guide tube can limit the liquid.
1. When the pressure drops to a low limit and the medium needs to flow smoothly and stably.
2. When the counter current and the flow direction of the medium change due to the eddy current of the medium in the expansion joint.
3. When it is necessary to protect the bellows from the influence of abrasives carried by media, such as catalyst or mud.
4. High temperature application, in order to make the bellows not affected by temperature. Because the draft tube is a protective barrier between the medium and the bellows.
5. It is used in air, steam and other gases.
6. When applied to water and other liquids.
It can be used in a variety of expansion rings. A common application is the inlet to the condenser of a steam waste turbine. These are usually not very likely to have round nozzles. The ferrule then provides a welded end face for those joints that are not very round. In a full vacuum system, the ferrule can also be used as a reinforcing element.
Protective cover: the protective cover can be provided in two ways: fixed or movable. The fixed form of the protective cover can be applied when the condition of high speed flow of external steam such as condenser or heater connection exists. The movable protective cover is the standard part of our company, which allows periodic inspection service. The protective cover shall be used to prevent installation and operation or when welding is about to be carried out. If an expansion joint is to be externally insulated or insulated, consider using a protective cover. For any kind of expansion joint, our company recommends the use of protective cover, because the increased cost is a more economical insurance measure compared with replacing the whole expansion joint.
Pull rod: the pull rod is a device often in the form of rod or rod. It is installed and assembled on the expansion joint and designed to absorb pressure load and other external forces such as rated load. When the pull rod is used on single or universal expansion joint, the ability to absorb axial displacement is lost. The limiting rod is used to protect the bellows when the displacement is beyond the design range due to factory failure or fixed failure. During normal operation, the limit bar cannot be used to withstand pressure and thrust. The bellows are designed to prevent excessive compression and failure due to excessive pressure. The limit bar does not work during normal operation.
Control rod: the control rod is a device connected to the expansion joint. Its main function is to disperse the displacement between the two bellows of the universal expansion joint. The control rod can not restrain the pressure and thrust of bellows.
Reinforcing ring: when the design pressure, diameter and temperature of the expansion joint increase, the corrugated part needs to be strengthened to control the circumferential stress of the thin-walled bellows. Depending on the design of these components, there are various types of reinforcement rings called reinforcement rings.
