Lined with high molecular pipeline

Product introduction

Ultra-high molecular weight polyethylene pipe is made from ultra high molecular weight polyethylene pipe and steel pipe compounded by the science and technology. Is characterized by the flange of the steel pipe as strengthen the outer protective layer, apply by the ultra-high molecular weight polyethylene pipe as the substrate the lining of the tube, the inner base of ultra-high molecular weight polyethylene pipe tube along the outer tube extends to the outer flange end face and form a whole structure, the characteristics of the ultra-high molecular weight polyethylene tube and steel tube, formed has abrasion resistance, impact resistance, corrosion resistance, high pressure resistance, self-lubrication, impact absorption properties, anti caking pipeline equipment, widely used in the thermal power system of the fly ash conveyor, water pipe, tailings, mud conveying of mine industry, coal industry of coal pulverized coal high pressure conveying, coal-water slurry and high pressure conveying and other industries of mud, sludge conveying resistance to corrosion medium, etc.

Product features

1, the wear-resisting propertiesMolecular weight polyethylene pipe is as high as 2.5 million or more molecular weight of the high tube, small friction coefficient, so it has a very high ability of resistance to sliding friction. Wear 6 times higher than that of general steel alloy, stainless steel 29 times. 19 times that of phenolic resin, nylon 6 7 times, 5 times of polyethylene, greatly improves the service life of pipeline.

2, corrosion resistanceUhmw-pe is a saturated molecular structure, so its high chemical stability, the products can withstand strong chemical erosion, in addition to some acid at high temperature corrosion, slightly in other alkali, acid is not affected by corrosion.

3, high impact resistanceUltra-high molecular weight in the existing engineering plastic pipe has the highest impact toughness values, many materials in serious or repeated explosion shock stress fatigue crack, broken, broken, or surface. This product according to standard GB1843, cantilever beam impact experiments to achieve without damage, can bear strong impact force, internal overload and pressure fluctuations.

4, self lubricationDue to the ultra-high molecular weight polyethylene tube containing the waxy substance, and self lubrication is very good. Coefficient of friction (196 n, 2.5 hours) of only 0.217 MN/m (GB3960). Its sliding performance is superior to oil lubrication steel or brass. Especially in the harsh, dust, mud, its dry lubrication performance of this product more fully displayed. Exercise not only can freely, and to protect the relevant artifacts do not wear or strain.

5, low temperature resistanceUltra-high molecular weight polyethylene pipe excellent resistance to low temperature resistance, impact resistance, abrasion resistance at minus 269 degrees Celsius when basically remain unchanged. Is currently the only can work at near absolute zero temperature of a kind of engineering plastics. At the same time, due to wide, ultra-high molecular weight polyethylene pipe can be in for a long time – work under the temperature of 270 ??? to 270 ???.

6, is not easy to foulingUltra-high molecular weight polyethylene pipe with small friction coefficient and non-polarity, therefore has the very good surface adhesion, pipe roughness is high. Existing material in PH value for more than 9 medium scale, ultra-high molecular weight polyethylene pipe does not scale, this feature is significant for coal power stations for fly ash system. In crude oil, mud pipeline aspects also is very applicable.

7, long service life
