Zusammenfassung:PURPOSE: To obtain a long cylinder with excellent corrosion resistance and wear resistance without receiving restriction of manufacturing facilities. CONSTITUTION: At least two cylinder 10 and 11 are connected with each other by fitting, inserting and screwing and outer surface parts of end parts of the cylinders are welded and fixed with a bead 4. Screwing is performed by fitting and inserting the end part 10a of the cylinder 10 into the large diameter cylindrical part 11a of the end part of another cylinder 11 to bring the apex face of the cylinder into press contact with the bottom face of the large diameter cylindrical part 11a. A long cylinder with excellent bonding strength and adhesiveness can be obtd. at a low cost and manufacturing of a long cylinder which has been conventionally hardly performed becomes possible.
