The research on the application of the pipe jacking in the repairs of the water supply pipes

A prediction model was set up for the security of water supply pipe leakages in water supply industry,and the genetic algorithm(GA) was introduced to optimize that model.

Study on velocity for heterogeneous flow in horizontal pipe;

Method of Neural Network in Velocity for Heterogeneous Flow of Slurry Flow in Horizontal Pipe;

Moreover, large eddy simulation ( LES) theory model is briefly reviewed in this paper, and then a calculation case of LES for horizontal pipe to reveal flow field under the interaction between two different velocity streams was carried out by using parallel computer and computational fluid dynamics (CFD) code.

Based on the detailed introduction of research and application of hyperbaric welding repair technology all over the world, the authors think that it is necessary to develop the hyperbaric underwater pipeline repairing system domestically, and analyze the key points in developing this system.

A new technology which firms the underwater pipeline by fiber reinforced mats is put forward.

The intent of this project is to find a solution of underwater dry maintenance and repairs for underwater pipeline and structures.

Predicting residual life of water injection pipeline based on support vector machines.;

Systematic design of robot used for detecting water injection pipeline in oilfield;

Based on the relevant data and methods provided,a formula for calculating economic flow rate in water injection pipeline is derived combining with the characteristics of water in-jection engineering in oilfields.

Service methods and instrumentation for offshore pipelines are different from those on land because of their vastly differing performance and environments.
