To provide a winding type pressure vessel allowing visual examination and non-destructive inspection of a cylindrical inner cylinder in regard to a winding type pressure vessel wound with a high strength wire applied with tension on an outer circumference face of the cylindrical inner cylinder, and equipped with a cooling water passage for preventing superheating of the cylindrical inner cylinder.
The winding type pressure vessel for carrying out high temperature high pressure treatment of an object to be treated, is equipped with: the cylindrical inner cylinder 2; a high strength wire winding layer 3 comprised by winding the high strength wire applied with tension on the outer circumference face of the cylindrical inner cylinder 2; and the cooling water passage 5 for preventing superheating of the cylindrical inner cylinder 1. A cylindrical liner 4 having a recessed part for the cooling water passage in its outer circumference part is detachably fitted in the cylindrical inner cylinder 2, and the cooling water passage 5 is formed between an inner circumference face of the cylindrical inner cylinder 2 and the recessed part for the cooling water passage.
