Hongwo Braided Packing
Composition: Discontinuous aramid yarns;
PTFE impregation; Lubricant silicone free
The main advantages of aramid packings are their high strength and low weight. Like graphite, the aramid packings have slightly negative thermal expansion axial coefficient which means that the dimensions of aramid packings can be made thermally stable.
Like graphite, the aramid packings are resistant to impact and abrasion. Combined with other materials such as epoxy the aramid packings can be made waterproof.
Aramid fibres can be used as a composite which retains its flexibility with rubber. High tensile modulus and low breakage elongation along with very high chemical resistance make it the best alternative for difficult industrial applications.
The aramid packing compared with other kinds of braided packings can resist more severe media and higher pressure. It can be installed separately or as end rings with other kinds of packing to combine different characteristics into seals packing ring seal.
Aramid packing has a high degree of resiliency and consistency of volume and hence avoids frequent gland adjustments. Aramid Low thermal expansion characteri stics under actual operating conditions reduce mechanical pressure against shaft sleeves to minimize abrasion effect.

Advantages of Aramid Gland Packing:
1.High-Temperature Resistance:
One of the key advantages of aramid gland packing is its exceptional thermal resistance. Aramid fibers are capable of withstanding temperatures of up to 600°C, making them ideal for use in high-temperature applications. They are widely used in industries such as chemical processing, power generation, and petrochemicals.
2.Low Friction and Wear:
Aramid fibers are known for their low coefficient of friction, which reduces the wear and tear on the packing and shaft surfaces. This low friction also translates to reduced power consumption, making aramid gland packing a more energy-efficient option for industrial equipment.
3.Chemical Resistance:
Aramid gland packing has excellent chemical resistance, making it suitable for use in environments with aggressive chemicals and corrosive fluids. They can resist a wide range of chemicals, including acids, alkalis, solvents, and hydrocarbons.
Applications of Aramid Gland Packing:
1.Pumps and Compressors:
Aramid gland packing is widely used in pumps and compressors for sealing rotating shafts. They provide excellent sealing and prevent leakage of fluids and gases, even under high pressure and temperature conditions.
2.Valves and Flanges:
Aramid gland packing is also used in valves and flanges to prevent leakage and provide a tight seal. They can withstand
high-pressure applications and offer exceptional chemical resistance, making them ideal for use in chemical processing plants and refineries.

3.Steam Applications:
Aramid gland packing is commonly used in steam applications, where high temperatures and pressure are a concern. They provide reliable sealing and can withstand the harsh conditions of steam applications.
