Degreasing prior to penetrant testing

November 2011

1- Introduction

Degreasing prior to PT is an ESSENTIAL and DECISIVE step to ensure a reliable inspection.

In fact, pollutants such as oils and fats, as any other material may clog discontinuities and prevent penetrant to do its job properly. As good as penetrant materials or inspectors are, nothing can be done against.

Waste-water treatment and Penetrant Testing

June 2011

I- Introduction

Rinsing/washing waters from PT process lines contain hydrocarbons, organic esters, surface active agents (surfactants), dyes and many other organic constituents.

French regulation, and probably regulation in other countries, state, among different requirements, that the effluents disposed of into sewers or rivers shall be clear and without any colour.

Hydrophilic emulsifiers waste water treatment installations and aerobic and anaerobic bacteria

September 2010
This technical paper is to deal with a recurrent trouble of Penetrant Testing lines: bad smelling from hydrophilic emulsifier tanks, especially when in warm or hot areas and that bad smelling of recycled water coming from a waste water treatment installation. We are to let you know of a very simple, cheap, efficient way to overcome most of the troubles.
