KYT-SUS304-DN80x65 concentric eccentric rubber expansion joint with stainless steel flange
Shanghai Songjiang Vibration Absorber Group Co., Ltd.’s official website introduces the KYT-SUS304-65×65 concentric eccentric rubber expansion joint with a stainless steel flange. This product is of KYT type, with the flange made from standard stainless steel SUS304 and a diameter of DN80x65mm. The term “concentric eccentric” indicates the presence of a pipe with varying diameters within a straight pipeline, requiring the use of rubber joint products to compensate for displacement and reduce vibration and noise.
Section One:
DN80x65 concentric eccentric rubber expansion joint flange material: Stainless Steel 304
Stainless Steel 304 is a commonly used material in stainless steel, with a density of 7.93 g/cm³. It is often referred to as 18/8 stainless steel, indicating it contains more than 18% chromium and 8% nickel. It has good high-temperature resistance up to 800°C, excellent processing properties, and high toughness. It is widely used in industrial and furniture decoration, as well as the food and medical industries. However, it’s important to note that food-grade 304 stainless steel has stricter composition requirements compared to standard 304 stainless steel. For example, internationally, 304 stainless steel typically contains 18%-20% chromium and 8%-10% nickel, while food-grade 304 stainless steel strictly contains 18% chromium and 8% nickel, with allowed variations within certain limits and restrictions on various heavy metal content. In other words, not all 304 stainless steel is food-grade 304 stainless steel. Common market labels include 06Cr19Ni10 (indicating Chinese standard production), 304 (usually indicating ASTM standard production), and SUS304 (indicating Japanese standard production). 304 is a general-purpose stainless steel used for making equipment and components that require good overall performance (corrosion resistance and formability). To maintain stainless steel’s inherent corrosion resistance, it must contain at least 18% chromium and 8% nickel. 304 stainless steel is a grade of stainless steel produced according to ASTM standards.
Section Two:
DN80x65 concentric eccentric rubber expansion joint flange material has various rubber material options:
Natural Rubber (for ordinary water, non-corrosive applications)
EPDM Rubber (for weak acids, alkalis, and lime slurry)
Nitrile Rubber (for hydraulic oil)
Fluoro Rubber (for temperatures below 140°C and strong acids and alkalis)
PTFE-lined Rubber (for temperatures below 150°C and strong acids and alkalis)
