Design & Martial
Interclamps are made from malleable iron manufactured in conformance with BS EN 1562:2012, a dependable and well proven material for this type of product. The fittings are hot-dipped galvanised to BS EN ISO 1461:2009, giving a durable corrosion resistant finished surface for extended life. A secondary additional coating is then applied over the top of the galvanising, to enhance further the corrosion protection and to offer a premium quality, aesthetically pleasing appearance. High quality stainless steel setscrews, which are specified in the optimal size for each size range, contribute significantly to the high structural integrity of the Interclamp fitting. To obtain optimal setscrew slip loads,the setscrew should be tightened to 40Nm, for which a ratchet wrench may be necessary.
Six* different size ranges of Interclamp are available as shown in the table, hence a suitable size can be selected for any particular application. Interclamps are easily identified by a type number of each design eg. 125 followed by a size code eg. D48, the latter part of which corresponds with the approximate outside diameter of the tube to be used (48.3mm = 1 ½" nominal bore in this case). Hence a 90° elbow suitable for an 1 ½" nominal bore tube in this example would be denoted as a 125-D48.
