Lubricant And Oilfield Valves: What You Need To Know

Oilfield valves play an important role on equipment used to pump oil from the ground. Some of the valves help to prevent dirt and rock from coming up with the oil, while other valves help pull oil out and through tubes and tunnels so it can be taken and refined. Regardless of what the valve is used for, it needs to be lubricated or oiled. If you are new to the oil industry, you may not know much about lubrication and oilfield valves. Here is some information you should know.

Why Your Oilfield Valve Needs to Be Lubricated

A valve generally has a knob that lifts and lowers a gate or door located inside. Failing to lubricate the valve can cause the knob or the door-like mechanism inside to fail to work. It can rust or corrode, especially when exposed to outdoor elements such as rain. Lubricating the valve helps both the external knob and the internal mechanism turn and open like they should. This helps preserve the lifespan of the oilfield valve and ensures that it operates as it should.

Signs Your Oilfield Valve Needs to Be Lubricated

There are a wide array of oilfield valves. There are knife gate valves, gate valves, reset relief valves, pressure relief valves and butterfly valves, just to name a few. Each valve has its own needs and needs to be lubricated at a different time, based on the job it does. When you purchase a valve, the manufacturer should tell you how often the valve should be lubricated. Some valves may need to be lubricated after a certain number of uses, some may need to be lubricated when they are cleaned and others may only need to be done when routine maintenance is being done. Regardless, if your valve is getting hard to turn, is showing signs of rust or corrosion, or you hear squealing or squeaking when the valve is in use, it should be lubricated.

Different Lubricants for Different Oilfield Valves

Not all oilfield valves are the same, nor do they have the same purpose. As such, there are different lubricants for different valves. The viscosity of the lubricants, or its thickness, varies. Some valves need a higher viscosity lubricant, while others need a thinner lubricant. Before lubricating a valve, make sure you use the correct type of lubricant. Using a lubricant that is not thick enough may prove to be ineffective, while using one that is too thick or creamy for the valve may weigh it down. The valve manufacturer will always tell you what type of lubricant to use with the valve.
