The local government shows the green signal only if the plant is designed under the published codes and standards.

It ensures the safety and reliability of the system.

Codes and standards provide single direction thinking to all.

Benefits of Referring Codes and Standards

In order to have consistency in design and to avoid having one project differ from others for cost-effectiveness. Many companies also generate their own recommended practices based upon the old projects. Recommended practices are the documents prepared by a professional group, committee, or company based upon good engineering practices held in the industry. What do You Mean by Recommended Practices? Piping Codes do not provide design consideration for standard fittings or components such as elbows, tees, flanges, valves, olets fittings, etc.ĪSME B16.9, ASME B16.10 ASME B16.5, etc. Piping codes provide design rules for non-standard fittings like miter bend and also for the reinforcement pad of stud-in or stub-on piping branch connections. In addition, criteria are provided to determine the minimum pipe wall thickness, material behavior due to the effects of internal or external pressure, dead weight, seismic loads, live loads, and thermal expansion/contraction. The piping codes provide speciﬁc design criteria for the activities such as material (MOC) selection, checking of allowable working stresses, and load criteria that must be considered for design per the particular application. Many of us (the designers and engineers) think that the terms code and standard are synonymous, but this understanding is incorrect.
