Embodiment Construction
[0023] The present invention will be described in detail below through the accompanying drawings and examples. The examples given are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0024] The leak plugging and emergency rescue method for petrochemical special pipelines described in this embodiment is suitable for the petrochemical industry, with pressure and cold treatment plugging and physical leak plugging processes. The specific steps are as follows:
[0025] Step 1, use a leak stopper to plug leak point 2 on pipeline 1:
[0026] (1) Prepare a primary leak stopper. The primary leak stopper is composed of an oil-proof, acid-proof, high-pressure-resistant wedge-shaped sealing silicone ring 3 and a stainless steel wedge-shaped binding ring 4 with opposite shapes. Wrap the wedge-shaped sealing silicone ring 3 on the leak point 2 Near the pipeline, wrap the stainless steel we...
