Complete Sets of China Metal Tube Online Automatic Detection Equipment Replacing Imported Products
From Laser Institute of Shandong Academy of Sciences, reporters learned that their independent developed complete sets of metal tube online automatic detectio succeeded in the application. This equipment has not only broken foreign non-destructive testing equipment monopoly in China, but also directly increased more than 5 billion yuan economic benefit each year for enterprises that use this equipment.
China, the largest producer of metal in the world has more than 2,000 large and small-scale metal tube enterprises, only the output is about 100 million tons. In the absence of sophisticated detection technology, products are difficult to enter the international market. Meanwhile, the testing equipments that import from abroad are expensive, and also can't adapt to China's metal tube.
In order to solve the problem of metal tube online automatic detection, Laser Institute of Shandong Academy of Sciences launched the technological breakthrough. Through making use of through-type, point vortex, flooding, water film ultrasonic and other detection technology, they achieved the online detection on the surface and internal defects of metal tube in real time. This complete set equipment of automatic detection can analyze the reason why the metal tube doesn't work, and remind producers to adjust the production equipment in time, it also can pick up the damaged metal tube away from the production line, which has greatly increased the rate of quality products. The equipment can test the metal tubes with 5mm to 1200mm diameter, covering all specifications of domestic metal tube at present, so it is the metal tube online automatic detection equipment with most widely range of detection diameter and highest detection accuracy currently in China, and it has reached the international advanced level.
The institute said that this equipment can replace imported products, and the price of the equipment with same index is only one half of the imported equipment. According to incomplete statistics, the equipment has been promoted to more than 10 provinces such as Shandong, Jiangsu, Hebei and so on, nearly 200 sets equipment are used by more than 120 enterprises such as Baosteel, Baotou Steel, Panzhihua Iron and others, it has newly increased more than 5 billion yuan for these enterprises economic benefit, and also saved about 100 million yuan raw materials and energy.
According to industry experts, the successful application of metal tube online automatic detection technology has increased the quality of domestic metal tube and enlarged the applications in high-end fields such as nuclear power tube, high-pressure boiler tube, which will make significant economic and social benefits.

How exactly do you go about biasing a tube amp for two EL-34 tubes?
We have a Genz Benz El Diablo 60c amp, and we're putting in a couple EL-34 power tubes, and a set of three JJ 12AX7s, and we need toi bias them too. Anyway, we just need to know how to do it.
Generally , just the power tubes (EL34's) would require biasing - THAT has to do with adjusting voltage , where 12AX7's are a preamp tube and are pretty much plug and play. If you never did biasing before (and it sounds like you haven't) , don't mess with it , take the thing to a local shop and and experienced tech that has done it before.
