Polyethylene pipe, also known as high-density polyethylene. Rotational: With this working method is generally a material is pulverized into a powder material to melt and flow during the thermal cycle. Rotational uses two types of PE: General and cross-linkable class. General Purpose MDPE / density polyethylene generally ranges from 0.935 to 0.945g / CC, with narrow MWD, the product has a high impact resistance and minimal warpage polyethylene pipe, having a melt index range is generally 3-8 . MI NA generally higher grade polyethylene pipe factory, because they do not have the desired impact rotomolding products and resistance to environmental stress cracking. Advantages of ultra high molecular weight polyethylene pipe: mobility. Ultra-high molecular weight polyethylene pipe has self-lubricating and non-adhesive high quality polyethylene pipe, the friction coefficient. The inner wall of the pipe technology, the special anti-corrosion, anti-abrasion, scaling, and therefore the flow resistance is small, long-term to maintain the flow rate and flow unabated. Therefore, the design of comparable steel pipe inner diameter is reduced by 15% -20%. High quality polyethylene pipe, Zhongbang plastics (certified), polyethylene pipe by plastics Ltd.
