Performance Features
Small size, light weight, good elasticity, easy installation and maintenance.
. It can produce lateral, axial and angular displacement during installation, and is not restricted by pipes that are not through the center and flanges that are not parallel.
. It can reduce structural transmission noise during operation and has strong vibration absorption ability.
Scope of use
Due to its good comprehensive performance, the flexible rubber elbow is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, and electric power and other basic projects.
Instructions for use
When using rubber elbows for high-rise water supply, the pipeline must have fixed supports or fixed brackets, otherwise the product should be equipped with an anti-pull-off device. The force of the fixed support or bracket must be greater than the axial force, otherwise an anti-pull-off device should also be installed.
Applicable media
Depending on the material, it can be made into various varieties such as acid resistance, alkali resistance, corrosion resistance, oil resistance, heat resistance, etc., adapting to a variety of media and environments
Installation method
Glue bending When installing the head, it is strictly prohibited to install beyond the displacement limit.
The bolts should be installed symmetrically and tightened gradually to prevent local leakage.
For the above working pressure, the mounting bolts must have elastic pressure pads to prevent the bolts from loosening during work.
During direct installation, both ends of the joint pipe should be supported by vertical force, and anti-pull-off devices can be used to prevent the work from being pulled off under pressure.
The installation part of the rubber elbow should be away from heat sources and oxygen areas. It is forbidden to expose to strong radiation and use media that does not meet the requirements of this product.
It is strictly forbidden to use sharp instruments to scratch the surface and sealing surface of the rubber elbow during transportation, loading and unloading.

Rubber joints require a combination of scientific and technological progress and innovation
Under the guidance of the Scientific Outlook on Development, rubber joint enterprises will further deepen reforms, work hard to improve scientific and technological progress and innovation, adhere to the new industrialization path, and combine speed and efficiency The rubber joint industry will surely develop soundly and rapidly as the growth model gradually shifts to a quality- and horizontal-efficiency-oriented track. Today, when informatization drives the development of industrialization, we must not only see the achievements, but also pay attention to the backwardness. We must seize the opportunity and take measures to improve the level of rubber joints as soon as possible and integrate into the international community as the trend of economic globalization is accelerating. In order to promote the rapid development of China's rubber joint industry, two aspects should be paid attention to: First, relevant government policies play a very important role in promoting the development of the rubber joint industry. From an international perspective, the rubber joint industries in various countries have received strong support from the government in the early stages of development. Judging from the actual situation in China, the tariffs on imported precision rubber joint production equipment that cannot be produced domestically should be reduced, and the country's preferential policies for some professional rubber joint factories should be implemented. The development and progress of the industry can be accelerated through policy guidance.
Second, with the development of the market, the diversified molding methods of rubber joints will inevitably continue to develop in the future, so the requirements for rubber joints are becoming higher and higher. In order to meet the needs of the market, future rubber joint molds will develop rapidly in terms of variety, structure, performance and processing, and this development must keep pace with the times.
