How to solve the corrosion protection of bolts and nuts?
The corrosion of fasteners (nuts and bolts) is an ancient problem that has existed since the first use of nuts and bolts. Threaded fasteners are a weak link in corrosion protection. Many industry (pipe, chemical facility) production management leaders believe that fastener corrosion is not their main concern, and they have not considered the impact on cost. Corrosion will make the metal surface uneven. For fasteners, the corrosion will soon start the rusting of the thread and the metal conversion, which shows the strength of the thread connection is reduced, and the bolt and nut cannot be removed, which causes great trouble for maintenance. The inability to remove bolts caused by corrosion will prolong the maintenance time and increase the cost. Especially large bolts need to be removed with a nut splitter or a torch. For petrochemical production, the safety risk is undoubtedly greatly increased.
In today’s chemical companies, most of them use simple anti-corrosion to resist these corrosion,but they do not play a fundamental role, such as: galvanizing, hot-dip galvanizing, blackening, oiling, etc., the effect is not significant, the replacement is still in progress Frequently in progress.
At this time, the emergence of FLUOROCARBON coatings solved a series of problems. It has excellent corrosion resistance,high temperature resistance,excellent wear resistance and stickiness resistance,prevents dust adsorption and excellent wear resistance and weather resistance.
Recently Hebei Haihao Group finished a batch of stud bolts c/w 2 nuts A193 B7/A194 2H coated with Fluorocarbon heavy hex nut with Tommy Bar Hole . If you have any question,please don’t hesitate to contact us! Email:sales@haihaogroup.com
