Pressure vessel technology is an important engineering scientific technology used widely in various industrial and high technologic fields.

The so-called high technologic pressured equipment includes large pressure storage tanks, ammonia synthetic reactors, urea synthetic reactors, petroleum hydrogenation reactors, large rocket shells, liquid hydrogen and oxygen pressure vessels, nuclear power station pressure vessels and so on.

“Filament-Composites structural pressure vessel technology” and “General-Steel structural pressure vessel technology” are the two main sorts of the contemporary pressure vessel technology in the world.A unique sort named “Steel-Composites structural pressure vessel technology” with several unique structural technologic system from low to high pressure application field, which has included China National Invention Prize and 18 Chinese and US patents in its system has been developed in China mainly by the author during past 30 years. This unique sort of pressure vessel technology has the excellent burst resistant and manufacturing cost reduced up to 40% etc. outstanding structural technologic characteristics. This will lead a radical reformation of pressure vessel technology in the world.

A typical technology of this unique sort named “flat steel ribbon cross-helically wound pressure vessel technology” used widely in China during past 30 years has involved officially in the ASME BPV Code as code number 2229 and 2269 for Section Ⅷ , Division 1 and 2 in 1997 respectively for manufacturing various important large industrial pressured equipment in the world with internal diameter up to 3.66 m by American Society of Mechanical Engineers as the first instance of significant technology from China.

The unique pressure vessel technology was assessed an advanced high technology in the world. This will surely open a new development prospect in designing, manufacturing and safe protective technical aspects of the 21 st century by using the special Steel-Composites structural technologic nature.
