Stainless steel tube manufactured using TIG welding

view enables a cross section view of the inspected material. Enabling the high-speed scan function will give the user 50 readings per second. Five user-selected operating modes are included: coating on, coating off, thru coat and coating only. All measurements are temperature compensated. Minimum coating thickness is 0.0127mm, allowing the gauge to precisely measure thin coatings with the advanced waveform analysis technique. A large backlit graphic LCD features easy- to-read fonts, graphics and display codes which show all critical settings. CT-Gage features include auto probe zero, auto probe recognition, auto temperature compensation, and a standalone coating only mode. The standard pulse-echo and thru-paint echo-echo modes are standard features. The CT-Gauge data-logging model adds built-in memory, with an RS-232 output for transferring data to a printer or PC. Data files can be user-set for a ‘grid type’ structure (data formatted in rows and columns) or a ‘sequential’ file (all data appears in a single column).

Quality Stainless, India, is a manufacturer of welded stainless steel tube and pipe, using its own cold rolled stainless steel coils. The company’s two product divisions – tube/ pipe and coil/strip – are ISO 9001:2000 and AD-2000 W2 certified under Lloyds Register and TUV. The products are manufactured as per DIN, EN, ASTM, JIS, SS and ISI standards. The company’s product range includes sizes from ½" to 4" OD, and ½" to 6" NB, with thicknesses from 0.5mm to 4mm, and grades including 304/304L, 316/316L/316ti, 321, 439/409,430, low Ni grades and duplex. Testing facilities include eddy current (Dr Foerster, Germany), hydro-testers, UTM, hardness test, inter-granular corrosion, microstructure and other necessary mechanical tests. The company has a large customer base in industries such as heat exchanger, pressure vessels, food processing and beverage equipment, the dairy industry, power turbines, chemical and pharmaceutical,

automobile, oil and gas, and other general engineering industries.

Not only do both models measure coating and wall thickness quickly and accurately, from only one side, but they automatically measure and eliminate any coating from wall thickness measurements. This allows users to locate the finest corrosion and pitting- without removing the coating. It is possible to create and store 64 custom setups for common testing applications.
