We experience considerable trouble with the spherical pattern pipe unions. We agree with all you say in regard to the disadvantages of the conical type, particularly with regard to the need for absolute lineability. Providing lineability is assured, the joint can be re-made time after time without leakage resulting. (Handwritten signature) | ||
