A Safe and Efficient Steam Insulation Pipeline

Abstract

The invention provides a safe and efficient steam thermal insulation pipeline used for preventing damage of thermal insulation supports, and belongs to the technical field of conveying pipelines. According to the technical scheme, pipe clamps of each thermal insulation support are two semi-circular-arc-shaped plates, guard plates are welded to the two side faces of the pipe clamps respectively, riveting fixing parts are evenly welded to the inner side of each pipe clamp, and reinforcing ribs are connected between every two adjacent riveting fixing parts; and a rigid thermal insulation material is poured into a cavity between the inner walls of the pipe clamps and the outer wall of a working steel pipe, a support frame is installed between the outer walls of the pipe clamps and the inner wall of an outer protection steel pipe, and the support frame is a planar sliding frame or a guide sliding frame. According to the safe and efficient steam thermal insulation pipeline, the rigid thermal insulation material of the thermal insulation supports can play the role of thermal insulation, the riveting fixing parts and the reinforcing ribs can improve compressive strength of the rigid thermal insulation material, the working steel pipe, the pipe clamps of the thermal insulation supports and the guard plates play the roles of surrounding encircling and fixing to prevent sliding and disengaging of rigid thermal insulation material blocks, the support frame plays the role of stable supporting, and therefore operation of the steam pipeline is safer and more reliable and efficient.

Description

technical field [0001] The invention relates to a steel-sheathed steel steam insulation pipeline, which belongs to the technical field of transportation pipelines. Background technique [0002] In recent years, the steam pipeline network has made great progress and development. The diameter of steam pipelines has gradually increased, and the transmission distance has gradually increased. The research on the thermal insulation effect of steam pipelines is a current research hotspot. In order to reduce the heat loss of the steam pipe network, thermal insulation materials with small thermal conductivity are often used to increase the thermal insulation effect and reduce the heat loss of the pipe network. In terms of supports, heat insulating supports are used to reduce heat loss caused by thermal bridges. As an important part of the steam pipe network, the bracket plays the role of supporting and limiting the displacement of the pipeline. The pipeline needs to be placed every 3...

Problems solved by technology

However, cracking of the heat insulation layer often occurs during the operation of the above-mentioned pipelines, and the heat insulation layer has no shielding device along the axial direction of the pipeline. During the operation of the pipeline, due to the axial horizontal movement, the heat insulation block is subjected to reciprocating axial thrust , due to uneven force or excessive thrust, there is a risk of crack expansion, falling off, or even breaking away from the pipe clamp at the slight crack of the hard heat insulation material. The steam pipe network using this heat insulation bracket has potential safety hazards.
