Using a high strength chromium molybdenum alloy steel the ultra large pressure vessels are manufactured from hot rolled seamless pipe or forged seamless pipe. The hemispherical ends of the vessels are shaped by the forging process, the vessels are then heat treated and quenched.

Our ultra large cylinders are used predominantly in the following market sectors:

Naval

Oil and Gas

Transportation

Ground Storage

All our ultra large cylinder product range are manufactured to internationally recognised standards and codes. Third party inspection and approval is organised where applicable.

Naval Since the 1930's we have been supplying the UK Royal Navy with their high pressure gas storage requirements on submarine's and surface vessels. Other Navies from around the world are also taking advantage of our wealth of experience in this area. Applications range from backup breathing and weapons systems to nuclear reactor valve operating systems.

Oil and Gas Our high pressure seamless steel cylinders form an integral part of an oil rig's motion compensating system. We are the worlds' largest supplier of APV's (air pressure vessels) for floating offshore platforms.

Transportation Carriage of gases by road at high pressure is a very efficient method of transport. We have considerable experience in the supply of ultra large trailer cylinders for this purpose. We can also offer the complete package of the trailer with the cylinders.

Ground Storage We manufacture ultra large cylinders to provide a variety of static storage solutions for a diverse range of end applications. One of the more high profile uses of ground storage vessels is for the buffer storage of compressed natural gas (CNG). Our expertise at 400 bar working pressure on these systems is paramount.
