Fushuo is one of the famous China Rubber Corrugated Compensator manufacturers and Rubber Corrugated Compensator suppliers. Our factory specializes in manufacturing of Silicone Soft Connection. The corrugated compensator is a compensating device used to absorb the dimensional changes of pipelines, conduits or containers caused by thermal expansion and cold contraction by utilizing the effective expansion and contraction of the elastic element of the corrugated compensator.
Relying on the elastic expansion characteristics of the bellows, the product can accurately absorb the size change of pipelines, conduits and containers caused by thermal expansion and contraction. It flexibly responds to axial, lateral and angular displacements, relieves system stress from the root, and avoids pipeline deformation or damage due to thermal expansion.
The unique structural design can effectively adjust axial, radial size errors and form and position tolerances generated during pipeline installation and manufacturing. During installation, butt calibration through the bellows ensures connection stability; after locking screws, it avoids pipeline damage caused by error accumulation, reducing construction difficulty and rework rate.
Silicone soft connections are made of high-quality silicone material, featuring outstanding flexibility and sealing performance. While inheriting the multi-directional displacement absorption advantage of corrugated compensators, they have excellent corrosion resistance and anti-aging properties, adapting to harsh working environments such as chemical media and water treatment systems.
The product can assist in protecting other pipe fittings, preventing bellows failure and extending the overall service life of the pipeline system. At the same time, the elastic rubber structure effectively absorbs vibration generated by equipment operation and reduces noise, improving the on-site working environment and ensuring stable operation of the whole system.

5. One-Stop Professional Service
Provide full-process support from product selection consultation, customized design, on-site installation guidance to post-maintenance and after-sales guarantee, ensuring customers purchase and use with confidence.
A1: Silicone soft connection is a type of rubber corrugated compensator with silicone as the core material, suitable for corrosion-resistant and medium-temperature scenarios. Ordinary rubber corrugated compensators use elastic rubber, focusing on cost-effectiveness and general working conditions. Both share multi-directional compensation functions, with material differences determining their application scope.
A2: They are mainly suitable for working conditions without high-temperature compensation requirements (temperature ≤200℃). Ideal for chemical industry, water treatment, ventilation and air conditioning, and general fluid transmission pipelines. For high-temperature scenarios, we can provide customized high-temperature resistant rubber types.
A3: Yes. We support full non-standard customization, including nominal diameter (DN50~1000mm+), working pressure (0.1~2.5MPa+), connection type (flange/thread), and material grade (food-grade/industrial-grade silicone), fully matching your pipeline system.
A4: Under normal working conditions and proper maintenance, the service life is 3~5 years. Silicone soft connections have better anti-aging performance, with service life up to 5~8 years in mild environments. The specific service life depends on temperature, medium and pressure.
A5: Yes. We provide professional installation guidance documents and on-site technical support. The after-sales service covers quality troubleshooting, maintenance advice and replacement support. We promise timely solutions for quality problems within the warranty period.
