Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316L and 316 stainless steel?
A: 316L has lower carbon content (max 0.03%) compared to 316 (max 0.08%), which improves weldability and reduces risk of intergranular corrosion after welding. It is preferred for applications requiring high corrosion resistance. -
Q: Can you provide a sample before mass production?
A: Yes, we can produce samples based on your specifications. Sample cost and shipping will be discussed; sample fee is refundable for bulk orders. -
Q: What is the tolerance for the 0.2mm slot?
A: Standard tolerance is ±0.02mm. Tighter tolerances can be achieved upon request at additional cost. -
Q: How long is the warranty period?
A: We offer a 1-year warranty against manufacturing defects. Damage caused by improper use or installation is not covered. -
Q: Do you provide Mill Test Reports?
A: Yes, a Mill Test Report (MTR) is included with each shipment, confirming the chemical composition and mechanical properties of the 316L stainless steel. -
Q: Can you customize the screen diameter and length?
A: Absolutely. We can produce screens with various diameters (from 25mm to 600mm) and lengths up to 6000mm. End connections can be customized as well. -
Q: What is the maximum working pressure?
A: The maximum pressure depends on the screen diameter, wall thickness, and support rod design. Typically, our screens can withstand up to 10 bar. Please provide your operating conditions for a precise recommendation. -
