FAQ

Q1: What corrosive media can this PTFE hose resist?
A1: PTFE is virtually inert to almost all chemicals. It is ideal for transferring high-purity acids, alkalis, solvents, and intermediates in fine chemical processes.

Q2: How is the flexibility achieved, and what is the minimum bend radius?
A2: The hose is manufactured with a special extrusion or corrugated design to provide excellent flexibility. The minimum bend radius can be as low as 4-6 times the outer diameter (depending on diameter and wall thickness), allowing easy routing in compact equipment layouts, reducing the need for elbows and lowering system pressure drop.

Q3: What are the continuous and short-term operating temperature limits?
A3: Continuous service temperature ranges from -70°C to +260°C, with short-term exposure (e.g., steam cleaning) up to 280°C. Within this range, the material retains chemical inertness and mechanical integrity without softening or degradation.

Q4: What working pressure can this hose withstand? What is the burst pressure?
A4: Working pressure depends on the inner diameter and wall thickness, typically ranging from 0.5 to 2.5 MPa for smooth-wall hoses, or 1.0 to 4.0 MPa for braid-reinforced versions (optional). Burst pressure is generally 3-5 times the working pressure. For higher pressure requirements, we offer reinforced hoses with stainless steel wire braiding.

Q7: How smooth is the inner surface? Is it suitable for high-purity or crystallizing fluids?
A7: The inner surface has a roughness Ra ≤ 0.4μm and an extremely low friction coefficient, minimizing fluid retention or crystal adhesion. For high-purity chemicals or polymerizable media, it reduces contamination risks and cleaning frequency.

Q10: What are typical applications for this hose in the fine chemical industry, and what is its service life?
A10: Common uses include reactor feed/discharge lines, pump suction/discharge flexible connections, sampling lines, filling systems, and mobile tanker loading/unloading. Under normal operating conditions, the hose can last several years with no extractables affecting product purity. Regular visual inspection and fitting retightening further extend service life.
