This is a restrained joint system used for joining plain end pipes which consists of overlapping layers of fiberglass reinforcement thoroughly impregnated with the resin to achieve the specified width and thickness. It provides continuity in both hoop and axial directions. It is generally preferred for field adjustments and repair work where no other joint systems can be used. This joint is also called butt and strap joint and it results in high strength and requires skilled labour. Fig-9 shows the lamination joint for small diameters where there is no possibility to access the inside of the pipe to do the internal lamination. Fig-10 shows the lamination for nominal size 900mm and above.
