The Difference Between Wellhead and Christmas Tree

Oilfield Xmas tree and Wellhead are two distinct devices but with several things in common. For instance, they are both of great importance of oil and natural gas production; Valves and other equipment appear in both devices to help control and guide the flow of materials. Out of their similarities, they are often used as the same thing. But, they are two distinct pieces of equipment as mentioned before. To better figure out the differences between these two, keep reading, please.

Xmas Tree
The Christmas tree, which usually constitutes of valves, spools, choke coils and accessories, is named out of it looks like the decorated tree for Christmas celebration. There are five valves in a Christmas tree: the Kill Wing valve, the Swab valve, the production wing valve, the upper master valve, and the lower master valve. Christmas could be found in a wide range of wells including oil wells, gas wells, water disposal wells, water injection wells, gas injection wells, and several other types of wells. In the process of production of materials -- usually oil or natural gas, the Christmas tree there is used to regulate the rate of the flow into and out of the well.

Other functions of Xmas tree cover well intervention, pressure relief, chemical injection, tree and well monitoring points, flow composition and rate, valve and choke position feedback, connection points.

Wellhead
Wellhead assembly components include heads, hangers, spools, and a series of seals. During drilling and production, the wellhead is necessary to control the pressure. Without wellhead, you cannot utilize a Christmas tree. However, you can use a wellhead without a Christmas tree during drilling operations. Additional functions of a wellhead include: allows safe and controlled access to a live well; serves as a point to suspend casing and tubing strings; serves as a connection surface pressure-control equipment.

Chiller installation technology

1. When selecting the position of the lifting point, first consider the best position of the air circulation, and secondly consider the direction of the structure of the storage body. 2. The gap between the chiller and the slab should be greater than the thickness of the chiller . 3. All the slings of the chiller should be tightened, and the bolts and slings should be perforated with sealant to prevent cold bridge and air leakage. 4. When the ceiling fan is too heavy, use the No. 4 or No. 5 angle iron as the lintel. The lintel should span across the other roof and wall panels to reduce the load.

Copper rod machine melting,Copper rod upcasting machine,Copper plating line

China is short of copper, and China is also a big copper user. At present, the copper consumption of China's cable industry is about 7.5 million tons, accounting for more than 60% of China's total copper consumption, accounting for about 1 percent of the world's total copper conductor consumption, making it the largest copper user in the world. In order to solve the serious situation, the smart Chinese people try to use the machine which could meet the energy-saving requirement to produce the cooper rod. D&S copper rod making machine adopts the advanced fire refining technology to produce the￠8MM bright low-oxygen copper rod which is meet the international standards in the continuous casting line. The features of the production line are continuous casting and rolling process. There is no interruption from melting of raw material, casting process, rolling process and delivery of product, and it has high efficiency due to automatic control throughout the entire process. ...
