On July 8, UMC Jining Science and Technology Park successfully produced the first sapphire crystal weighing 89.5 kg, which is the world's leading and the largest in China. This is another major project that Taiwan Lianhua Electronics Group has completed and put into operation since the construction of the LED high-end industrial cluster in Jining High-tech Zone last year. It highlights the strength of UMC Technology Park in the large-scale sapphire growth technology and also marks the Jining High-tech Zone. The complete industrial chain construction of LEDs from R&D to end products is gradually being built. Sapphire crystal is an extremely important basic material in the modern industry, especially in the microelectronics and optoelectronics industries. It is an upstream product in the LED new light source industry chain. Sapphire crystals are widely used in high-tech fields such as semiconductor, chemical, aerospace, aerospace, and defense industries, and have great social and economic benefits. The success of sapphire crystals has enabled Jining LED industry to have core material production capacity.
Stainless Steel Flange
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
