Frequently Asked Questions
Q1: What is the difference between 304 and 316L stainless steel for chemical filtration?
A: 316L contains molybdenum (2–3%) which greatly improves resistance to chlorides, acids, and pitting. For aggressive chemicals like hydrochloric acid or brine, 316L is the preferred choice. 304 is suitable for milder environments.
Q2: Can you customize the drum diameter and height?
A: Yes, we offer full customization. You can specify the outer diameter, height, wall thickness, perforation pattern, and end cap style. Minimum order quantity may apply for non-standard sizes.
Q3: How do I clean the filter drum after use?
A: The drum can be cleaned by backwashing with water or solvent, ultrasonic cleaning, or manual brushing. For caked residues, chemical cleaning with mild detergents is recommended. Avoid abrasive tools that may damage the surface.
Q4: What is the maximum operating temperature for this drum?
A: 316L stainless steel can withstand continuous temperatures up to 800°C (1472°F) in air, but for filtration applications with chemical exposure, the safe limit is typically around 400°C (752°F). For high-temperature processes, please consult our engineers.
Q5: Do you provide samples before mass production?
A: Absolutely. We can produce a sample according to your drawing or dimensions. Sample cost is negotiable, and we will refund the sample fee upon bulk order placement.
Q6: How long is the lead time for standard drums?
A: For standard sizes (e.g., 300mm diameter x 500mm height), lead time is approximately 15–20 working days after order confirmation. Custom orders may require 25–30 days depending on complexity.
Q7: Is the drum suitable for pressure filtration systems?
A: Yes, with appropriate wall thickness and welding design, the drum can be used in pressure vessels up to 10 bar (145 psi). Please specify your pressure requirements during inquiry so we can optimize the design.
Q8: What is the packaging for export?
A: Each drum is individually wrapped with protective film, then packed in reinforced wooden crates or cartons. For large orders, we use palletized packaging with steel strapping to ensure safe transit.
