6 Cryogenic Tank Manufacturer

Cryogenic liquids exist at extremely low temperatures which is why specialized equipment is required for their transportation and storage. Contrary to popular belief, it’s not just possible to store cryogenic liquids in a standard container.

Doing so would make it impossible to handle them and would also present health and safety risks to those who work with them. Cryogenic tanks are built for this express purpose.

They’re manufactured with durable materials that are able to withstand such low temperatures. Additional precautions are also built into the equipment so as to reduce any chances of leakage.

What is a cryogenic tank?

Cryogenic tanks are the containers that are used to store cryogenic liquids such as liquid nitrogen, helium, argon, etc. Cryogenic tanks are also utilized for storing gases like liquefied natural gas and nitrous oxide at higher temperatures.

It’s vital for these tanks to be thermally insulated so as to maintain the low temperatures. This is achieved through the use of a vacuum jacket. It’s vital that this component be designed and manufactured to a high specification that follows established international design codes. 

Cryogenic tanks can be of several different kinds. Static or fixed tanks are those that are used in a fixed location, such as a cryogenic processing facility. Static tanks also include the small mobile tanks that are mounted on wheels for use in labs and workshops. 

These small cryogenic tanks are also known as pressure vessels. There are non-pressurised open neck vessels called Dewar flasks available as well for use in scenarios where direct access to the cryogenic liquid is required.

It’s possible to repair cryogenic tanks but it’s not a job that just about anyone can do. Any repairs or modifications to such tanks should be carried out by a skilled repairer who performs the job in line with the design codes to which the tank was manufactured. 

They also need to be mindful of the prevailing regulations and legislation. 

Any and all repairs or modifications carried out need to be documented so that records can be kept for as long as the tank is in service.

Where cryogenic tanks fit in the cryogenic treatment process

Cryogenic tanks are integral to the entire cryogenic treatment process. Without them, it would not be possible to transport and store cryogenic liquids. So it can be said that the cryogenic treatment process wouldn’t be possible without these tanks. 

Their efficacy isn’t just limited to the storage and transport of the cryogenic materials. These tanks also play an important role in the deep cryogenic treatment process, where metals and plastics are kept submerged in the cryogenic liquids for up to 24 hours. 

As previously discussed, it’s not possible to do this with a conventional tank. There would be too many factors at play that would disrupt the treatment process. That’s what makes cryogenic tanks so vital to the entire process. Without them, deep cryogenic treatment can’t take place.

State of the industry: cryogenic tanks

There’s a fair bit of legislation that governs the industry’s use of cryogenic tanks. They have to be operated and maintained in a manner that’s in compliance of these regulations. 

Only designated competent persons are to maintain and manage the cryogenic tanks. The industry abides by these regulations. As such, static tanks are put through inspections at regular intervals. Routine maintenance and periodic formal examination is also carried out. 

The maintenance and inspection regime has to be created so that it can be ensured that the tank is in a position to allow safe operation at all periods of time between the formal examinations. 

Periodic inspection and testing is also required for transportable tanks and this can only be performed by an inspection body. These inspections and examinations have to be documented and the records have to be retained for the life of the tank. 

There’s a duty of care that the industry needs to abide by when they own or use cryogenic tanks. Responsible gas suppliers will only fill a cryogenic tank once they’re satisfied that it’s safe to do so.
