Limit Rod PTFE Lined Rubber Joint

• High-strength metal limit rods precisely cap maximum displacement to prevent pull-apart failure
• PTFE inner liner delivers strong corrosion resistance for aggressive chemical process media
• Rubber body provides vibration damping and stress relief to protect pump and compressor connections
• Designed for high-pressure corrosive pipelines with water hammer or pressure surge risks

This joint fits high-pressure corrosive medium process piping at chemical production sites, blocking over-displacement caused pull-out failure while preserving anti-corrosion liner performance for hazardous chemical medium conveying circuits. It also operates on piping experiencing frequent pump start-stop events or rapid valve switching cycles, where limit rod hardware absorbs transient water hammer impact loads to prevent joint damage.

Henan Fuwei Pipeline Equipment Manufacturing Co., Ltd. varies limit rod material grade and mechanical strength rating matching pipeline working pressure parameters. Limit travel adjustment ranges can be re-calibrated according to site-specific displacement requirements. PTFE liner thickness grades and flange pressure class specifications are configurable. Custom sample development runs 15–20 day cycles with an MOQ set to 10 units.

Test sequences incorporate tensile strength assessment for limit rod assemblies and simulated water hammer impact trials alongside PTFE liner spark detector scanning and hydrostatic sealing tests. Every finished unit undergoes full item inspection pre-shipment, third-party inspection is allowed, and products carry a 24-month warranty.

Limit rod assemblies pack separately, and threaded rod ends install protective plastic end caps. Inner rubber joint bore surfaces apply protective film layers. Reinforced cartons or wooden crates hold assembled goods with internal cushion filler stopping rod deformation and rubber surface scratching during transit. Standard 20-foot container orders finish production within 30-day cycles, and safety-oriented custom specification products follow a 40–50 day lead time and adhere to strict inspection sequence scheduling.

• Limit travel can be adjusted on-site during installation by setting stop nut position
• Stainless steel limit rods are available for corrosive ambient environments
• Limit rod material and strength rating can be specified to match line pressure

Share pipeline working pressure, medium corrosion properties and expected maximum displacement value, and engineering staff will work out matched limit rod configuration suggestions.
