Under the condition that the geological conditions of the steel wire mesh composite pipe are changed and the external force is forcibly destroyed, the water leakage of the pipe wall, the cracking of the pipe and the leakage of the joint may occur. How should this be the case? The steel wire mesh skeleton composite pipe manufacturer recommends that the repair method should be determined according to the degree of damage, location and damage of the pipe. The following details:
First, replacement of damaged pipes and fittings should be carried out in accordance with construction requirements.
Second, due to external damage caused by external settlement such as pipeline foundation settlement, temperature change, and external load changes, corresponding measures should be taken to eliminate various external factors after pipeline repair.
Pipeline maintenance method
First, when the pipe, pipe fitting, and hot-melt connection are leaking, the pipe should be cut off, and the pipe and wire mesh skeleton composite pipe fittings should be re-melted and hot-melted according to the construction requirements.
Second, the fused and hot-melt connected pipelines have a small damage range. The electric melting sleeve or the modified saddle-shaped fused-tube fitting repair method is used to cut the damaged portion of the pipe, and then the electric melting sleeve or the modified saddle-shaped electric The fuse tubes are connected.
Third, when the fused and hot-melt connected pipelines have a large damage range, the damaged pipe sections must be cut off and replaced with new ones. The joints can be fused, hot-melted or flanged, but the last welded joint must be used. The electrofusion sleeve is connected or flanged.
Fourth, when the steel mesh skeleton composite pipe is damaged by the flexible connection of the socket rubber ring, the damaged pipe segment can be cut off, replaced with a new pipe, and then connected by a double pipe clamp or an active sleeve (repair joint repairer).
Fifth, when the pipe whose nominal outer diameter is less than or equal to 63mm is damaged, the damaged pipe section can be cut off, the new pipe is replaced, and the wire mesh skeleton composite pipe is then connected by the repairer.
