Huaibei Mining Co., Ltd. is a major coal production enterprise in East China, with multiple operating mines. It has a large demand for mining pipes and a high procurement frequency. To ensure a continuous supply of production materials throughout the year, Huaibei Mining organized a public tender for the 2023 annual framework procurement of flanged steel pipes and flanged water injection pipes. Qingdao Haodeboer Industrial Co., Ltd. successfully won the bid for this project and became Huaibei Mining's annual framework supplier.
Flanged steel pipes and flanged water injection pipes. The pipe base is made of high-quality welded or seamless steel pipe, with pre-welded flanges at the pipe ends for easy and rapid connection and installation on-site. The pipes can be coated with anti-corrosion coatings or hot-dip galvanized as needed to enhance their corrosion resistance. The products comply with standards such as GB/T 3091 and GB/T 8163 and are suitable for underground water supply, injection, and drainage systems in coal mines.
