Ultrasonic testing of seamless steel pipes with matrix arrays

Seamless pipes are demanding and high-technology products. Especially in the oil and gas industry, but also in power plants, they are subject to the most stringent quality requirements. Ultrasonic NDT benches are ideal to detect potential inhomogeneities at industrial speed in rough environments. Using Phased-Array technology with additional Paint-Brush technique gives the opportunity of gapless detection up to ± 45° relative to the axial orientation at full production speed [1]. The use of 2D-Phased-Array Transducers has the potential to overcome this limitation, since they naturally allow to detect defects under any orientations. Within this paper, we present a fully parallelized, […]

Steel pipesSteel pipesSteel pipesSteel pipesSteel pipes

Steel pipes are cylindrical tubes made from steel that are used many ways in manufacturing and infrastructure. They’re the most utilized product made by the the steel industry. The primary use of pipe is in the transport of liquid or gas underground—including oil, gas, and water. However, pipes of varying sizes are used throughout manufacturing and construction. A common household manufacturing example is the narrow steel pipe that runs the cooling system in fridges. Construction uses pipes for heating and plumbing. Structures can be built using steel pipe of varying sizes, such as handrails, bike racks, or pipe bollards. William […]

Part 1. How to control the deformation of precision seamless tubes during the cold drawing process

This paper deals with the deformation of precision seamless tubes during the cold drawing process, using Finite Element Methods. The value of strain obtain by stereology measurement of degree grain boundaries deformation are compared with simulation result for each drawing pass. The material chosen was the E235 and E355 steel grade, which is drawn from the initial dimension of Φ70 x 6.3 mm to the final dimension of Φ 50 x 3.75 mm by two passes. FEM Software DEFORM 2D with the Lagrangian method is used to numerical analyses of the cold drawing process.   1 Introduction Cold drawing technology […]

Effect of Groove Designs on Residual Stress and Transverse Shrinkage in GMAW and PGMAW of A333 Seamless Steel Pipes

The e®ectiveness of weld joints primarily depends on the fusion of base metal, minimum heat- a®ected zone (HAZ) and lesser residual stresses. The severity of thermomechanical e®ects e.g. weld shrinkages and residual stresses is signi¯cantly minimized by narrow gap welding tech- nique over the traditional welding. This work describes the welding of A333 Grade 3 steel pipes by the application of GMAW and PGMAW techniques. The analysis is made to capture the e®ects of groove designs on residual stress and transverse shrinkage. The process parameters used for the analysis are voltage, current and welding speed. In this work, narrow groove […]

The influence of the processing parameters on the performance of the two-roll piercing operation

The influence of the processing parameters on the performance of the two-roll piercing operation Article in Journal of Mechanical Working Technology · September 1987 Abstract Over the past decade, the demand for higher quality oil-country tubular goods has been increasing and to meet this demand, seamless-pipe mills have been active in developing new and improved hot-mill practices. For a hot-rolled tube on the cooling table, higher quality means more precise dimensions and improved surface quality. It is reported that pass design, piercer set-up and operating parameters have substantial influence on both dimensional and surface quality. Experimental work was conducted to […]

gas piping system Installation Inspection

Natural gas pipe mainly contains a gas mixture called methane. Natural gas is formed by chemical changes in the remains of plants and animals that existed millions of years ago and remains deep in the Earth’s crust over time under the influence of heat and pressure. Natural gas pipe is usually found in oil-bearing or non-oil-bearing reservoirs. Today, natural gas is used as an important energy source for heating homes and workplaces, and given the risks posed by natural gas, gas piping system installation inspections by authorised agencies are important in this regard. Natural gas installations are used for residential heating, […]
