Expanding Gate Valves

X-mas Tree Caps A valve is equipment that is utilized in a household as well as in a large industry; the types of valves obviously differ as per requirement. The basic function of a valve is to either check or control the flow of a fluid. There is also pressure-check valve which has a different function altogether. One may wonder why different types of valves are designed for such an incomplex task. It is because different types of flows like partial flow, full flow or no flow are required by industries. Valve types like the gate valve are suitable only where full or no flow is needed, for throttle purposes a gate valve is of no use. Gate...

Wellhead equipment – Backbone of Oil Extraction Industry

Wellhead Equipment 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: a)  Tubing Heads and...

Common Types of Valves

FC gate valve  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 used valves in today’s industry. Categories of Valves They basic type of valves fall into two categories; *      Check valves and *      Close valves. As the name suggests, they have only...

Pulsation Dampeners For Oil and Gas Industry

Pulsation dampeners can be used for the following cases:It can be used for leakages in a hydraulic system. Also it can be used for any pressure changes due to thermal expansion. It can be used as an energy storage device (Accumulator) in a hydraulic system. It supplies hydraulic power for a short period of time. This property is crucial for lube oil system which has to supply lube oil to critical rotating equipment wherein slightest delay may result in a costly failure to the equipment. Pulsation Dampeners installed close to the valves is used to absorb the surge which is risen from the sudden pump shut-downs when the fluid flows back slamming into the pump or check valve. It can be used in absorbing the surges like water hammer results from the sudden change of kinetic energy...

Wellhead Equipment

Wellhead equipment are used in connecting the casing and  tubing  to an oil or gas pipeline. These are useful in suspending the casing strings and help seal the well. The casing is a permanently-installed pipe for lining the well hole to provide pressure containment and prevent collapse. The wellhead equipments are known as the flanged devices that are attached to the casing.Wellhead equipments include a number of other components such as casing heads, casing spools, tubing head spools, tees, and crosses. The casing head is part of the connection between the casing and the wellhead equipment itself. Usually, many...
