Recently, China petroleum and chemical industry federation organizes the expert in Beijing's great hall of the people in taizhou "depending on the plastic Co., LTD. And changzhou university common development" high performance ultra high molecular weight polyethylene donghai bridge.it also enhance complex pipe and process equipment technology "project appraisal of scientific and technological achievements.
The Chinese academy of LiHeLin and from China petroleum planning institute, Chinese academy of sciences, Beijing university of chemical industry, chemical, tongji university and Harbin industrial university, China's oil group ShiYouGuan engineering institute of technology, daqing oil field design institute of experts listened to the work of the project report, technical reports and user representatives spoke, inspected the product samples, reviewed the appraisal material, after serious discussion, the experts agree: the project is a very good independent innovation achievements, and the overall technology has reached the international advanced level.
Taizhou "depending on the plastic Co., LTD. At home and abroad and the market demand, independent development of the screw solid phase transportation extrusion die head, the rapid increase of setting ultra-high molecular weight polyethylene pipe molding process technology and equipment, design the high strength steel wire spring small gaps two-way winding, polyolefin resin special adhesive glue of high temperature and high pressure, strengthening the structure, developed with ultra high molecular weight polyethylene pipe for tube, high strength spring steel wire to strengthen layer, modified high density polyethylene for layer, layer with special bonding between polyolefin resin, glue them into a new complex pipe. The preparation techniques and equipment technology with independent intellectual property rights, has been granted the national patent license 12, one invention patent 2 item.
Only a ChangSunYaoCan, deputy warden 'reading and fasteners and city, area, science and technology department responsible for in JianDingHui comrade.

Pipeline transportation is the railway, highway and water transport, air transport way after, developed as a new mode of transportation. Due to low investment, low energy consumption, transportation cost advantages, such as cheap, causing worldwide attention. Long-term since, pipe materials mainly use steel tube. High strength steel tube, easy welding, but more important, no corrosion resistance, don't wear resistance, easy and scaling, especially medium and environment on the corrosion of steel tube, bring pipeline failure and economic loss occur frequently. Plastic tubing corrosion resistance, has been partly replace steel tube, but low strength, not heat resistance, impact resistance, not easy ageing, also greatly limits the application of plastic pipe.
According to information, the market has been mainly used for plastic complex pipe buried, low pressure, water pipes. With the continuous development of pipeline transportation, solid, liquid and gas liquid mixing materials, including hydrogen sulfide corrosion media such as high viscosity crude oil of wax and transfer of material, the performance of the proposed pipeline for more special requirements. Market urgently need to both corrosion resistance and high pressure, high wear resistance and is down, the scale and resistance, low friction, good low temperature resistance of high performance specifications.
Ultra high molecular weight polyethylene donghai bridge.it also enhance complex pipe the best comprehensive properties, pressure can be as high as 10 MPa, bear the H2S, CO2, Cl-and acid, alkali, organic solvents and other medium corrosion, impact strength is five times the density polyethylene, wear-resisting ability is carbon steel 7 times, and resistance to fouling, low friction, good low temperature resistance. This product has set up a file in the petroleum, chemical, coal mine, mining, thermoelectric, waterway dredging, etc to be widely applied, show the unique advantages and very wide prospect of market.
