Piping System Design
New Piping Systems
Existing Piping Systems with Problems
Existing Piping Systems Being Rerouted to Improve Process Conditions
APPLICATIONS
Incorrect setting of spring hangers, strut rods, and other supports
Incorrect installation sequence of supports and restraints.
Flange misalignment
Temporarily using come-a-long, portapower, jack screws, etc. to force the piping into position. When these are released the loads are transferred on to the equipment
Constant high vibrations
Vibration levels increasing over the years
Bearings and seals wear out quickly
Piping requires hot alignment to reduce vibrations
Lack of fixed restraints and guides
COMMON MISTAKES
Piping systems are designed with the intent that piping stresses and piping loads on connected equipment are below their respective allowables. ASME B31 piping codes provide guidance to help achieve safe designs. It is then the responsibility of the design engineer to complete the piping design to be economical to construct, require low maintenance, and have high reliability.
ANALYSIS
Piping stress analysis is used to design a system with adequate flexibility and to specify supports and restraints. A complete piping system design includes: design and specification of supports, restraints, valve selection, specification of specialty items (such as expansion joints, orifice plates, pressure safety valves, etc.), and bill of materials. Piping designs will be provided to the level of detail requested. We offer everything from full designs, to piping layout or stress analysis only.
