Before the inspection, these few things need to prepare polypropylene recycled pellet equipment

The inspection of polypropylene recycled pellet equipment is divided into external inspection, internal and external inspection and comprehensive inspection. How much do you know about the inspection of polypropylene recycled granules equipment? Do not even know what work needs to be done in advance for the inspection of polypropylene recycled granules equipment? It doesn’t matter if you don’t know, today Taicang Anticorrosive Equipment Company will introduce the inspection of polypropylene recycled granules equipment. Preparation related matters.

The pre-preparation for the inspection of polypropylene recycled granule equipment includes consulting relevant technical data to understand the defects found in the manufacture, installation and use of polypropylene recycled granule equipment. Then remove the internal medium of the storage tank, use blind plates to cut off the equipment and pipes connected to it, and have obvious cut off marks. The tank farm should be equipped with fire-fighting, safety and ambulance facilities. If hot work is required, hot fire approval procedures must be handled in accordance with regulations.

Before making preparations for the equipment inspection of polypropylene recycled granules, the residual gas in the storage tank shall be replaced and cleaned, and the sampling and analysis shall meet the safety standards. Open all manholes of the polypropylene recycled pellet equipment, remove the inner parts of the tank, and remove the dirt on the inner wall. It is also very important to cut off the power supply related to the storage tank. When entering the polypropylene regenerated granule equipment tank for inspection, a low-voltage explosion-proof lamp with a voltage not exceeding 12V or 24V should be used, and a special person must also be supervised outside the polypropylene regenerated granule equipment tank. When the power supply voltage of inspection instruments and repair tools exceeds 36V, a well-insulated flexible wire and a reliable grounding wire must be used. The technical status and use conditions of polypropylene recycled granule equipment are determined as appropriate in the first phase, but the external inspection is at least once a year, the internal and external inspections are at least once every 3 years, and the comprehensive inspection is at least once every 6 years. If the storage tank has been used for 15 years, internal and external inspections should be carried out every two years; if the storage tank has been used for 20 years, internal and external inspections should be carried out at least once a year. For storage tanks that have undergone regular inspections, the inspector shall submit an inspection report indicating whether the storage tank can continue to be used, or special monitoring and other measures are required.
