Net-formed overall reinforcing outer sleeve

The utility model belongs to overall reinforcing structures of complicated surface outer walls, and particularly relates to a surface net-formed overall reinforcing outer sleeve. Two steel sleeve semi-rings sleeve a high-pressure device in a butt-jointed manner, an overall reinforcing steel sleeve hot stamped by a mould is closely fitted with the outer wall of the high-pressure device, the shape of the mould is consistent with that of the high-pressure device, the two semi-rings are welded together by a butt-jointed seam, the high-pressure device is overall reinforced, the high pressure of an inner cavity of the high-pressure device is borne in hot commissioning, the high-pressure device cannot be damaged, and the strength and the rigidity of the whole high-pressure device can be remarkably improved by the aid of a saddle-type overall reinforcing steel sleeve. After a product is formed, an inner profile does not need to be machined, the process is simple, precision is high, and the overall strength and the ri
