Currently, reinforced 3PE steel pipes are widely used across various industries due to their excellent corrosion resistance. However, one major challenge is the low wall thickness accuracy, often resulting in uneven thickness. This inconsistency can significantly affect the overall performance and durability of the pipe, ultimately shortening its service life. To address this issue, manufacturers have implemented several effective measures to enhance the wall thickness precision of reinforced 3PE steel pipes.

How to Improve the Wall Thickness Accuracy of Reinforced 3PE Steel Pipes
Uniform Heating of the Tube Blank
Ensure consistent and even heating throughout the tube blank. Rapid temperature fluctuations must be avoided to maintain a stable heating process, which helps prevent structural inconsistencies.
Proper Adjustment of the Centering Roller
Confirm the correct positioning of the centering roller. Adjustments to the core roller’s central axis and opening angle are critical for maintaining uniform deformation during rolling.
Accurate Installation of Rolling Tools
The rolling tools must be aligned precisely on the rolling line. Ensure that both the upper and lower roller gaps, as well as the left and right guide gaps, are equal to achieve symmetrical rolling.
Use of Mandrels for Thick-Walled Pipes
Select mandrels suited for processing thicker-walled pipes. Uniform pipe wall thickness reduces the likelihood of mandrel deformation, thus improving dimensional control and accuracy.
Process Optimization
Refining the manufacturing process can also improve wall thickness accuracy. This helps prevent mid-section thinning and ensures the wall thickness remains within the specified control range.
