High-Performance stainless steel pipeline strainer

ZERRU Pipeline Strainers is an indispensable pipeline accessory in industrial production.It is Installed  in the pipeline can filter out the solid impurities in the liquid, to ensure the normal operation of the pipeline equipment system, can make the liquid more pure, and obtain the ideal industrial products.

After working for a period of time, open the cover and take out the basket, wash the brush can be restored as    new, therefore, it is have been widely used in the petroleum, chemical, pharmaceutical, food and other industries.

概述general description

1. Strainer is designed, manufactured and inspected according to HG/T 21637-1991 and SHT3411-1999.
2. The filter flange standard is based on HG/T20592-2009. Please indicate other flange standards: such as GB, ANSI, ASME, HGJ, DIN, JIS, etc.
3. The connection forms of the filter include (loose sleeve) flange type, welding type, threaded type, quick-install type, etc.
4. The filter element is generally made of stainless steel wire mesh. Users can also choose perforated mesh, wedge-shaped wire mesh or five-layer sintered mesh as the filter element.

工作介质Application

1. The main materials applicable are: weakly corrosive materials in chemical and petrochemical production. Such as: water, ammonia, oil, hydrogen.
2. Corrosive materials in chemical production: caustic soda, soda ash, concentrated and dilute sulfuric acid, nitric acid, fat, etc.
3. Low-temperature materials in refrigeration and air separation production: beer, beverages, dairy products, syrup, medical supplies, etc. Generally, the filter material should be selected according to the corrosion of the medium to the material.
