| titleOfInvention | A kind of sealing method of socket type interface |
| abstract | The invention relates to the field of pipe joint sealing, in particular to a method for sealing socket-type joints. Asbestos rope and KPI powder are mixed into potassium water glass, and then the annular gaps of socket-type joints are alternately filled respectively, and 40% sulfuric acid is used for sealing. Washing the external cement surface can prevent the socket-type pipeline from being corroded when conveying concentrated sulfuric acid, and at the same time, it can reduce the crack of the sealing material caused by the vibration of the device system itself, reduce the risk of environmental protection accidents, and save pipeline maintenance costs. |
