For producing the method for resistance tank, including the starting stage, closing metalware is formed in the starting stage, followed by second stage, the wall of the vessel described in second stage is subjected to mechanical pretension on axially and radially direction and handles until predetermined value.This mechanical treatment includes the stage that wherein tank is closed in the mould inside with suitably larger size.Then tank is inserted the liquid into, and this liquid is pressurized until the wall of tank expands and extends at the point that they intersect with the inner surface of mold.Then, by the external coated with one or more layers composite material of tank, to complete the structure of tank, final self-tightening is performed to tank and is handled.The type of steel to be used is AISI 304, it is therefore preferable to its more solderable AISI 304L form. |
