Introduction
A rubber flange seal is a gasket made of rubber, usually used at the joints of pipes or equipment to seal.
Flange seals a pipe joint with high elasticity, high air tightness, medium resistance, and weather resistance.
It consists of inner and outer rubber layers, cord layers, and wire rings to form a tubular seal. After vulcanization and molding, it is combined with a metal flange or parallel joint loose sleeve.
When selecting a rubber flange seal, you need to consider its operating temperature, pressure, medium, and other conditions, as well as the standards and specifications of the flange connection. Common standards include the PN series (European system), Class series (American system), and GB series (Chinese system), etc. According to different systems and standards, the models, sizes, and specifications of rubber seals will also vary.
Certification Standards
1. Comply with relevant drawings and technical documents: Rubber seals should be manufactured in accordance with drawings and technical documents approved through prescribed procedures and comply with the provisions of these technical conditions.
2. Appearance quality and grading regulations: The appearance quality and grading regulations of flange seals comply with the requirements of relevant standards.
3. Physical and mechanical properties: The physical and mechanical properties of flange seals should meet the requirements of relevant standards, including hardness, elastic modulus, oil resistance, high-temperature resistance, wear resistance aging resistance, etc.
4. Dimensions and tolerances: The dimensions and tolerances of flange rubber seals should comply with the requirements of relevant standards to ensure correct coordination with connected pipelines and equipment.
Application Industries
■ Chemical industry: Rubber flange seals are widely used in various chemical equipment, such as reactors, centrifuges, compressors, etc. Since chemical media are usually corrosive, flammable, and explosive, rubber seals with corrosion resistance and high reliability are needed to ensure the safety and stability of the equipment.
■ Food industry: Rubber seals are used in beverage filling machines, food packaging machines, etc. Food processing equipment needs to ensure food safety and hygiene.
■ Shipping industry: Flange seals are widely used in marine diesel engines, ship piping systems, etc. to ensure the safety and stability of equipment.
In short, rubber flange seals are widely used in many fields. These cases show that they have the advantages of high reliability, high durability, and high safety, and can provide reliable guarantees for the safe and stable operation of various equipment.
