Product overview

Standard gas filter is an important equipment of gas transmission and distribution system, in the process of gas transmission, in order to ensure the normal operation of gas transmission and distribution equipment and instruments (such as: regulator, valve, flow meter, pressure gauge, etc.), it is necessary to install filters that meet the requirements of filtration accuracy to remove solid impurities in gas. The filter has three structural forms: Z-type through type, Y-type cross-type and G-type corner type. The product can also choose quick-opening device, differential pressure meter, differential pressure sensor, safety valve, discharge valve and blowdown valve according to user needs.

Product characteristics

1, the standard gas filter shell material can be selected carbon steel or alloy steel, etc., when the medium contains sulfur, such as corrosive substances, corrosion resistant materials should be selected. This product is widely used in urban gas, biogas, natural gas, liquefied petroleum, non-corrosive gas and air pipe network, and is suitable for various control devices, pressure regulators, flowmeters and pipe networks requiring high-density filtration requirements.

2, the standard gas filter is the use of stainless steel folding filter element as the filter core, installed in the pipeline to remove impurities in the pipeline, to protect the pressure regulating machine, valve, flow meter, pressure meter on the pipeline.

3, the standard gas filter is composed of a filter shell, a cylindrical stainless steel folding filter element, a differential pressure instrument, and a blowdown valve. Cylindrical stainless steel folding filter element accuracy up to 1 micron. Quick-opening blind plate is optional for quick opening of cover, cleaning or replacement of filter element.
