Piping system must pay attention to the good of plan qualification both in technical term and economical terms. Qualification plan of piping system in term of mechanical can be found by doing some analysis, such as determination of pipe wall thickness, hydraulic analysis, pipe stress analysis, and analysis flexible pipe. While in terms of economical, plan of qualification piping system depends on the financial policy of the company or industry but keeping in terms of eligibility based on the mechanics that have been set in the Code Standards. This condition is to ensure the security and use current piping system plan which is operated safely for the environment.
Planning piping system can use rules code and standard. Code and standard that are applicable in the planning piping system, namely:
a. ASME B31.9 Building Services Piping
b. ASME B31.8 Gas Transmission & Distribution Piping
c. ASME B31.7 Nuclear Power Piping
d. ASME B31.5 Refrigeration Piping
e.ASME B31.4 Liquid-petroleum transportation piping system
f. ASME B31.3 Process Piping on Petroleum Refineries, Chemical, Pharmaceutical, Textile, Papper, Semiconductor, and Crycogenic Plant.
g. ASME B31.2 Fuel Gas Piping
h. ASME B31.1 Power Piping
i. API 5L Spesification of Line Pipe Material
j. API 576 Pipeline Coating
k. DnV 1981 Rules For Submarine Pipe Systems
l. DnV RP F105 Free Spanning Pipelines
m. DnV RP E305 On Bottom Stability Design Of Submarine Pipeline
n. ANSI B16.5 Pipe Flange and Flange Fitting
