Recently, Sinopec (Tianjin) Petrochemical 260,000 tons/year polycarbonate project intermediate tank area effective heat tracing pipeline construction undertaken by the Fourth Construction Company of Refining and Chemical Engineering Group was rated as a "model project" by the owner
.
The total effective heat tracing pipeline construction in the intermediate tank area is 285 kilometers, using stainless steel pipes with a diameter of 12 mm, connected with cold simmering ferrules, with large spans, many valves, and irregular shapes, making cold simmering construction difficult
.
In order to efficiently advance the progress of the project, before the construction, the electrical and instrument professional project department of the Fourth Construction Company sent senior pipeline heating technicians and quality inspectors to the site, organized the operators to conduct a comprehensive technical quality disclosure and centralized training, and formulated according to the actual situation of the site.
During the construction process, the operators strictly control the quality of the working procedures, discover and correct on-site problems in time
.
In order to ensure the quality of heat tracing pipe laying, they made their own heat tracing coil tray turret, which not only improved the laying efficiency, but also avoided laying damage.
