The influence of elastic modulus of soft materials in Clamp Soft Connection on their performance

Influence on sealing performanceThe elastic modulus is directly related to the sealing performance of Clamp Soft Connection. When the elastic modulus of soft materials is moderate, the material can produce appropriate deformation under the tightening action of the clamp and fit closely to the surface of the connected pipe or equipment. For example, in the Clamp Soft Connection of gas transmission pipelines, if the elastic modulus is too low, the material will deform excessively when under pressure and may not be able to recover to its initial state, resulting in gaps in the seal and causing gas leakage. On the contrary, if the elastic modulus is too high, the material is difficult to be compressed and cannot effectively fill the small unevenness of the connection surface, which will also reduce the sealing effect.Influence on compensation abilityClamp Soft Connection needs to compensate for the axial and radial displacement of the pipeline. Soft materials with smaller elastic modulus have better flexibility and can produce larger deformation under smaller external forces, thereby better absorbing the axial stretching, compression and radial displacement of the pipeline. For example, in a pipeline system with thermal expansion and contraction, a soft connection material with a low elastic modulus can deform with the expansion and contraction of the pipeline, effectively avoiding the stress transfer caused by pipeline displacement and protecting the pipeline system. However, a too low elastic modulus may cause the soft connection to over-elongate or compress when under pressure, affecting its stability and service life.Impact on vibration absorption capacityThe elastic modulus of soft materials plays a key role in working conditions with vibration. Materials with lower elastic modulus can better buffer and absorb vibrations. For example, in some industrial pipelines with mechanical vibrations, soft connections can reduce the transmission of vibrations to other parts. Materials with high elastic modulus have poor vibration absorption effects, which may cause vibrations to propagate in the pipeline system and even cause resonance, damaging pipelines or connecting equipment.Impact on durabilityThe appropriate elastic modulus helps improve the durability of the Clamp Soft Connection. If the elastic modulus is not appropriate, the material is prone to fatigue, rupture and other problems under long-term pressure, vibration and displacement changes, affecting the overall life and reliability of the Clamp Soft Connection.
