What is LTC thread?

What is LTC thread?

LTC (Long thread) The LTC thread is the same as the STC thread in the shape and can be connected, but it is generally not allowed to connect because the maximum torque they withstand is different. Casing pipe with long threads is the commonly used in the oil and gas industry.

What are API threads?

API stand for American Petroleum Institute. API pipe threads are made to the same specs as NPT. They should match with any standard pipe thread. Now, any other kind of thread, buttress, etc., does not match the american standards.

What is EUE connection?

The API external-upset-end (EUE) tubing connection is widely used because it is a good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strength greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.

What is 8rd thread?

For a thread pitch p, the crest and root rounding radius is slightly less than p/4, and approximately the middle third of each thread flank is flat. The American Petroleum Institute (API) specification 5B lists a “round thread” for tubing, often referred to as “8 round” or “8rd” for 8 threads per inch.

What is an API coupling?

API Couplings are widely used in the petroleum and petrochemical industry to effectively connect to and disengage cleaning from bottom loading tankers. The API couplers are mounted on the bottom loading arm with a flange connection which is then attached to the API valves on the petroleum tanker.

What is BTC pipe?

The Baku–Tbilisi–Ceyhan (BTC) pipeline is a 1,768 kilometres (1,099 mi) long crude oil pipeline from the Azeri–Chirag–Gunashli oil field in the Caspian Sea to the Mediterranean Sea.

What are API couplings?

How many types of threads are there?

There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).

What is API 5CT specification?

API 5CT is standard technical specifications for steel casing and tubing pipes used for oil wells in petroleum and natural gas industries.

What is EU thread?

EU(External upset) EU is a kind of external upset oil pipe joint, there are three biano logos related to EU. EUE (External Upset End) represents outside the thick end, EUB (External Upset Pin) denotes an outer thickened pin thread, EUB (External Upset Box) indicates external upset box thread.

What are 8 round threads?

The most common type of casing connection in use is the API 8-rd connection, where 8-rd means 8-round or eight threads per inch and a slightly rounded profile. The profile is a V or wedge-shape but slightly rounded at the crest and valleys of the threads.

What is API 5CT?

Who owns the BTC pipeline?

The BTC Co. shareholders are: bp (30.1 per cent); AzBTC (25.00 per cent); MOL (8.90 per cent); Equinor (8.71 per cent); TPAO (6.53 per cent); Eni (5.00 per cent); Total (5.00 per cent), ITOCHU (3.40 per cent); INPEX (2.50 per cent), ExxonMobil (2.50 per cent) and ONGC (BTC) Limited (2.36 per cent)

What is upset connection?

A pipe connection with thicker wall area at the coupling.

What are the 3 basic types of threads?

What is standard thread size?

US Standard Threads are measured in TPI (Threads per Inch). They are measured by finding the number of thread crests in 1″ of threads….US Standard Thread Pitch.

What is API 5B?

API 5B specifies the thread element gauges, instruments, and requirements for API thread inspection. It also governs the dimensions, tolerances, and marking requirements for all API threads, including threads on Line Pipe, Round Thread Casing, Round Thread Tubing, and Buttress Casing connections.

What is API 16A?

API Specification 16A defines the requirements for design, testing, and other aspects of drill-through equipment. This includes ram and annular blowout preventers as well as connectors, spools, and adapters.

Are SAE and NPT the same?

What’s the difference between SAE & NPT threads? The biggest difference is SAE is a straight thread, it needs additional O-ring, gasket or sealing surface to form a seal; NPT thread is a taper thread, it can form a seal using its thread pitch.
