Those familiar with the terminology of drilling rig must know what a pulsation dampener is, but for others it might sound confusing. A pulsation dampener is actually a vessel, which is filled with gas, mostly Nitrogen. The main function of a pulsation dampener is to isolate the gas from the circuit liquid so as to avoid the loss of gas. The material used to separate the fluids is generally made of Nitrile and (NBR) and Hydrogenated Nitrile (HNBR). There are several other functions of a pulsation dampener besides from separating gas from fluid. Like for example, the extreme pressure that is discharged on the side of the positive displacement...

Elastomer Products – Pipe Wipers

There is a huge range of elastomer products that are put to use in different industries. Like for example, in the automobile industry, elastomer products like ball joints and anti-vibration mounts are used. Annular blowout preventer packing unit, annular blowout seal kits, ram blowout spare parts, pipe wipers, wiper cutter assembly, drill pipe protector, tong and elevator straps and aero union tubes are some of the Elastomer products used in the oil drilling industry. To begin with, pipe wiper is not a pipe or has nothing to do with a pipe. It is in fact a device shaped like disk, which is generally made of rubber and has a hole in the center....

Wellhead equipment – Backbone of Oil Extraction Industry

Expanding gate valves Wellhead is the equipment that is mainly used to connect casing to an oil pipeline. Casing strings are a type of oil field pipe. Wellhead equipment provides pressure seals to these pipes. There are several other functions of wellhead equipment such as providing tubing suspension, giving space for tubing, acting as an attachment for blowout preventers and so on. These equipment are generally installed during the first phase. However, it functions even after the wellbore is shut down. As aforementioned, wellhead equipment consists of various components. Some of the Components of Wellhead Equipment: Tubing Heads and ...

Save big bucks by investing in Drill pipe protectors

         Drill Pipe Protector       A drill pipe is a 30-33 feet long and sturdy steel pipe. The length, height and weight of a drill might differ, however in most cases the height does not exceed 33 feet. As stated above, a drill pipe is used for extracting oil from wellbores. The structure of drill pipe is hollow from within, which makes it easier to extract oil from the wellbore without getting stuck to the pipe. Threaded ends are joined to a drill pipe, which are then known as tool joints. These help connect the top drilling equipment to the bottom drilling equipment of the rig. A drilling pipe is...

Common Types of Valves

No extraction equipment can be constructed without a valve. However, every industry has its own set of requirements. This is the reason why various types of valves are designed. Let us take a look at the various types of valves and what exactly their functions are. The device that has control over the flow and regulation of any fluid is known as valve. The function of re-direction or/and controlling fluid is done by closing, opening or partially opening/closing the passageway. Most of the valves function this way, however there are few others that function differently, like the thermostatic re-circulating valve. Following are some of the commonly...

Annular-type Blowout Preventer

annular blowout preventer A drilling rig works efficiently due to all its components. Wellhead equipment, blowout preventers, mud pump, pipe ramp etc are some of the important components of any drilling rig. Of the above mentioned components, blowout preventer is one of the fundamental components. BOP is a special type of valve which deals with extreme pressures that can lead to explorations. The sub-types of blowout preventers are used to seal the wellhead to stop the flow of fluid (oil) from the wellbore. Ram BOP and annular BOP are the two types of BOPs. The major difference between the two is between the techniques used to function. One...
