We have our own loading dock with a 500T capacity, and 22 cranes 3-35 tons. We have three spiral pipe welding facilities, and two sets of underground thermal insulation pipe manufacturing facilities. We have more than fifty technical personnel, among which, eight are senior technical personnel who have won six national invention patents, and ten new state of the art patents. The yearly production capacity is above five hundred million RMB. We are the largest production facility for specialized underground heating pipe, with the longest manufacturing history in East China. With the rapid growth of the Chinese economy and industrial development, especially in the Yangtze River Delta area, our company’s yearly production has been growing at a rapid pace; The sales of our products have expanded from the East China region to all of China. In order to achieve maximum energy savings, we have solved the pipe distortion problem by joining in research and development with “Tianjin University” and “Southeast University”, developing of a temperature tracking detection system using the “vacuum thermos technology”. Meanwhile, we are jointly involved in R&D with “Nanjing University Of Aeronautics and Astronautics”, in the technological development of surface treatment on metal infiltration double glow plasma and large diameter stainless steel spiral welded pipes. The secnet of our success: Advanced technology and prioritizing product development 1.Diameter 90- 1400(-20 - 120 )High density production and installation of polyethylene, polyurethane heat conserving underground pipe. 2.Diameter 32- 1020(150 - 350 )We are the first manufacturer in China to be producing and installing insulated underground steel piping and coupling. 3.We are the first domestic user for the newest imported anti-corrosion polyureathane elastomer coating technology. 4. All large diameter stainless steel pipes are spiral welded. 5. Double spiral-submerged arc welded pipes are available in diameters of 219- 920 ; 720- 3000; steel grade 80; large diameter spiral type pipes, low and middle pressure, fluid pipes, and pile pipes are 2.2m width. We use the most advanced manufacturing equipment and are constantly improving production methods 1、High density polyethylene pipes: SJ-90b, SJ-10B.
