Product Introduction
PVC industrial flange spacers are annular fittings installed between flange joints to fill minute gaps and enhance sealing. They are widely used in water supply, drainage, ventilation, and some chemical pipelines.
Product Features
Excellent Sealing Performance
PVC industrial flange spacers exhibit excellent resilience. When compressed, they adhere tightly to the flange contact surface and fill minute gaps, preventing leakage through the joint. They can maintain leak-free performance for extended periods at a pressure of 0.6 MPa.
UV-Resistant
PVC industrial flange gaskets are formulated with UV absorbers and light stabilizers to absorb and disperse UV light, inhibiting photooxidation, ensuring they resist powdering or cracking for 5-8 years of outdoor use.
High Chemical Resistance
PVC industrial flange gaskets are made of polyvinyl chloride (PVC), which is virtually unreactive with most chemical solutions and maintains stable performance in chemical media within a pH range of 2-11.
Specifications and models
PVC industrial water supply flange gaskets have a variety of specifications and models to meet different pipeline systems and application requirements. Common specifications include DN25, DN50, DN65, DN80, DN100, etc. The specific selection depends on the size and pressure level of the pipeline system.
Application Field
Water Supply Pipes
PVC industrial flange gaskets are used at flange connections in municipal and industrial water supply pipelines to ensure a tight seal and prevent water leakage during transport.
Drainage Systems
PVC industrial flange gaskets are used at the joints of various drainage pipes to prevent leakage of sewage or rainwater during discharge.
Ventilation Pipes
PVC industrial flange gaskets are used at flange connections in ventilation systems to prevent air leakage and ensure that air supply or exhaust efficiency meets design requirements.
Chemical Pipes
PVC industrial flange gaskets are used to seal the joints of chemical media pipelines, preventing the leakage of chemical liquids or gases during transport.
Seawater Transportation
PVC industrial flange gaskets are used at flange connections in seawater transportation pipelines to prevent saltwater leakage.
FAQ
Q: What is the production cycle for your PVC industrial flange spacers?
A: Standard PVC industrial flange gaskets can be produced and shipped within 7-10 business days. For custom specifications, production lead times vary depending on design complexity and quantity, but typically take less than 15 business days.
Q: Can PVC industrial flange gaskets be customized in size and bolt hole locations?
A: Yes, we offer a full range of customization services, including customization of parameters such as inner diameter, outer diameter, thickness, number and location of bolt holes, and more.
Q: What are the standard sizes and specifications for PVC industrial flange gaskets?
A: Standard sizes include diameters from DN15 to DN600, with thicknesses generally ranging from 2mm to 5mm. Bolt hole sizes and quantities comply with various flange standards, including national, American, and European standards.
Q: What surface treatment options are available?
A: Surface flatness and deburring can be performed before shipment to ensure a high fit between the flange mating surfaces and minimize damage to the gasket or flange surface during installation.
