Reinforced polyethylene pipe with super high molecular weight, manufacturing method and apparatus thereof

Abstract

The invention provides a reinforced ultra-high molecular weight polyethylene pipe and its manufacturing method and equipment. Its tensile strength is about 50Mpa, and the pipe wall thickness is 60-60% of the PE100 pipe wall thickness under the same pipe diameter and the same working pressure. 75%, which is 70-85% of the wall thickness of UHMWPE pipes. Provide a product with light weight, high strength, high wear resistance and high fatigue resistance for engineering plastic pipes under the premise of thin pipe wall and low manufacturing cost. The detection of the present invention proves: the tensile strength is about 50Mpa, and the impact strength is 130KJ / M 2 The wear resistance is about 4-7 times that of steel, 4 times that of nylon, and 3 times that of PE100. The resistance to environmental stress cracking is more than 4,000 hours, the fatigue resistance is about 800,000 times, and the low temperature resistance is at -40°C. The lower impact strength does not drop but reaches the highest value. The product cost of the invention is about 35% lower than that of PE100 pipes and ultra-high molecular weight polyethylene pipes, and the invention also has the advantages of safe and reliable production and use, and low engineering cost.

Description

technical field [0001] The invention relates to a pipe material, specifically a reinforced ultra-high molecular weight polyethylene pipe material and a manufacturing method and equipment thereof. Background technique [0002] At present, PE100 has the best comprehensive performance of polyethylene pipe widely used in various projects, its tensile strength is about 25Mpa, and its impact strength is about 20KJ / M 2 , the resistance to environmental stress cracking is about 2000 hours, etc. Because of its superior performance, it is widely used in various projects, but it still has some deficiencies in practical applications: high manufacturing cost, many main engineering technical indicators are still low, and safety and reliability are poor. In addition, the ultra-high molecular weight polyethylene pipe that entered the market in 2000 has many performance indicators superior to PE100, but because its tensile strength is slightly higher than PE100, and the price of raw materia...

Problems solved by technology

Due to its superior performance, it is widely used in various projects, but it still has some shortcomings in practical applications: high manufacturing cost, many major engineering technical indicators are still low, poor safety and reliability

In addition, the ultra-high molecular weight polyethylene pipes that entered the market in 2000 have many performance indicators that are superior to PE100, but because their tensile strength is slightly higher than that of PE100, the price of raw materials is higher, and the cost of pipes is higher than that of PE100, so the scope of application is limited.
