Oxygen transmission pipelines operate under high oxygen concentration. If grease or oil residues exist inside the pipelines, even a tiny spark will trigger an explosion. For this reason, all valves fitted on such pipelines must be completely degreased and kept free of any grease or oil.
View MoreThe UREA 316L Modified grade has been speciallydeveloped for Urea plant applications. It is a 316Lmodified stainless steel with extra-low silicon contentand substantial higher molybdenum contents.The low carbon content, combined with a well balancedchemistry (low silicon and nickel content close to 14%)makes the alloy fully austenitic, free of intermetallicphase precipitations. The ferrite level is kept under 0.5%in the solution annealing and water quenched conditions.The alloy is designed for improved corrosion resistanceproperties in Urea-carbonate environments.
View MoreThe maintenance of butterfly valves is essential to ensure their long-term stable operation and extend their service life. The following are maintenance recommendations for butterfly valves:
View MoreGate valve is a common type of valve, mainly used to cut off or connect the flow of fluid. Due to its simple structure, good sealing performance and wide range of applications, it is widely used in various industrial and civil pipeline systems. The following are the main uses of gate valves:
View MoreCheck valve, also known as non-return valve or one-way valve, is a valve that can automatically prevent fluid backflow. It mainly relies on the flow of the medium itself to open and close the valve disc to prevent the medium from backflowing, and plays a role in protecting equipment and pipeline systems. The following is a detailed introduction and description of the check valve
