GL61 forged steel ANSI strainer is a high-performance filtration device strictly designed and manufactured in accordance with ANSI/ASME standards. It is used in industrial pipelines to remove solid impurities and protect the stable operation of system equipment. This series of strainers is primarily made of high-quality forged steel (such as A105, F304, F316, etc.) through integral forging, featuring a dense metallic structure with excellent pressure-bearing capacity and impact resistance, capable of meeting demanding requirements from ambient to high temperature and high pressure conditions. Key pressure-containing parts, such as the body and cover, undergo precision machining to ensure compliance with wall thickness and strength requirements for various pressure ratings from Class 150 to Class 2500. Depending on media characteristics and operating temperatures, the sealing structure can flexibly utilize reinforced PTFE, flexible graphite, or stainless steel spiral wound gaskets to ensure superior sealing integrity under high-pressure fluctuations. As an indispensable precision protection unit in media-conveying pipeline systems, the GL61 ANSI strainer is typically installed at the inlet of pressure reducing valves, regulating valves, pumps, flow meters, or other automated equipment to efficiently intercept impurities such as weld slag and rust, thereby reducing equipment wear and preventing system blockages. GL61 forged steel ANSI strainer features a scientific structure, low flow resistance coefficient, and convenient blowdown operation. Its screen specifications can be customized according to actual application scenarios: generally 18-30 mesh for water, 10-100 mesh for gas, and up to 100-480 mesh for oil. It is widely used in industries with high equipment protection requirements such as petroleum, chemical, natural gas, and power.

1. High-grade mechanical properties and pressure resistance compliant with American standards:Strictly following ANSI/ASME design and manufacturing standards, the strainer is integrally forged from high-quality steel under high pressure, resulting in a fine and uniform metallic structure that completely eliminates casting defects. The product meets high-pressure requirements from Class 150 up to Class 2500, possessing exceptional tensile strength and toughness to ensure the safety of piping systems under high-pressure conditions and water hammer impacts.
2.Refined Y-pattern flow path and low-resistance design:The internal flow path fully complies with ANSI wall thickness and flow design specifications, featuring a smooth internal cavity that effectively reduces turbulence and pressure loss during media passage. Equipped with high-quality stainless steel precision screens, it provides a sufficient effective filtration area reserve, maintaining the rated flow of the network while providing long-term interception of mechanical impurities.
3.Tight sealing structure compliant with international specifications:The connection between the cover and body adopts precision threaded or flanged sealing forms that comply with ASME standards, with metallic spiral wound gaskets or high-grade flexible graphite seals selected according to pressure ratings. Precision CNC machining ensures a seamless fit and excellent sealing stability, making it particularly suitable for rigorous media such as high-pressure gases, petroleum, and natural gas.
4.Convenient standardized maintenance and online cleaning:The standardized structural design features a blowdown plug with ANSI NPT threads or a bolted flange cover at the bottom. Without dismantling the strainer from the pipeline, the cover can be quickly opened to remove the screen for cleaning, repair, or replacement, significantly shortening the maintenance downtime of industrial processes.
5.Broad adaptability to global industrial conditions:With superior forged steel quality and strict standardized interfaces, this series of strainers is widely used in international export projects within the chemical, refining, LNG, and power plant sectors. As a pre-protection device for various imported pumps, compressors, precision instruments, and automated control valves, it offers an extremely long service life and global interchangeability.
