PE管主要运用在排水、输送、排污等行业,而PE管需要通过热熔焊机、对接机进行连接,杭州先创热熔设备厂主营全自动热熔对接焊机、全自动热熔焊机设备,焊接优先域有着超高的工艺。
在进行PE热熔焊接是,要注意温度控制要正确。PP-R热熔焊接温度为:253℃-274℃。如果温度低于253℃,管子和管件仅仅是薄薄的表面一层的熔化,一旦它们之间进行熔接,其熔接的强度就得不到保证,这就是我们通常所说的假焊现象;反之,如果温度高于274℃,管子和管件的表面分子遭到高温的破坏,使得PP-R形成稀薄的液体,连接后会使管子内径变小,更重要的是,连接部分会发生脆裂,尤其是在管路系统全部完工后进行通水加压,经常会发生此类问题。
而且恒温时间要长。恒温时间的长短是热熔焊接设备性能好坏的重要标志之一。热熔设备在升温至设定温度后仍有一个热量消耗的问题,特别是在冬季,风口处,即便是在非作业间隙,其热耗也是很大的,而一旦作业时,其管子和管件都在分别消耗热能,这就要求设备有很强的热能储存能力和及时补充能力。
PE pipe is mainly used in drainage, transportation, sewage and other industries, and PE pipe needs to be connected by hot melt welding machine, butt machine, Hangzhou first create hot melt equipment factory main automatic hot melt butt welding machine, automatic hot melt welding machine equipment, welding priority domain has super high technology.
PE hot melt welding is to pay attention to the correct temperature control. Pp-r hot melt welding temperature: 253℃-274℃. If the temperature is lower than 253℃, the pipe and pipe fittings are only a thin surface layer of melting, once they are welded, the strength of the welding can not be guaranteed, this is what we usually call false welding phenomenon; On the contrary, if the temperature is higher than 274℃, the surface molecules of the pipe and pipe fittings are damaged by high temperature, resulting in the formation of thin liquid PP-R, which will make the pipe diameter smaller after the connection. More importantly, the connection part will be brittle, especially after the completion of the pipeline system water pressure, this kind of problem often occurs.
And keep it constant for a long time. The length of constant temperature time is one of the important indicators of the performance of hot melt welding equipment. Hot melt equipment after heat setting temperature will still be a question of heat consumption, especially in the winter, FengKouChu, even in the working clearance, its heat loss is very big, once operations, the pipe and pipe fittings in the consumption of thermal energy, respectively, which requires the equipment has a strong heat storage capacity and the ability to replenish.
