My country is one of the original parties to the Chemical Weapons Convention. In accordance with the relevant provisions of the "Convention", the International Organization for the Prohibition of Chemical Weapons began to initiate on-site verification of the State party in 1997. According to Yuan Longhua, deputy director of the National Office for Prohibition of Chemical Weapons, China has more than 1,500 companies involved in international verification, accounting for one third of the world total. Since 1998, China's related civil chemical companies have accepted a total of 61 international inspections and passed all. Since 2003, the number of civil chemical companies undergoing verification has gradually increased. It was 9 in 2003 and 10 in 2004. So far this year, 11 inspections have been accepted. Yuan Longhua said that according to the Convention, the chemical weapons possessed by the State Party will be completely destroyed in 15 years at most, and the "Convention" will be effective indefinitely. Therefore, the focus of performance verification in the future will be further transferred to the relevant civil chemical companies. Higher and higher.
The second “Contract on Compliance†organized by China Association of Monitoring and Controlled Chemicals carried out exchanges and discussions on how China’s civil chemical companies have been verified in recent years and how companies have responded to international verification in the course of their performance. Representatives of many companies such as Shanghai San Aifu New Material Co., Ltd., Jiangsu Meilan Chemical Group, Yantai Wanhua Synthetic Leather Group Co., Ltd., and Daqing Refining & Chemical Co., Ltd. Polymer No. 1 received high-performance and low-cost international reception. And how to interact with other departments of provinces and cities and do a good job of receiving international verification work was discussed.
What is saddle fusion? Saddle fusion (sidewall fuson) is, like butt fusion and socket fusion, another process based on hot plate welding. Saddle heat fusion differs from either socket, or butt fusion methods by performing fusion into the side of the pipe wall in a transverse orientation to the main pipe, rather than in line with the pipe. Hdpe saddle welding required workshop saddle fusion machines. This hdpe fusing process can be conducted while pressurized creating a [hot tap" when allowed by regulations and the pipeline owner. The pipe and saddle fitting surfaces are heated/fusing until they reach a proper temperature, the heating tool is removed and then the weld is formed. The process is complete following a cooling process. Always have a trained joining operator perform this procedure using properly maintained Pipe Fabrication Workshop Machines.
