PE pipe market
From 2018 to 2019 , the economic environment has declined, leading to unstable economies in many industries, which not only involves traditional industries, but also industrial manufacturing industries such as PE pipes are affected to some extent, but high-quality PE Pipe producers have strong profit models and competitive advantages, so they have the ability to weather difficult times in the face of accidental difficulties.
Nowadays, many places in China are vigorously promoting the use of PE pipes, so in order to meet the needs of the market, domestic PE pipe manufacturers are also countless. However, with the continuous development of the economy, PE pipes are widely used, of which water supply pipes and irrigation pipes are their two major application markets. However, there is insufficient demand in the international market, domestic production costs and prices have risen, and China's pipeline enterprises are facing operational crisis. In order to get rid of the operating difficulties of PE pipelines, industry insiders pointed out that pipeline companies should accelerate the pace of transformation and upgrading, develop professional consultants, and promote the orderly development of the pipeline industry.
The unique flexibility of PE pipes also allows them to effectively resist underground movements and end loads. On the surface, plastic buried pipes are inferior to cement pipes and metal pipes in terms of strength and rigidity. However, from the perspective of practical applications, plastic buried pipes are " flexible pipes " . When properly designed and laid, plastic buried pipes are It bears the load with the surrounding soil.
同时，聚乙烯的压力松弛特性可有效地通过形变而消耗应力，其实际轴向应力水平远比理论计算值低，而且其断裂伸长率一般都大于 500% ，弯曲半径可以小到管直径的 20~25 倍，是一种高韧性材料，对地基不均匀沉降的适应能力非常强，这些特点使其成为抵御地震、地基沉降以及温差伸缩的优秀的管道。 Therefore, plastic buried pipes do not need to have the same strength and rigidity as " steel pipes " to meet the mechanical properties in buried use. At the same time, the pressure relaxation characteristics of polyethylene can effectively consume stress through deformation, and its actual axial stress level It is much lower than the theoretical calculation value, and its elongation at break is generally greater than 500% . The bending radius can be as small as 20 to 25 times the pipe diameter . It is a highly ductile material and has a strong ability to adapt to uneven settlement of the foundation. These characteristics make it an excellent pipeline to resist earthquakes, foundation settlement, and expansion and contraction of temperature differences. For example, during the 1995 Kobe earthquake in Japan, PE water pipes and gas pipes were spared. Requirements.
