In the past few days, Sinochem Quanzhou 1 million tons/year ethylene project undertaken by the Tenth Construction Company of Refining and Chemical Engineering has been fully promoting the construction of process pipelines, creating favorable conditions for the realization of high-standard CCCC in the ethylene plant by the end of 201
It is understood that the welding construction volume of Sinochem Quanzhou's 1 million tons/year ethylene plant process pipeline is as high as 1 million inches in diameter, and it is faced with many factors such as complex types of pipeline materials and strict welding process requiremen.
In order to control the welding quality of process pipelines, the project department starts from the entry of raw materials, and sets up special personnel and special inspections for special materials such as alloy steel, low-temperature steel, and stainless steel, so as to completely prevent unqualified materials from flowing into the construction si.
On the basis of improving the welding efficiency of process pipelines, the project department continuously optimizes the construction organization pl.
As of August 7, the construction workers of the project department have completed a total of 430,000 inches of process pipeline welding, and the first pass rate of welding flaw detection has remained at about 9
