Tube Sizes up to and Including 2.750" OD with a Maximum Wall of .125" Seamless tubing, formed by forging a rotating, heated, solid-steel round over a piercing point, inherently possesses some spiraling eccentricity, since it is not possible to
possible for high tube quality. Tube eccentricity is normally measured in two ways:on-line monitoring on a continuous basis during tube production, and off-line, more accurate measurements on an adequate number of tubes sampled from the production. On-line measurements are commonly performed using ultrasonic techniques [1, 2]. Piezo Diameter, Eccentricity, concentricity Micro-EpsilonDiameter, Eccentricity, concentricity. Diameter monitoring on seamless rolled rings. An important criterion for the quality or the wear of tubes in industrial applications is the dimensional conformance of the internal diameter over the complete

operation in seamless tube making. The system consists of generation and detection lasers and an interferometer located in a cabin outside the tube mill, and a fiber coupled inspection head located above the process line. Tube wall thickness and temperature measurements are used to guide mill adjustments to achieve the desired tolerances. Monitoring pipe wall integrity using fiber Bragg grating Nov 01, 2018 · Such a wall loss or eccentricity is measured by monitoring the group velocity and circumferential amplitude distribution of the L(0,2) mode. Experimental results demonstrate L(0,2) mode energy confinement in the thinner regions of the pipe wall and decrease in its group velocity as the pipe eccentricity increases.
With the development of modernization, the application of seamless tube becomes widespread. As the first process of seamless tube, piercing is vital for the quality of the tube. The solid round billet will be transformed into a hollow shell after the piercing process. The defects of hollow shell cannot be cleared in the following process, so a monitoring model for the quality of the hollow Process Monitoring and Fault Diagnosis for Shell Rolling Seamless tube rolling process is a computer supervisory and computer control industrial process. It need regularly acquire system state variables and equipment status to be used for display and control. Each cycle of seamless tube rolling production process will produce tens of thousands of process data.

Wu, (2013) A Generalized Stochastic Petri-Net Model for Performance Analysis and Allocation Optimization of a Seamless Steel Tubing Seamless Mechanical Tubing The minimum order quantity for standard seamless mechanical steel tube products is 10,000 pounds. For tube sizes that weigh more than 100 pounds per foot, the minimum is 20,000 pounds. These minimums apply to standard grades. Customers must order non-standard grades in a heat lot. We can provide a heat of non-standard grade steel in multiple sizes.
