Key points of construction and installation:

1) The buried pipelines below the indoor floor should be re-excavated after the backfill of the civil engineering is tamped. Do not bury it before backfilling or on untamped soil.

2) The bottom of the buried pipeline trench should be flat, and there should be no protruding sharp objects. The particle size of the original soil should not be greater than 12mm, and a 100mm thick sand cushion can be laid if necessary. The backfill soil around the pipeline shall be filled up to 300mm above the top of the pipe, and the original soil can be backfilled after compaction. The buried depth of indoor buried pipelines should not be less than 300mm.

3) All pipe connection methods are required to be connected with pipes and pipes, pipes and fittings of the same brand and material, among which electric melting has a wider application range.
