"Speaking of valves, the first thing people think of is often the cumbersome "iron bump" image.
China's leading customized valve manufacturer, ZJLQ Special Valve Company, uses high-performance titanium alloy forging rods to process special high-performance valves worth more than one million RMB.
Titanium alloy rod is a special metal material with high strength, corrosion resistance and other characteristics, and the price is as high as 200 yuan per kilogram.
ZJLQ has just received an order for special valves from Sinopec/China Petroleum & Chemical Corporation. It will use high-performance titanium alloy materials to make stop valves and check valves, which are specially designed for high-strength, corrosion-prone special working conditions.
Prior to this, ZJLQ had customized ball valves made of titanium alloy material TA2 with a diameter of DN300 for other companies. The unit price was as high as more than 1 million yuan. The price of the materials used in this valve was extremely high, and the pressure level was much higher than that of ordinary valves. Great recognition. In addition, the special material valves they have sold include nickel, zirconium, Hastelloy, Inconel, Monel, low temperature steel, copper, 20# alloy steel, dual-phase steel and other valves. Due to the particularity of materials and processing techniques, the prices of these valves range from tens of thousands to millions of yuan.
