Our service
Chunhuan Group (Zhenjiang Chunhuan Sealing Group Co., Ltd.), established in 1985, is a leading manufacturer of fluoroplastic products, chemical semiconductor linings, and new energy sealing gaskets. The company primarily focuses on the research, development, and production of fluoroplastic series sealing products (for hydrogen energy and nuclear power applications) and chemical semiconductor linings. With subsidiaries in South Korea and Shanghai, the group has also established a joint venture with South Korea's Houcheng Group for semiconductor lining equipment. Main production: PTFE products, metal seals series, steel lining anti-corrosion series, engineering plastics series,rubber products series,it is the leading enterprise in the national fluoroplastics industry. The company supplies more than 300 varieties of PTFE composite modified materials,ranging from standard composite modified materials (bronze,glass fiber,carbon,graphite,etc.) to customized solutions to meet different production needs of customers.The company provides flexible quantity and fast delivery service. The engineers have 35 years working experience in the field of PTFE,serving customers in more than 30 countries.
Q1: What is the material purity of this PTFE tube? Does it meet USP Class VI or FDA requirements?
A1: We use 100% virgin PTFE resin (no regrind), compliant with FDA 21 CFR 177.1550, and can supply USP Class VI biocompatibility test reports to meet the strict demands of pharmaceutical and biotech high-purity systems.
Q2: What inner surface roughness can you achieve, and how do you prevent particle shedding?
A2: Through precision extrusion or skiving, we achieve an inner surface roughness Ra ≤ 0.4 μm, with no bubbles, cracks, or inclusions, effectively minimizing particle release and maintaining fluid purity.
Q3: Can you provide full batch traceability documentation, and what does it include?
A3: Yes. Each batch is supplied with a batch number, raw material certificate, physical property test data (density, tensile strength, etc.), and optional extractable/endotoxin test reports to support GMP audits.
Q4: Do you support filled modifications, such as anti-static or reinforced grades?
A4: Yes. We can add fillers like carbon fiber, glass fiber, or graphite to improve anti-static or mechanical strength upon request. However, note that fillers may affect cleanroom compatibility; we will provide a suitability evaluation.
Q5: Can this tube withstand high-temperature steam sterilization (e.g., 121°C autoclave)?
A5: PTFE itself resists continuous service up to 260°C, so routine steam sterilization is no problem. However, sealing connections require careful design; we can provide sterilization cycle recommendations.
Q6: What connection options are available? Can you machine flared ends, flanges, or threaded adapters?
A6: We can machine flared ends, lap-joint flanges, integral flanges, or custom threaded fittings per your drawing, and also offer welding or bonding suggestions for seamless integration.
Q7: What are the working pressure and temperature ranges?
A7: Continuous service temperature ranges from -200°C to +260°C. Working pressure depends on wall thickness and diameter; typical thin-wall tubes handle up to 1.0 MPa at room temperature, while thicker walls can go higher. We calculate safe pressure based on your conditions.
Q8: Is the tube resistant to common cleaning agents used in biopharma?
A8: PTFE exhibits excellent resistance to almost all chemicals, including strong alkalis and oxidizers. However, concentration and temperature specifics matter - our engineers will provide compatibility data based on your cleaning protocol.
