Description

Klamflex Couplings and Flange Adapters from HMA Flow & Industrial can be manufactured to suit almost any pipe outside diameter or flange drilling. Couplings and flange adaptors are manufactured to suit all standard pipe sizes. Where couplings are required for pipes in non-standard sizes and material, or where standard outside diameters are not exact, for example GRP and AC pipe, details of the actual pipe ODs and tolerance should be stated for consideration by Klamflex Pipe Couplings from HMA Flow & Industrial.

Design consideration should be given to the surface finish of pipe materials. By its very nature, the Klamflex coupling system relies upon good surface contact of the sealing rings. Consideration must be given to pipe-end preparation on pipes with naturally rough or uneven surface finish. Where surface dressing is required to remove weld beading, care must be taken not to overdress the pipe end, causing pitting or flat spots. In general, the recommendations of SABS 719-1971 and BS 534-1990 section 15 ensures a satisfactory surface finish.

Ovality, especially in larger diameter pipes, can frequently be rectified either by jacking out, if the ovality is severe, or by rounding out by selective bolt tightening to give a uniform annular gap. Care must be taken when jacking so that internal finish is in no way damaged. Pipes that have local stiffening near the ends are sometimes impossible to correct for ovality.
