Dust removal accessory sealing gasket: resistant to high and low temperatures, leak proof, adaptable to multiple working conditions
Oct 04,2025
In overseas industrial dust removal systems, the sealing gasket is often overlooked, but it directly determines whether the equipment "leaks air beyond the standard". Ordinary sealing gaskets are prone to aging and cracking under high and low temperature, corrosive conditions, leading to dust leakage. This not only triggers environmental fines, but also increases fan energy consumption by 20%. And the high and low temperature resistant leak proof sealing gasket, relying on special materials and structural design, has become the "leak proof key" of dust removal equipment, suitable for foreign trade scenarios in multiple industries such as chemical, metallurgical, and food.
1、 High and low temperature resistance: able to withstand extreme working conditions without aging or cracking
The temperature difference is large in different regions, and the sealing gasket needs to be accurately matched with the temperature range to avoid failure:
1. Wide temperature range material, covering the entire scene
Normal temperature condition (-20 ℃~80 ℃): Choose nitrile rubber sealing gasket, suitable for Southeast Asian food factories and electronics factories, with low cost, good elasticity, and high adhesion;
Medium to high temperature conditions (80 ℃~200 ℃): Made of fluororubber material, resistant to oil and aging, suitable for chemical workshops in the Middle East and metallurgical plants in India, long-term use without deformation;
Ultra high temperature conditions (200 ℃~300 ℃): Choose graphite composite sealing gasket, which is heat-resistant and shock resistant, suitable for high-temperature dust removal systems in European and American steel plants and power plants, with a lifespan of over 3 years.
2. Compliant materials with no safety hazards
All sealing gasket materials have passed SGS testing and comply with EU REACH and US FDA standards. The gaskets used in food factories have no odor or migration, and the gaskets used in chemical scenes have no harmful substance precipitation. Customs clearance is unobstructed.
2、 Leak proof core: structure+adhesion, preventing dust leakage
The "leak proof ability" of gaskets comes from detailed design and precise adaptation:
1. Double sealed structure, strengthening leak prevention
Adopting a dual channel design of "main seal+auxiliary seal", the main seal layer tightly adheres to the equipment flange, and the auxiliary layer fills small gaps. The overall sealing level reaches IP65, which can prevent dust leakage from the flange gap even under negative pressure conditions, meeting the EU EN 13285 ultra-low emission requirements.
2. Curved fitting design, suitable for different devices
In response to the differences in flange shapes of bag filters, filter cartridges, and electrostatic precipitators, the sealing gasket is chamfered in an arc shape to perfectly fit the flange surface, avoiding the problem of "corner air leakage" caused by traditional straight edge gaskets; The thickness is customized according to the equipment pressure (3mm~8mm) to ensure that there is no gap after compression.
3、 Multi scenario adaptation: fully meet foreign trade needs
1. Customization of regional working conditions
High humidity scenarios (Northern Europe, Southeast Asia): sealing gasket with hydrophobic coating to prevent moisture swelling;
Corrosion scenarios (chemical, electroplating): Use acid alkali resistant fluororubber pads, resistant to pH 2-12 corrosion, to avoid water leakage due to corrosion within 3-6 months;
Explosion proof scenario (oil and gas chemical industry): Choose anti-static sealing gasket, surface resistance ≤ 10 ⁶ Ω, in compliance with ATEX certification requirements.
2. Equipment model adaptation
Provide standardized and customized services: regular models are available in stock, and special equipment can be customized according to drawings, suitable for different brands and models of dust removal equipment in overseas factories, and can be installed without modification.
For overseas factories, high and low temperature resistant leak proof gaskets are not "cheap accessories", but "invisible guardians" to ensure that dust removal systems meet standards and reduce energy consumption. Choosing the right gasket can not only avoid environmental fines and energy waste caused by air leakage, but also reduce frequent replacement and maintenance costs, perfectly adapting to diverse global working conditions.
