Brief introduction of raw materials of stainless steel filter element for natural gas pipeline
Stainless steel filter element of natural gas pipeline is widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, city, household and other gas fields. The filter element of natural gas pipeline is an indispensable device in conveying medium pipeline, which is usually installed at the inlet end of pressure relief valve, pressure relief valve, positioning valve or other equipment to eliminate impurities in medium, to protect the normal use of valves and equipment, reduce equipment maintenance costs. When the fluid enters the filter with the natural gas pipeline filter element, its impurity is blocked by the filter element, and the clean filter gas is discharged by the filter outlet, the filter element of the natural gas pipeline can be taken out and reloaded after cleaning. Therefore, the use and maintenance of the filter element of the natural gas pipeline are extremely convenient. Natural gas pipeline filter element is made of screen material, but how the screen is woven, here is a brief introduction: natural gas pipeline filter mesh weave there are three kinds: plain, twill and satin. In general, plain filter structure compact, small pores, it is a good particle interception, high clarity of filtrate, long service life, the price is cheaper. The disadvantages are high specific resistance, easy blocking, poor slag discharge performance. Satin weaving fabric has the largest pores, small specific resistance, not easily blocked, good slag discharge performance. But the particle interception ability is low, the filtration is serious, and the filtration effect is poor. The various properties of the twill filter in the middle, anti-friction ability is very strong, filtering speed is also large, the longest life, so it is widely used. The characteristics of natural gas pipeline filter core are as follows: complex impurity content at gas well outlet; high water content, mixed with sediment, corrosive debris of front pipeline and equipment; need to filter by stages to remove liquid and solid impurities and recover useful components.
