Product Introduction

  The KRTG1B4F strainer is an indispensable device in the pipe system that conveys gas and other media. It is generally used in such transportation and distribution systems as gas off-take stations, gas distribution stations and gas stations, playing its important role in protecting pressure controllers, flow meters, valves and other equipment in the system.

Features of Product

1. It is used to filter particulate impurities in natural gas, liquefied petroleum gas and other transport media, and protect the valves, flow meters, pressure regulation and other equipment.

2. The strainer is composed of shell, filter element, removable flange (or quick opening device) upper cover and sewage outlet. Removable flange cover is convenient for removing or replacing the filter element.

3. The filter element of KMO is made of stainless steel wire mesh or non-woven fabric. The filter area is large and the pressure loss is small. The filtered particles are concentrated at the bottom of the filter and discharged from the sewage outlet. The stainless steel wire mesh filter element can be washed and reused many times.

4. The filter screen can be set according to the user's needs. The filter accuracy is generally divided into 5μm (non-woven fabric), 20μm and 50μm.

5. The product can be optionally equipped with a differential pressure gauge. When the filter screen is blocked and the pressure loss value increases, please remove and wash the filter element or replace a new one.

6. The product has such features, like small body shape, high filtration accuracy, good filtration effect, low cost, short drainage time, and easy to install and maintain. For small models, it only takes 5-10 minutes to install.

Notes for Use

1. Keep the filter cavity clean before installation to prevent impurities from entering and affecting the use effect.

2. When the strainer is tested for hydraulic strength, the intake valve should be closed firstly. After the test is completed, use 0.6MPA air pressure to conduct airtightness test on the strainer, differential pressure gauge and pressure guide tube. After the pressure is stabilized, opening the two intake valves slowly at the same time to avoid damage to the differential pressure gauge caused by excessive unilateral pressure 

3. According to the working conditions on site, it is recommended to periodically drain and clean the filter.

4. KMO reminds the user that it is necessary to clean the filter element when the differential pressure gauge shows that the difference of the inlet and outlet pressure reaches 0.03MPA (or specified by the user). The cleaning step is that: ①cutting of the inlet and outlet valves of the filter to ensure that there is no pressure and medium in the inner cavity; ②taking out the detachable filter element and using a brush to gently remove impurities; ③reloading. If the cleanliness of the filter element still cannot meet the demand after cleaning, it is recommended to replace with a new filter element.

5. After each cleaning, you need to re-test to ensure the tightness of the product, and replace the air in the filter with nitrogen.

6. Closing the intake valve before venting, after the pressure is stable then slowly open the two intake valves at the same time , to avoid damage to the differential pressure gauge caused by excessive unilateral pressure.
