Winter Pipeline Maintenance Skills

Winter pipeline maintenance skills

1. Outdoor pipe maintenance

Drainage pipe line

Before the advent of winter, the outdoor drainage pipes should be thoroughly inspected. Check whether there are cracks and damage in the pipe, especially at the pipe interface. For minor cracks, special pipe sealant can be repaired; if badly damaged, the damaged pipe section shall be replaced in time.

Clean debris in the drainage pipe. Leaves, dirt and other debris may block pipes with ice in winter. A high-pressure water gun can be used to thoroughly remove the dirt and debris in the pipe to ensure smooth drainage.

In areas with low temperature, some insulation materials, such as hay, waste quilts, can be added to the inspection well of the drainage pipe to cover the exposed part of the pipeline to reduce heat loss and prevent the water in the pipeline from freezing.2. Water supply pipeline

The insulation treatment of water supply pipeline is the key to winter maintenance. The thermal insulation pipe sleeve can be used to wrap it outside the water supply pipe. The insulation pipe sleeve generally has rubber, plastic, polyurethane and other materials, with good insulation performance. When installing the insulation pipe sleeve, ensure that the interface is well sealed to avoid the entry of cold air.

Check the valve of the water supply pipeline. Ensure that the valve is in the normal working state, close without water leakage, and open smoothly. For valves exposed to the air, they can be wrapped with insulation cover to prevent freezing and cracking. If the valve fails, it should be repaired or replaced in time.

Pay attention to the weather forecast, before the extreme cold weather, you can properly empty part of the water in the water supply pipeline, to reduce the risk of pipe rupture due to water icing and expansion. In particular, some branch pipes that are not used for a long time can close the front valve and open the drainage outlet to drain the water.2. Indoor pipe maintenance

(1) Kitchen pipe

Winter kitchen water temperature is relatively high, easy to produce oil condensation. Use hot water and detergent to wash the kitchen sewer pipe regularly to reduce the attachment of oil pollution in the inner wall of the pipe. It can be deeply cleaned at least once a month, pour a lot of hot water into the pipe, then add the right amount of dishwashing liquid, wait for a while and then rinse with a lot of water.

Check for tight pipe connections under the kitchen sink. If loose or leaky, use the wrench to tighten the joint or replace the gasket. At the same time, attention should be paid to whether the drainage screen of the sink is normal to avoid large food residues entering the pipeline.

Keeping a certain temperature around the kitchen pipe can avoid blocking the pipe due to low temperature. If the kitchen temperature is low, you can install small electric heating equipment near the pipe, but pay attention to safety to prevent fire.2.toilet pipe

Toilet toilet, basin and other drainage pipes in winter should also pay attention to maintenance. To toilet, can use toilet cleaner to undertake clean regularly, can remove stain not only, still can prevent dirt accumulation to affect drainage. At the same time, to check whether the accessories of the toilet tank are normal, to avoid leakage caused by accessories failure, so that the ground and pipe around the water ice.

The sewer pipe of the wash basin is easily blocked by hair and debris. A hair filter can be installed at the drain port to clean up the hair on the filter regularly. For blocked pipes, you can use pipe dredging tools, such as hand spiral wire. If the blockage is serious, a professional pipeline dredging agent can be used, but it should be used correctly according to the instructions to avoid causing damage to the pipeline.

The floor drain in the bathroom is also prone to problems. To keep the floor drain smooth, to prevent bath water, hair and other blocked floor drain. The floor drain cover can be removed regularly for cleaning, and check whether the deodorant device of the floor drain is normal to avoid odor and cold air entering the room from the floor drain.3.Daily monitoring and emergency treatment of pipelines

2.Daily monitoring

1.Establish a pipeline inspection system, whether indoor or outdoor pipeline, should be inspected regularly. For the key parts prone to problems, such as the pipe elbow, interface, valves, etc., to increase the number of inspections. During the inspection, the condition of the pipeline can be judged by observing whether there is frost and water seepage on the surface of the pipeline, and checking whether there is water in the surrounding environment.

2.Install some simple monitoring equipment, such as temperature sensor, humidity sensor, etc. The temperature sensor can monitor the temperature around the pipe in real time and take thermal measures when the temperature is too low. The humidity sensor can detect whether the pipe has water leakage. Once the humidity rises abnormally, the water leakage point can be found in time.

(2) Emergency treatment

1.If the pipe is found to be frozen, do not rush to use boiling water to avoid the pipe breaking due to a sharp change in temperature. Pour it slowly with warm water to melt the ice gradually. For severe icing, the heating equipment such as electric hair dryer can be used to evenly heat the pipe evenly, but pay attention to keep a certain distance from the pipe to prevent damage to the pipe.

2.When the pipeline breaks and leaks, the first thing is to close the relevant valve, cut off the water source or drainage direction, and reduce the loss. Then quickly clean up the site water to prevent the spread of the ground to ice and slip. For the broken pipeline, it should be repaired or replaced in time. After the maintenance, the pipeline system should be checked to ensure that there are no other potential problems.

In short, the pipeline maintenance in winter requires us to make preparations in advance, strengthen daily monitoring, and deal with problems in time, so as to ensure the normal operation of the pipeline in the cold winter, and provide convenience for our life and production.
