The present invention relates to a pipe connecting structure including synthetic resin lining in the inside thereof using an adapter. To be more particular, a pipe whose inside includes synthetic resin lining is connected with a counterpart pipe by inserting an adapter between the two pipes, and the adapter is installed at an area where abrasion is concentrated in order to prevent the abrasion in the pipe due to materials such as water and cinders of coal by sacrificing instead of the pipe. The worn out adapter can be replaced so that the life of the entire pipe can be extended. Pipes are connected in a flange type and a coupler type using the adapter so that the adapter can be connected to be used regardless of the combination type including the flange type and the coupler type, and a worker can selectively apply the connection of pipes according the installation environment. When connecting pipes using the adapter in the flange type, the adapter plays a role of a gasket in order to provide excellent airtightness. When connecting pipes using the adapter in the coupler type, the adapter plays a role of a rubber ring in order to provide excellent airtightness. By inserting metal in the center of the circumference of the adapter made of synthetic resin, the abrasion of the pipes can be reduced and the structural intensity can be improved. In addition, the pipe connecting structure including synthetic resin lining in the inside thereof using an adapter can apply to the connection of various pipes such as an industrial pipe, a water and sewage pipe, an oil pipeline, a drainpipe, a wastewater pipe, and a gas pipe. |
