Pipe Stress Analysis

Pipe stress analysis is at the core of what we do here at our Singapore offices in BroadTech Engineering.
Unlike a solid bean structure, which is predominantly designed for strong support, a pipe structure, which is tubular and hollow in nature is designed primarily for the purpose of transmitting fluid materials.
Because a Pipe structure by its very nature is not built for strength, it is important for a professional pipe stress analysis to be conducted to ensure the structural integrity of the piping system as a whole

Pipes are used extensively in Industrial plants, such as Chemical processing refineries and Power generation facilities.
In terms of applications in Industrial processes, pipe plays a central role in

1. Facilitating engineering processing

2. Transmission of gas and liquid in Gas transmission piping system and Liquid distribution pipe systems

Why is Pipe Stress Analysis Necessary?

Pipe stress analysis necessary for the implementation of any piping system. Through Pipe Stress Analysis we are able to help you address the following piping engineering challenges, such as

1. Ensure Structural Integrity of Pipe Structure

Ensuring structural integrity and safety of the piping structure when subjected to various external temperature conditions via ensuring that the pipe system structure is thoroughly supported throughout.
*This helps to prevent any unsightly sagging or physical deflection due to loading forces arising due to its own weight.

2. To Account for Thermal Expansion

– To ensure physical deflections are well controlled within designed specification when subjected to external thermal and Force loadings

– To evaluate and check to ensure that the force loadings and Moments exerted on the connected processing equipment or tank vessel due to thermal expansion does not exceed beyond the acceptable safety limits.

– to check and ensure that the net stress values in the pipework system in both the extreme cold and hot conditions are within the allowable safety limits.

– This helps to ensure compliance with regulatory and legislative safety policies and design guidelines

3. Ensure Proper Transmission fluids

Ensuring the proper functioning of the piping system when used for transmission fluids of various conditions, such as

– Fluids which are in Liquids or Gaseous state

– Fluids of varying viscosity, from thin liquids to highly viscous liquids

– Fluid of various thermal temperature, from cold to hot to super-heated

– Fluid that is transmitted under various pressure conditions/values from low pressure to highly compressive conditions

4. Design Optimization to Minimize Cost

Minimize the material cost of implementing the Pipe system, by optimizing the piping system to use the minimum pipe wall thickness, while at the same time ensuring that its performance meets the fluid Temperature and Pressure requirements.

Key Components that make up a Piping Systems

1. Restraints

Piping restraints are devices which resist, prevents, or limits the free movement of the pipe thermal expansion or contraction.
The type of pipe restraints can be either Directional, Rotational or a Combination of both.

2. Anchors

Pipe anchors are rigid restraint which is able to offer substantially full fixed, (ie. Encastre or built-in).
It is designed to ideally prevent lateral pipe movements or pipe bending moments from passing through them.
In practice, True anchoring effects are usually difficult to achieve.
A seemingly solid gusseted bracket welded to a housing column does not qualify as an anchor if the column does not have the strength to resist the force loading applied on it.

3. Expansion Loops

Pipe Expansion loops are built-for-purpose engineered devices which are able to absorb thermal expansion in the pipes.
In practice the thermal expansion loops device is often used in combination with restraints and cold pulls.

4. Neutral Planes of Movement

Neutral Planes of Movement refers to the reference planes on the 3 axes of a turbomachinery or pump device from which thermal expansion of the machine begins (eg. the Secured end of a turbine casing).
Usually, this information is provided by the equipment manufacturer’s official specification.
If the information is not available from this source, the fixed points of the machine can be determined by inspection and a calculation of the estimated turbine thermal expansion.
A pipe restraint, when placed in alignment with a neutral reference plane, can help to effectively suppress differential expansion loading forces between the pipe and the machine.

5. Spring Hangers

Spring Hangers are used to provide providing structural support to Piping system that is subjected to Vertical thermal movements.
Standard available single coil spring units are suitable for most implementation.
According to Hooke’s law, the spring’s structural supporting capability will vary in direct proportion to the degree of displacement the spring undergoes due to thermal expansion movement of the pipe.
This thermal variation between cold and hot condition should be within 25 and 50% of the hot loaded condition.

6. Solid Vertical Support

In regions where vertical thermal movement does not result in undesirable effects, or where vertical movement is intentionally prevented or directed, solid supports in the form of rollers, rods or slippers are recommended.
It is important that free horizontal movement of the pipe is not hindered unless horizontal restraint is desired.
Note that it is important for the Slippers and rollers to be well designed and lubricated.

How is the Pipe Stress Analysis Carried Out?

The piping system design is the first 3D modeled using computer-aided simulation analysis software tools.
The 3 dimensional CAD model is constructed base on input information from general piping arrangement drawings, piping isometric CAD drawings, and piping and valve technical specifications.

Once the piping system is accurately modeled into the engineering simulation software system, taking care to set the boundary conditions, comprehensive stress analysis calculations are done.
Base on the feedback from the simulation analysis results, precise design modifications can be made to the 3D CAD model to enhance its structural integrity and ensure compliance with the specific regulatory safety requirements.
