The function of high pressure self sealing rotary compensator is to absorb the thermal displacement of thermal pipeline by its rotation, so as to play the role of thermal compensation. Therefore, whether the structure of the rotating cylinder is reasonable or not is very important. The overall advantages of high-pressure self sealing rotary compensator adopt the unconventional principle which is completely different from other compensators. The combination of pressure and sealing force forms a cylindrical sealing structure. One of the sealing materials, the use of domestic advanced sealing materials, theoretically can be used in the entire 1000 degrees temperature difference, that is - 200 ℃ ~ 800 ℃ environment. This product adopts a very scientific sealing structure. By reducing the friction between the sealing surface and the sealing material, it can ensure that the material does not need to be installed in 10 years.

Product advantages

The high pressure self sealing rotary compensator is composed of rotating cylinder, gland flange, spring, fastening flange, guide slip ring, packing, retaining ring, limiting ring, outer sleeve, reducing pipe, screw and nut. The fastening flange, spring, gland flange and sleeve flange are tightened with bolts, and the guide slip ring is used for radial rotation between them and the rotating cylinder, so as to facilitate the rotation of the rotary cylinder. High pressure self sealing rotary compensator has the advantages of large compensation capacity, small fluid resistance and deformation stress, no blind plate force and small force on fixed support. At the same time, the advanced technology of injection packing device is added to the equipment, which makes the sealing performance of the equipment more stable and reliable. Even if leakage occurs during long-term operation, it can be maintained without stopping gas and decompression, and it is very convenient and fast. Especially for long-distance heat transfer, it has obvious economic and social benefits.

Product features

All parts of this product are specially designed according to the pipe material and design parameters provided by customers, which makes the production more targeted. The components of the rotary compensator are all made of integral forging or pressing, so the pressure resistance and safety performance of the products are higher.

2. The sealing packing of rotary compensator is treated by special technology, in which eight kinds of materials such as alloy material, carbon fiber and antioxidant are added. The sealing and compressive properties are better, and the normal temperature can reach 550 ℃. If there are special requirements, the temperature resistance can be further improved.

The sealing packing has another advantage: the expansion coefficient is relatively high, the temperature on the steam pipe is higher than that in production, and the self sealing effect can be realized by the expansion of the sealing packing.

4. The special pressure sealing assembly is added in the sealing cavity, which increases the compression resistance and sealing performance of the product.

Northeast Sichuan high sulfur natural gas project

Luojiazhai gas field purification plant and train assembly plant of Northeast Sichuan high sulfur project (Chuandongbei project) produced qualified commercial gas and put into operation on January 25, 2016, marking that the Northeast Sichuan project jointly developed by PetroChina and Chevron has officially entered the production stage. The project is one of the largest cooperative natural gas development projects in China.
The Northeast Sichuan project is located across Sichuan Province and Chongqing City, covering an area of more than 800 square kilometers. CNPC holds 51% of the participating interests, while Unocal East China Sea Co., Ltd. holds 49% of the participating interests and acts as the operator.
The design annual production capacity of Luojiazhai gas field in Northeast Sichuan is 3 billion cubic meters. Five old wells and one new well have been completed. Three well sites have been built with a wellhead production capacity of 9.8 million cubic meters per day. A purification plant with a capacity of 3 billion cubic meters per year, a sulfur plant with a production capacity of 400000 tons per year and a gas gathering station have been built. The new gas gathering trunk line is 29000 meters.
The high pressure self sealing rotary compensator produced by Shanghai Luoying has the advantages of large compensation capacity, small fluid resistance and deformation stress, no blind plate force and small force on fixed support. At the same time, the advanced technology of injection packing device is added to the equipment, which makes the sealing performance of the equipment more stable and reliable. Even if leakage occurs during long-term operation, it can be maintained without stopping gas and decompression, and it is very convenient and fast. Especially for long-distance heat transfer, it has obvious economic and social benefits.
After the first train of units is put into operation, the second and third trains will be put into operation one after another, so as to achieve the full production capacity of Luojiazhai gas field.
