Frequently Asked Questions
Q1: What is the difference between a wedge filter and a Johnson filter?
A: Johnson filter is a specific brand of wedge wire screen, but the term is often used generically. Our product uses the same wedge wire construction with continuous V-shaped slot, so it functions identically. We offer both standard and custom designs.
Q2: Can you provide a Mill Test Report for each batch?
A: Yes, we include a Mill Test Report (MTR) per batch of material, certifying chemical composition and mechanical properties. This is standard for our production.
Q3: What is the typical lead time?
A: For standard sizes (e.g., 100mm diameter x 1m length), lead time is about 15-20 working days. Custom orders may take 25-30 days depending on complexity. We can expedite for urgent requirements.
Q4: How do you ensure the slot width accuracy?
A: We use CNC-controlled winding machines and perform 100% inspection with feeler gauges. The tolerance is within ±0.02 mm for slots up to 1 mm, and ±0.05 mm for larger slots.
Q5: What is the maximum operating temperature and pressure?
A: For SS316L, the maximum continuous operating temperature is 400°C (752°F). Pressure rating depends on diameter and wall thickness; typical wedge screens can withstand up to 10 bar differential pressure. For higher pressure, we can reinforce the support structure.
Q6: Do you offer samples for testing?
A: Yes, we can provide small sample pieces (e.g., 200mm long) for evaluation. The sample cost is low, and we deduct it from the bulk order. Shipping is at the buyer's cost.
Q7: How do I clean the wedge filter?
A: The V-shaped profile allows easy backwashing. For light fouling, simple reverse flow cleaning is sufficient. For heavy deposits, chemical cleaning or high-pressure water jet can be used. The design minimizes permanent clogging.
Q8: Can you customize the end connections?
A: Absolutely. We can weld flanges (ANSI, DIN, JIS), threads (NPT, BSP), or other custom ends. Please specify your requirements when ordering.
