Single Sphere Flexible Wound Rubber Joint

Flexible rubber joints are mainly used for the flexible connection of metal pipelines for transporting liquids, gases, solids and other materials, which can compensate for displacement, vibration isolation and noise reduction, and are a novel rubber vibration reduction products. The product is at the leading level because the main skeleton material is the first to use polyester cord in China. It has been awarded the high-quality product certificate 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, China Petrochemical Corporation, the Ministry of Metallurgy and the Ministry of Construction, and the products have been listed as the preferred products by more than 30 large and medium-sized design institutes across the country.

- Product features

The product mainly uses the unique properties of rubber, such as high elasticity, high air tightness, medium resistance, weather resistance and radiation resistance, etc., and is made of polyester cord with high strength, strong cold and heat stability after being composed with it, and cross-linked by high pressure and high temperature molding. The internal density is high, it can withstand high pressure, and the elastic deformation effect is excellent. The product structure design section has high arc and long curve, and has a large multi-directional displacement function. It is especially suitable for places with complex geological conditions, large settlement and frequent cold and heat changes in pipeline operation, which are easy to cause pipeline damage. The elastic sliding transfer of rubber and the heat transfer and escape function of deformation mechanical force are used to effectively eliminate the displacement and physical damage of pumps, valves and pipelines. Because rubber is a poor conductive material, it is an ideal environmental protection product to reduce vibration and noise transmission. The product is designed to have a smooth inner wall, and has no effect on the flow rate and flow rate of the medium after actual testing, and will never be tempted, which can basically eliminate maintenance during the effective operation period.

- Scope of application

Due to the good comprehensive performance of flexible rubber joints, they are mainly used for the lifting and transportation of raw water and sewage, the feed water and cooling circulating water of thermal power plants, the condensate of the metallurgical industry, the pipeline transportation of chemical substances in the chemical industry, the cooling and dilution of the petrochemical industry and the flexible connection between long and short distance pipelines in other industries. Because rubber has high wear resistance, it is also suitable for low-temperature conveying of granular, powdery and vapor in all industries. In addition, in order to ensure the quality of the project, the design department and the user unit are reminded that if you design and install the product at the near end of the outlet of the pump or the corner of the pipeline, please indicate the addition of an anti-pull-off limit device. If your pipes need to be buried underground, please use our new patented product geo-protection device. In short, as long as there are certain hidden dangers in your conditions of use, please indicate the conditions of use when ordering, and we will provide you with a satisfactory reply in a timely manner.

- Outstanding features of the product

Our company began to produce flexible rubber joints since the early 90s, after more than ten years of practice, after many technical improvements, while referring to the technical data of similar products in United States, Japan and other countries, taking its essence, in early 2000 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 ball of the flexible rubber joint is changed from a square groove to a full seal of the end side, which increases the contact surface of the rubber joint and improves the sealing performance by 60%; The sealing surface is in full contact with the matching flange 100%, and the connecting bolts act directly on the sealing surface, making full use of the elastic compression deformation sealing of the rubber. It prevents the pull-off of the rubber joint, improves the compressive strength of the joint, and has no leakage.

2. The ball of the flexible rubber joint is changed from a low-arc spherical type to a high-arc arch, so that the displacement and compensation amount are increased by 50%-60% compared with similar products, and the performance is more reliable, and the user can use it with confidence.

3. The rubber joints are installed in various forms, which are not affected by the climate and environment, and can be installed indoor, outdoor or buried.

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

5. The flexible rubber joint is located on the steel pipe connected to the structure, and its function is to absorb the system deformation caused by temperature changes, structures and ground settlement, so as to avoid tearing of the structure and deformation of the pipeline, which is also very important for the safe operation of the pipeline.
