Liaocheng Hongfu Pipe Industry Co., Ltd

Liaocheng Hongfu Pipe Industry Co., Ltd. is located in Liaocheng, Shandong Province, the largest seamless steel pipe distribution base in China and a scenic historic and cultural city (Jiangbei Water City). Its leading products include seamless steel pipes, centrifugal ductile iron pipes and fittings, and W-shaped flexible iron pipes and fittings for building drainage, Products such as pipe accessories and boiler accessories casting: nominal DN (100-2600) * wall thickness (6.5-28.3) length L6000mm water-cooled metal ductile iron pipes and fittings. The main components of water supply ductile iron pipes include carbon, silicon, manganese, sulfur, phosphorus, and magnesium. There is a certain amount of spherical graphite distributed on the matrix of ferrite and pearlite. Depending on the nominal diameter and requirements for elongation, the proportion of ferrite and pearlite in the matrix structure varies. The proportion of pearlite in small diameters is generally not more than 20%, while that in large diameters is generally controlled at around 25%. Minimum tensile strength: 420/MPa, minimum yield strength: 300/MPa, minimum elongation: 7%. Ductile iron pipes shall comply with the standard GB/T13295-2008 ISO2531-2008. The supporting pipe fittings are complete, which are widely used in water transmission, Oil pipeline, and production process pipe networks in food, pharmaceutical, chemical and other industries. Nominal DN (50-300) * wall thickness T (3.5-7.0) length L3000mm flexible cast iron pipes and pipe fittings, strictly comply with the requirements of GB12772-2008 Flexible Interface Cast Iron Pipes, Pipe Fittings and Accessories for Drainage, and adopt international advanced centrifugal casting production technology. The products have compact metal structure, high internal and external smoothness The advantages of thin and uniform walls,
