When Yuxiang's isophthaloyl chloride unit is put into production, it adopts the world-wide batch process production process. There are many production links, low utilization rate of raw materials, high labor intensity of workers, and serious pollution of exhaust emissions. After many trials, the company successfully developed a continuous process production process. Last year, the company invested 26.45 million yuan to transform. After the unit is put into production, it can save 100 tons of raw material isophthalic acid, 1000 tons of thionyl chloride, and save more than 20,000 tons of water. It can produce 3,000 tons of commercial sodium sulfite and calcium chloride from recycled sulfur dioxide and hydrogen chloride, increasing direct economic benefits annually. More than 5 million yuan. Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. It is welded both inside and out to provide suffcient strength and prevent leakage. Slip-On Pipe Flanges. As made obvious by their name, these pipe flanges slip over the pipe. They're manufactured with an inside diameter that is slightly bigger than the pipe's outside diameter. These attachments are connected to the pipe via fillet weld at the top and bottom of the flange.
