Sa1 SP-7

Power Tool Power Tool cleaning

Very thorough scraping and wire-brushing-machine brushing-grinding-etc. Surface preparation as for St2, but much more thoroughly. After removal of dust, the surface shall have a pronounced metallic sheen.

St3 SP-3

Hand Tool Hand Tool Cleaning

Hand tool cleaning is a method of preparing steel surface by the use of non-power hand tools. Hand tool cleaning removes all loosed mill scale, loose rust loose paint, and other loose detrimental foreign matter. It is not intended that adherent mill scale, rust and paint be removed by this process. Mill scale, rust and paint are considered adherent if they cannot be removed by lining with a dull putty knife.

St2 SP-2

Solvent Solvent Cleaning Solvent cleaning is a method for removing all visible oil, grease, soil, drawing and cutting compounds and other soluble contaminants from steel surfaces. It is intended that solvent cleaning be used prior to the application of paint and in conjunction with surface preparation methods specified for the removal of rust, mill scale or paint.

(b) When the surface to be prepared is wet, preparation shall not be carried out. (c) When the relative humidity is 85% or higher, surface preparation shall not, in principle, be carried out. (d) When surface preparation is carried out during the night or in dark locations (Inside of tanks, etc.), use lighting equipment by means of which the extent of rust removal from the surface can be seen. (e) When blast cleaning is to be carried out at the job site, appropriate protective measures shall be taken to ensure prevention of adverse effect of dust on adjacent work or environmental pollution in the surrounding area. 4.1.3 Treatment after surface preparation After the completion of surface preparation, the following confirmation and work shall be carried out and the subsequent painting shall also be started promptly. (1) When rusting occurs after completion of surface preparation and before painting, carry out surface preparation again using appropriate methods. (2) The painting surface shall be fully cleaned of mill scale, rust and other dust accumulated on the surface due to the surface preparation work. (3) The painting surfaces (cleaning of which has also been completed) shall be kept clean in such a way as to prevent the adherence of grease, oil, dust and other detrimental matters until the painting work is started. 4.2 Execution of Painting Work 4.2.1 Protection Vendor shall fully protect all equipment, piping, walls, floors and other surfaces from damage and contamination, and shall provide the necessary protection required to fully protect all surfaces from dust, paint droppings, paint mist, other contaminants during the execution of painting work.

Project: ME1801 Client : Thermax Limited Location: Chinchwad (Pune) Document: ANNEXURE-T9 -Distributor Performance test (FAT Test)


ANNEXURE-T9 -Distributor Performance test (FAT Test)

All Liquid distributors/redistributors shall be water tested in the vendor's shop by the following Procedure at 50%, 100% and 120% of the design case 1 (Refer “Annexure T5 – Process data Sheet”) for all columns.

The vendor shall certify to the purchaser at the time of bidding that they believe their equipment can meet the testing requirements listed below:

a. If the distributor contains a predistributor, it shall be tested first to ensure that it has a

CV (coefficient of variation) of 5 or less at the design flow rate. Each pour in the predistributor shall be tested. The CV(coefficient of variation) is defined as the ratio of the standard deviation to the sample mean, expressed as a percent.

b. The distributor/redistributor itself shall be tested and the CV determined. To determine

the CV (coefficient of variation), at least 30 pour points or at least 10% of the pour points (whichever is higher) shall be randomly selected and tested. If the CV specified below cannot be met, the vendor will correct the problem at its expense.

c. The average flow rate per pour points for any grouping of 10 of the tested pour points form a single area should differ by no more than 5% from the average for the group being tested.

d. Thermax engineer will witness this test and based on the approval of same, vendor can dispatch the distributor to site.
