The four departments of the Ministry of Finance and the Ministry of Industry and Information released the news that, starting from April 1, this year, China will import a list of major equipment and equipment related to imports of equipment and products, catalogues of imported key spare parts and raw materials, and equipment and products that will not be tax-exempted for imports. And so on to be adjusted. This type of product includes three generations of nuclear power plants, second-generation modified nuclear power units, solar power generation equipment, and high-speed railway track construction companies that can enjoy tax exemption when they need to import equipment that meets the standards. The Ministry of Finance clarified the "National Catalog of Major Technical Equipment and Products Supported for Development" and "List of Imported Crucial Components and Raw Materials of Major Technical Equipment and Products" revised this year. It also stated that domestic enterprises meeting the specified conditions are required to produce new catalogues. The relevant parts, parts and raw materials of goods imported from the list of major technical equipment and products will be exempt from customs duties and import value-added tax. It is understood that since 2009, China has issued a "Notice on Adjusting the Taxation Policy for the Import of Major Technical Equipment." It said that since July 1, 2009, it has confirmed that domestic enterprises have produced major technical equipment and products that support the development of the country. The key parts and raw materials that must be imported must be exempted from import duties and import value-added tax. Pre-insulated Pipe Fabrication
Pre-insulated, pre-fabricated jacketed piping system is used for industrial and commercial applications. Pre-Insulated, pre-jacketed thermal pipe has a definite advantage over field installed insulation and jacketing. All straight sections of the factory preinsulated piping system shall be jacketed with a High Density Polyethylene (HDPE) jacket conforming to ASTM D1248,PVC jackets shall not be allowed.
All field butt joints shall be made in straight sections of pipe.here for welding polyethylene, it can use field hdpe pipe Butt Fusion Machines according to pipe range. For PE Pre-insulated pipe fabrication, It will use workshop fitting machines for bend fabrication of plastics. How it works? Firstly you need to prepare pe pipe Angle Cutting Saw and fix thin pipe on sepcial clamp, and then cut hdpe pre-insulated pipe in required angle. Then move this pipe and fix them on elbow clamps of pre-insulated fitting welding equipment. Special half heating plates positioned on top of the welding zone are used to ensure the required welding temperature, The appication of uniform welding pressure which is controlled hydraulically, ensures the quality of the weld between the sleeve and the pipe casing. The welding phases of pipe fabrication are below: 1. Approaching and preheating 2: Heating 3.Removing the heating element 4. Reaching the welding pressure 5.Welding 6. Cooling
