发泡机设备:将发泡剂起发到钢管与防腐层之间从而起到产品使用中保温的作用。发泡机运行时将两个料罐中的物料通过比例计量泵压入发泡枪中,发泡枪中同时输送高压气流将混合料打入防腐层与钢管之间,变频调节比例计量泵的速度可以满足不同钢管所需发泡层的密度。 Foaming machine: the foaming agent is sent between the steel pipe and the anti-corrosion layer to play the role of heat preservation in the use of the product. During the operation of the foaming machine, the materials in the two material tanks are pressed into the foaming gun
