3.Introduction to Rubber Expansion Joints at Zhaoxian Qingyuan Sewage Treatment Plant Project:
Product Features:
（1）Single-ball rubber joints can significantly reduce vibration and noise in pipeline systems, fundamentally solving various problems such as interface displacement, axial expansion, and eccentricity of pipelines.
（2）The rubber joints for sewage treatment plants are made of EPDM rubber, which has the characteristics of acid resistance, alkali resistance, corrosion resistance, and heat resistance, specifically suitable for the media and environment of sewage treatment plants.
（3）The material is polar rubber, with good sealing performance, light weight, convenient installation and maintenance, and long service life. However, it should avoid contact with sharp metal instruments to prevent puncturing the ball.
（4）When used overhead, elastic supports can be provided. During installation, bolts should be tightened diagonally.
（5）When the pipeline pressure is too high, limit bolts should be used to connect the two end flanges.
（6）The flange connection standard adopts the GB/T9119-2000 standard; the working pressure of this product is: 0.6 MPa to 1.6 MPa.
