Bio-Soluble Fiber Gland Packing (Braided Rope)

 

Beijing Feprefo Engineering Technology Co., Ltd. - Detailed Overview of Bio-Soluble Fiber GlandPacking (Braided Rope) Product

In the field of industrial sealing, balancing high performance with environmental protection has always been a core objective for companies. Beijing Feprefo Engineering Technology Co., Ltd., with years of deep expertise in the fireproof, thermal insulation, and sealing industry, has launched its Bio-Soluble Fiber Gland Packing (Braided Rope). Through continuous R&D in material technology and a precise understanding of market needs, this product offers excellent high-temperature resistance and corrosion resistance, while its outstanding environmental characteristics align with the global trend towards green industry. It has become a preferred sealing product for equipment in sectors such as chemical, metallurgy, and energy.

I. Basic Product Information: Aliases, Shapes, and Core Material

(A) Product Aliases and Naming Logic

This product is commonly referred to in industrial applications as Bio-Soluble Fiber Braided Rope. The alias "Braided Rope" originates from its core manufacturing process – it is made from high-strength bio-soluble fibers through spinning and weaving (braiding). This intuitively reflects the product's structural characteristics and helps industry professionals quickly understand its processing method and morphological features.

(B) Multi-Shape Design for Diverse Sealing Scenarios

To meet the structural requirements of different equipment sealing chambers, the product is available in three mainstream cross-sectional shapes, allowing flexible selection based on the seal groove dimensions of valves, pumps, furnace doors, etc.:

Round: Suitable for round seal grooves with high conformity, especially ideal for dynamic sealing in rotating shaft equipment.

Square: Provides uniform contact area and strong sealing stability, commonly used for static flanges and valve stem sealing.

Rectangular: Can be customized according to groove depth and width, adaptable for non-standard sealing spaces, offering wider compatibility.

(C) Core Material: High-Strength Bio-Soluble Fiber

The product uses high-strength bio-soluble fiber as its base material. Unlike traditional non-degradable refractory fibers, this material ensures structural strength while possessing inherent environmental attributes. This lays the foundation for the subsequent "biodegradable" characteristic and "compliance with EU REACH regulations," also allowing the product to reduce long-term environmental burden after disposal.

II. Reinforcement Materials: Glass Filament and Multi-Metal Wires, Enabling Performance Enhancement

To address different temperature, pressure, and media conditions, the product's structural strength and durability can be enhanced through added reinforcement materials, specifically divided into two categories:

(A) Glass Filament Reinforcement: Cost-Effective Choice for Medium-Low Temperature Conditions

For conventional medium-low temperature sealing scenarios (e.g., ventilation ducts below 800°C, ordinary ovens), adding glass filament as reinforcement enhances the packing's tensile strength and abrasion resistance, preventing breakage or deformation during installation or use, while effectively controlling production costs to meet the sealing needs of general industrial equipment.

(B) Metal Wire Reinforcement: Professional Solution for High-Temperature, High-Pressure, and Strong Corrosion Scenarios

For harsh conditions involving high temperature, high pressure, or strong corrosion, the product offers various metal wire reinforcement options to cover performance needs across different scenarios:

304 Stainless Steel Wire: Combines corrosion resistance with cost-effectiveness, suitable for moderately corrosive environments (e.g., weak acid/alkali solutions, steam); the most widely used reinforcement material in the industrial field.

310 Stainless Steel Wire: Offers superior high-temperature resistance, capable of long-term stable operation in high-temperature environments above 1000°C, suitable for sealing in high-temperature equipment like metallurgical furnaces and kilns.

316 Stainless Steel Wire: Performs exceptionally well in strongly corrosive media (e.g., seawater, chemical solvents), applicable in marine engineering, chemical reactors, etc.

Nichrome Wire (Ni-Cr Wire): High oxidation resistance, resistant to aging in high-temperature oxidizing atmospheres (e.g., heating furnaces, incineration equipment), extending the service life of sealing components.

Copper Wire: Possesses good thermal conductivity and ductility, adaptable for sealing scenarios requiring thermal conductivity efficiency, while also improving the packing's flexibility.

III. Key Performance: 1260°C Heat Resistance + Dual Environmental Guarantees

(A) Temperature Resistance: Core Advantage for High-Temperature Applications

Leveraging the properties of the high-strength bio-soluble fiber raw material and the synergistic effect of reinforcement materials, the product's temperature resistance reaches a high level in the field of industrial sealing:

Continuous Use Temperature: 1050°C, meeting the long-term sealing needs of most industrial high-temperature equipment (e.g., tunnel kilns, steam pipelines, gas turbine generator sets).

Short-Term Use Temperature: Up to 1260°C maximum; maintains structural stability during special operating conditions like equipment start-stop or short-term overtemperature, preventing safety hazards caused by seal failure.

Simultaneously, the product inherits the corrosion resistance of bio-soluble fibers, effectively resisting erosion from acid/alkali solutions and wash from molten metals like aluminum and zinc, maintaining reliable performance even in highly corrosive environments such as metallurgy and chemical industries.

(B) Environmental Performance: Aligning with Global Green Development Standards

As a representative product of Beijing Feprefo's commitment to the "Green Industry" philosophy, the environmental performance of this packing is mainly reflected in two dimensions:

Compliance with EU REACH Regulations: Strictly adheres to the EU Regulation on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH). No harmful chemicals like lead, mercury, or PAHs are added during raw material selection or production. This not only ensures the health and safety of operators but also allows the product to meet requirements for export to the EU and other regions with high environmental standards, breaking through environmental barriers in international trade.

Biodegradable Characteristic: Unlike traditional refractory fiber packing, which becomes non-degradable solid waste after disposal, this product can be gradually degraded by microorganisms in the natural environment after disposal. This reduces industrial solid waste treatment costs and environmental pollution, aligning with "Carbon Neutrality" and sustainable development trends. It is particularly suitable for industries with stringent requirements for environmental protection and cleanliness, such as food and pharmaceuticals.

IV. Corporate Assurance: Dual Support of Quality and Service

Beijing Feprefo Engineering Technology Co., Ltd. consistently adheres to the philosophy "Fire protection is a matter of conscience, thermal insulation is a virtuous deed," providing comprehensive quality assurance for its Bio-Soluble Fiber Gland Packing (Braided Rope) throughout the entire process:
