Large-diameter flange is one of the flanges. It is commonly used and promoted in the mechanical industry, chemical industry, wind power industry, and sewage treatment industry. It is well received and favored by users. The large-diameter flange is widely used and its production process is divided into In rolling and forging, the only big thing is the rolling. Material is carbon steel, stainless steel and alloy steel.
Because the color and quality of the large-diameter flange are irrelevant, and the material of the flange is also irrelevant, the color of the flange surface is only the color of anti-rust oil, and is not the color of the material of the product itself. However, from the large-diameter flange surface color can also determine the product's production date, if the date is long, anti-rust oil penetrates into the product, it will look old and not so fresh in appearance, but this does not indicate the quality of the product has a problem. On the contrary, some of the old goods produced in the past are of better quality than the current ones. Like many other industries, the quality of products is generally inferior to the past, because people always put profits first. This will sacrifice product quality.
Large-diameter flanges nowadays are both inferior in terms of workmanship and size, and this is an undeniable reality because of market conditions. This is the case for the flange market and even for the entire industry. The goods market is not good, and it is hoped that manufacturers and users engaged in flange production will work together to improve this unsatisfactory status quo.
