High wear resistance: UHMWPE plastic pipe has a high ability of anti-sliding friction and the wear resistance is over 6 times than that of carbon steel with the same medium.
Corrosion resistance: based on the saturated molecular structure, UHMWPE has high chemical stability with the corrosion resistance of various corrosive media (acids, bases, salts) and organic solvents in a certain range of temperature and concentration.
High impact resistance: the impact resistance and impact absorbability of UHMWP Pipe rank first in plastic and it is hard to be cracked by either external strong impact or internal pressure fluctuations. The impact strength is 66 to 10 times of that of nylon and 4 times of PE100 polyethylene.
Superior tensile strength and pressure capacity: the tensile strength of UHMWPE pipe is 2 times of PE100, the environmental stress cracking resistance ability is 1 times of PE100. Therefore, the pressure capacity and resistance to environmental damage of UHMWPE pipe is far more than that of the general polyethylene pipe.
Weathering and aging resistance: UHMWPE pipe has good weather and aging resistance. Even used for 50 years or so the pipes can still maintain more than 70% of the mechanical properties because there are few unsaturated groups in UHMWPE molecular chains and the molecular weight is high.
Excellent energy saving: UHMWPE pipe is self-lubricating and non-adhesive with small frictional coefficient. The inner pipe wall produced with special technology is of corrosion, abrasion and scaling resistance, so the flow resistance is small.
Lightweight, easy connection and easy installation: per unit length of UHMWPE pip weighs only 1 / 8 of the same length of steel pipe, which gives advantage to loading and unloading, transportation, installation and use. Connection uses flange connection or hot melt welding.
Economy: the price of UHMWPE pipe is lower than that of traditional steel. Combined with low coefficient of friction, high flow capacity, high impact strength, corrosion resistance, wear resistance, weather resistance and many other factors its cost is far more than that of other plastic pipes and tubes.
Shandong Keli New Materials Co., Ltd. is located in National High-Tech Development Zone in Zibo of Shandong province, covering 100 acres, with 20 million registered capitals, mainly produces high molecular weight polyethylene products. The first processing capacity is 2700 tons per year and the second processing capacity is 5,400 tons per year with a total investment of about one billion Yuan. It was certificated by ISO9001 quality management system in 2010.
There are series of products in the company, four of which are patented products and some are designed first in the world reaching the world advanced level. The main products and features are:
Ultra-high molecular weight polyethylene pipe with diameter of 63-1100mm and the minimum wall thickness of 3mm ; Ultra-thin tube is national initiative;

High wear resistant impeller pump.
The unique company welding technology and equipments enable weld of ultra-high molecular weight polyethylene pipe, butt weld and vertical weld of plank, and weld of complex shaped products. The weld strength is equal to or greater than the material strength.
The company combines research and development, production and services together, forming a talent team led by the first-class experts of high molecular weight polyethylene processing, including 6 doctor professors and 3 senior engineers. Besides, there are more than 8 people with master degrees or above. It can provide users with detailed and thoughtful service: ① provide solutions according to their existent pipeline, pump, valve problems; ② providing special design of piping, pumps, valves according to their needs; ③ using a special formula (such as temperature, high wear, etc.) to produce pipeline, pumps and valves meeting the special requirements according to the their medium and working conditions.
The company is the holding company of Shandong Qilu Keli Chemical Institute Co., Ltd. which formerly was the technology industry of Sinopec institute of Qilu branch. In the implementation of “reform stream” in 2007, holding company of China Petroleum authorized Qilu Company to signed the “the agreement of technology and intellectual property use” with us and to cooperate in technology and product markets for long-term. It began to participate in high molecular weight polyethylene slurry synthesis technology development in 1997, achieving production capacity of 3,000 tons per year in 2004. The company is a National High-tech Enterprise, Shandong Academy Workstation, Shandong Province Joint Graduate Training Base, Zibo City Integrity Enterprise, Zibo City Innovation and Growing-up Industrial Enterprise, Zibo Excellent High-tech Industrial Enterprise in the top thirty, Zibo High-tech Zone Technology-based high-growth small medium enterprise.
Taking technical innovation as the driving force and processing technology development of ultra high molecular weight polyethylene as the core, in accordance with the development strategy of “standardization, specialization, complete, large-scale”, the company will focus on building itself the most advanced processing technology ultra-high molecular weight polyethylene research center and the largest domestic processing base of ultra-high molecular weight polyethylene.
