With superior alloy steel, pressure containing parts have better strength and impact toughness.

Combined seal rings are used on side door for stronger sealing performance.

Two flanks of the chamber are orthodrome-shaped,and the parts around are arc-shaped.This kind of structure can decrease the stress peak value of the shell.
