Tapered Bore Full Face Spacer: Thermoplastic Butterfly Valve Clearance for Lined Pipe Systems
A Tapered Bore Full Face Spacer is a precision-machined thermoplastic flange spacer designed with a beveled internal bore to accommodate the swing radius of butterfly valve discs. The tapered bore prevents interference during valve operation while maintaining full flange-face coverage for optimal sealing and load distribution.
Overview
SG-P manufactures Tapered Bore Full Face Spacers specifically for lined-pipe flange dimensions, ensuring accurate alignment, chemical resistance, and long-term performance in corrosive and non-metallic piping systems. These spacers are commonly used where additional spacing is required without disrupting flow or valve functionality.
What Is a Tapered Bore Full Face Spacer Used For?
Tapered Bore Full Face Spacers are used in piping systems incorporating butterfly valves, where standard straight-bore spacers could restrict valve movement or cause mechanical interference. The tapered internal profile allows the valve disc to open and close freely while preserving the integrity of the flange connection.
Typical uses include:
- Providing clearance for butterfly valve disc swing
- Adding spacing between flanges without flow restriction
- Preventing damage to valve components and liners
- Maintaining proper gasket compression and sealing
- Supporting system modifications or retrofits involving valves
