Calculate the drill pipe’s buoyancy factor by subtracting the mud weight from 65.5 and dividing the answer by 65.5. In the example, 65.5 minus 20 equals 45.5.

How long is a length of drill pipe?
27 to 32 feet
It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3).
How is drill pipe length calculated?
Calculate the drill pipe’s buoyancy factor by subtracting the mud weight from 65.5 and dividing the answer by 65.5. In the example, 65.5 minus 20 equals 45.5.
How long is a joint of drill stem pipe?
A length of pipe, usually referring to drillpipe, casing or tubing. While there are different standard lengths, the most common drillpipe joint length is around 30 ft [9 m]. For casing, the most common length of a joint is 40 ft [12 m].
What size pipe is drill stem?
2 3/8”, 2 7/8” and 3 1/2” Drill Pipe for Common Use. In API 5DP specifciations, the common use OD are 2 3/8”, 2 7/8” and 3 1/2” drill pipes, these usually required in large amount of quantities in drilling activities.
How long is range 3 pipe?
38-45 ft.
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 the difference between drill string and drill pipe?
The drill pipe constitutes the majority of the drill string length. It is seamless with threaded connections. The drill pipe has two tool joints, one female is called a box and the other male is called pin. The outer diameter of the tool joint is larger than the body of the drill pipe to accommodate the threads.
How long is Range 2 drill pipe?
27-30 ft
How is drill pipe tensile strength calculated?
Tensile strength = Minimum Yield Strength × Cross Sectional Area. Minimum yield strength of pipe can be found in the grade of the string. For example, the pipe grade if J-55 has minimum yield strength of 55,000 psi. The number after alphabet represents the minimum yield strength in 1,000 psi.
What is range 3 drill pipe?
Range 3 (R3) is common in casing and also deployed in deep water drilling applications. The increased length decreases the number of tool joints in each stand of drill pipe. The fall back being that the load exerted on each tool joint is greater increasing wear and reducing the expected life of the drill pipe.
How long is 1 stand drill pipe?
The drill pipe “joints” are made in 31.6 ft (9.6 m) lengths and are run and stored horizontally on the ship in three-joint sections known as “triples” or “stands” (Fig. 3).
What are the different grades of drill pipe?
API (American Petroleum Institute) divides drill pipe steel grades into five grades: D, E, 95(X), 105(G), 135(S). The higher the drill pipe steel grade, the greater the yield strength of the pipe, and the greater the various strengths of the drill pipe.
What is the difference between drill pipe and drill collar?
Learn about this topic in these articles: pipe are extra-heavy sections called drill collars, which serve to concentrate the weight on the rotating bit. In order to help maintain a vertical well bore, the drill pipe above the collars is usually kept in tension.
What sizes do drill pipe tongs come in?
These tongs are available in sizes 2 3/8 – 10 inches. Available with an array of models to choose from Standard, Hydra-Shift, High Torque, and Ultra High Torque, depending on your torque requirements. Drill Pipe Tong Models 4-1/2 UHT-20
What is the length of a 6 5 8 pipe?
This same 6-5/8-in. pipe is typically manufactured with 10-in. Pin Tong Length and 13-in. Box Tong Length. Some of the tong space may be lost to Hard Banding — since you cannot grip hard banding with the rig vises or jaw dies on tongs. It is important to look at the Useable Tong Length of Pin and Box tool joints when considering buying used pipe.
What sizes do torque tongs come in?
These tongs are available in sizes 2 3/8 – 10 inches. Available with an array of models to choose from Standard, Hydra-Shift, High Torque, and Ultra High Torque, depending on your torque requirements.
What is an Eckel drill pipe Tong?
Drill pipe, an industrial tubular used for drilling into the ground, are screwed together using a tong to form a drill string. Eckel Drill Pipe Tongs reduce drill time and costs while providing a safe means environment.
