ANSI/ASME Stainless Steel Flange Filters

ANSI/ASME stainless steel flange filters are high-performance pipeline filtration devices designed and manufactured in strict compliance with ANSI/ASME and relevant international standards. Adopting a flange connection structure and premium stainless steel materials, these filters are primarily used to remove solid impurities, particles, and contaminants from fluid media in industrial pipeline systems.

I. Product Introduction

The product features a compact and robust design, with the flange connection ensuring reliable sealing and easy installation, which is widely compatible with ANSI/ASME standard pipeline systems. It effectively protects downstream precision equipment such as valves, pumps, flow meters, and nozzles from abrasion, blockage, and damage, thereby extending the service life of the entire pipeline system and ensuring stable and efficient operation.

Suitable for a variety of harsh working conditions, ANSI/ASME stainless steel flange filters are widely applied in petroleum, chemical, food and beverage, pharmaceutical, water treatment, and power generation industries, adapting to different media types and operating parameters.

II. Product Features

High-Quality Material Selection

The main body, cover, and filter screen are made of high-grade stainless steel (such as SS316) and other corrosion-resistant alloys, providing excellent resistance to corrosion, high temperature, and pressure, and adapting to various corrosive media.
Standard Flange Connection

Strictly in line with ANSI B16.5 flange dimension standards, ensuring perfect compatibility with ANSI/ASME standard pipeline systems. The connection is firm and reliable, with good sealing performance, effectively preventing fluid leakage.
Efficient Filtration Performance

Equipped with high-precision stainless steel filter screens, the mesh total area can reach 3~4 times the nominal diameter (DN) of the pipeline, ensuring large flux and low pressure loss while efficiently intercepting impurities.
Easy Maintenance and Operation

The structure design is user-friendly for disassembly and cleaning. The discharge port and slideway bush parts are optimized for quick removal of the filter screen and cleaning of intercepted impurities without the need for complex tools, reducing maintenance time and costs.
Diversified Sealing Options

Providing multiple sealing materials such as PTFE, enhanced flexible graphite, and tooth profile gaskets to meet the sealing requirements of different working temperatures, pressures, and media types, ensuring long-term reliable sealing.
Wide Operating Range

Adapting to a wide range of nominal pressures and working temperatures, with different shell materials (such as CF8, CF8M, CF3, CF3M) available for selection, meeting the needs of various industrial working conditions.
