Components of a Wellhead

If you work in the oil industry, you probably came into contact with the wellhead at some point. However, many people do not know the main components of the wellhead. Read on to learn about the main components of the wellhead.

Casing Components
There are three main parts of the casing: the head, the spool and the hanger.

The casting head is used to help isolate the surface casing from all external factors. The head also helps to support the weight of workers while drilling.

A casing spool usually consists of several strings, but certain ones have only one string sometimes. During drilling, the casing spool works as an additional sealing device.

There are two types of casing hanger: slip and mandrel. When the pipe gets stuck, the worker will install the sliding hanger, then you can replace the sliding hanger after cutting the casing. If threading on the wellhead is convenient to use, mandrel hanger is the preferable choice.

Tubing Components
The tubing also has two main parts: the head and the hanger.

The tubing head allows the tubing to be suspended. In addition, the tubing head helps maintain high-pressure operations and test for different seals of the well.

As for the hanger, ‘dog nut’ some people also call, seals the wellhead and keeps it locked. There are several types of hangers and adapters that can be used for different purposes, so be sure which one works for your condition.

Pack-off Components
Although they are not so pervasive, the pack-off flange is still worthy to be noted. They are usually installed above the casing head or spool and provide additional seal.

Whether you are a beginner or have been engaged in the oil industry for decades, you should have a clear understanding of the main components of the wellhead.

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. ...

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.

Quenching And Tempering For Cast Grinding Balls

  What is grinding ball heat treatment After grinding balls are manufactured in casting ball metal mold or automatic grinding ball molding line , the next most important process is heat treatment. Grinding ball heat treatment includes quenching and tempering. Grinding ball heat treatment is used to quenching and tempering for casting balls. Why grinding ball need to heat treatment furnace For casting steel ball, the most important is the balls quality. According to the casting production technology, most users are using two ways to control grinding balls quality. First, they must control well the chemical composition, this step is very easy to come true. Second, the most important is by heat treatment furnace. The main purpose of grinding ball heat treatment furnace is to improve grinding balls quality, change its internal performance and improve its harness. Quenching process is cooling grinding balls at a rapid rate from a predetermined high temperature. This...
