Our Stainless Steel Thread Strainer is a purpose-built pipeline filtration device, typically installed upstream of pressure reducing valves, pressure relief valves, metering equipment, and other sensitive process components. Its core function is to remove solid particles, suspended solids, and microbial contaminants from liquid and gaseous mediums, preventing equipment blockage, abrasion, and premature failure, while ensuring consistent product quality and compliance with industry-specific purity regulations.
Manufactured to ASME B16.34 design standards and tested in accordance with API598 inspection requirements, this 200WOG thread strainer features a standard size range of 1/2” to 2”, a pressure rating of 200WOG, and an operating temperature range of -19℃ to 180℃. It is compatible with NPT, BSPT, RC, and G thread ends for seamless pipeline integration, with valve body materials including CF8, CF8M, and CF3M stainless steel, and filter screens available in 304, 316, and 316L pharmaceutical-grade stainless steel. It is optimized for water, oil, and gas mediums, with custom configurations available for specialized process fluids.
Engineered with precision-woven stainless steel filter screens, our pharmaceutical fluid filtration thread strainer effectively removes sub-millimeter particulate contaminants, suspended solids, bacteria, and viruses from process fluids, ensuring full compliance with the strict purity requirements of pharmaceutical, food and beverage, and fine chemical manufacturing.
Fabricated from high-grade 304 and 316L stainless steel, this stainless steel thread strainer offers exceptional corrosion resistance, acid and alkali tolerance, and high-temperature stability, maintaining reliable performance in harsh process environments, extending service life, and reducing replacement frequency and long-term operational costs.
The strainer’s fully detachable threaded design enables quick, tool-free disassembly for filter screen cleaning, replacement, and system inspection, eliminating the need for specialized maintenance personnel or extensive pipeline shutdowns, and maximizing your facility’s operational uptime.
The precision-machined threaded connection, paired with high-performance PTFE gaskets, delivers a leak-proof, contamination-free seal, preventing unfiltered fluid bypass and external environmental contamination, which is critical for sanitary and sterile manufacturing processes.

Our stainless steel thread strainer is widely deployed across pharmaceutical, food and beverage, chemical processing, power generation, and petroleum industries, where fluid purity and equipment protection are critical. In pharmaceutical manufacturing, it is used to filter water for injection, infusion solutions, and active pharmaceutical ingredient (API) fluids to ensure drug safety and regulatory compliance. In food and beverage production, it filters process water, beverages, edible oils, and seasonings to uphold food safety standards. Additional applications include water treatment systems, chemical process lines, and industrial gas distribution networks.
