Braided gaskets
The braided packing - also known as braided packing ring, braided cord, packing cord, water pump packing, valve packing and stuffing box packing - is an indispensable seal for dynamic applications such as pumps, valves and other rotating equipment used in industrial process plants.
The braided gasket is designed to seal between the shaft or spindle and the fixed pump housing or stuffing box to prevent leakage of liquids and gases.
Main types of braided gaskets
There are several types of braided gaskets, each with their unique properties, applications, advantages and disadvantages. Here are some of the most common ones:
Graphite
Braided packing with graphite yarn
These gaskets are known for their high temperature and pressure resistance. They are ideal for use in extreme environments where other gasket types can fail.
PTFE
Braided packing with PTFE yarn
PTFE, or polytetrafluoroethylene, is a material known for its chemical resistance. These gaskets are ideal for use in chemical processes where they can withstand aggressive media.
ARAMID
Braided packing with aramid fibers
Aramid is a strong and durable material that is ideal for use in high-pressure applications. These gaskets are known for their durability and long service life.
Where are braided gaskets used?
Braided gaskets are used in a wide range of industries and applications. Here are some of the most common ones:
Energy & utilities
In power plants, heating plants and other energy production and distribution facilities, braided gaskets are used to seal pipes and hatches (static application), valves and pumps (dynamic application) and other systems with liquids and gases under high pressure and high temperature.
Food industry
Braided gaskets, especially the PTFE type, are safe to use in food production as they are resistant to bacteria and other microorganisms.
Chemical industry
Due to their chemical resistance, braided gaskets are often used in chemical processing plants where they can withstand aggressive media.
Know the benefits and limitations of braided gaskets
Braided gaskets are a common seal type in many applications in industrial process plants, cargo pumps and screw conveyors. It is important to understand the different types, their applications, and their advantages and limitations.
Braided packing - benefits
- Temperature and pressure resistance
Braided gaskets can withstand extreme temperatures and pressures, making them ideal for use in demanding industrial environments. - Chemical resistance
Many types of braided gaskets are resistant to a wide range of chemicals, making them ideal for use in chemical processes. - Durability
Braided gaskets are known for their durability and long lifetime, which can reduce maintenance costs and downtime in many industrial processes.
Braided packing - limitations
- Installation
Braided gaskets require professional installation to ensure they work properly. This can increase the overall cost. - Price
Some types of braided gaskets, especially those made from specialty materials like PTFE or graphite, can be more expensive than simpler gasket types. - Not suitable for all applications
Although braided gaskets are very versatile, they are not suitable for all applications. For example, they are not always the best choice in highly corrosive environments or where there is significant abrasive wear (material degradation particles).
