Pipe materials should consider the resistance to high (low) temperature and high corrosion. 
The development trend of pipe specifications is large diameter and thick wall.
China is a country with more coal and less oil, and the coal is China's most important energy source. High sulfur, chlorine, hydrogen and other elements and water soluble substances are common in coal chemical industry system, which have high corrosion properties to metal materials. According to various corrosion conditions of coal chemical industry, Jiuli's engineers have researched and developed various kinds of high-grade stainless steel and alloy pipe manufacturing processes based on the properties of the materials themselves, so that the pipes can be successfully and stably applied in various fields of coal chemical industry.
