Customer application cases for PTFE hose with fittings
Case 1
Customer background: A multinational chemical company based in Belgium required replacement of its existing rubber hose system for conveying high-concentration nitric acid and hydrofluoric acid.
Customer requirements:
Compatibility with highly corrosive chemicals
Enhanced system pressure and temperature resistance
Connectors must be compatible with existing equipment interfaces
Solution:
Provide inner layer corrosion-resistant PTFE tubing, outer layer 304 stainless steel braided reinforcement, with matching stainless steel flange connectors (ANSI standard), and custom-made tubing assemblies. Each set undergoes hydrostatic pressure testing and airtightness testing before shipment.
Customer Feedback: The system has operated for over two years with zero leaks, reducing pipeline replacement frequency and manual inspection time.
Case 2
Customer Background: A GMP pharmaceutical plant in the eastern United States, constructing a new cell culture facility, requiring pipes with high pressure resistance, contamination-free properties, and high-temperature sterilization capability.
Customer Requirements: Materials compliant with FDA/USP Class VI certification
Suitable for CIP/SIP systems
Flexible connection to multiple reactor units
Solution: Customized food-grade PTFE hose assemblies paired with 316L stainless steel quick-connect fittings (TC), with blue silicone protective sleeves for visual identification. The product has passed third-party material and cleanliness certification.
Customer Feedback: The project passed validation on the first attempt. Replacing the original PVC hoses improved cleaning efficiency and prevented cross-contamination between batches.
Case 3
Customer Background: A Taiwanese wafer fab project requiring the construction of high-purity fluorine gas, nitrogen gas, and other special gas lines, necessitating the use of clean-grade PTFE hoses.
Customer Requirements: Ultra-clean, no leaching, corrosion-resistant
Fully sealed system with no leaks
Suitable for Class 100 cleanroom environments
Solution: Customized clean-grade PTFE corrugated hose assemblies with dual ferrule airtight connectors (Swagelok standard), accompanied by helium mass spectrometry leak test reports and cleanliness grade certifications.
Customer Feedback: Complies with cleanroom environmental management standards, enhances process gas stability, and provides bulk supply for multiple subsequent factory sites.
