What is Weight Per Foot?
The weight per foot of OCTG refers to the weight of the casing or tubing per linear foot. The weight per foot is an important parameter used to in the design, installation, and transportation of OCTG products. The weight is typically measured in pounds per foot (lb/ft) or kilograms per meter (kg/m).
The weight per foot of OCTG depends on several factors, including the outer diameter, wall thickness, and the specific grade and type of casing or tubing. The dimensions and specifications of OCTG are typically standardized by organizations such as the American Petroleum Institute (API).
To determine the weight per foot of OCTG, you can use the following formula:
Weight per foot (lb/ft) = [(OD – Wall thickness) x Wal Thickness] x 10.69
In this formula, the outer diameter (OD) and wall thickness are usually expressed in inches. The resulting weight per foot will be in pounds.
It’s important to note that the weight per foot can vary for different sizes and grades of OCTG. The specific weight per foot values can be obtained from product specifications, manufacturers’ catalogs, or industry references for the specific OCTG casing or tubing you are interested in.
