2. Before the inspection and repair of steel pipelines, steel pipeline robots should be used to inspect steel pipelines to confirm the location and type of steel pipeline defects.
What should be paid attention to in the inspection and repair of steel pipelines?
1. The inspection and maintenance of steel pipelines need to block the steel pipelines with water, and then use high-pressure cleaning vehicles and silt suction vehicles to dredge and repair the steel pipelines. Rinse and pump water.
2. Ground non-excavation inspection of buried steel pipelines (including location and direction), buried depth, elevation, ground inspection, and corrosion environment inspection of buried steel pipelines.
3. When the steel pipeline enters the site, it should check the factory certificate and quality assurance, and check its category, model, appearance, specification, quantity should be appearance, size, radial stiffness, check the anti-seepage and anti-bending leakage after the load is applied. The inspection method should be carried out by relevant norms and standards.
4. After the inspection and treatment of the steel pipeline, clean the dirt on the surface of the equipment with clean water, wipe it with a clean towel, and put it back in place according to the packaging requirements; do not squeeze the equipment, collide or impact it, causing unnecessary damage.
