In the complex environment of industrial production, the reliability of sealing technology is crucial. As an advanced sealing solution, Double Jacket Gasket is gradually gaining widespread attention. With its excellent performance, it provides efficient and safe sealing protection for many industrial fields.

1. What is Double Jacket Gasket?

Double Jacket Gasket is a gasket made of a soft and flexible core material, which is completely or partially wrapped by a metal jacket. The jacket material can be made of soft iron, low carbon steel, stainless steel, nickel, copper, aluminum, brass, titanium, monel alloy and other metals, while the core material is often made of expanded graphite, ceramic, polytetrafluoroethylene (PTFE), etc. Its structural design enables the gasket to maintain good sealing performance under different working conditions.

2. Working principle

The gasket achieves efficient sealing by applying strong pressure on the circular edge of the flange. When the two flanges are connected and tightened, the metal jacket of the gasket can effectively transmit pressure, ensure that the core material fits tightly on the sealing surface, fills the possible tiny gaps, and prevents the leakage of the medium. The metal jacket not only provides structural support, but also protects the core material from pressure, temperature fluctuations and corrosion. When faced with irregular or defective flange edges, it can withstand deviations of up to 30% of the initial thickness and still maintain a good sealing effect.

3. Application fields

(I) Heat exchangers

Heat exchangers are widely used in many industries such as chemical, power, and food, and need to operate in high temperature, high pressure and possibly corrosive media environments. Double Jacket Gasket is an ideal choice for heat exchanger sealing due to its excellent high temperature and high pressure resistance and corrosion resistance. It can ensure that fluids of different temperatures and pressures flow stably in their respective channels during the heat exchange process, avoiding reduced efficiency and safety hazards caused by leakage.

(II) Gas pipelines

In the process of gas transportation, it is crucial to ensure the sealing of the pipeline system. Any leakage may cause serious safety accidents. Double Jacket Gasket can effectively cope with pressure changes and medium characteristics in gas pipelines, provide reliable sealing, and ensure the safety and stability of gas transportation.

(III) Engine cylinder head

When the engine is running, the cylinder head is subjected to high temperature, high pressure and frequent mechanical vibration. Double Jacket Gasket, with its good elasticity and fatigue resistance, can maintain sealing under complex working conditions, prevent gas leakage, and ensure the normal operation and high efficiency of the engine.

(IV) Boilers and other pressure vessels

Boilers and pressure vessels are used to store and process high-pressure and high-temperature media in industrial production. The high strength, high sealing and tolerance to harsh environments of Double Jacket Gasket make it a key component for sealing these equipment and ensure the safe operation of the equipment.

4. Advantages and characteristics

(I) Excellent sealing performance

The perfect combination of metal jacket and core material gives Double Jacket Gasket excellent sealing ability. It can adapt to various complex working conditions, effectively prevent media leakage, and provide reliable sealing guarantee for industrial production.

(II) Good pressure resistance and temperature resistance

The metal jacket has high strength and can withstand high pressure. At the same time, the selected materials have good high temperature resistance, so that the gasket can still maintain stable performance in high temperature environment, and will not be deformed or damaged due to temperature changes.

(III) Strong corrosion resistance

According to different use environments, suitable metal jacket materials can be selected, such as stainless steel, titanium, etc. These materials have excellent corrosion resistance, can effectively resist the erosion of various corrosive media, and extend the service life of the gasket.

(IV) Adapt to irregular flanges

In actual applications, the flange surface may be irregular or defective. Double Jacket Gasket can withstand large thickness deviations, and through its own elastic deformation, it fits tightly on the irregular flange surface to achieve a good sealing effect. With the continuous advancement of industrial technology, the performance requirements for sealing products are also increasing. Double Jacket Gasket has shown a steady growth trend in market demand due to its outstanding performance in harsh environments such as high temperature, high pressure, and corrosion. Driven by the continuous development of industries such as chemical, energy, and automobiles, Double Jacket Gasket is expected to occupy a more important position in the future sealing market and provide more reliable guarantees for the safe and efficient operation of industrial production.

Double Jacket Gasket has shown great potential in the field of industrial sealing with its unique structural design and excellent performance advantages. With the continuous innovation of technology and the expansion of application fields, it will bring efficient and reliable sealing solutions to more industries and promote industrial production to a higher level.
