A process method of replacing the heat tracing method of the jacket with the heat tracing method of the external heat tracing pipe

Abstract

The invention discloses a technique for replacing a jacket heat tracing method by means of a heat tracing manner of outer tracing pipes. The technique comprises four steps: 1, calculating the quantity of tracing pipes in an HTT-SUPERSEDE tracing system according to kinds of production technology requirements, local climate environment conditions, and tracing pipe diameter and tracing pipe quantity computational formulas in a petrochemical plant process pipe installation design handbook, and then checking and correcting the calculation result by ANYSYS finite element analysis simulation; 2, respectively carrying out corrosion prevention on a material pipe and the tracing pipes according to the chemical corrosion prevention requirements; 3, tamping heat-conducting cement along the tracing pipes and two sides of the material pipe, and smoothening along the tangential direction in pipeline tracing construction, and then fully filling the heat-conducting cement into a U-shaped groove, detaining on the outer tracing pipe, and tightening by a stainless steel wire; and 4, installing an insulation layer according to the design regulation after 24 hours after smearing the heat-conducting cement. The technique disclosed by the invention is simple and convenient, and the heat transfer effect is improved.

Description

technical field [0001] The invention relates to a process method of replacing the jacket heat tracing method with an external heat tracing pipe heat tracing method. The method utilizes an inorganic heat-conducting material (HTT-SD800 / 99LC ) is filled in the gap between the outer heat tracing pipe and the material pipe to enhance the heat tracing effect and replace the jacket heat tracing. The utility model belongs to the technical field of petroleum and chemical heat exchange. technical background [0002] In the petroleum, chemical, electric power, and national defense industries, the heat tracing and heat exchange equipment for pipeline transportation generally use tracing pipes, electric heat tracing pipes (belts) and sleeves, but most of the tracing pipes and electric heat tracing pipes (belts) rely on air convection and Radiation heat transfer, low heat transfer efficiency, large heat loss, using jacketed tubes, high heat transfer efficiency, low heat loss, but constru...

Problems solved by technology

[0003] At present, there are several heat-conducting cement products in China, but most of them are only selling heat-conducting cement. There is no specific product and heat tracing plan for a specific process. They just sell heat-conducting cement to users in a rough manner, and do not combine the characteristics and advantages of heat-conducting cement with the production process. play out
