I have always been puzzled by the notion that tubes have seems. A seem would be visible on both sides of the material being joined. The inside of a tube is uniform all over. There are joins in the moulds which leave lines on the outside of the tube, sure but no seems in the tube. I suspect that if a tube fails along one of those joins, it might be to do with different cure rates across the join. I'm not an expert on this (seems neither were those who made those tubes) so take this FWIW.
