A high-temperature large-diameter calibrated high-pipe support

Abstract

The invention relates to a high-temperature and large-diameter calibrated height pipe support, which is characterized in that: the two sides of the backing plate (2) are respectively welded to the high-temperature pipe (1) and the upper mounting seat (3); the backing plate (2) is connected to the The lower mounting base (4) frictionally slides over the center of the high-temperature pipeline to achieve high expansion and uniform radial expansion of the high-temperature pipeline (1); the upper mounting base (3) consists of two pieces, arranged symmetrically along the center of the high-temperature pipeline (1) , the base plate (9) of the upper mounting base (3) is a sliding surface, and the sliding direction of the base plate (9) is the ray direction at an angle of 45° to the center of the over-temperature pipeline (1). After the high-temperature pipeline (1) expands, the upper installation The seat (3) and the lower mounting seat (4) slide along the ray direction at an angle of 45° to the center of the high-temperature pipe (1). This device can improve the anti-instability and damage ability of high-temperature large-diameter pipelines, improve the stability and safety of this type of pipeline engineering, and reduce the difficulty and cost of manufacturing and installing supports.

Description

technical field [0001] The invention belongs to the field of pressure vessels and pressure pipelines, in particular to a high-temperature large-diameter pipeline support. Background technique [0002] At present, the industrial sliding support for large-diameter pipelines usually adopts the form of saddle-type sliding bearings. The structure of saddle-type sliding bearings is simple and low in cost. Gradient working conditions, the current saddle bearing standards cannot meet high temperature conditions, and stress concentration is prone to occur at the joint between the saddle bearing sliding bearing and the pipeline, and the pipeline expands and deforms radially under the action of high temperature, while Usually, the saddle support foundation is in a normal temperature state, and the expansion along the radial direction of the pipeline is small, which makes the expansion and deformation of the pipeline uneven, resulting in a diameter tolerance exceeding the standard, and ...
