Kelly Valves-Drill Pipe Safety Valve
Kelly Valve/Drill Pipe Safety Valve is a full opening valve that provides positive pressure control of the fluids in the drill string.
Product Description
Kelly Valve/Drill Pipe Safety Valve is a full opening valve that provides positive pressure control of the fluids in the drill string. These valves can be used as a drill pipe safety valve or upper kelly valve to control blowout pressures, or as a lower kelly valve to prevent loss of drilling fluid when the kelly is disconnected.
Product Features
The valve seals in both directions with metal to metal seals. Available in 10,000 psi working pressure as standard, 15,000 psi working pressure is available in certain sizes upon request. The valve uses a hexagon socket on the operating stem and has positive stops in the open and closed positions.
With the exception of the standard body, all components are manufactured from materials meeting the requirements of the National Association of Corrosion Engineers (NACE) Standard MR0175 "Standard Material Requirements, Sulfide Stress Cracking Resistant Metallic Materials for Oilfield Equipment"How to Order

A Complete Guide To Gate Valve
The gate valve is the most common shut-off valve. Unlike ball valves, they are not quarter-turn devices; instead, they close and open through revolutions of the hand wheel.
Used in wastewater plants, power plants and process systems, the threaded system of the gate valves give them an advantage over the quarter turn system of the ball and butterfly valve in large applications.
Fluid through gate valves experiences only minimal pressure drop as gate valves allow total flow through its passage when fully open.
This post discusses the functions, symbols, advantages and disadvantages, types, and other essential things you need to know about the gate valve.
What is A Gate Valve?
Gate valves can also be called sluice valves or knife valves. They are control valves that allow or restrict the flow of media completely. Gate valves use a flat gate to close off flow between pipe flanges.
A gate valve, being a full port valve, has an equal diameter to the pipe through which the fluid passes. Hence, unlike butterfly valves, gate valves minimise pressure losses in the fluid when fully open. Also, because of the equal pipe and valve diameters, gate valves allow for the movement of pigs within the pipe for cleaning and inspection operations.
While butterfly valves can be used in flow regulation and on-off services, gate valves should only be used in on-off services as blocking valves and also to allow fluid flow. They should not be used in throttling.
Because of their uncomplicated construction and capability to be used in different low-pressure applications, gate valves are one of the most common valves in the industry.
Gate Valve Symbol
The gate valve symbol is composed of two triangles meeting at a point. A vertical line is inserted between the triangles, and solid horizontal lines extend from the opposite sides of the triangle.
The vertical line indicates the blocking operation of the gate valve, and the horizontal lines show that the valve has a two-way function in on-off applications.
The gate valve symbol used in piping and instrumentation diagrams (P&ID) is a modification of the valve symbol, which is the gate valve symbol without the vertical line between the triangles.
The three isometric symbols in the diagram indicate symbols for butt-welding end connections, flanged ends, and socket ends connections.

oilfield christmas tree and wellhead components
The oilfield christmas tree is an assembly of valves and accessories, used for fluid control of oil and gas wells, and provides access to the production tubing string. It includes all the equipment on the upper flange of the tubing head. The oilfield christmas tree assembly can be used in many different combinations to meet the needs of any special purpose. According to different functions, the oilfield christmas tree is divided into special wellhead devices for oil production (self-injection, artificial lift), gas production (natural gas and various acid gases), water injection, thermal production, fracturing, acidification, etc. And form series according to different pressure levels. oilfield christmas tree and wellhead components are mainly used for gas production and gas injection. Because the relative density of natural gas is low, the pressure of gas injection is low, regardless of whether the gas production or gas injection wellhead pressure is high, the flow rate is high, and it is easy to leak. Sometimes there are corrosive media such as H2S and CO2 in the natural gas, which is harmful to the tree. Tightness and its material must have stricter requirements. Sometimes for safety, double valves are used for oil and casing. For some high-pressure and ultra-high-pressure gas wells, the valves are integrally forged with high-quality steel. The main pressure-bearing parts of the companys Christmas tree and tubing head cross are made of forgings or specially smelted castings, so they have the characteristics of high pressure bearing, safety and reliability.
Function
1. It is the base of the oilfield christmas tree. Hanging and fixing the oil pipe hanger. 3. Pack the casing annular space. 4. It is the casing operation window. 5. Provide a control channel for the downhole safety valve and a penetration channel for the electric pump cable.
10 wellhead components
casing head
The casing head is a kind of part connecting casings and wellheads. It provides a transition joint for the tubing head.Christmas tree and other wellheads. Both top and bottom connections are API 6A flanged, and the flanges are provided with locking bolts. Casing Heads have a straight bore bowl with 45 C landing shoulder design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied. Casing Heads are normally furnished with threaded outlets and studded outlets are available upon request. Bottom connections can be furnished threaded or slip-on for welding.
The tubing head is the uppermost tee in the wellhead assembly. It provides a means of supporting and sealing the tubing column. The upper portion has a straight bowl and a 45â?? loaded shoulder to support and seal the tubing column by tubing hanging. It is designed to accept packing mechanisms that seal casing strings and hanger and packing mechanisms that can be used to suspend and seal tubing strings.
