3.Introduction to Single Sphere Rubber Expansion Joints for Changchun Mobile Production Center Project:
Single sphere rubber expansion joints can significantly reduce vibration and noise in pipeline systems. They can fundamentally solve various problems such as interface displacement, axial expansion, and eccentricity of various pipelines. Depending on the material, single sphere rubber joints can be made into various varieties such as acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, and heat-resistant, suitable for various media and environments. The material is polar rubber, with good sealing performance, light weight, easy installation and maintenance, and long service life. However, it should be avoided to contact with sharp metal instruments to prevent puncturing the sphere. For overhead use, elastic supports can be provided, and bolts should be tightened diagonally during installation. When the pipeline pressure is too high, extreme bolts should be used to connect the two end flanges together. The flange connection standard adopts GB4216.3-4216.5 standard, which can be specified separately. The working pressure of this product is divided into 0.6 MPa, 1 MPa, 1.6 MPa, and 2.5 MPa.
Performance characteristics: Single sphere rubber expansion joints are small in size, light in weight, good in elasticity, and easy to install and maintain. When installed, single sphere rubber expansion joints can produce lateral, axial, and angular displacement, without being limited by the misalignment of the pipeline and the non-parallelism of the flange. When working, single sphere rubber expansion joints can reduce structural transmission noise and have strong vibration absorption capacity.
