Connecting structure of non-metallic pipe and metal plate

The invention discloses a connecting structure of a non-metallic pipe and a metal plate; and the connecting structure can realize connection between the non-metallic pipe and a hole in the metal plate by a connecting mode of a concave cavity and internal extrusion without needing chemical bonding, and is stable and reliable. The connecting structure is more suitable for connection of a fluorine-contained plastic pipe with high chemical stability and the metal plate, can be effectively applied to sealing connection between a heat exchange pipe of a heat exchanger and a metal pattern plate under the working conditions of high temperature and high corrosion, can save the cost, greatly improves the sealing strength, and prolongs the equipment service life. 本发明公开了种非金属管与金属板的连接结构，采用凹腔与内挤压的连接方式，无需化学粘结即可实现非金属管与金属板上开孔的连接，并且连接结构稳定，可靠。非常适合特别是化学稳定性高的含氟塑料管与金属板的连接。可有效应用于例如高温、高腐蚀工况下的换热器的换热管与金属花板之间的密封连接，不但能够节约成本，而且还极大的提高了密封强度，延长了设备的使用寿命。
