If you work in the oil industry, you've likely come in contact with a wellhead at one point or another. However, many people don't know the components that make a wellhead operate. Keep reading to learn the primary components of a wellhead.
There are three main casing components: the head, spool, and hangers. The casing head is there to help isolate the surface casing from any external factors. The head also helps support the weight that workers impose while drilling. The casing spool usually includes several casing strings, but some will only have one string. The casing spool acts as an additional seal to the head during the pressure from drilling. Lastly, the casing hanger can come in two types: a slip or mandrel hanger. Manufacturers install slip hangers when a pipe is stuck because you can replace a slip type after cutting the casing. You would use a mandrel hanger if you're readily able to use the threading on the wellhead. In general, casing hangers are a primary seal against interior elements.
The tubing also comes in two primary components: a head and hanger. The tubing head allows for the suspension of tubing. Additionally, the head helps the well maintain high-pressure operations and testing different seals. The hanger, many refer to it as a dog nut, seals the wellhead and remains locked. There are several types of hangers and adapters for various uses, so be sure to contact an expert before your next purchase, or do some research to know which hanger is best for you.
Pack-off Components
Though they aren't as popular anymore, pack-off flanges are worth noting. They're usually found above the casing head or spool and offer an additional seal. Pack-off flanges are only helpful when you have to re-enter a well. However, these flanges can be helpful in testing and plugging a drillstring.
You should have a general understanding of the primary components of a wellhead whether you're just beginning or you've been in the petroleum industry for decades. A wellhead is something you'll be in contact with several times throughout your career.
