Top 5 Concerns of European & American B2B Procurement Managers

Leak-Proof Reliability & Longevity

Procurement teams prioritize components with proven leak-proof performance to avoid operational disruptions. RunXing’s Flexible Single Sphere Rubber Joint with Flange features a seamless rubber-to-flange bonding process and reinforced structural design, achieving a 99.8% leak-free operation rate in 10-year field tests.
Material Compatibility with Media

Compatibility with corrosive chemicals, high-temperature steam, or petroleum hydrocarbons is non-negotiable. Our rubber joints are available in nitrile rubber (oil-resistant), silicone rubber (high-temperature), and EPDM (chemical-resistant) variants, tailored to specific industry needs.
Compliance with International Standards

Adherence to DIN, ANSI, and ISO standards ensures seamless integration with existing pipeline systems. All RunXing products meet ISO 9001:2015 quality management standards and pass pressure testing per ASME B16.5.
Installation & Maintenance Efficiency

Time-saving installation and easy maintenance reduce labor costs. Our flanged rubber joints are compatible with Dismantling Joint, enabling quick replacement without full pipeline shutdowns.
Supplier Capabilities & Customization

OEM/ODM flexibility and production capacity matter for large-scale projects. RunXing’s 50,000㎡ manufacturing facility houses 8 advanced production lines, supporting custom designs for specific pressure, temperature, and size requirements.

Leak-Proof Design & Core Functionalities

1. Structural Design for Leak Prevention

The Single Sphere Rubber Expansion Joint integrates three key components to eliminate leakage risks:

Rubber Body: Precision-molded from high-grade elastomers with uniform thickness, ensuring no weak points for fluid seepage.
Flange Connectors: Carbon steel or stainless steel flanges with CNC-machined sealing surfaces, compatible with Flange Adaptor for cross-standard integration.
Reinforcing Layer: Polyester fiber or steel wire braid embedded in the rubber body, enhancing structural integrity and resisting internal pressure surges.

2. Displacement Compensation

Industrial pipelines often experience axial, lateral, or angular displacement due to temperature changes or foundation movement. The single sphere design allows up to ±50mm axial movement, ±25mm lateral movement, and ±15° angular deflection—preventing stress cracks in welded joints. When paired with Bellow Expansion Joint, it forms a comprehensive displacement management system for long-distance pipelines.

3. Vibration Absorption

Pumps, compressors, and turbines generate vibrations that damage pipelines and equipment. The rubber joint’s elastic body acts as a shock absorber, dissipating up to 90% of vibrational energy. For extreme vibration environments, it can be combined with Flexible Metal Hose to create a dual-damping assembly, extending the service life of valves and meters by 30%.

4. Corrosion Resistance

Custom material selection ensures compatibility with harsh media: nitrile rubber for petroleum pipelines, silicone rubber for high-temperature steam lines, and EPDM for chemical processing. In seawater desalination plants, our silicone rubber joints work seamlessly with Duckbill Check Valve to resist saltwater corrosion and prevent backflow.

New Technology R&D & Application Developments

RunXing invests 8% of annual revenue in R&D, with a team of 25 engineers (including 5 PhDs in material science) dedicated to product innovation. Recent breakthroughs include:

Self-Healing Rubber Technology: A patented formulation that automatically seals minor punctures, reducing maintenance costs by 25% (Patent No.: US 11,542,367).
Low-Temperature Resistant Variant: Developed for Arctic oil pipelines, this rubber joint maintains flexibility at -50°C, outperforming industry standards by 15°C.
3D-Printed Custom Flanges: Enabling rapid prototyping of non-standard flange sizes, reducing lead time for OEM orders from 4 weeks to 7 days.

These innovations have been adopted by major industrial clients, including Shell (petroleum sector) and Siemens Energy (power generation), for their critical pipeline projects.

Industry Trend Analysis: The Future of Pipeline Flexible Components

1. Sustainability & Environmental Compliance

Stringent EU REACH and US EPA regulations are driving demand for eco-friendly rubber compounds with low VOC emissions. RunXing’s new bio-based rubber joints reduce carbon footprint by 30% while maintaining performance.

2. Miniaturization for Compact Systems

As industrial facilities become more space-efficient, there’s a growing need for compact flexible joints. Our slim-design single sphere rubber joint reduces installation space by 20% without compromising functionality.

3. Integration with Smart Pipeline Systems

The Industrial Internet of Things (IIoT) is transforming pipeline management. RunXing’s upcoming smart rubber joint will feature IoT sensors for real-time monitoring of pressure, temperature, and vibration, enabling remote diagnostics.

4. Rising Demand for Customization

With diverse industrial applications, procurement managers increasingly seek tailored solutions. RunXing’s 8 production lines and flexible manufacturing process can accommodate custom sizes (DN15-DN1200), pressure ratings (0.6-4.0MPa), and material combinations.

Product Usage & Maintenance Guide

Proper Installation Steps

Inspect the rubber joint and Flange Adaptor for damage or contamination before installation.
Align the joint with the pipeline flanges to avoid lateral stress during mounting.
Tighten bolts uniformly using a torque wrench (follow torque specifications per flange size).
Ensure the rubber body is not twisted or stretched beyond recommended limits.
Test the system with water pressure (1.5x working pressure) for 30 minutes to verify leak-proof performance.

Daily Maintenance Tips

Inspect the rubber joint monthly for cracks, bulges, or flange leakage.
Clean the joint surface regularly to remove corrosive residues or debris.
Replace the joint every 5-8 years (or sooner if used in extreme environments).
Use Dismantling Joint for easy removal during maintenance to avoid damaging the pipeline.
Avoid contact with sharp objects or excessive sunlight, which can degrade the rubber material.

All products undergo rigorous testing, including pressure testing, leakage testing, and fatigue testing, to ensure compliance with these standards. RunXing’s quality control team conducts 100% inspection before shipment.
