Haat Incinerators India P. Ltd. is a company which is dedicated to the concept of a “clean environment” through providing “engineering solutions for burning issues”.  To achieve these objectives, we need:

•             Good design capability

•             Committed staff with certain attributes like correct attitude, imagination, inventiveness and hard work

•             Good infrastructure

•             Quality control at all times of manufacturing

In this blog, we wish to highlight some of the quality checks that we carry out during various incinerator production stages to ensure conformity to certain standards so that the incinerator performs at the customer`s end and has a reasonably long service life.

1.            Quality of welding: Each weld is subjected to visual examination for any defects such as, undercut, spatter, lack of fusion, cracks, pinholes etc. thru a Non Destructive DP test.

Where there is a critical part and the weld joint should have no defect at all, radiography is carried out.  The customer may specify 10% radiography, but very often we carry out more than 50%.

2.            Quality of piping: As soon as a particular length of piping is given a root run, the weld penetration is first checked by a DP test and once it passes this test, further welding is allowed to be carried out. After completion of welding, the entire pipe length is subjected to a “hydrostatic pressure test”, the parameters for which are already available in the project contract.

3.            Quality of preparation: The sub-assemblies which are fabricated and ready for the next stage of manufacture, are blasted in a specially constructed room, using steel grits. The depth of blasted profile is checked from to time, using a Profile Depth Gauge, to ensure conformity to SA 2 ½.

4.            Quality of painting: The coating may be a 2 layer or 3 layer process, but each layer has to have certain minimum thickness of coating. For this purpose, the Wet Film Thickness (WFT) is first measured with a special gauge and after meeting the thickness requirement, further layers are allowed to be deposited. Even the final layer is subjected to WFT and once the paint has become dry, Dry Film Thickness (DFT) is checked with a coating thickness meter.

Not surprisingly, our incinerator systems are performing well globally and have provided good service to users over many years. The emissions coming out of Haat incinerators are well within required local standards.
