Gravity effects are generally ignored in the study on the pipe vibration. However, in this
paper, the effect of gravity on the nonlinear vibration of a pipe conveying fluid has been …

The acceleration of global urbanization and an increasing intersection of roads and buried
pipelines pose a certain threat to the operation safety of pipelines. In this paper, the …

In this paper, the stability of the pipe-in-pipe (PIP) conveying fluid system with intermediate
supports are studied. The focus of the study is mainly on the influence of the intermediate …

Internal replacement pipe (IRP) systems are becoming an effective rehabilitation technique
for legacy oil and gas pipelines with defects and discontinuities. Under repetitive traffic …

The internal replacement pipe (IRP) is a develo** trenchless system utilised for restoring
buried steel and cast-iron legacy pipelines. It is crucial to ensure that this advanced system …

Abstract Pipe-in-pipe (PIP) has become an acceptable system for the rehabilitation and
repair of natural gas distribution networks. Damaged host pipes usually contain defects such …

Structural internal replacement pipe (SIRP) systems are emerging composite technologies
for the repair of circumferentially cracked host pipes or pipes with joints subject to lateral …

During the production of high-temperature, high-pressure (HPHT) gas wells, the gas
entering the production tubing column induces vibration, which in turn leads to changes in …

In this paper, the nonlinear forced vibration of a fluid-conveying pipe-in-pipe (PIP) system is
studied. The dynamic model of PIP system considering geometric nonlinearity and insulation …

Internal replacement pipe (IRP) systems are a novel trenchless technique that is gaining
interest in the rehabilitation of damaged legacy pipelines distributing natural gas …
