Huaneng damping spring hangers pipe hangers custom pipeline equipment

Our support for the pipeline construction drawing budget work hangers, began the first of a five-year national economic development plan, and with the development of pipeline construction scale and maturing. Practice has proved that the pipe hanger construction drawing budget work, not only for investors to establish investment projects in the pipeline project to provide a reliable basis. And effectively promote the business activities of pipeline construction companies. In 1983, the State issued "on improving the pipeline construction pipe hangers Budget ten" (The State Planning Commission, the Planning Board pipeline construction gauge [File No. 1983 38 clearly stated) pipe hangers Construction , budget control and to determine cost of documents. After building pipe hangers and installation of construction drawing budget have been determined, it is to determine the budget cost of the pipeline project, signed a construction and installation contracts, implementation of the construction unit and construction unit investment responsibility and handle the engineering basis for settlement. The implementation of the tender project (pipeline hanger construction plans) budget is the construction price base price, thusly, pipe hangers Construction Budget work, become the pipeline construction work an essential part, in particular the implementation of today a market economy. Construction enterprises change their operational mechanism, more important practical significance pipe hangers construction drawing budget work. At this stage, the main role of the construction drawing budget are summarized as follows: Fixed pipeline project budget is an important basis for plumbing pipe hangers designed for specific files to determine pipe hangers installation project cost is the main content pipeline project contract price is of tenders or base price is based on the preparation of the tender project is to build a bank loan, the construction price allocation is based on the preparation of construction plans and construction design, engineering construction enterprise statistics are based on program management, engineering and economic accounting is based pipe support engineering completed a basis for settlement price Constant Spring pipe hangers (hereinafter referred to as the constant hanging) design and production of products based on the pipe hanger moment balance principle. Under load displacement plumbing permit, constant force spring hangers pipe load torque and a spring (or weight) moment always maintain a balance. Hanging with the constant support of the piping and equipment, in the event of displacement, it can provide constant support force, which will not bring additional stress to the plumbing. Generally used for displacement and stress the need to reduce plumbing places, such as power plant boiler, steam power plants, water, smoke, and combustion air duct and other suspension parts, and petroleum and chemical pipeline industry need to install such a constant force spring pipe hangers. When the pipe system thermal displacement is greater than a pipe hanging points 12mm, should choose to support the permanent lifting to avoid dangerous pipeline system bending stress and adverse stress transfer. Constant weight lifting lever according to the lever principle, with the balance weight and load balanced pipeline. Three-link spring-constant lifting can theoretically completely Constant, and four-link spring hanging straight theoretically pipeline approximately constant force spring hanger. Three-link, four-link according to Constant Spring Constant lifting torque balance principle, the use of appropriate link mechanism allows the spring side of the torque and load torque is equal to the load while maintaining constant or changes very little.
