Abstract:

In this study, the product standards of polyethylene pipes and reinforced polyethylene composite pipes in our country were analyzed and compared, the applicable ranges of pipe diameter, pressure, temperature and media under different implementation standards were enumerated. The advantages of polyethylene pipes and reinforced polyethylene composite pipes in the practical engineering application were introduced. The actual problems in the engineering practice were summarized into the following three aspects: (1) the problems caused by the performance of the material itself; (2) the problems caused by the implementation of product standards; (3) the problems resulting from the design and construction standards.

Key words: polyethylene pipe, reinforced polyethylene composite pipe, implementation standard
