Casing Pipe FAQ Guide

How to Install Well Casing?

How to Install Well Casing

  • Insertion of the casing pipe in the well
  • Know how deep your well is
  • To put the casing pipe in the wheel
  • Fill in gravel
  • Put casing pipe in the ground
  • Finish the well cap
How to Remove Well Casing?

Things need to prepare: drill rig with augers, certified well driller, driller’s helper, chain or strap. Then, let’s start!

  1. First, loosen the surrounding materials, please choose a hollow-stem auger with an inside diameter larger than the diameter of well casing. For example, if the well casing is 4 inches in diameter, overdrill the well by 8 inches or larger auger.
  2. Put chain or strap to the well casing. When the overdrill is done, leave the augers in the ground and attach the chain or strap to the casing and the auger.
  3. Using drill rig to pull the old casing from the ground. Be careful that old casing such as PVC materials is easily broken, which creates needless pollution underground.
What Size is Well Casing?

What Size is Well Casing

In general, residential wells use 4, 5, 6 inch casings. And agricultural wells or older wells use larger casings, such as 8, 10, 12 inch or even bigger diameters depending on the practical applications.

What are the Differences between Casing Pipe and Drill Pipe?

What are the Differences between Casing Pipe and Drill Pipe

  • Purpose

Drill pipes conducts force to the drill bit when drilling process. Drill pipe is the first step of every wellbore. However, casing pipe is applied to protect and support the well stream, it can also stabilizes the wellbore, which requires each casing pipe to withstand high collapse pressure.

  • Standards

Drill pipe needs to in line with API standard, its purpose is to set requirements of drill pipe to meet the producing operations conditions. Meanwhile, casing pipe from materials to strength have different standards, such as APT, ISO, DIN, etc.

  • Connection

Drill pipe has wider range of connection types than casing pipe, casing pipe is limited by threads.
