Headquartered in Shanghai, the largest industrial city in China, we have enjoyed years of steady growth in the industry. Our three main bases of operation are our R&D sales, service, and management base (the Shanghai Songjiang Headquarters), an equipment production base (the Shanghai Maogang Factory), and the pipe prefabrication base (the Jiangsu Huaian Factory). These three bases have allowed us
to expand as a company and further develop innovative solutions for our clients. Over the years, we have developed the first pipe prefabrication production line in China, the first pipe prefabrication fast fitting-up machine, the first pipe prefabrication service project, and the first on-site prefabrication service. Qianshan possesses more than one hundred proprietary technology and product patents, including patents on our pipe fabrication workstation, our pipe fabrication welding equipment, and our conveying equipment. Whether it is our trusted and dependable established equipment, or our new and innovative products, each piece is developed and produced with great effort and care.
