In recent years, the plastic pipe in the field of gas and water supply to application. Hose pipe clamp according to the China Plastics Processing Industry Association statistics, the national production capacity of over 3 million tons. Plastic pipe from the raw materials are divided into three main categories of PVC, PE and PP-R pipes.
PE piping systems with its high strength, high stiffness, durable, strong composite capacity and fracture resistance, ease of production and installation, low cost, occupy the market is relatively large sub-quota, and also on the rise. Particularly because of corrosion-resistant, flexible, reliable connection, highlight the advantages of gas transmission and distribution network (pressure 10MPa following long-distance high-pressure gas trunk pipelines) in the field, the world has been recognized PE pipeline system is the best option . Additionally, because non-toxic, smooth wall and a small resistance, long life, light weight, low labor intensity of installation, less the cost of construction, seismic performance, the material has good flexibility characteristics, PE piping systems more and more water supply enterprises. welcome to the pro-gaze of the municipal building, it has a good prospect and significant economic and social benefits.
Second, select the need for high-performance electrofusion
With the wide application of PE piping systems in the field of gas and water supply, the connection of PE pipe has become an unavoidable topic.On the one hand, a pressure pipe PE pipe due to gas and water supply, the quality of welding of pipe joints in the piping system occupies a pivotal position to improve the welding quality, improve the reliability of welding equipment in order to reduce the impact of human factors on the quality of welding has become the main way. Therefore, the degree of automation, welding equipment and welding stability is the main indicator of pipe fittings manufacturers and construction units to select high-performance welder.
The other hand, pipeline welding most of the field of construction, the harsh construction environment, the power grid fluctuations, these are the impact of pipeline welding quality welding equipment, which requires to have a wide supply function, able to adapt to different grid voltage, ensure that the output voltage stability, and has a lighter weight for easy field handling.
More mature PE pipe welding technology welding fusion welding and fused. Which are fused welding fused pipe molten weld, due to ease of handling, simple operation, welding speed, human factors is the effect of welding, can effectively improve the weld security advantages in practical applications has been strong development and promotion.
Therefore, be able to tell from the above analysis, the rapid development of the PE pipe clip will have also seen rapid growth and development of welding equipment, electrofusion in which is bound to play a very important role.
