Performance and Guarantee Test and Acceptance of the System by purchaser

Dynamic load tests while maintaining safe process conditions and without endangering the equipment. All tests will be performed with the system in automatic mode:

a) Drop 50 per cent of maximum load capability from approximately full load at a rate of 10 per cent per minute.

b) Drop load from full rated output to the lowest load runback limit, at a rate corresponding to the fastest runback rate.

c) Pick up 50 per cent of the maximum load capability from approximately 50 per cent load at a rate of 10 per cent per minute.

During transient conditions causing deviation of process variables, the control system furnished under this specification shall not permit deviations which exceed those permitted by the manufactures of the controlled process equipment, for load demand changes upto 10 percent of rated full load capability per minute. Controlled process variables shall return to normal in a stable manner and without any loop interactions or cycling of generation when generation matches unit load demand.

2.19 Painting

The plant shall be painted before dispatch to Site. Painting specifications are furnished hereunder. To facilitate correct re-assembly of gearing, turbines, vessels, etc. at Site, colour identification shall be applied to each plant piece and its associated equipment of the plant and parts, within a series or train of similar pieces.

Preparation of surfaces

Prior to treatment, the metal surface shall be cleaned of dirt and grease, layer of rust, weld spatter etc. These shall be removed by pickling, power tool chipping, de-scaling, sanding, wire brushing or grinding. For wire brush cleaning, the wire

brush shall be applied carefully over the surface in vertical and horizontal direction.

For motor driven cleaning, brush, tube cleaner and disk sander shall be used. The work shall be done in such a way that the brush is applied over two times on each portion of the object to be treated. Either feather type or gear type cutter shall be attached to the tube cleaner. Application of the cutter shall be done carefully in the longitudinal direction except for unavoidable cases.

Recommended types of paints

Painting for Machinery, Equipment of the Plant, and Piping shall be applied as follows:

Primary coat Red Oxide Paint

Under Coat Phallic Anhydride Paint

Finish Coat Phallic Anhydride Paint

Corrosion protection (wherever required) Pitch based resinous Galvanized Steel

Internal surface of vessels, tanks, heat exchangers, etc.

Machine finished surface where performance will be adversely affected if painted. In the case of layered painting, the next painting shall be applied after cleaning the surface of the previous layer and after a gap of minimum 8 hours drying.

The coating thickness of each layer shall be uniform. Notices, name plates, lettering, gauges, sight glasses and similar items shall not be painted over and shall be protected during painting by the application of masking tape and cleaned after painting is over.

Painted Film Thickness

The thickness of finish painted film shall be even. The standard thickness values to be measured by net micro-thickness gauge shall be as follows:

Red Oxide paint Over 125 (4 coat basis) Phallic acid resin paints Over 150 (4 coat basis) 2.20 Packing

All equipment of the Plant shall be packed as necessary to provide adequate protection during delivery to Site.

The Goods shall be fully protected from weather and corrosion by suitable paint, preserving grease or wax paper together with silica-gel or any other protective hygroscopic material, as may be required.

The packing cases shall be lined internally with tarred paper or polythene and the lids lined internally with roofing paper.

The packing cases shall be of substantial timber construction screwed or nailed

together and shall be provided with skids preventing direct contact with the ground or floor, and permitting the use of fork-lift trucks or slinging for lifting by cranes.

Small items shall be gathered together and transported in packing cases.
