Hainan steel mesh skeleton pipe
With the rapid development of the construction market and the continuous improvement of rural road construction in recent years, the steel mesh skeleton pipe, with its own product advantages, has been widely used in various water pipes, water plant water supply, chemical sewage discharge, sea water transportation and other fields.
1. Before the construction of the steel mesh skeleton pipe, the pipe fittings must be inspected and signed, including the product quality, report, quantity, certificate and other product quality inspection conditions.
2. When the steel wire mesh skeleton pipe is transported and handled, it cannot be thrown, dragged, dropped, or placed together with sharp and chemicals. Metal products shall be used for binding.
3. The steel mesh skeleton pipes shall be stored in a cool and ventilated indoor environment, and the stacking height shall not exceed 1 m.
4. Before the welding of the steel wire mesh skeleton pipe, the pipe fittings shall be spot checked to eliminate the unqualified ones, and then the pressure parameters shall be debugged according to the site construction standards.
5. Before the steel wire of the pipe head of the wire mesh framework is closed, it shall be polished steadily and cut vertically to ensure that the width is polished evenly, the groove is cleaned, and the internal surface is scraped smoothly and evenly.
6. Before welding the steel wire mesh skeleton pipe, mark the insertion depth, and then strike the electric fusion joint gently to the mark to ensure that the two pipe sections are in the same line.
7. The steel wire mesh skeleton pipe shall not be subject to external force when cooling. After installation, there shall be no momentum or other hard objects in the backfill soil of the pipe, and no gaps shall be left during backfilling.
8. Before the pressure test of the steel mesh skeleton pipe, check that the backfill thickness is not less than 0.5m, and select a place with few people for pressure test, which is generally conducted 12 hours after welding.
