1. Rapid Assembly: Socket Fusion Fittings utilize a hot-melt socket welding process. Welding is completed simply by inserting the pipe into the sleeve and heating for tens of seconds. The overall operation time is significantly shorter than the minutes or even hours required for traditional arc or gas welding. 2. Low O...
View More1. High Temperature Resistance Taking fluoroplastics (PTFE, FEP, PVDF, ETFE, PFA) as an example, their maximum operating temperature can reach 260℃, with a low temperature limit above -18℃. Conventional plastic piping (such as PPR and PVC) can be used stably for a long time below 90℃, but softening or even failure will...
View More1. Determine the Media Characteristics First, determine whether the medium being transported by the plastic pipe is water, oil, chemical solvents, or gas. Select materials based on its corrosiveness, viscosity, and temperature range. PPR is suitable for hot water, PVC for acid and alkali media, and PE-RT for low-temper...
View MoreWhat is a Flanged Spacer?
1. Definition: A flanged spacer is a metal or composite material gasket used in piping systems to connect flanges. It provides sealing, support, and positioning between two flanges, preventing leaks and absorbing vibration.
2. Structural Features: Common structures include flat gaskets, gaskets with locating rings, and gaskets with movable locating rings. Materials include flexible graphite, PTFE, and serrated metal, to adapt to different operating conditions, temperatures, pressures, and chemical media.
3. Applications: Widely used in piping systems in industries such as solar photovoltaic, semiconductors, chemicals, iron smelting, environmental protection, biochemistry, aquaculture, and pharmaceuticals, meeting the sealing requirements of high-temperature, high-pressure, or corrosive media.
How is a Flanged Spacer Positioned in Mechanical Assembly?
1. Flange Face Positioning
The flanged spacer is placed between the sealing surfaces of the two flanges. The center hole of the gasket is aligned with the pipe or bolt hole to achieve precise axial positioning.
2. Bolt Pre-tightening Positioning
By evenly tightening the bolts, the gasket is compressed and undergoes elastic deformation, creating a uniform sealing pressure. The bolt pre-tightening force simultaneously locks the gasket in position, preventing displacement during operation.
3. Locating Ring Assistance
For flanged spacers with locating rings, the rings directly engage with the flange flange, providing additional radial support and ensuring the gasket maintains accurate positioning even under high vibration or shock environments.
4. Vibration Isolation and Compensation
The flexible material of the gasket absorbs the thermal expansion and mechanical vibration of the pipeline, maintaining the relative position between the flanges and reducing the risk of leakage.
