Three-sphere flexible winding rubber joint with limit

- Product Introduction

Flexible rubber joints are mainly used for flexible connection of metal pipes for conveying liquids, gases, solids and other materials. They can compensate displacement, isolate vibration and reduce noise. They are a novel rubber vibration reduction product. This product is at the leading level in China because the main skeleton material is the first to use polyester cord. It has won the quality product certificates issued by the state, province and city for many times, and has been listed as a designated production unit by the Ministry of Chemical Industry, Sinopec, the Ministry of Metallurgy and the Ministry of Construction. The products have been listed as the preferred products by more than 30 large and medium-sized design institutes across the country.

- Product Features

This product mainly utilizes the unique properties of rubber, such as high elasticity, high air tightness, medium resistance, weather resistance and radiation resistance. It is made of high-strength, hot and cold stable polyester cord, which is cross-linked by high-pressure and high-temperature molding. It has high internal density, can withstand high pressure, and has excellent elastic deformation effect. The product structure is designed with a high arc section and a long curve, and has a large multi-directional displacement function. It is particularly suitable for places with complex geological conditions, large settlement amplitude and frequent hot and cold changes during pipeline operation, which can easily cause pipeline damage. The elastic sliding transfer and heat dissipation function of the deformation mechanical force of rubber can effectively eliminate the displacement physical damage of pumps, valves and pipelines. Because rubber is a poor conductive material, it is also an ideal environmentally friendly product that reduces vibration and noise transmission. The inner wall of the product is designed to be smooth. After actual testing, it has no effect on the flow rate and flow of the medium, and it will never induce, and basically can be exempted from maintenance during the effective operation period.

- Product application range

Because the flexible rubber joint has good comprehensive performance, it is mainly used for the lifting and transportation of raw water and sewage, water supply and cooling circulating water of thermal power plants, condensate water of the metallurgical industry, pipeline transportation of chemical substances in the chemical industry, cooling, dilution and flexible connection between long and short distance pipelines in other industries. Because rubber has high wear resistance, it is also suitable for low-temperature transportation of granular, powdery and gas in all industries. In addition, in order to ensure the quality of the project, the design department and the user unit are particularly reminded that if you design and install this product near the outlet of the water pump or the corner of the pipeline, please indicate the addition of an anti-pull-off limit device. If your pipeline needs to be buried underground, please use our company's newly patented product, the geographic protection device. In short, as long as there are certain hidden dangers in your use conditions, please indicate the use conditions when ordering, and we will provide you with a satisfactory answer in time.

- Product Outstanding Features

Our company has been producing flexible rubber joints since the early 1990s. After more than ten years of practice and many technical improvements, we have also referred to the technical data of similar products in the United States, Japan and other countries, and took the essence of them. In early 2000, we developed a new product-end face fully sealed flexible rubber joint. Compared with the old product, it has the following characteristics:

1. The protruding surface of the spherical end of the flexible rubber joint is changed from a square groove to a full end face seal, which increases the contact surface of the rubber joint and improves the sealing performance by 60%; the sealing surface is 100% in contact with the matching flange, and the connecting bolts act directly on the sealing surface, making full use of the elastic compression deformation seal of the rubber. It prevents the rubber joint from pulling off, improves the pressure resistance of the joint, and there is no leakage.

2. The sphere of the flexible rubber joint is changed from a low arc sphere to a high arc arch, which increases the displacement and compensation by 50%-60% compared with similar products, making the performance more reliable and users can use it with confidence.

3. The rubber joint has various installation forms and is not affected by the climate environment. It can be installed indoors, outdoors or underground.

4. The rubber joint has the characteristics of high compressive strength, convenient loading and unloading, good sealing performance, corrosion resistance, displacement compensation, and balance deviation.

5. The flexible rubber joint is installed on the steel pipe connected to the structure. Its function is to absorb the system deformation caused by temperature changes, structures, and ground settlement to avoid tearing of structures and deformation of pipelines. It is also very important for the safe operation of pipelines.
