Steam traps Manifolds and insulation jackets
8
Installation Once the manifold has been installed, the jacket can be fitted. The jacket is a one piece construction and there is no need to remove any pipework or handwheels to fit it. The jacket can be fitted quickly and easily by following this procedure. IJ-MSC Place jacket on the right hand side of manifold up to mounting studs so that continuous velcro strip is on outside face of jacket. Wrap jacket around uppermost pair of valves by passing flaps between pipework and valve bonnets/handwheels. Pass horizontal uninsulated velcro flap behind manifold and fasten on continuous strip on the other side. Now position and fix large flap between each pair of valves. Adjust any flaps as necessary. The label should be positioned between the uppermost pair of valves and all vertical flaps should point downwards. Finally the upper and lower drawcords should be pulled tightly around the DN40 pipes to close any air gaps. When fitted the jacket should be a tight fit. The flaps and drawcords should be fitted tightly to minimise any gaps that would allow air to flow through or allow the ingress of water. IJ-MSC-H Place jacket on the left hand side of the manifold up to mounting studs so that the buckles on are on the outside face of the jacket. Wrap jacket around uppermost pair of valves by passing flaps between pipework and valve bonnets/handwheels. Pass strap behind manifold and through buckle on other side. Now position and fix large flap as necessary. The label should be positioned between the uppermost pair of valves and all straps should point downwards after fastening. Finally the upper and lower drawcords should be pulled tightly around the DN40 pipes to close any air gaps. When fitted the jacket should be a tight fit. The straps and drawcords should be fitted tightly to minimise any gaps that would allow air to flow through or allow the ingress of water. However, be careful when pulling straps tight that you do not inadvertently open up gaps in other places. Important note: Both the inner/outer face and insulation are made with a bonded aluminium foil. At a temperature of 120 °C the adhesive bonding the aluminium will start to degrade and delamination of the foil will occur at 150-170 °C. Scorching of the internal fabric may occur at 150 °C. Neither of these reactions will impair the performance. Removal Before removing the jacket, check if the manifold is in service. If it is, then the metal surface will be hot enough to burn and suitable protective clothing (e.g. gloves) should be worn. If it is necessary to access any valve, then the whole jacket does not need to be removed. Handling When the jacket is new, the insulation material is fully enclosed within the inner and outer face and retained by the stitching. In this condition for handling no special protective clothing is required. However, if the inner and outer faces become unstitched or damaged so as to expose the insulation material then suitable protective clothing (e.g. gloves, safety glasses, face mask and overalls) should be worn.
