The function of the high-pressure self-sealing rotary compensator is to absorb the thermal displacement of the thermal pipeline by its rotation to play the role of thermal compensation. Therefore, whether the structure of the rotating cylinder is reasonable is of paramount importance. The overall advantages of high-pressure self-sealing rotary compensators are technically based on non-traditional principles that are completely different from other compensators. The combination of pressure and sealing force is combined into an outer circular sealing structure. Among the sealing materials, domestically advanced sealing materials are used, and theoretically, they can be used in a temperature difference of 1000 degrees, that is, in an environment of -200 ° C to 800 ° C. This product adopts the most scientific sealing structure. By reducing the double friction between the sealing surface and the sealing material, it can ensure that the material does not need to be installed within 10 years.

Product advantages

The high-pressure self-sealing rotary compensator consists of a rotating cylinder, a gland flange, a spring, a fastening flange, a guide slip ring, a packing, a retaining ring, a stop ring, an outer sleeve, a reducing tube, a screw and a nut. The fastening flange, the spring, the gland flange and the outer casing flange are tightened with bolts, and they are rotated radially with a guide slip ring to facilitate the rotation of the rotation cylinder. The 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 the fixed support. At the same time, the advanced technology of injectable filler device is added to this equipment, which makes the sealing performance of this equipment more stable and reliable. Even if there is a leak for a long time, maintenance can be performed without stopping the pressure and it is very convenient and fast. Especially for long-distance heat energy transmission, there are obvious economic and social benefits.

Features

1All parts of this product are specially designed according to the pipe material and design parameters provided by the customer, making the production more targeted. The components of the rotation compensator are made of integral forgings or pressed, and the product has higher pressure resistance and safety performance.

2 The sealing packing of the rotation compensator is processed through a special process, which adds eight materials such as alloy materials, carbon fiber, and antioxidants. The sealing performance is better, and the normal temperature can reach 550 ° C. If there are special requirements for temperature resistance Can be further improved.

3This seal packing has another advantage that the expansion coefficient is relatively high, the temperature on the steam pipeline is higher than the temperature during production, and the self-sealing effect can be achieved by the expansion of the seal packing.

4Specially added pressure-resistant seal assembly is specially added in the sealed cavity to increase the pressure resistance and sealing performance of the product.

Typical Case

Northeast Sichuan High Sulfur Natural Gas Project

The first column of the Luojiazhai Gas Field Purification Plant in the Northeast Sichuan High Sulfur Project (the Northeast Sichuan Project) produced qualified commercial gas and put it into operation on January 25, 2016, marking the development of a joint venture between PetroChina and the American Chevron Corporation. The Northeast project officially entered the production stage. This project is one of the largest onshore natural gas projects in China.
The Northeast Sichuan project spans Sichuan Province and Chongqing City and covers an area of over 800 square kilometers. China National Petroleum Corporation holds a 51% participation interest, and Unocal Tokai Co., Ltd. holds a 49% participation interest and acts as an operator.
The Luojiazhai gas field in northeastern Sichuan has a designed annual production capacity of 3 billion cubic meters. 5 old well repairs and 1 new well drilling operation have been completed, 3 well sites have been completed, with a production capacity of 9.8 million cubic meters per day, and a purification plant with a processing capacity of 3 billion cubic meters per year, 400,000 tons per year Production capacity: one sulfur plant and one gas gathering station; 29 kilometers of new gas gathering trunk line.
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 the fixed support. At the same time, the advanced technology of injectable filler device is added to this equipment, which makes the sealing performance of this equipment more stable and reliable. Even if there is a leak for a long time, maintenance can be performed without stopping the pressure and it is very convenient and fast. Especially for long-distance heat energy transmission, there are obvious economic and social benefits.
Following the commissioning of the first plant, the second and third plants will be put into operation one after another to achieve full production of the Luojiazhai gas field.
