Zusammenfassung:A RISER ASSEMBLY AND METHOD OF FORMING WHERE THE RISER ASSEMBLY IS MADE UP OF TUBULAR MEMBERS JOINED TOGETHER. A METAL SPRAY PROCESS APPLIES A LAYER OF CLADDING ONTO ENDS OF THE TUBULAR MEMBERS AND THE ENDS ARE THREADED TO FORM RESPECTIVE BOX AND PIN CONFIGURATIONS. GROOVES ARE PROVIDED ONTO THE SURFACE OF THE TUBULAR MEMBERS BENEATH WHERE THE METAL SPRAY IS APPLIED FOR ENHANCING ADHESION OF THE CLADDING AND TUBULAR MEMBERS. THE LAYER OF CLADDING PROVIDES SUFFICIENT MATERIAL SO THAT THREADS MAY BE SELECTIVELY FORMED ON THE OUTER OR THE INNER SURFACE OF THE TUBULAR MEMBERS.
