Description

High strength antidetonation protective sheath Technical Field The utility model relates to the technical field of energy pipeline anti-seismic protection sleeves, in particular to a high-strength anti-seismic protection sleeve. Background The energy pipeline is widely applied in the energy industries such as petroleum, natural gas, thermal power transmission and the like, and the high-strength anti-seismic protection sleeve of the energy pipeline is an important facility for guaranteeing energy transmission safety. The composite material is made of a high-strength and high-toughness composite material, is combined with a special buffering energy-absorbing structure design, can effectively disperse stress, absorb energy and reduce displacement and deformation of a pipeline caused by vibration under severe vibration such as earthquake, has excellent corrosion resistance and weather resistance, prolongs the service life of the pipeline, and is a firm safety defense line for stable transportation of petroleum, natural gas and other energy sources. Traditional pipeline safeguard measure antidetonation mechanism is single, relies on rubber or spring more, is difficult to handle complicated vibration, and structural stability and suitability are poor, and easy not hard up aversion, unable self-adaptation pipeline changes, and safeguard function is limited, and outer material is difficult to compromise shock resistance and corrosion-resistant, and lacks the heat dissipation design, and under strong vibration effect, the pipeline appears interface easily and becomes flexible, pipeline warp even rupture scheduling problem, and then leads to the energy to leak, causes the incident, for this reason, we propose a high strength antidetonation protective sheath.
