Another variable in the design of pipe support, seismic bracing, or hangar design is what is/will be inside the pipe, and how the temperature affects the pipe material. Much pipe stress analysis, determined by the force of the liquid running through it, needs to have thermal stress factored to give the bracing and anchorage the flexibility the pipe needs as it expands and contracts. This is a very speciality engineering item and Zenith is one of the few firms who are experts in this field.
The principal of Zenith Engineers Inc. has developed programs and systems that help shorten turnaround times for pipe stress analysis and related specialty engineering, and our team has supported projects in life science, healthcare, pharmaceutical manufacturing, and aerospace. In pipe support design, our engineers consider fluid temperature, pressure, and thermal growth, and prepare designs in compliance with ASME B31.1 and ASME B31.3. An independent engineer can be a helpful resource for owners and contractors on this type of work.
Frequently Asked Question's
Pipe stress analysis evaluates stresses in a piping system from pressure, weight, thermal expansion, and other loads, typically against codes such as ASME B31.1 or B31.3. Zenith Engineers Inc. performs this analysis using tools including CAESAR II and ANSYS.
Pipes expand and contract as the temperature of the fluid inside changes. Supports and bracing that do not allow for this movement can add stress to the pipe and connected equipment. Zenith calculates nozzle loads, loop flexibility, and thermal growth.
Pipe supports carry the weight and loads of a piping system to the structure. Zenith's pipe support work typically involves larger industrial piping supported from below. Seismic bracing restrains pipes against earthquake movement, with requirements set by the governing code.
Zenith's principal has assisted projects in life science, healthcare, pharmaceutical manufacturing, and aerospace, and our engineers bring backgrounds in energy, water treatment, and power plants. Zenith designs pipe supports and pipelines in compliance with ASME B31.3 and B31.1.
