Home > Career > Overview


During the early 1980s, natural gas was discovered in the Gulf of Thailand. With this discovery,
the government supported the use of Liquefied Petroleum Gas (LPG), fostering strong demand
for large gas storage tanks.

On the 21 April 1982, Unimit Engineering Public Company Limited was established to fulfil that
demand and minimize reliance on imports.  Joining forces with a Taiwanese engineer,  who
possessed considerable knowledge, skill, and experience in the design and production of large
gas tanks, the company started to design and produce tanks with the highest security standard,
using high-quality steel and a careful welding process. Every welding point was tested and inspected
by X-ray and Hydro-static tests.

Due to the increasing demand of its customers and the continuous expansion of its business, the
company has increased its registered capital several times . Over the years, the company has
developed new production processes to extend its business into sectors other than the petroleum
and petrochemical industry. Even though Unimit started off solely as a manufacturer of LPG and
other gas storage containers, at present. its business activities cover five categories:

1. Large pressure vessels and other facilities and parts (qualified ASME standard):
    • Spherical tanks, vertical columns, horizontal drums for the storage of pressurized gases such
       as LPG, ammonium (NH3), carbon dioxide (CO2), liquid nitrogen (N2)
    • Transportable vessels/tanks to be installed on trucks or rail cars (i.e. lorry trucks)
    • Distillation towers/columns for oil refineries and petrochemical industry
    • Reactors used in various industries
    • Jacketed vessels, namely two-layered pressure vessels, used in the food industry
    • Boilers used in various industries
    • Heat exchangers used by oil refineries and petrochemical industry
    • Air receivers and steam drums (used in power plants)
2. Machinery Parts:
    • Fan casings for air pre-heater parts (used in power plants)
    • Emission stacks, incinerator parts (used by industrial plants)
    • Waste water treatment and seawater desalinization systems
3. Non-Pressure Tanks: large chemical API tanks for chemicals or resins, tank farms at oil refineries
4. Steel Structure: piping, stand, rack, support, mostly for the petrochemical, energy, and chemical
5. Mechanical Installation and Assembly of Machinery Parts and Equipment: mostly in conjunction
    with supply of pressure vessels and steel structures, but also as stand alone project.
