A socketed flexible interface steel pipe

Abstract

The utility model relates to a steel pipe technical field especially relates to a socket and spigot type flexible interface steel pipe. Including: base pipe, spigot steel ring, socket steel ring, spigot steel ring, socket steel ring sets up respectively at both ends of base pipe, spigot steel ring, socket steel ring is connected with base pipe, spigot steel ring, socket steel ring protrudes from base pipe outside, spigot steel ring and socket steel ring correspond, to make spigot steel ring and socket steel ring are inserted and connected. In prior art, it requires that operator has superb welding technology, and also needs specific operation environment and equipment support. In addition, welding operation can produce strong arc light and harmful gas, and workers must be equipped with professional protective equipment. Compared with prior art, through the setting of spigot steel ring and socket steel ring, two adjacent base pipes can be inserted together, so that welding is not needed when connecting two base pipes. Thus, the requirement for operation environment and equipment is simplified, and the workers will not be adversely affected by arc light and harmful gas.
