AFAA have decades worth of experience undertaking pipe stress analysis to most ASME, British Standards and UK Gas Industry standards in the oil and gas industry.
Most recently we have undertaken Option A and Option B pipe stress analysis, as required by IGEM/TD/13 for operation with hydrogen or hydrogen/methane blends. This will become increasingly important as parts of the UK gas network transition to hydrogen or hydrogen/natural gas blends.
Pipe Stress Analysis
Piping may be subjected to various types of dynamic loads, such as slug-flow, acoustic pulsation and water hammer.
Slug-flow
A slug of liquid formed in a vapour line creates a density discontinuity which produce unbalanced forces on bends and causes the piping system to vibrate.
Acoustic Pulsation
Resonance may be established from a pulsating flow from a reciprocating compressor, generating a high pressure pulsation.
Water Hammer/Surge Analysis
When the flow in a piping is suddenly altered, such as that caused by a slam-shut valve, a compression/rarefaction wave travels down the line causing the piping to vibrate resulting in potentially high stress and loads at supports and connected equipment.
Dynamic Analysis
Static analysis considers all environmental loads, including: thermal effects, pressure, weight and seismic loads.
We have worked closely with designers to offer a cost effective solution for readily creating pipe stress models using laser scan technology.
