PE100-RC in large diameter sea outfall applications

 

Mark Yu, Dongyu Fang, Peck Tze Kang, Amos Tay , Fan Liu

Papers # 2018 Las-Vegas

Large diameter pipe was introduced in refineries and petrochemical plant, desalination plant and power plant for water intake and sea out fall in the past decade. PE100-RC material was selectedfor its excellent balance of superior bi-modal stress crack resistance and consistent high stiffness modulus.

Under the Chinese government’s “One Belt, One Road” initiative -a development strategy and framework to enhance economic cooperation and trade between China and countries around Asia, the Middle East, Africa and Europe, China’s largest PE spiral wound pipe convertor Fujian New Choice Pipe was awarded to produce sea outfall pipes for discharging cooling water for the Lanao Kauswagan power station in the Northern Mindanao region of the Philippines. Since the cooling water discharge was a very key safety feature for the power plant, the specification for the spiral wound pipes were determined to be a pipe diameter up to 2.8m with ring stiffness of SN8 and SN12.5. PE100-RC material was selected for the project due to its excellent balance of superior bi-modal stress crack resistance and consistent high stiffness modulus. In this paper, the authors describe material selection, the profile design, production trial, pipe jointing and on-site installation for the spiral wound pipe. It is shown that a 10% in material saving from the use of PE100-RC material as compared to standard PE material the company is using, with no change in the targeted ring stiffness. In addition to contributing to a significant reduction in overall production costs, the material savings also enable the finished product to be lighter and hence, easier to transport and install.
