Sanitation and air conditioning works
In new construction, we install insert sleeves, mark out, thread piping, and process pipes. We also measure air volume until the final test.
Pipe freezing work
When repairing existing piping, replacing valves, cutting or expanding piping, etc., when there is no valve upstream of the work area, the valve's location is unknown, or the valve is unusable and water cannot be stopped, the pipes at the work area are frozen with liquid nitrogen or liquefied carbon dioxide to stop water flow. Water etc. in the pipes is partially removed, making the work quick and reliable.
Equipment Dismantling
We can dismantle and remove various pipes, air conditioning equipment, and ducts.
When pipes freeze, we can attach valves and remove unnecessary pipes.
