Api Thread Dimensions

There is a chart available that provides the api thread dimensions for any individual who needs it. It provides information for non-upset api thread dimensions as well as external-upset api thread dimensions. It also provides coupling information. Individuals can also find information on the size, casting, length, diameter of recess, depth of recess, width of bearing face, hand-tight standoff, .

API is the American Petroleum Institute. It is the leader in developing the standards, codes, specifications, best practices and technical publications for every aspect of the petroleum and petrochemical industry. API has been working with the oil and gas industry to come to a consensus on 500 standards since 1924. Its home page can be found at: http://www.api.org/.The basic procedure for drilling for crude oil and natural gas is to first use a drill bit to cut through earth and rock. Threads are the grooves that are cut into the drill bits used in this part of the process. As the hole gets deeper, additional sections or lengths of pipe are added. This is called a drill string. The API standards for threads and couplings exists to make certain that all types of drill bits, pipes and other equipment used in this process will be compatible with one another. It is critical to drilling safety protocol that all the equipment used meets these basic standards.Thread dimensions refers to the size, casting, length, diameter of recess, depth of recess, width of bearing face, hand-tight standoff, end of threads of coupling power-tight make-up, number of threads per inch and the weight of tubular equipment used in the drilling process.There is a lot of excellent information available about thread dimensions for drilling in PDF format offered at: www.oilproduction.net. This chart lists all the pertinent information relating to nominal weight, grade and upset type, torsional yield strength, tensile yield strength, wall thickness, nominal ID, pipe body section area, pipe body section modulus, pipe body polar section modulus, internal pressure PSI and collapse pressure PSI.This chart, located at: http://www.oilproduction.net/files/casing_drilling/GrantPrideco_Drill_Pipe_Data_Tables.pdf provides all of this data for pipe dimensions from 2 3/8 inch to 2 7/8 inch. It also includes information regarding tool joint data and assembly data.
