They are upset and machinedto form a ball which is ground into the socket of the two pipes forming an element are held to their seats bymeans of a double clamp with a bolt in the center between thepipes. These bolts pass through cored holes in the header andhave nuts on the back, where they are protected from the smoke-box gases. Covered openings are provided ir. the smokebox togive access to these bolts from the outside. There are no softjoints of copper or composition employed anywhere in the de-sign. The design shown herewith is arranged for a superheat offrom ioo to 125 degs. and hence requires but one loop in eachsuperheating element. The same scheme, however, can be easilyarranged to give higher degrees of super-heat by having a double loop, or a four-pipesuperheating element, in each superheatingtube and a reduced number of connectionsto the header.
