1, Corrosion-resistant. Polyethylene is an inert product, other than for a couple of powerful oxidant, can face up to a assortment of chemical media erosion.n2, Without having leak. Polyethylene welded metal pipe mainly welded relationship (hot melt link or fused connection), guarantee that the interface substance, composition and administration body's individual identification in essence, to accomplish the integration of joint and pipe.nTest verified that the tensile power and burst toughness of the interface was increased than the pipe entire body, can efficiently resist the tensile worry in the pressure created hoop anxiety and axial path.nn3, Superior toughness. Polyethylene coating steel pipe is a large toughness of the pipe, which is usually extra than elongation at break of five hundred%, centered on the pipe's potential to adapt to uneven settlement is extremely strong. It is an exceptional seismic general performance of the pipeline.nn4, With great flexibility. Polyethylene adaptable polyethylene tube can be coiled, and a for a longer period length of the offer does not have to have all sorts of connecting pipe opponent, and it is simple to procedure in accordance with the prerequisites of the construction variations, but also variations in the pre-development pipe condition, old tube inserted to restore the initial measurement and proportions.nn5, With a fantastic capability to resist scratches. Scientific studies have revealed, PE80 grade polyethylene pipe has greater resistance to SCG skill and scratch-resistant ability. PE100 polyethylene pipe components are having a superior capability to resist scratches.n6, Superior resistance to swift crack move. Polyethylene has fantastic ability to transfer resistance to rapid crack. For homepage the decrease the temperature, the higher the diameter and wall thickness, the higher operating strain, fast crack the plastic pipe the larger the threat properties.nnThe polyethylene pipe, in particular PE100 pipe extra appropriate for massive diameter mild steel pipe. At present, the common polyethylene fuel pipe overseas (IS04437-1997 and EN1555) has resistance to speedy crack progress (RCP) being included in the regular.n7, Long assistance life. <=60  under the conditions can be used for more than 50 years.
