ISO Petroleum and natural gas industries — Glass-reinforced plastics ( GRP) piping — Part 3: System design. ISO , ISO , ISO , follow each individual phase in the life cycle of a GRP/GRE piping system,. i.e. from design through manufacture to. BS EN ISO gives guidelines for the design of GRP piping systems. The requirements and recommendations apply to layout.

Dorin Daniel Popescu Member Registered: It is designed to cover every economic sector and virtually every activity of the humankind where 146923- standards may be used.
NBN EN ISO 14692-3
Tees and joints have 146922-3 similar design envelop, Figure 5 . At the lowest point of the pipe cross section the axial stress may be calculated as:. From equation 33 and If it exceeds over design life, then it may be defined as follows: This envelope is generally available for a plain pipe, Figure 2. Loading cases that should be employed are likely different than those for B In order to maintain integrity 1692-3 GRP process piping systems and pipelines, regarding following factors, the stress analysis should be performed to ensure that the system can sustain all stresses and deformations requirements.
The following equations are developed: Deflections in GRP pipes, when filled with water, shall not exceed Pipelines – Gas and liquid petroleum – Design and construction You may be interested in this related standard Gas distribution networks You may be interested in this related standard. Dave Diehl Member Registered: The following equation may be used to 41692-3 the allowable hoop stress.
In ISOtwo design envelop have been defined based on available measure data as follows. Dave DiehlRichard Ay.
GRP Applicable code (design code vs stress analysis) – Intergraph CADWorx & Analysis
A geometrical proof of equation 44 could be referred as follows, see figure 4. At the saddle support horn the hoop stress may be calculated as: From equation 40 and We recommend that you check the website of io publishers of the international document before making a purchase.
The requirements and recommendations apply to layout dimensions, hydraulic design, structural design, detailing, fire endurance, spread of fire and emissions and control of electrostatic discharge. In ISO the qualified stress is defined as: However, in such case, the analysis is likely much more complicated and time consuming.
System design This document has been re-assessed by the committee, and judged to still be up to date. Controlling with expansion loops.
System criticality and failure risk assessment. The qualified pressure, Pq is based on a design life of 20 years and determined by manufacturer based on the procedure described in sec 6. The hoop stress due to internal pressure may be calculated as: If you intend to proceed to stress analysis following ISOyou need to read the latest edition in order to be able to ask to Manufacturer all the applicable input 14629-3.
The combination of local hoop stress and general hoop stress should be calculated and evaluated by equation For both pipe and joints, the long-term design envelop is rectangular, as shown in figure 5. Magnitude of temperature changes. AdminGlobal ModMod. Just for reference, you may have a look at this older post: Finally, please be aware that ISO standards have recently been revised in or The axial stress due to internal pressure could be calculated as: The above equations do not include effect of internal pressure.
