Jul 13, 2017 · 1.- Prepare the bevel leaving two projections (2-3 mm) of clad in the root of both pipes. 2.- Weld the two projections of clad with WPS appropriate for the type of clad. 3.- VT to the clad welding, if you have access and equipment check with inner borescope. 4.- Finish welding with appropriate WPS for pipe material. 5.- Rt the weld Cold Applied Tape Coating System Field Joint (10.16 cm) wide shall be centered, smoothed, and coat the entire surface of the raised girth weld. 5.0 JOINT COATING APPLICATION 5.1 The cold applied joint wrap tape coating systems shall be applied under hand tension or using a hand-wrapping machine capable of maintaining even, constant tension across the width of the tape.
Pipe lengths (typically 12 meters) are coated in a pipe mill or coating plant, with each end left uncoated (bare steel cutback approx. 150200 mm on each end). These ends are then welded in the field. That weld (field joint) is then coated in the field setting. Pipe Protection Tape System - Pasco Specialty4. Weld beads shall be covered with one wrap or layer of tape prior to spiral wrapping. 5. Tape shall be spirally wrapped the length of the pipe using one half lap for double thickness or 1/2 overlap, depending on the individual installation. 6. When pipe is mill coated, tape must be used on the fittings and joints. To wrap a joint, first Pipes Repair - How To Repair Pipe Weld Joints
