Drawing-based components
PTFE liners, sleeves and fitted contact barriers for equipment surfaces and fluid paths. Define support, retention and the exposed process media.
Procurement specification
These components are made to the required geometry. The drawing defines the finished dimensions and interfaces.
| Liner forms | Sleeve, shaped insert or cut contact barrier |
|---|---|
| Exposed duty | Media, temperature and cleaning conditions |
| Fit | Host equipment dimensions and insertion clearance |
| Retention | Mechanical support or specified bonding arrangement |
| Pressure context | Supported assembly and differential pressure |
A liner depends on the surrounding equipment for support and positioning. Provide the host bore, flange detail or cavity so the insert fits without blocking the intended flow path.
Show any stops, lips or retained edges. A liner that can move with thermal cycling or pressure changes needs an installation arrangement that controls that movement.
The media and cleaning cycle determine the material discussion. Include concentration and operating temperature rather than identifying only a broad chemical family.
A free-standing sleeve and a supported equipment liner have different mechanical duties. Do not assign the host equipment pressure rating to an unsupported PTFE insert.
Specific answers
No. State the retention method. Adhesive bonding requires a suitable treated surface and a compatible adhesive system.
The bore is only part of the specification. Length, wall, retention, temperature and process conditions also affect the fit.
Quote the component
Provide host equipment dimensions, liner profile, support and retention details, media, temperature and quantity. Include pressure conditions where applicable.
