Case Studies: Pipework Analysis & Solving Pipework Issues |
Pressure Relief Pipework Analysis and Design
The Problem DC White Engineering Consultants Ltd were commissioned to design and assess pressure relief pipework. This was to be installed to an existing pressure vessel weighing several hundred tonnes containing process chemicals. The piping arrangement was assessed against the ASME B31.3 Process Piping code using CAESAR II software. Internal pressure, thermal loading (expansion) and dynamic vibration were included within the assessed load cases and the analysis [...]
Substantiation of Piping Package
The Challenge: DC White were commissioned to substantiate a piping package to several codes, ASME B31.3 for the pipework and API 610 for the nozzle loads. A previous report found that the loads acting on the pump suction and discharge nozzles were failing to meet the requirements of API 610. The recommended modifications were to place the pump on a sliding baseplate and include an additional support [...]
Piping Stress Analysis – Europa Crown
This project provided piping stress analysis for Europa Crown. The problem The project involved a piping stress analysis for several steam and condensate lines which are part of a large vegetable oil refinery. The client had no previous experience with pipework construction and needed to know where, and how, the system should be supported. Once the supports had been added to the system, it was substantiated [...]
St. Pancras Station Analysis of Sprinkler System for Tyco Wormald
Life would be a lot easier for designers and engineers if we could remove, eliminate or demolish what exists already. The ability of a good designer or engineer is to produce designs that work with and compliment an existing design, not bulldoze the merits of our engineering heritage. DC White thrives on these challenges - such as this one, presented to us by Tyco Wormald. Historic Project: [...]
Channel Tunnel Rail Link Piping Bracketry
Following our design work for the London Underground Jubilee line, we were asked to design the brackets that would hold the fire mains and drainage piping in the 43 kilometres of the Channel Tunnel Rail Link system. The brackets were required to support the self weight of the pipework as well as surge pressures. Surge Analysis Although the fire mains were permanently filled with water, [...]
Piping Safety Assessment at Major Chemical Plant
Background One of our major clients needed to extend the life of an ailing pipeline which had significant visible corrosion. It was commercially critical for the client to continue running the plant until the next scheduled maintenance period. Our job was to analyse the pipeline in its corroded condition and evaluate its on-going suitability for service. The Problem The line in question carried both toxic [...]
Superheater – Boiler Penetrations
Seismic Integrity Assessment Case Study DC White were tasked to assess the seismic integrity of the Hunterston B & Hinkley Point B boilers, in particular the superheater steam pipes and their penetrations into the reactor pressure boundary. These were seen to be potentially vulnerable to earthquake motions with the possibility that the boilers could topple and release steam into the reactor. The seismic response is dominated by [...]
