Abstract:
A substantially continuous method of manufacture of a laminated tubular body. The method includes the steps of drawing opposite longitudinal edges of a strip of sheet material (6) into close proximity, joining the longitudinal edges to form an outer tubular body, extruding a hollow tubular lining member (5) from an extrusion die (3), heating the lining member, and expanding the lining member within the outer tubular body to form a substantially continuous lining in intimate contact with an inner surface thereof. The lining member (5) is formed from thermoplastics material and is heated to a temperature sufficient to form a thermoplastics weld bonding the lining to the inner surface of the outer tubular body.
