Features of industrial gases sold
by Osaka Gas Liquid
Environmentally friendly
Osaka Gas Liquid's liquefied gas products are produced from oxygen, nitrogen, and argon in the air and carbon dioxide gas supplied from adjacent plants at power-saving and high-efficiency liquefaction plants that effectively use the cryogenic energy from liquefied natural gas (LNG), which is a feedstock for city gas.

How to supply industrial gases
We will make a proposal based on the amount of usage.
Liquefied gas storage tank (CE) method
A vacuum liquefied gas storage tank (CE) that stores liquefied nitrogen (-196°C), liquefied oxygen (-183°C) or another low-temperature liquefied gas and an evaporator for vaporizing and raising the temperature of the liquefied gas are installed at the plant site to provide near room temperature gas.
Amount of usage (approximate): 3,000 m³/month or more
Schematic flow chart
-
Individual cylinder and cylinder bundle methods
- Individual cylinder method
-
Gas is filled and supplied in a 47-liter capacity cylinder.
Furthermore, by installing two systems each of which consists of around 10 of these cylinders connected with a header, gas supply can be switched manually or automatically between the two systems.
- Cylinder bundle method
- Gas is supplied by installing a unit consisting of around 10 to 20 cylinders connected on a trestle.
Amount of usage (approximate): 200 to 2,000 m³/month
-
LGC method
- Liquefied gas is filled into a 175-liter capacity portable container or a 1,000-liter capacity mobile container. A multiple number of these containers are stocked for gas supply according to the amount of usage.
Amount of usage (approximate): 1,000 to 3,000 m³/month
Gas supply for purging work and pressure and airtightness tests
We can also supply gases for a short period of time for purging work and pressure and airtightness tests of gas tanks, LPG facilities, piping, etc.
We own ancillary equipment according to your usage.
Other supply method
NICE-crete method
(Pre-cooling of concrete)
We provide quality control and refrigeration management of concrete, from cooling to casting, based on our extensive experience and track record in cooling various structures for various purposes, including use in preventing cracking of large-scale high-strength concrete.
The Nitrogen Cooling for hi-Endurance Concrete (NICE-crete) method is a new pre-cooling technique that uses liquefied nitrogen as a refrigerant. Using cryogenic liquefied nitrogen as the refrigerant has removed the limitation in refrigeration volume and expanded its applications in prevention of cracking under the conditions that pre-cooling with cold water or ice alone had been impossible to prevent cracking. Moreover, it can improve the strength of structural concrete as well as not affecting the quality of concrete. We have established concrete quality control and refrigeration management methods, from cooling to casting, based on our extensive experience and track record in cooling various structures for various purposes, including use in preventing cracking of large-scale high-strength concrete. Furthermore, since we have developed refrigeration facilities for both field installation and plant installation, we can perform the most appropriate cooling work according to the grade and cost required by the customer, adapted to the concrete cast volume, cast speed, site size and various other conditions.
Applications of the NICE-crete method
- 1. High-strength concrete structures
-
・ PC bridge
・ PC tank and dike
・ PC silo
・ High-rise RC
- 2. Concrete structures and piers with large cross sections
-
・ Dam
・ Large machine foundation
・ Underground and aboveground tanks
- 3. Concrete that is built in hot weather
- 4. Structures requiring particular attention to cracking and strength
