Polypropylene is a thermoplastic belonging to the polyolefin group. Wuxi Yuda Plastic Welding Machinery provides welding equipment to handle all diameter sizes offered and has an extensive line of fusion machines available to buy for every application. Polypropylene pipe can be bent in the field, also polypropylene fabrication of plastics can be made like HDPE in workshops.
Polypropylene (PP) Pipe and Fittings assembly and joining of this system is performed by heat fusion. Fusion joints are made by heating and melting the pipe and fitting together. This type of joint gives a homogeneous transition between the two components without the lowering of chemical resistance associated with solvent cement joining and without the loss of integrity and loss of pressure handling ability of a threaded joint.
Five different fusion methods for Polypropylene Piping Systems are available and commonly used in today`s demanding applications. These include conventional socket fusion, electrofusion, conventional contact butt fusion.
For Polypropylene Pipe Fabrication, it can use Yuda Workshop Fitting Welding Machines and Plastic Pipe Saw. Polypropylene (PP) is a partly crystalline thermoplastic similar to HDPE. Both of them have same welding process but in different welding temperature. For more information for PP Fusion Welders, feel free to contact Wuxi Yuda Plastic Pipe Welding Machinery Factory

According to Yue Heng, director of the original Lanzhou Petroleum Machinery Research Institute, the newly established Gansu Lanke Petrochemical Hi-tech Equipment Co., Ltd. is a modern hi-tech enterprise with diversified state-owned holding rights. The registered capital of the company is 200 million yuan. It is expected to begin stock listing in January 2009. Xu Jian, president of China National Machinery Industry Corporation, stated that Gansu Lanke Petrochemical Hi-tech Equipment Co., Ltd. is a joint-stock company to be listed by the China National Machinery Industry Corporation. He hopes that Gansu Lanke can strive to get listed on the Shenzhen Stock Exchange of the China Securities Regulatory Commission as soon as possible.
The company's predecessor, the Lanzhou Petroleum Machinery Research Institute, is the industrial technology research institution of the national oil drilling machinery and oil refining and petrochemical equipment. It was established in May 1960. In the past 50 years since its establishment, Lanzhou Institute of Petroleum Machinery has contributed more than 990 scientific and technological achievements to the country, including 3 national invention awards, more than 160 provincial and ministerial scientific and technological progress awards, and 46 patents. It has developed the first direct-current electric drilling rig in China. For drilling equipment, the first set of 1 million tons/year refinery and the first 5 million tons/year oil refinery were optimized. At the same time, this institute also provided the first set of domestic oil-gas water separation equipment for China's offshore oil platforms.
The newly established Gansu Lanke Petrochemical High-tech Equipment Co., Ltd. is mainly engaged in oil drilling and mining machinery, oil refining and chemical equipment, offshore oil equipment and engineering, oil refining, chemical and natural gas processing and liquid recovery engineering and related engineering design and general contracting business. At present, the company has eight shareholders, namely: China National Machinery Industry Corporation, Ocean Petroleum Engineering Co., Ltd., China United Engineering Corporation, China National Engineering and Agricultural Machinery Import and Export Corporation, Zhejiang Xinda Group Co., Ltd., and Shanghai Development Investment Co., Ltd. Company, Panjin Huaxun Petroleum Complete Equipment Co., Ltd., China Pufa Machinery Industry Co., Ltd.
Lanzhou Institute of Petroleum Machinery is a core supplier of petrochemical equipment for PetroChina, Sinopec and CNOOC. On December 30, the institute was officially restructured and introduced strategic investors to become Gansu Lanke Petrochemical High-tech Equipment Co., Ltd.
