Large bore filter

A filter is a product capable of removing solid particulate impurities, improving the purity of the product and guaranteeing safety of downstream equipment (condenser, pump, dashboard etc.)
application industry:
1 Chemical and petrochemical production in the weak corrosion of materials, such as: water, ammonia, oil, etc..
Corrosive materials, chemical products in 2 such as caustic soda, soda ash, sulfuric acid, sulfuric acid, acetic acid, etc..
3 cold in the low temperature of the material, such as: liquid methane, ammonia, oxygen and refrigerant.
4 light industrial food, pharmaceutical production in the health requirements of the materials, such as: beer, beverages, dairy products, food and beverage supplies, etc..

Main Technical Parameter 1.Cartridge of Strainers Material: stainless steel.
2.Flange standard: HG20592-2009 PN1.0 (Please mark in the contract, if you need to adopt GB, SH, JB, ANSI, DIN or JIS or to change pressure levels.).
3.Standard of manufacture and examination: SH/T3411-1999, HG/T31637-1991 or standard adopted by customers..

maintenance methods:
1 the core part of the filter is the filter core, filter core is composed of filter box and stainless steel wire mesh, stainless steel wire mesh is a suitable loss, need special protection;
2 when the filter works for a period of time, the filter core precipitation of a certain impurity, then the pressure drop increases, the flow rate will drop, need to promptly remove impurities in the filter core;
3. The impurities are cleaned, special attention to filter on the stainless steel wire mesh can not be deformed or damaged. Otherwise, then installed filters, filter medium purity is not up to the design requirements, compressors, pumps, instruments and other equipment will be destroyed; < br > 4 if it is found that the stainless steel wire mesh deformation or damage, need to be replaced immediately.
