Introduction Of API 5L, API 5B, API 5CT And API 5D
API standards are designed to qualify the oil and petrol industry according to the legislation and environment requirements. According to API, oil and natural gas industry can have the reference standards about its industry.Under the general standards, there are some subordinated specifications drafted for each specific OCTG product, such as API 5B, API 5CT, API 5D, API 5L and so on.
API 5B covers dimensions, tolerances and marking for API threads, and gauge used for control acceptable criteria for threads. That standard includes thread element gauges, instruments, and requirements for the inspection of threads for line pipe, casing and tubing (round threads), and buttress casing connections. API tubing, casing, and line pipe threads are governed by the Specification 5B. The Sixteenth Edition has made some major changes, including mandating the inspection of thread addendum. 5B 1.2 lists out the new inspection requirements including addendum. 5B 4.8 states that all threads shall be controlled in accordance with gauging practice.
API 5L Covers Seamless and Welded Steel Line Pipe.It provide specification for pipe used in conveying gas, water, and oil in both the oil and natural gas industries. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe; as as well as bell and spigot and through-the-flow line(TFL) pipe.
Grades covered by API 5L are A25 ,A ,B (and the following 'X' Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the 'X' indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.
API 5B and 5CT are mainly used for casing and tubing.
API 5B, Specification for Threading, Gauging and Thread Inspection of Casing, Tubing, and Line Pipe Threads.This Specification covers dimensions, tolerances and marking requirements for API threads and the gauges that control the acceptance criteria for the threads. Thread element gauges, instruments and requirements for the inspection of threads for line pipe, round thread casing, and buttress casing connections are included.
API Spec 5CT, Specification for Casing and Tubing, Eighth Edition, Petroleum and natural gas industries-Steel pipes for use as casing or tubing for wells.This Standard specifies the technical delivery conditions for steel pipes (casing, tubing and pup joints), coupling stock, coupling material and accessory material and establishes requirements for three Product Specification Levels (PSL-1, PSL-2, PSL-3).
API 5B and 5CT steel grades are namely H-40, J-55, K-55, N-80, L-80, C-90, T-95, P-110, Q-125.Steel grade H, J, K, N in the first group are of relatively low strength. Grade L, C, T represent restricted-yield casing and tubing which are normally anti-sulfur and anti-corrosive. P-110 in the third group is a high strength steel grade.Grade Q-125 is for high strength.
API 5D is under the jurisdiction of the API Committee on Standardization of Tubular Goods.The purpose of this specification is to provide standards for drill pipe suitable for use in drilling and producing operations.API 5D covers Group 1 and Group 3 drill pipe in the designations. API 5D Group 1 - Grade E drill pipe.Group 3 - All high strength grades of drill pipe. (Grades X-95, G-105, and S-135)
API has given each products its special specifications for reference.the main products of OCTG are tubing, casing, drill pipe, drill collar, sucker rod and pipe line. Generally, the standard for tubing and casing is API 5CT standard and API 5D is the standard of drill pipe, while, about line pipe specification,that's API 5L. If you want to process, measure and inspect the screw thread of casing, tubing and pipeline, API 5B is the your choice.
Other Relevant topics:
The API 5B specification covers marking requirements and dimensions utilized by API Master thread gauges. The 5B specification is used when measuring pipe, tubing and casing threads, and each adheres to a specific set of guidelines. Various additional thread gauges and featured product threads are required when the API 5B specification is used. The following adhere to API 5B specifications:

- Line pipe thread inspection
- Buttress casing
- Round thread casing
- Extreme-line casing
API 5B Applications
API 5B specifications are applicable when API standards govern a product. Similarly, API 5B inspection procedures are used on threads featuring 11.5, or less, turns per inch. API 5B inspection procedures utilize the following measurements:
- Taper
- Lead
- Height
- Angle
Each thread dimension is measured and shown without included tolerances are considered connection design bases, and they’re not related, nor subjected to, measurements utilized to determine a product’s acceptance or rejection. Each manufacturer and purchaser is required to agree upon supplemental requirements before using API 5B specifications.

API 5B Inspection
Api 5b Thread Spec
API 5B specification thread inspection is used prior to shipment events. Manufacturers frequently measure a thread’s various intermediate points, and they inspect each again during destination delivery. Additionally, inspectors representing both the manufacturer and purchaser are required to inspect each 5B specification.
Manufacturers may utilize different methods and instruments to control manufacturing operations, and they may become flexible where specification application is required. However, acceptance or rejection of a product is entirely governed by an inspection’s results. This rule is often featured in accordance with a provided 5B specification listing, and is held in high regards during every inspection. Each API 5B specification requires consultation before implementation, and requirements must be provided by the manufacturer.
