Overview

What are the SMPV (U) Rules 2016?

The SMPV (U) Rules 2016 are Indian regulations dealing with the safety, design, manufacture, installation and use of pressure vessels and associated systems. The full form is the Static and Mobile Pressure Vessels (Unfired) Rules 2016, framed by the Government of India under the Petroleum and Explosives Safety Organisation (PESO).

These rules cover the design, manufacture, inspection, installation and use of pressure vessels used for the storage and transportation of compressed gases. Without the correct approvals, a company can face safety hazards, legal trouble and non-acceptance of its equipment, leading to delays and missed opportunities. Industries must therefore obtain the required approvals, certifications and compliances.

Key features of the rules

Applicable to both static and mobile pressure vessels
Ensure the safe handling of high-pressure gases
Fall under the purview of PESO regulations
Mandatory for industries using LPG, CNG, chlorine and ammonia
