Stainless Steel Braided Metal Hose

Traditional rigid piping is susceptible to cracking, loose connections, and leaks caused by equipment vibration, multi-axis displacement, or thermal deformation. Combining flexibility, mechanical protection, and reliable sealing, JIDONGDA Stainless Steel Braided Metal Hoses serve as an excellent alternative to rigid piping. Their dual-layer protective structure—featuring an inner corrugated tube to accommodate deformation and an outer braid for enhanced protection—absorbs operational loads and compensates for pipeline displacement. These hoses maintain their seal integrity and performance stability over the long term, even under conditions of extreme temperatures and pressure fluctuations. They are widely used to connect fluid transport systems associated with rotating equipment (such as pumps, compressors, and generator sets) and are a key component of modern industrial hydraulic systems.

Key Product Advantages

1. Compensation for multi-plane displacements

Accommodates axial, lateral, and angular displacements; relieves pipeline stresses caused by equipment operation and thermal expansion/contraction, thereby preventing pipe ruptures and connection loosening.

2. Effective vibration damping and protection

Efficiently absorbs and isolates vibrations from rotating equipment (such as pumps and compressors), preventing transmission to adjacent components and piping, which significantly reduces equipment failure rates.

3. Ultra-wide temperature range

Withstands temperatures from -196°C to +450°C, meeting operational requirements for extreme conditions such as cryogenic fluid transport, high-temperature steam circulation, and the transfer of hot industrial media.

4. Excellent corrosion resistance

Manufactured from SS304 or SS316L stainless steel, ensuring resistance to oxidation, acids, alkalis, and abrasive wear; provides long-term stability in aggressive environments (e.g., marine and chemical industries) and guarantees an extended service life.

5. Compactness, flexibility, and ease of installation

Lightweight and pliable material allows for routing within confined or complex equipment spaces; this simplifies installation and reduces project timelines.

6. Customizable specifications and connection types

Supports various connection options, including BSP and NPT threads, ANSI/DIN flanges, quick-connect couplings, and weld ends; diameter, length, and braiding configuration (single or double layer) can be tailored to specific operating conditions.

Rigorous performance testing and quality control

1. Testing Standards

The Stainless Steel Braided Metal Hoses are manufactured and tested in strict accordance with industrial pipeline safety standards EN ISO 10380 and ASME B31.3; they meet international technical requirements regarding safety, flexibility, and vibration damping for industrial equipment.

2. Simulated Operating Conditions

Comprehensive tests are conducted covering both standard and extreme industrial operating conditions, including prolonged dynamic vibration loads, simulation of multi-directional displacements, cyclic pressure testing at 25 bar, and thermal cycling across a range of -196°C to +450°C.

3. Key Test Results

- Impulse Fatigue Test: Simulated operation exceeding 250,000 cycles; maintained stable flexibility and leak-tightness under prolonged vibration and pressure fluctuations, with no signs of degradation or failure.

- Connection Strength Test: Fittings successfully passed burst and mechanical load tests, ensuring connection reliability and a leak-free seal, which significantly reduces the need for future maintenance.

- Structural Stability Test: Following prolonged thermal cycling and vibration/shock testing, the braiding layer and corrugated inner tube retained their structural integrity without deformation or damage, demonstrating superior fatigue strength.

Practical Application Example

Case 1: Application in the hydraulic system of a continuous casting machine (CCM) at a metallurgical plant

A large domestic metallurgical enterprise originally used rigid copper piping in the hydraulic system of its continuous casting machine. Prolonged equipment vibration and frequent pipe flexing led to twisting and leaks, resulting in frequent maintenance shutdowns and high operating costs. After switching to JIDONGDA's Stainless Steel Braided Metal Hoses—capable of withstanding an operating pressure of 8 MPa with a minimum bending radius of just three times the pipe diameter—leakage and rupture issues were completely eliminated. The equipment failure rate dropped by 90%, and maintenance costs per unit were reduced by 40%, ensuring the continuous and stable operation of the hydraulic system.

Practical Application Example No. 2: Offshore platform piping project

A Southeast Asian engineering company specializing in offshore projects required piping to supply power and working fluids to an offshore platform. The piping needed to withstand harsh operating conditions, including salt spray corrosion, wind- and wave-induced vibrations, and temperature fluctuations. JIDONGDA supplied custom-designed hoses featuring SS316L corrosion-resistant stainless steel braiding and protective outer sheaths. After three years of continuous offshore operation, the hoses showed no signs of corrosion, leakage, or structural damage. They successfully withstood the aggressive marine environment, ensured the safe and stable operation of the platform's pipeline system, and enabled the client to significantly reduce equipment replacement and maintenance costs.

Key Application Areas

1. Industrial equipment: industrial pumps, compressors, generator sets, automated production lines

2. Energy sector: renewable energy equipment, thermal power systems, cryogenic fluid transport systems

3. Marine equipment: marine engines, ship piping systems, offshore platform auxiliary equipment

4. General industry: steam and HVAC systems, precision manufacturing equipment, chemical fluid transport systems
