Piping & Process Engineers

New to Aienginear? These are the pages engineers use most. Each guide explains the engineering basis behind the numbers, and each calculator shows its formulas and the code clause it follows, so you can check the result rather than trust a black box.

Piping fundamentals

• Pipe and pipe class – how a piping class ties together material, rating, wall thickness and fittings for a service.
• Pipe sizes and schedules – NPS, outside diameter and wall thickness per ASME B36.10M and B36.19M.
• Carbon steel piping materials and ASTM A105 forgings – grades, chemistry, mechanical properties and where each is used.
• Types of pipe fittings and pipe elbow dimensions – ASME B16.9 dimensions with printable tables.

Engineering calculators

• Pipe support spacing calculator – maximum span from stress and deflection limits, including hydrotest load.
• Steam pipe sizing calculator – line size from velocity and pressure-drop criteria.
• Pipe pressure drop calculator, orifice plate and venturi meter flow calculators to ISO 5167.
• Hydrotest pressure calculator and tank volume calculator for site and commissioning work.
• See all tools on the engineering calculators page.

Plant maintenance and careers

• Plant turnaround and shutdown management – planning, execution and safe start-up.
• Heat exchangers – types, inspection and maintenance practice.
• 50 piping interview questions and answers for engineers preparing for site and design roles.

How we keep content accurate

Articles cite the code or standard edition they rely on and are revised when those editions change. Calculators run entirely in your browser, so nothing you enter is uploaded. Results are intended for learning, checking and preliminary design; final design must always be verified against the governing code, your project specification and a qualified engineer’s review. If you spot an error, please tell us through the contact page.
