Steel Wire Braided Metal Hose

The JIDONGDA Steel Wire Braided Metal Hose is specifically designed for demanding fluid and gas transport systems that require vibration resistance, the ability to accommodate misalignment, and durability under extreme temperature and pressure conditions. Unlike standard rubber hoses or rigid piping, this product combines the flexibility of a corrugated metal tube with the pressure resistance provided by a wire braid. This enables the resolution of common industrial issues such as installation difficulties, vibration-induced failure of rigid piping, and the short service life of traditional hoses.

The products fully comply with international standards, including GB/T 14525, ISO 10380, and EJMA. Thanks to refined manufacturing processes and a comprehensive quality control system, our products meet global industrial standards and are suitable for operation in the most challenging environments.

Product Design and Material Advantages

1. Inner Corrugated Layer

Constructed from corrugated tubing (material: stainless steel grades 304, 316, or 316L), this layer offers excellent corrosion resistance and performance stability at both high and low temperatures, while ensuring unobstructed flow of the medium without the risk of clogging. Its flexible corrugated structure accommodates displacements in various planes (axial, lateral, and angular), adapting to pipeline deformations without compromising transport efficiency.

2. Wire Braid Reinforcement Layer

Consists of a protective layer of single or double stainless steel wire braiding, which significantly enhances the hose's pressure resistance and structural integrity. The tight braid limits expansion of the inner hose under high pressure, protects against external mechanical impact, and dampens pipeline vibrations, thereby preventing hose damage and media leakage during prolonged operation.

Key Product Characteristics and Advantages

1. Exceptional Thermal Resistance: Operating temperature range from -196°C to +600°C; capable of reliably transporting specialized media (e.g., cryogenic LNG, high-temperature steam, hot oil) under extreme operating conditions.

2. High-Pressure Safety and Durability: Operating pressure range of 6 to 250 bar with a 3:1 burst safety factor; resistant to sudden pressure surges, eliminating the risk of pipeline rupture.

3. Effective Vibration Dampening and Equipment Protection: Absorbs continuous vibrations from pumps, compressors, and other equipment; reduces stress on the piping system; protects auxiliary equipment and extends the system's overall service life.

4. Automatic compensation for thermal expansion and contraction: Automatically compensates for displacements caused by temperature fluctuations, relieves pipeline stress, and prevents cracking or joint leakage.

5. Corrosion and aging resistance: Manufactured from stainless steel with pickling and passivation treatment; resistant to acids, alkalis, and salts, making the products suitable for use in the aggressive environments of the chemical and pharmaceutical industries.

6. Installation flexibility and custom ordering: Supports various industrial connection methods (flanged, threaded, welded, quick-connect); allows for the customization of hose length, number of braid layers, and assembly design to meet specific project requirements.

Rigorous Quality Control System

1. Simulated Service Condition Testing

Comprehensive tests (including internal pressure exposure, continuous vibration simulation, axial displacement, repeated flexing, and thermal expansion/contraction simulation) replicate real-world, long-term industrial operating conditions.

2. Key Control Parameters

Professional engineers monitor the stability of the corrugated section, braid integrity, weld quality, leak-tightness, and fitting attachment reliability at every stage of production, ensuring that no defective products reach the customer.

3. Specialized Dynamic Performance Testing

Impulse testing: Simulates pressure fluctuations and combined mechanical stresses to verify structural stability, fatigue strength, and durability.

Fitting strength testing: Tensile and load testing of welds and connection assemblies to ensure secure attachment, leak-tightness, and a high level of structural safety.

Key Application Areas

1. Energy Sector: Power generation equipment, steam transport systems, LNG equipment, and energy infrastructure projects.

2. Chemical Industry: Chemical production plants, transport of corrosive media (acids, alkalis), and chemical plant piping systems.

3. HVAC Systems: Heating, ventilation, and air conditioning equipment; industrial boilers; and building ventilation and heating systems.

4. Precision Manufacturing: Food processing, pharmaceutical manufacturing, and fluid transport in precision equipment.

5. Mechanical Equipment: Pump and compressor connections, hydraulic systems, and industrial equipment piping.

Industrial Application Examples

Example 1: Cooling system pipeline upgrade at a semiconductor manufacturing plant

A large semiconductor wafer manufacturing facility faced issues with the premature wear and cracking of standard PVC cooling hoses caused by high temperatures and equipment vibration. After replacing them with JIDONGDA DN85 304 stainless steel wire-braided metal hoses, the system could accommodate thermal expansion/contraction shifts of ±30 mm; the hoses effectively absorbed equipment vibration and completely resolved issues related to water leakage and material degradation. The equipment operated continuously for 27 months without leaks or structural damage, significantly enhancing production process stability.

Example 2: High-temperature steam transport project at a chemical plant

A chemical plant in Southeast China operated steam pipelines at 280°C that were subject to frequent thermal expansion and contraction cycles. Traditional rigid pipes were prone to stress cracking, while standard hoses lacked sufficient resistance to high temperatures and pressures. The project utilized custom-made JIDONGDA double-layer wire-braided metal hoses. Thanks to their high heat resistance and ability to compensate for displacement, the hoses operated leak-free for a year, substantially reducing maintenance frequency and lowering operating costs.
