3 MANUFACTURING METHOD FOR GENERALLY CYLINDRICAL THREE-DIMENSIONAL CONFORMAL LINERS

摘要

A method for manufacturing a liner, the method comprising: tubular having an upper cylindrical edge, a lower cylindrical edge, and welded joints or seams extending from the upper cylindrical edge to the lower cylindrical edge; Forming a body portion of the; Elongating the tubular body near an edge of the upper cylinder and welding an upper liner sheet portion along the elongated upper cylindrical edge, the upper liner sheet portion having a fit welded thereto; And extending the tubular body near the edge of the lower column, and welding a portion of the lower liner sheet along the edge of the elongated lower column. Welding between the tubular body portion and the upper liner sheet portion may be affected by the internally infiltrating surfaces of each portion in contact. Similarly, the welding between the tubular body portion and the lower liner sheet portion may be affected by the internally infiltrating surfaces of each portion in contact.
