Spectra Energy Corp is one of North America’s premier natural gas infrastructure companies serving three key links in the natural gas value chain: gathering and processing, transmission and storage, and distribution. Spectra Energy conducts extensive environmental and archeological studies as part of the pipeline design process. This includes coordination with local, state and federal agencies … Continue reading How “Spectra Energy” Planned Pipelines and Routes
Pipelines like other slender strcutures with compressive forces, can buckle globally if the axial compresssion goes beyond a certain level. Buried pipeline normally tend to buckle in upheaval direction (upheaval buckling) and exposed pipelines normally tend to buckle laterally (lateral buckling). In most cases, evaluations relevant to the global buckling threat will already start taking … Continue reading Pipeline Global Buckling
Why ? The reasons one does a pipe stress analysis on a piping system are as follows to comply with legislation to ensure the piping is well supported and does not sag or deflect in an unsightly way under its own weight to ensure that the deflections are well controlled when thermal and other loads … Continue reading Pipeline Stress Analysis
“All bends are elbows but all elbows are not bends.” Infact, the pipe is bent to form an elbow. Elbows are pre-fabricated and are firm in design. There are issues with bends since the tickness at the bend radius reduces as we bend the pipe. Sharp bends are normally called Elbows. Bends typically have a minimum bending radius … Continue reading What is the difference between elbow and bend in piping?
Hydrate and wax plugging often limit subsea tieback distance and deepwater field development, and can make remote oil and gas resource recovery uneconomic or excessively risky. Maintaining the produced fluids temperature outside the critical hydrate or wax formation zone often can be done using a high-performance passive insulation system such as pipe-in-pipe. However, flow assurance … Continue reading Electrically heated pipe-in-pipe (EHPIP) – A qualified reelable technology to meet flow assurance challenges
Directional boring, commonly called horizontal directional drilling (HDD), is a steerable trenchless method of installing underground pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area. Directional boring is used when trenching or excavating is not practical. It is … Continue reading Directional Boring
