This study presents a new mechanical tube cladding process named punch plastic deformation pipe cladding (PPDPC) based on local deformation by pressing a punch into the inner layer of the bimetal tube. To investigate the capability of the process, stainless steel tube (as the inner layer) is bonded to a carbon steel pipe (as the outer layer) to fabricate a bimetal pipe. Shear punch tests were u...

Corrosion of offshore oil and gas pipelines is an important problem that can generate catastrophic failures if not adequately managed. The issues are more important and critical for deepwater pipelines due to complexity of the designs and also due to difficulty in inspection, monitoring, and repair. Pipelines exposed to these severely corrosive environments require the use of corrosion resistan...

CRA-lined pipelines, i.e. pipes with an inner pipe of a corrosion resistant alloy inside of a ferritic steel pipe carrying the hoop stress, pose a challenge to inspect with conventional in-line inspection technologies. Existing UT technology is not able to inspect through the interface of a CRA and a ferritic steel component. Additionally, current MFL technology is not able to sufficiently magn...

Corrosion may develop and grow on steel pipes under layers of insulation cladding. Inspection the through these protective is paramount importance. Pulsed eddy current (PEC) a primary non-destructive testing (NDT) technique candidate for this type inspection as it requires no contact with material. To overcome variability in PEC signals due to variations cladding thickness, large measurement se...

In this study, a nickel cladding layer with bionic convex strip structure was applied to the surface of an aluminum alloy drill pipe, and laser technology used improve wear resistance pipe. Firstly, by observing morphological characteristics shell surface, ratio width strips spacing between obtained as 0.39–0.53, thus model constructed. Numerical simulations were performed, results showed that ...

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. They made by welding resistive material to commonly available carbon steel pipes. The production of pipe bends with supercritical bend 0.7D, which part serpentine systems, is very complex and technologically demanding because often undesired cracks occur. To increase the ser...

Sockeye is a heat pipe analysis application based on the Multiphysics Object-Oriented Simulation Environment (MOOSE) finite element framework. The primary purpose of to provide transient simulation tool be used in nuclear microreactor designs. provides capability perform one-dimensional, two-phase, compressible flow working fluid and two-dimensional, axisymmetric conduction for cladding its sur...

Plasma cladding coupled induction heating was developed and successfully used to fabricate Ni60A coating on the surface of copper pipe. By matching swing arc with rotating pipe, efficiency as high 32.72 mm2/s. From head tail coating, wear resistance changed from 4.5 1.8 times that pure copper. During process constant current, temperature zone bath depth gradually increased. The corresponding di...
