Performance Differences Between Polyethylene Tanks and Steel Lined Plastic Tanks

Steel lined plastic tank products are welded steel stamping steel cylinder body surface to polymer polyethylene (LLDPE) as raw materials, the use of special rotomolding process technology will be a whole polyethylene hot melt into the steel tank body surface. So that steel cans, nets (plastic shell), plastic (lined plastic layer) closely integrated in one to form a whole, this steel-plastic composite material with special chemical and physical properties, is taking steel, plastic combination of two different materials advantages Into a new composite anti-corrosion materials, with the strength of steel and polyethylene good corrosion resistance. 

Steel lined plastic tank products are generally composed of steel tanks, manholes, feed interface flange, discharge interface flange, temperature interface flange, intelligent instrument interface flange and level interface flange and other components, horizontal steel Lined plastic tanks usually have steel bearings. Steel liner plastic storage tank products of its arbitrary large, generally designed and manufactured according to customer requirements. The product of high temperature up to 100 degrees, the overall shape of polyethylene lined, no weld, the service life of up to 20 years. 

Steel liner plastic storage tank rigid strength, make up the polyethylene tank rigid strength and poor temperature shortcomings, tank shape and interface can be arbitrarily changed (the appropriate ratio of diameter and easy to transport). 

Polyethylene storage tank has the characteristics of internal and external corrosion can be used for all harsh corrosive environment and corrosive liquids. But the rigidity and temperature resistance than steel lined plastic tank, tank shape and interface position can not be arbitrarily changed (factory standard product mold fixed). 

Summary: Steel-lined plastic tanks have better corrosion resistance than polyethylene tanks and are more resistant to corrosion. High composite material strength, longer service life.
