Manufacturing Technology for Drawn Tee Combined-welding TypeGas-collecting Pipe

Described in the paper are the structures and present application situations of the gas-collecting pipes as made at home and abroad.Also analyzed are the main aspects of the drawn Tee combined-welding type gas-collecting pipe, including manufacturing process, wall thickness, the design of combined welding, and the advantages of the process and the product performance.It is regarded via the analysis that there are just small difficulties as encountered with manufacturing and processing the components of the said gas collecting-pipe such as the drawn Tee, the cylinder and the pipe cap, etc.And moreover the drawn Tee and the pipe cap can be made as standard parts.The drawn Tee combinedwelding type gas-collecting pipe has high pressure-bearing capacity to meet the demand for pipeline development, and beyond any restriction of its material and diameter size.The application range of the said pipe can be extended.Moreover the pipe is in possession of such advantages as low manufacture costs, and consistent and reliable quality performance.
