Spheroidal graphite The scope of application of is as follows:
one It is suitable for controlling power plants, hydraulic slag removal or gas transmission pipelines. The ball adopts a combined bimetallic ball with high rigidity.
2. It is suitable for crude oil, heavy oil and other petroleum products in the chemical industry, and can withstand the temperature up to 425 ℃.
three It is suitable for sewage treatment, paper pulp, gasified aluminum and occasions with strict requirements for urban heating.
four It is applicable to the transportation control of coal gas and liquefied gas. The product structure is characterized by the different chromium containing alloys of the seal ring surfacing valve, and the sealing performance is good.
five It is suitable for liquid and solid two-phase mixed flow or industrial pipeline transportation, where the chemical reaction in liquid transportation will lead to crystallization or scaling. The structural characteristics are based on different media and temperature requirements required by customers. The ball surface is covered with chromium molybdenum and vanadium alloy, and the valve seat surface is covered with chromium, molybdenum alloy, chromium alloy and stainless steel alloy electrodes to meet the needs of different slurry transportation.
