Hate Hydraulic Adhesion Tester

The HATE Mark VII coating adhesion testers offer the coating industry new capabilities, from the lab technician and paint chemist to the field inspector and corrosion engineer. The adhesion strength specified can now be proved to have been achieved - even on and in, tubulars in the most awkward positions!

The design of the HATE tester is simple. Load is applied through the center of the dolly by a hydraulic piston and pin (Fig. 1). The hemispherical tip of the pin ensures a point loading of the force. Consequently, the force reacted in the dolly is a uniform, purely tensile load. The diameter of the piston bore is sized so that the area of the bore is equal to the net area of the dolly. Therefore, the pressure reacted by the dolly is the same as the pressure in the bore which is transmitted directly to a pressure gauge. This area ratio of 1:1 and a direct reading from a pressure gauge ensures repeatable accuracy. The accuracy of the HATE tester is ± 1%, this comparing to an accuracy of ± 10% for mechanical adhesion testers.

Technical Data
Model Pressure Rating
PA-8735: Dual Scale 3,500 psi /250 MPa Other pressure ratings are available on request. Working range is 75% of Full Scale Deflection (F.S.D.)
Accuracy: All models have an accuracy of ± 1% of F.S.D.
Tolerances: The internal diameters of the piston bore and dolly and the dolly outside diameter are machined to a tolerance of ±1 thousandth of an inch.

 

Safely

top

Your HATE adhesion tester is intrinsically safe. By turning the handle clockwise, a finely threaded plunger decreases volume, and increases the hydraulic pressure on the oil within the body. As oil is an incompressible fluid, any leakage will cause a dramatic drop in pressure. Your HATE tester requires only 0.5 cubic centimeters to be lost for the pressure to drop from 2,000 psi to 0 psi.

With a mechanical system, as the spring stores a large amount of energy, a pull-off results in a sudden release of this energy causing a loud bang and the tester to jump. Because your HATE tester operates hydraulically, only a small amount of energy is stored, therefore a pull-off is a lot quieter.
