On November 23rd the 3rd International Conference ‘Gas Vessels. Full Year 2017 Results’ brought together key market players, final products manufacturers, and government officials in the Baltschug Kempinski Hotel (Moscow).
They paid a lot of attention to the vessels safety issues both at manufacturing facilities and during household operations. The general focus of the conference indicates the beginning of the market shift to composite vessels that are safer because they do not fragment upon rupture, and have better figure of merit compared to conventional 1 and 2 types’ vessels.
This topic relevance is also proved by the overwhelming number of presentations in some or other way concerned with composite materials used for either vessel shell or vessel liner.
The presentations made at the conference covered mainly the benefits of various-purpose composite vessels and included all main types of reinforcing fibers used for polymer composites.
The delegate of Korea-based Huosung Corporation talked about the prospects for carbon fiber application and pointed out that carbon fiber can be combined with aramid, basalt, and glass fibers, depending on the specifics.
Elena Monakhova, Chief Technical Projects Specialist for DPO Plastik spoke about glass and carbon fiber reinforced vessels, focusing on the benefits of composite vessels over 1 and 2 types ones. The same composite materials were covered in the presentation of Daria Berndt, who represented Hexagonxperion.
Sergey Chistikov, the General Director of Russian Cylinders, talked about the best practices in carbon and basalt fiber application. Produced by his company, mobile gas storages allow maximum volumes of compressed gas to transport, in comparison with similar systems.
The mobile gas system is based on two types of metal composite vessels either with polymer shell reinforced with basalt roving or carbon composite shell. The vessels figure of merit or a weight-to-capacity ratio, varies in the range of 0.4-0.6, depending on the applied reinforcing component.
The company product range offers different fibers reinforced vessels in different price segments, this aspect makes it possible to meet demand on pressure vessels for gas transportation.
The participants also discussed the lack of necessary regulatory documents making standards in composite vessels design and construction, and also in their operating conditions, such as the control over worn-out vessels and ancillary items timely replacement.
The conference participants concurred that it is important to take comprehensive measures in order to establish a contemporary regulatory framework. However, this issue can be resolved only in the context of a dialog between composite industry professionals, gas vessels market players and government officials.
