In modern industry, sealing modules are key components to ensure the safe operation of equipment, prevent leakage and improve efficiency. They are widely used in many fields such as petroleum, chemical industry, shipbuilding, and electricity. With the development of technology, sealing modules not only need to meet the stringent requirements under high pressure, high temperature or corrosive environment, but also need to have the characteristics of high efficiency, environmental protection and long life. This article will introduce the application scenarios, product advantages, core characteristics and TST SEAL sealing module solutions of sealing modules in detail.

1. 1. What is a sealing module?

A sealing module is an integrated sealing system, usually composed of a flange body, a gasket, a bolt and possible auxiliary sealing structures, which is used to ensure that the connection between pipelines, valves, pumps or other equipment has good sealing performance. It achieves effective isolation of gas, liquid and even solid particles through the optimization of material selection, structural design and installation process.

1. 2. Industry application scenarios of TST SEAL sealing modules

1. 1. Oil and gas industry

In the process of oil and gas extraction, transportation and refining, sealing modules are widely used in high-pressure pipelines, wellhead devices, separators and compressor interfaces. Since the medium is often corrosive and the operating pressure is high (up to 100MPa or more), the pressure resistance and chemical corrosion resistance of the sealing system are extremely high.

1. 2. Chemical and pharmaceutical industries

Chemical production involves a large number of strong acids, strong alkalis and toxic and hazardous substances. The sealing module must have excellent chemical stability to prevent leakage from causing environmental pollution or safety accidents. At the same time, in the pharmaceutical industry with high cleanliness requirements, the sealing module must also meet GMP standards.

1. 3. Ship and marine engineering

Ship power systems, hydraulic transmission devices and liquefied natural gas (LNG) storage tanks all rely on high-quality sealing modules to cope with challenges such as deep sea pressure, low temperature (-162℃ LNG) and salt spray corrosion.

1. 4. Nuclear power and energy industry

The cooling system and turbine connection of nuclear power plants have extremely high requirements for the reliability of the sealing module. An all-metal sealing structure is required to ensure zero leakage and meet the ASME B16.5 Class 900 grade standard.

1. 5. Military and aerospace

Sealing modules used in extreme environments such as rocket fuel pipelines and aircraft hydraulic systems must have comprehensive properties such as lightweight, high and low temperature resistance (-200°C to +300°C) and vibration and shock resistance.

III. Core advantages of TST SEAL sealing modules

1. 1. Strong high-pressure tolerance

Advanced sealing modules can withstand pressures up to 100MPa and are suitable for extreme working conditions such as high-pressure gas wells and deep-water drilling platforms.

1. 2. Excellent corrosion resistance

Made of high-performance materials such as stainless steel, duplex steel, Hastelloy, etc., it can effectively resist corrosion from corrosive media such as hydrogen sulfide and chloride ions.

1. 3. Stable and reliable sealing effect

The precision-machined flange surface is combined with gaskets of special structure (such as corrugated gaskets, octagonal gaskets, and flexible graphite winding gaskets) to ensure long-term use without micro-leakage.

1. 4. Convenient installation and maintenance

The modular design supports quick replacement and installation. Some self-tightening sealing modules do not need to frequently adjust the bolt preload, greatly reducing operation and maintenance costs.

1. 5. Environmental protection and energy saving

The use of environmentally friendly materials such as new asbestos-free gaskets and low-VOC coatings complies with international environmental regulations (such as REACH, IMO 2020) and promotes green manufacturing.

1. 1. Analysis of product characteristics of TST SEAL sealing modules

1. 1. Material diversity

Depending on the different use environments, the sealing modules can be made of carbon steel, stainless steel (such as 304/316L), alloy steel (such as 2.25Cr-1Mo) or special alloys (such as Inconel 625, Hastelloy C-276) and other materials.

1. 2. Advanced structural design

Including but not limited to:

Concave and convex flange: Enhanced sealing contact area;

Trapezoidal groove flange: Suitable for metal octagonal gaskets, suitable for high-pressure occasions;

Self-tightening flange: Use internal pressure to automatically enhance the sealing effect;

Magnetic sealing module: Easy to quickly replace and improve maintenance efficiency.

1. 3. Intelligent monitoring function

Some high-end sealing modules integrate optical fiber sensors to monitor the sealing status in real time, warn of potential leakage risks in advance, and improve system safety.

1. 4. Digital management support

Combining digital twin technology and intelligent selection system, enterprises can automatically recommend the best sealing solution according to specific working parameters to improve procurement and maintenance efficiency.
