S.U.N. Engineering’s unique pipeline sphere manufacturing process allows the Super Sphere to be made without a seam. This unique process eliminates concern over seam splitting or delaminating and also permits valve bodies to be firmly embedded in the wall of the pipeline sphere to prevent leakage from around the valve. In addition, Super Spheres have more consistent wall thicknesses that will offer truer diameters, uniform wear and constant wall contact in prover and pipeline operation.
