Piping Systems Design

Pipes Connecting all the Process Components

Piping system design requirements span multiple engineering disciplines. Process engineering defines fluid flows, pressure, temperature and pipeline materials and sizing. Mechanical engineering develops the piping component specifications and their configuration requirements. Structural engineering contributes the support elements needed for gravity loads, flow induced forces, earthquake, wind, and thermal expansion of high temperature systems.

Piping Codes and Standards define the requirements for structural design but also reference building and civil engineering Codes to define the loads that must be considered. The piping Codes also define the documentation and the requirements for fabrication, inspection, and testing before the lines are placed into service. The most common Codes used for piping systems are:

• ASME Power Piping Code, B31.1. This is for boiler and steam generator proper piping but is commonly used for high-pressure steam piping systems.
• ASME Process Piping Code, B31.3. This is the most general industrial service piping Code and is the most regularly used.
• ASME Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids Code, B31.4.
• ASME Gas Transmission and Distribution Systems Code, B31.8.

ChemTech has employed additional Codes and Standards for specialized installations. These include guidelines published by the professional organizations ASHRAE, AISC, ANSI, API, ASCE, ASTM, AWS, AWWA, EJMA, NACE, NFPA, OSHA and PFI. ChemTech can help you determine the guidelines that apply to your project.

ChemTech can supply all aspects of the piping system design. Our engineers and designers are experienced with the necessary Codes and Standards and apply them to insure compliance. ChemTech’s engineers and designers understand these requirements and their impact on the cost and construct ability of the piping system.

ChemTech has developed specialized piping system designs including:

• Boiler House and Plant boiler feed water and steam distribution systems.
• Natural Gas collection, processing, and distribution systems.
• Chemical process operations, distillation, vapor condensation, heating, etc.
• High temperature residual products.
• Low pressure, high temperature vent vapor collection systems.
• Fluids with profound corrosive or erosive characteristics.
• Heat transfer oil (hot oil) piping, with special consideration of operator safety issues, fire prevention, and thermal cracking minimization.
• Insulation systems specially designed for the process’s thermal needs, the piping support systems employed, and the fluids being handled.
• Specialized systems such:
  • Glass and Polymer lined piping systems for corrosive contents.
  • Hot Oil jacketed piping for pitch and polymer processing.
  • Double containment piping for hazardous liquids.
  • Clean-in-place (CIP) fittings for food-quality piping.

ChemTech uses Design Flow System from ABZ, Inc. to analyze process flow and AutoPIPE from Bentley Systems, Inc. to perform pipe stress analysis for the designs.

Our engineers and designers have spent years developing, and are justifiably proud of, their piping design skills.
