Frequently Asked Questions
Q1: What is the difference between a spiral filter tube and a conventional filter cartridge?
A: Spiral filter tubes have a wedge wire structure that provides a higher open area, better flow distribution, and easier backwashing. They are more durable and reusable, while conventional cartridges often need frequent replacement.
Q2: Can I use this filter tube for viscous liquids?
A: Yes, the spiral design reduces clogging and can handle moderate viscosity liquids. For very high viscosity, we recommend selecting a larger slot size or consulting our engineers for a customized solution.
Q3: What is the maximum pressure and temperature this tube can withstand?
A: Standard models handle up to 6.0 MPa (60 bar) and 600°C. For higher pressure or temperature, special materials and designs are available upon request.
Q4: How often should the filter tube be cleaned?
A: Cleaning frequency depends on the particle load and liquid conditions. Typically, backwashing every few days to weeks is sufficient. The tube can be cleaned multiple times without performance loss.
Q5: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 100 mm length) for evaluation. Please contact our sales team to discuss your requirements.
Q6: What are the available end connections?
A: We offer threaded (NPT, BSP), flanged, and plain ends. Custom connections (e.g., grooved, sanitary tri-clamp) can be made to order.
Q7: Is the filter tube suitable for food and beverage applications?
A: Yes, when made from 316L stainless steel with a polished finish, it meets hygiene standards for food contact. We can provide materials with appropriate certifications upon request.
Q8: What is the typical lead time?
A: For standard sizes and quantities, lead time is about 15-20 working days. Custom orders may take 25-30 days. Urgent orders can be expedited upon request.
