Product Description
Outer ring(CGType) metal spiral wound gaske
The outer ring type metal spiral wound gasket is a type of gasket widely used in the field of industrial sealing. Its structure and performance design enable it to perform well under high temperature, high pressure and complex working conditions. The following is a detailed description of its uses and performance:
1. Applicable fields
* Petrochemical industry: used for high temperature and high pressure equipment such as reactors, heat exchangers, and pipe flanges.
* Power industry: Sealing of steam systems such as boilers and steam turbines.
* Nuclear industry: radiation and corrosion resistant scenarios.
* Oil refining and natural gas: flange connection seals for pipelines, valves, and pumps.
* Chemical industry: Sealing of highly corrosive media (adaptable materials required).
2. Applicable flange types 1. Applicable fields
* Petrochemical industry: used for high temperature and high pressure equipment such as reactors, heat exchangers, and pipe flanges.
* Power industry: Sealing of steam systems such as boilers and steam turbines.
* Nuclear industry: radiation and corrosion resistant scenarios.
* Oil refining and natural gas: flange connection seals for pipelines, valves, and pumps.
* Chemical industry: Sealing of highly corrosive media (adaptable materials required).
Mainly used for flat flange (FF) or raised face flange (RF), the outer ring design helps positioning and prevents installation deviation.
3. Applicable working conditions
* High temperature: long-term working temperature can reach 700°C (depending on the material).
* High pressure: the withstand pressure is usually more than 20MPa.
* Alternating load: suitable for scenes with frequent temperature or pressure fluctuations.
4.Performance characteristics
* Multi-layer sealing structure:Metal belts (such as 304/316 stainless steel, titanium alloy)** and non-metallic filling materials (graphite, PTFE, mica) are alternately wound, combining elasticity and strength. The outer ring (positioning ring) is usually made of the same material as the metal belt, providing mechanical support, preventing the winding layer from loosening, and simplifying installation and positioning.
* Excellent sealing:The combination of metal and non-metallic materials realizes "soft-hard" double sealing, which can adapt to small defects on the flange surface. High compression rebound rate (up to 40% or more when graphite is filled). compensating for flange deformation.
5. Installation points:
Control the bolt preload to avoid excessive compression that may cause the filling layer to fail. Check the flange surface roughness (usually Ra≤3.2μm) to ensure that the sealing surface is flat.
The outer ring type metal spiral wound gasket combines metal strength and non-metallic elasticity to provide reliable sealing under harsh working conditions. Its outer ring design further improves the installation accuracy and resistance to working condition fluctuations, making it the preferred solution for high temperature and high pressure flange connections. When selecting, it is necessary to comprehensively consider the media characteristics, flange type and operating conditions to ensure the best sealing effect and service life.
