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.

Abstract

This invention relates to method and apparatus for production of enhanced PVC pipes of super-high molecular weight. Their performance is as below: pull resistance of 50MPa or so, reduced wall thickness by 60 - 75% of PE100 pipe or 70 - 85% of PVC pipe of super-high molecular weight, impact resistance of 130KJ / M2, wear resistance as 4 - 7 times of steel, environmental stress resistance more than 4000 hours, fatigue resistance over 800,000 times, and highest impact resistance at -40deg.C. Costs on production are reduced by 35%, with easy installation and low cost on engineering.

Description

technical field [0001] The invention relates to a pipe, specifically a reinforced ultra-high molecular weight polyethylene pipe and its manufacturing method and equipment. Background technique [0002] At present, PE100 is the model with the best comprehensive performance of a large number of polyethylene pipes used in various projects, its tensile strength is about 25Mpa, and its impact strength is about 20KJ / M 2 , The ability to resist environmental stress cracking is about 2000 hours. 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, and 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 ...
