Sizing frame after pipeline forming

Abstract

The invention relates to a sizing frame after pipeline forming, and belongs to the technical field of brackets. The sizing frame comprises a frame bracket. The bracket is provided with a plurality ofheat exchanging rollers which rotate freely and are arranged in parallel front and back at equal intervals. The two ends of each heat exchanging roller are mounted on the frame bracket through bearings. Each heat exchanging roller is internally provided with an exchanging cavity. The right side of the frame bracket is provided with a water inlet pipe. The water inlet pipe is connected with the right end of each heat exchanging roller and communicates with the exchanging cavities. The left side of the frame bracket is provided with a water outlet pipe. The water outlet pipe is connected with the left end of each heat exchanging roller and communicates with the exchanging cavities. According to the sizing frame after pipeline forming, the structure is simple, the sizing time is shortened to2-3 hours, the size of the occupied space during pipeline sizing is effectively controlled, and the storage work after pipeline machining is facilitated.

Description

technical field [0001] The invention relates to a calibrating frame after a pipeline is formed, and belongs to the technical field of brackets. Background technique [0002] The existing corrosive liquid transportation pipeline is easily corroded during use, has a limited service life, and needs to be replaced frequently. At the same time, it is prone to deformation under the action of external force, has insufficient strength, and poor impact resistance. A lot of noise.

[0002] The existing corrosive liquid transportation pipeline is easily corroded during use, has a limited service life, and needs to be replaced frequently. At the same time, it is prone to deformation under the action of external force, has insufficient strength, and poor impact resistance. A lot of noise. The applicant applied for a patent on the same day on December 16, 2015. The invention application number is 201521052340.5, and the name is a pressure-resistant protective layer. This design solves the above problems, but during production, the pipe wall is very thick , is also very heavy, which brings great inconvenience to transportation and construction

[0003] For this reason, the application also designs a set of metal pipes with corrugated structure, but when forming, it takes a long time to naturally cool and shape in the afternoon in the traditional way. For example, a 12-meter long pipe has a diameter of 100mm, about It takes about 10 hours. Such a cooling rate is not conducive to the storage of pipeline processing, and its setting space occupies too much space, which is about 0.5 times more than before.
