ASME B31.11: A Standard for Slurry Transportation Piping Systems
Slurry transportation is the process of moving solid materials suspended in a liquid medium through pipelines. Slurry pipelines are used for various applications, such as coal, mineral ores, concentrates, and other industrial materials. Slurry transportation piping systems require special design, materials, construction, inspection, testing, operation, and maintenance to ensure safe and efficient operation.
ASME B31.11 is a standard that prescribes the requirements for slurry transportation piping systems. It is part of the ASME B31 Code for Pressure Piping, which covers piping systems for different fluids and services. ASME B31.11 was first published in 1989 and has been revised and reaffirmed several times. The latest edition is ASME B31.11-2002 (R2008), which was last reviewed and reaffirmed in 2008[^1^]. However, there is a newer edition of ASME B31.4-2012, which consolidates and revises ASME B31.4-2009 and ASME B31.11-2002 (R2008)[^2^].
ASME B31.11 applies to piping systems transporting aqueous slurries of nonhazardous materials between plants and terminals, pumping and regulating stations. It covers the design, materials, fabrication, erection, examination, testing, inspection, operation, and maintenance of such piping systems. It also provides guidance on slurry rheology, flow regimes, pressure drop calculations, erosion-corrosion, and slurry sampling[^3^].
ASME B31.11 is intended for manufacturers, designers, operators, owners, and regulators of slurry transportation piping systems. It aims to promote safety, reliability, and efficiency of slurry pipelines. It also helps to harmonize the requirements and practices for slurry transportation with other piping codes and standards.Slurry pipelines have several advantages and disadvantages compared to other modes of transportation. Some of the advantages are:
Slurry pipelines can transport materials that are difficult or impossible to move by other means, such as coal, iron ore, phosphate rock, and oil sands.
Slurry pipelines can reduce the environmental impact of mining and processing operations by minimizing the need for trucking, railroads, roads, and conveyor belts.
Slurry pipelines can lower the operating costs and energy consumption of transporting materials over long distances by using pumps and gravity.
Slurry pipelines can operate continuously and reliably with minimal maintenance and supervision.
Some of the disadvantages are:
Slurry pipelines require high initial capital investment for construction, engineering, and permitting.
Slurry pipelines may face technical challenges such as erosion, corrosion, leakage, blockage, and sedimentation of solids in the pipeline.
Slurry pipelines may pose environmental risks such as spills, contamination of water sources, and habitat disruption.
Slurry pipelines may encounter social and political opposition from landowners, communities, and regulators along the pipeline route.
Therefore, slurry pipelines should be carefully designed, constructed, operated, and maintained to optimize their performance and minimize their drawbacks. 061ffe29dd
