Cast basalt pipe integrates the wear resistance and corrosion resistance of cast basalt pipe, the toughness of steel pipe and the consolidation of cement mortar. Cast basalt pipe greatly improves the adaptability of products to various complex working conditions. Using cement mortar as filler can make the inner surface of steel pipe in alkaline medium, and produce purified film on the surface of steel pipe to prevent corrosion. It is wear-resistant, corrosion-resistant, high pressure resistant, safe and convenient transportation.
In order to reduce the loss of building materials, the use management should be standardized, such as:
Special warehouse for proper storage. Building materials shall be stored in a special material warehouse meeting the requirements, otherwise, the service life of materials will be reduced. For example, the steel shall be stored neatly and in batches according to the specification and model, and shall not be mixed. For outdoor storage, it shall be padded with sleepers, bricks or concrete, which shall be 10 ~ 30cm away from the ground.
For the distribution of materials, the principle of "first in, first out, pushing the old and storing the new" shall be implemented. The material consumption of the project department shall be combined with the accounting of divisional and subdivisional works, and the quota / Quota material requisition system shall be strictly implemented. Before construction, the project construction personnel must issue the quota material requisition, which must be filled in according to the column requirements without missing items. For valuables and large quantities, they can be distributed several times by small receipt according to the use situation. For articles that are easy to be damaged, the materialman shall conduct detailed inspection and handover during distribution, and both receiving and using parties shall sign on the certificate for approval.
