Smpv License
Your reliable partner for obtaining SMPV licenses in full compliance with Indian safety regulations.
What is SMPV License?
The SMPV (U) Rules, govern the design, fabrication, installation, operation, and maintenance of pressure vessels used to store or transport flammable, toxic, or compressed gases.
“Pressure vessel” means any closed metal container of whatever shape, intended for the storage and transport of any compressed gas which is subjected to internal pressure and whose water capacity exceeds one thousand liters and includes inter connecting parts and components thereof upto the first point of connection to the connected piping and fittings, but does not include containers wherein steam or other vapour is or is intended to be generated or water or other liquid is or is intended to be heated by the application of fire or the products of combustion or by electrical means, heat exchangers, evaporators, air receivers, steam type digestors, steam type sterilizers, autoclaves, reactors, calorifiers, pressure piping components such as separators or strainers and vessels containing a liquid under a blanket of compressed inert gas.
This includes:
Aboveground & Mounded Storage Tanks
Road tankers (Mobile Pressure vessels)
- Cryogenic Storage Tanks.
Pressure vessels storing LPG, Propane, Ammonia, Nitrogen, etc.
Businesses must obtain a license under these rules to legally install and operate such systems.

General Exemptions
Nothing in these rules shall apply to vessels which form part of a processing plant. For the purpose of this rule, vessels forming part of a processing plant shall mean vessels in which a unit process or unit operation is carried out and vessels which contain, as a process requirement, compressed gas received from and consumed in the same processing plant, provided that the water capacity of the vessels shall be such that the gas stored therein at the maximum working pressure shall not exceed the requirement for feeding the consuming points for a period not exceeding sixteen hours at the designed flow rate.
