Ultra-large pressure vessels utilizing superior forging techniques
Among the facilities in oil refineries, our products are used in processes involving extremely harsh conditions. These include sulfur removal and conversion of heavy oil to lighter products through catalytic reactions under high temperature and high pressure, with addition of hydrogen.
There are many varieties of crude oil. Since heavy oil solidifies when cooled, it can only be cracked under high temperature and high pressure, requiring extremely strong pressure vessels to refine it. Only pressure vessels with thick walls can withstand such conditions.
One of our strengths is the manufacture of sturdy, thick-walled pressure vessels for processing such heavy oil. In recent years we have also developed stronger alloys to create pressure vessels capable of withstanding high temperature and high pressure even with thinner walls.
Our operations feature consistent production and quality assurance systems covering every step from materials manufacturing to assembly welding.
