Frequently Asked Questions
Q1: What is the difference between a wedge wire screen and a wire mesh screen?
A: Wedge wire screens are made by wrapping V-shaped wire around support rods, creating a continuous slot that is less prone to clogging and offers higher strength compared to woven wire mesh. They are ideal for high-pressure and high-flow applications.
Q2: Can the 0.2mm slot size be customized to other values?
A: Yes, we offer slot sizes from 0.05mm to 10mm or more. The 0.2mm is a standard option, but we can produce custom slot widths to meet your specific filtration requirements.
Q3: What materials are available besides 316L stainless steel?
A: We also offer 304, 316, 904L, duplex stainless steel, and other alloys. 316L is recommended for corrosive environments and high-temperature applications.
Q4: How do I determine the correct diameter and length for my application?
A: The suitable dimensions depend on your system's flow rate, pressure drop, and installation space. Our technical team can help you calculate the optimal size. Please provide your operating parameters for a recommendation.
Q5: Is this product suitable for sand control in oil wells?
A: Yes, Johnson screens are widely used for sand control in oil and gas wells. The wedge wire design prevents sand from entering while allowing fluid to pass. The 0.2mm slot is suitable for fine sand formations.
Q6: What is the typical lead time for custom orders?
A: Standard lead time is 15–25 days depending on quantity and complexity. We can expedite orders for urgent projects. Contact us for a precise timeline.
Q7: Do you provide free samples for testing?
A: Yes, we offer sample pieces for evaluation. Please note that shipping costs may apply. Sample orders are welcome to verify quality and performance.
Q8: How do you ensure the slot size accuracy?
A: We use advanced laser measurement and gauge inspection during production. Each filter is individually tested for slot uniformity and mechanical strength before shipment.
