Large Diameter, High Pressure Blowoff Design
Publication: Pipelines 2022
ABSTRACT
Design and installation of blowoff and drain line assemblies on transmission waterlines is commonplace. However, design of these accessories on large diameter transmission waterlines can be quite complex, especially in high pressure applications. A design and operation balance needs to be found between the need to drain the line in a planned or emergency shutdown versus the potential damage to the assembly and/or the environment. This paper discusses the different design considerations, including, but not limited to, required pipeline drain time, maximum flow rates, client preferences, environmental protection, operatory safety, durability, and ease of operation.
