Stainless steel gas-liquid filter screen

Stainless steel gas-liquid filter screen is made of steel that is resistant to weak corrosive media such as air, steam, water, and chemical corrosive media such as acid, alkali, and salt. Also known as stainless and acid resistant steel. In practical applications, steel that is resistant to weak corrosive media corrosion is often referred to as stainless steel, while steel that is resistant to chemical media corrosion is referred to as acid resistant steel. Due to the differences in chemical composition between the two, the former may not necessarily be resistant to chemical medium corrosion, while the latter generally has rust resistance. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is a fundamental element that enables stainless steel to achieve corrosion resistance. When the chromium content in the steel reaches about 12%, chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the surface of the steel, which can prevent further corrosion of the steel substrate.

Detailed classification of stainless steel gas-liquid filter screens:

304 stainless steel gas-liquid filter screen

304 is a versatile stainless steel widely used in the production of equipment and components that require good comprehensive performance (corrosion resistance and formability). 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. 304 is equivalent to 0Cr18Ni9 stainless steel in China. 304 contains 17% chromium and 8% nickel. 304 is the most widely used stainless steel and heat-resistant steel. Used for food production equipment, chemical equipment, etc.

304L stainless steel gas-liquid filter screen

304L stainless steel is a versatile stainless steel material, and 304L is a variant of 304 stainless steel with lower carbon content, used in situations where welding is required. The lower carbon content minimizes the precipitation of carbides in the Heat-affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in some environments.

316 stainless steel gas-liquid filter screen

316 has excellent corrosion resistance, atmospheric corrosion resistance, and high-temperature strength due to the addition of molybdenum, making it suitable for use under harsh conditions; Excellent work hardening property (non-magnetic). Equipment used in seawater, chemical, dye, papermaking, oxalic acid, fertilizer and other production equipment; Photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.

Detailed information of stainless steel gas-liquid filter screen HG/T21618-1998: The specifications of stainless steel gas-liquid filter screen for wire mesh demister include four standard specifications: SP, DP, HR, and HP. The specifications of stainless steel gas-liquid filter screens for wire mesh demister include: HG5-1404, HG5-1405, HG5-1406, and the standard number is Hu Q/SG12-1-79. The standard specifies three types of stainless steel gas-liquid filter screens, namely standard type, high-efficiency type, and high penetration type.

1、 Silk warp range: 0.10mm-0.55mm (commonly used silk warp is 0.20mm-0.25mm) Additionally, there are multiple strands of silk twisted together for weaving.

2、 Opening size: from (2 × 3mm to (4 × 5mm) and then to (12 × In addition, the opening size can be slightly adjusted according to customer requirements. The form of opening is the cross arrangement of large and small holes (the size of the holes in the length direction is consistent, but the width is different)

3、 Surface condition of stainless steel gas-liquid filter mesh: flat mesh surface and corrugated mesh surface pressed into waves (the width and depth of the waves vary)

4、 The width range of stainless steel gas-liquid filter screen: 40mm, 80mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm, etc.
