Product advantages

Compared with the traditional expansion device, the product has the advantages of light weight, excellent performance, novel structure, simple and convenient installation, good sealing effect, and the sealing strength can be adjusted freely according to the needs.

1. The product is very convenient to use, whether it is a new installation of the pipeline or the maintenance of the original pipeline, there is no need to field welding, no need to punch, only need to connect according to the installation method, saving manpower.

2. The product is equipped with flange rubber gasket and bell mouth rubber seal ring, which can realize quick connection at construction site.

3. The rubber flexible seal is used between the socket and the pipe, and the sealing strength can be adjusted to make the seal more safe and reliable.

4. The product expansion compensation is large. Especially for the plastic pipe with large thermal expansion coefficient and the pipeline with large stress, it is suitable to use this product.

Product features

The bearing plate expansion device can be used for water supply and drainage engineering, and for thermal engineering, the general temperature is 250 ℃, and the pressure is 1.6 MPa. At the same time, we can also produce series of products with special parameters according to the needs of users, so as to meet the requirements of gas, petroleum, chemical industry, hydropower and other fields. According to the current ~ standard, the flange connection size can be added with anti pulling limit bolts according to the user's requirements. Compared with the traditional expansion device, the product has the advantages of light weight, excellent performance, novel structure, simple and convenient installation, good sealing effect, and the sealing strength can be adjusted freely according to the needs.

Connect one end of the flange of the product with the flange on the pipe or the flange of the valve fitting, and insert the pipe into the socket at the other end. The insertion length should be slightly less than the total length of the product. The insertion length mark can be drawn at the insertion end of the pipe in advance for accurate grasp.
1. Before installation, check whether the adjusting bolt is in a very loose and strong state, and the rubber seal ring in the bell mouth should not be squeezed.
2. When inserting the pipe, apply soapy water on the pipe in advance to reduce friction and facilitate insertion.
3. After the pipe is inserted, the adjusting bolt should be tightened gradually so that the rubber sealing ring in the socket can be tightly combined with the pipe.
4. If the product is used at the end of the pipeline (i.e. the end of the pipeline), the end buttress should be considered to offset the thrust generated by the medium in the pipeline

The socket expansion joint provides safety guarantee for Golmud refinery pipeline project

Up to now, the diesel oil quality upgrading and transformation project of Geermu refinery in Qinghai Oilfield has been running smoothly for nearly two months after the completion acceptance. This project is undertaken by East China design branch of engineering and construction company, including 800000 T / a hydrotreating unit transformation, 150000 T / a diesel hydrofining transformation and its supporting facilities. After the implementation of the project, the diesel products of Geermu refinery can be directly upgraded from national III standard to national V standard, and the diesel output is increased from 50.46% to 88.90% - 97.20%. At the same time, the energy consumption of the unit is greatly reduced by optimizing and adjusting the process flow.
This time, Shanghai Luoying, as the main extender supplier for the pipeline project upgrading of Golmud refinery, has signed a project order of more than 300000 yuan with Golmud refinery. We will surely be down-to-earth and operate in good faith to create another brilliant future. Luoying bearing plate expansion device can provide great convenience for the installation and replacement of water tower, pump room, water meter and valve in town, and can effectively solve the problem of expansion and contraction caused by temperature difference in long-distance pipeline, instead of U-tube. One end of the product is a flange and the other end is a socket. It can be connected with ductile iron pipe without welding seam or flange. Compared with the traditional expansion device, the product has the advantages of light weight, excellent performance, novel structure, simple and convenient installation and good sealing effect.
Golmud refinery is the only one million tons refinery in Qinghai Tibet Province, which is responsible for supplying military and civilian refined oil to Qinghai and Tibet. The smooth implementation of the quality upgrading and reconstruction project of Geermu oil refinery is of great significance to the supply guarantee of refined oil in Qinghai and Tibet, the economic growth of western region and the long-term development of Golmud refinery.
