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.

Dingya Crane Provides High-configuration Metallurgical Cranes

  Metallurgical cranes refer to   bridge-type cranes   used in metallurgy, casting and other places for lifting molten metal. They are also called metallurgical cranes. Nowadays, many small cast iron, cast steel and other metal smelting companies are using ordinary   single-girder cranes , but due to their design limitations, there are obvious hidden dangers, and the service life is greatly reduced. It is safer to switch to metallurgical driving as required. Compared with cranes used by general enterprises,   Dingya metallurgical cranes   have the characteristics of frequent use, harsh environment, high security performance and high automation. Starting from the transmission scheme, to the selection of components and wires, as well as component layout, wiring methods, and even electrical the sealing, cooling and other issues of the room and cabinet have been comprehensively considered and designed. Since there are many types of metallurgical cranes and each...

Classification of diamond drill bits

  1. surface set diamond bit Explanation: A kind of diamond drill bit . The steel cylindrical bit body has a wire buckle on the upper part and a sintered drill head body on the lower part. The diamond particles are encrusted on the surface of the drill head body. The outer diameter of the carcass is slightly larger than the diameter of the steel body and the inner diameter is slightly smaller than the diameter of the steel body. There are grooves inside, outside and at the bottom that allow water to pass through the carcass. During drilling, washing fluid is used to carry away rock powder and cool the bit. Diamond-impregnated bits are all encrusted with natural diamonds and are therefore expensive, so they are only used in hard formations that are particularly difficult to drill. Diamond-impregnated drill bit is more commonly used in oil drilling. 2. impregnated diamond bit Explanation: A kind of diamond drill bit. A drill bit whose head body is uniformly encrusted...
