An electroweldable branch fitting for high diameter pipes comprises at least a first collar (20, 20′) provided with a predetermined radius of curvature (R), wherein the collar (20, 20′) identifies on opposite sides a concave surface (21) and a convex surface (22), further comprising at least one first electrical wire winding (23) associated with the concave surface (21) of the collar (20, 20′) and carrying one first pair of electrical terminals (24), arranged on the convex surface (22) of the collar (20, 20′) for applying an electric current adapted to cause the electrofusion of the collar (20, 20′), wherein the concave surface (21) of the collar (20, 20′) is continuous, i.e. not perforated, and wherein the first electrical wire winding (23) is uniformly distributed on the concave surface (21) at least in the central part thereof, the collar (20, 20′) being provided with a branch sleeve (30), centrally on the convex surface (22), for the connection to a branch pipe, the branch sleeve identifying a blind hole (32) having a bottom wall (32) consisting of the wall of the collar (20, 20′).
1) Electroweldable branch fitting for high diameter pipes comprising at least a first collar (20, 20′) provided with a predetermined radius of curvature (R), wherein the collar (20, 20′) identifies on opposite sides a concave surface (21) and a convex surface (22), the branch fitting (10, 10′) also comprising at least one first electrical wire winding (23) associated with the concave surface (21) of the collar (20, 20′) and carrying one first pair of electrical terminals (24), arranged on the convex surface (22) of the collar (20, 20′) for applying an electric current adapted to cause the electrofusion of the collar (20, 20′), characterized in that the concave surface (21) of the collar (20, 20′) is continuous, i.e. not perforated, and in that said first electrical wire winding (23) is uniformly distributed on the concave surface (21) at least in the central part thereof, said collar (20, 20′) being provided with a branch sleeve (30), centrally on the convex surface (22), for the connection to a branch pipe, the branch sleeve (30) identifying a blind hole (31) having a bottom wall (32) consisting of the wall of the collar (20, 20′).
