1, Corrosion-resistant. Polyethylene is an inert content, except for a couple solid oxidant, can withstand a selection of chemical media erosion.n2, Devoid of leak. Polyethylene welded steel pipe mainly welded connection (incredibly hot soften link or fused link), guarantee that the interface materials, composition and administration body's personal identity in essence, to attain the integration of joint and pipe.nnTest verified that the tensile strength and burst strength of the interface was bigger than the pipe overall body, can effectively resist the tensile pressure in the force generated hoop strain and axial way.n3, Large toughness. Polyethylene coating steel pipe is a higher toughness of the pipe, which is normally a lot more than elongation at crack of 500%, dependent on the pipe's potential to adapt to uneven settlement is pretty solid. It is an superb seismic performance of the pipeline.nn4, With fantastic overall flexibility. Polyethylene versatile polyethylene tube can be coiled, and a longer length of the source does not need to have all types of connecting pipe opponent, and it is quick to procedure in accordance with the needs of the development adjustments, but also changes in the pre-development pipe shape, outdated tube inserted to restore the first measurement and proportions.nn5, With a very good potential to resist scratches. Research have shown, PE80 quality polyethylene pipe has superior resistance to SCG potential and scratch-resistant ability. PE100 polyethylene pipe elements are owning a much better capacity to resist scratches.nn6, Good resistance to quick crack pass. Polyethylene has great ability to transfer resistance to rapid crack. For the decreased the temperature, the increased the diameter and wall thickness, homepage the better functioning force, swift crack the plastic pipe the larger the hazard attributes.nnThe polyethylene pipe, in particular PE100 pipe a lot more ideal for huge diameter mild steel pipe. At present, the conventional polyethylene gas pipe overseas (IS04437-1997 and EN1555) has resistance to fast crack development (RCP) remaining bundled in the normal.nn7, Extended provider daily life. <=60  under the conditions can be used for more than 50 years.
