... used in combination. The technique known as batch filming uses a "pill" of concentrated chemical contained between two pipeline pigs; a lead pig and a filming pig (referred to as a pig "train"). In theory, the filming pig allows a small volume of chemical to continuously bypass the rear of the filming...

... that there is a difference between the conditions created in each sample holder of the equipment although it cannot be quantified. Additionally, there also appears to be a difference between the environmental conditions present for each batch. Coatings applied to different substrates have been investigated in the erosion...

.... This paper discusses several case histories where the coating manufacturer, by their errors, caused a coating failure. Among the topics discussed are quality control methods, raw material availability and supply issues, color matching and batch controls, inventory management and product shelf life, excess...

... specimens, weight loss was measured to calculate corrosion rates. The first batch of tests at 80 °C [176 °F] and 85 percent relative humidity for 181 days showed that the corrosion rates of the specimens subjected to dripping were in the range of 20–50 nm/yr [7.9 × 10-7–2.0 × 10-6 in/yr], similar...

... the corrosion component with corrosion inhibitors minimizes the damage, and that continuous application of the inhibitor is more beneficial than batch application. This paper follows laboratory development and field testing of a batch applied corrosion inhibitor designed to have added benefit for this task...

... mentioned rules (e.g., easy visualization of the amount of paint applied, durability forecast and so on). As a result of the cooperation, the ADFT concept has been implemented on a wider scale. The concept is based on Gaussian approximation of the DFT measurements'' batch. Two different values can thus...

The first short coming being a very limited performance lifespan, and the other is inadequate chemical coverage as well as treatment...
