Qian Xiang Yu machinery by the groove pipe connection CNN system, provide a full set of technical support, combined with the actual situation in China, the Neiyinwailian, developed the vacuum casting and lost foam casting two international advanced casting engineering. The combination of the vacuum lost foam casting process and equipment to produce the groove type pipe fittings, the material is ductile iron QT450-10.
Groove pipe connection operation is very simple, no special professional skills, ordinary workers after a simple training to operate. This is because the number of products has been part of the technology with fine factory way to dissolve in the finished product. A fitting connection is only a few minutes, the maximum limit of the technical difficulty of the field operation, save time, thus also stable the project quality, improve the efficiency of work. This is also the general direction of the development of the installation technology.
The traditional welding and flange connection of the pipe connection, not only need to have the appropriate skills of welding workers, but also time-consuming, the operation of workers is difficult, and the existence of welding fume pollution. Due to the differences of operation space and welding skills, the welding quality and appearance are difficult to achieve satisfactory results, thus affecting the overall quality of the project.
Also because of the grooved pipe fittings for the finished part, the scene required operating space small, truly realized by a wall on angle installation, operation difficulty is greatly reduced, thus saving covers an area of, beautify the pipeline installation.
