The arrangement of PP pipes should be short and straight. In order to make full use of the water pressure in the outdoor pp pipe network, the water supply pipe should be located at the position of maximum water consumption or continuous water supply. The indoor water supply main should be close to the maximum water consumption, otherwise continuous water supply is not allowed. Guarantee production and safety: The location of the PP pipe shall not hinder the production operation, transportation and the use of the building. PP pipe shall not be placed on the water surface so as to incinerate, blast or damage materials, products and equipment, and shall be prevented from passing through production equipment. pp pipes shall not pass through shop windows, closets of civil buildings and wooden decorations. For workshops and buildings that do not allow water seepage, two sets of inlet pipes should be provided, and these inlet pipes should be connected indoors in a circular or penetrating two-way water supply mode.
