Frequently Asked Questions
-
Q: What is the advantage of 316L stainless steel over 304?
A: 316L contains molybdenum, offering superior resistance to chlorides, acids, and pitting — ideal for seawater, chemical, and high-temperature applications. -
Q: Can the 0.2mm slot filter particles larger than 200 microns?
A: Yes, the nominal filtration rating is ~200 microns, meaning it will retain most particles ≥200 microns, with some smaller particles depending on shape and flow conditions. -
Q: How do I clean this wedge filter?
A: The smooth wedge profile allows effective backwashing, air scouring, or chemical cleaning. For heavy fouling, ultrasonic cleaning is also possible. -
Q: Is the 1.2m length fixed or can it be customized?
A: We offer customization — lengths from 0.1m to 6m can be manufactured upon request. Please specify your required dimensions. -
Q: In which industries is this filter commonly used?
A: It is widely used in water treatment, oil & gas, petrochemical, food & beverage, mining, pulp & paper, and irrigation filtration. -
Q: Does the filter meet any international standards?
A: Our filters are manufactured in compliance with general industry standards for wedge wire screens. Specific certifications can be provided upon request. -
Q: What end connections are available?
A: Threaded (NPT/BSP), flanged, welded, or plain ends are available. We can also add gaskets or O-rings as needed. -
Q: What is the typical pressure rating?
A: The pressure rating depends on diameter, wall thickness, and end connections. For standard 1.2m length, it can withstand up to 10 bar (145 psi); higher ratings are available with reinforced designs.
