What is API drill pipe?
API Grade Drill Pipe Grade E drill pipe, referred to as “mild” steel, exhibits the lowest yield strength per unit area with a yield strength of less than 80,000 psi. It is able to withstand a greater percentage of stretch or “strain” prior to fracture than higher strength drill pipe grades.
What is the weight of a drill pipe?
The length of a drill pipe is typically Range 2 at 31 feet but can come in other lengths as well. A drill pipe is thick-walled and designed to hold its own weight in a drill string as the drill pipes are often run thousands of feet under the surface.
How heavy is drill stem pipe?

Why we use heavy weight drill pipe?
Heavy weight drill pipe also enables drilling at higher RPMs, reducing torque and differential pressure sticking. Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling.
What is Range 2 drill pipe?
Drill pipe tubes are furnished in the following API length ranges: • Range 1: 18-22 ft; • Range 2: 27-30 ft; • Range 3: 38-45 ft.
What is API RP 7G?

What is range 3 drill pipe?
What is the function of drilling stabilizer?
A drilling stabilizer is a piece of downhole equipment used in the bottom hole assembly (BHA) of a drill string. It mechanically stabilizes the BHA in the borehole in order to avoid unintentional sidetracking, vibrations, and ensure the quality of the hole being drilled.
What does API mean in pipe?
An API (American Petroleum Institute) 5L line pipes are manufactured in two forms, PSL 1 and PSL 2. PSL stands for Product Specification Levels. PSL stands for Product Specification Levels. These specs cover seamless and welded steel line pipe from grades X42 through X80.
What are pipe specifications?
The Piping Specification (abbreviated: Pipe Spec) is a document prepared during the design phase of any project. It provides the appropriate selection, specification and material grade of pipe and piping components for a given service.
What are the specifications of ductile iron pipe?
