Treatment method for water leakage of SRTP pipe

Pipeline maintenance methods include electric fusion and hot-melt connection of pipes and fittings. When the interface leaks, the pipe should be cut off, and the pipes, SRTP pipe and fittings should be re-connected by electric fusion and hot-melt according to the construction requirements. For pipeline damage caused by external factors such as pipeline foundation settlement, temperature change, and external load change, corresponding measures should be taken to eliminate various external factors after the pipeline is repaired.

First, the replacement of damaged pipes and fittings should be carried out in accordance with the construction and laying requirements. When the pipe whose nominal outer diameter is less than or equal to 63 mm is damaged, the damaged pipe section can be cut off, replaced with a new pipe, and then connected with a repairer.

The steel mesh skeleton composite pipe is more and more widely used. The reason for the change of the geological conditions of the steel mesh skeleton composite pipe is that under the premise of forced damage by external force, water leakage on the pipe wall, pipe rupture and joint leakage, etc., should be determined according to the pipeline The damage degree, location and cause of damage determine the repair method. When the steel wire mesh skeleton composite pipe is flexibly connected with a socket rubber ring, if the pipe is damaged, the damaged pipe section can be cut off, replaced with a new pipe, and then connected with a double-bearing pipe collar or a flexible sleeve. When the damage range of the pipe connected by electric fusion or hot fusion is large, it is necessary to cut off the damaged pipe section and replace it with a new pipe. The joint can be connected by electric fusion, hot fusion or flange connection, but the last welding joint must use electric fusion sleeve Cylinder connection or flange connection. When the damage range of the pipe connected by electrofusion and hot fusion is very small, use the repair method of electric fusion sleeve or modified saddle-shaped electric fusion pipe fitting to cut off the damaged part of the pipe, and then use the electric fusion sleeve or modified saddle-shaped electric fusion pipe fitting to connect stand up.
