Steel casing thread type refers to a threaded connection method commonly used in the petroleum industry. Threaded connection is a way to connect two pipe fittings by interlocking threads. It has the advantages of firm connection and reliable sealing, and has been widely used in the petroleum industry.
What are the different types of threads in casing?
There are two main types of steel casing threads: internal threads and external threads. Internal threads refer to the threaded structure inside the pipe fitting, while external threads refer to the threaded structure outside the pipe fitting. According to different connection requirements and usage scenarios, the types of steel casing threads are also different.
In terms of internal threads, common steel casing thread types include NPT, RP and LP. NPT is the abbreviation of National Pipe Tapered Thread, which is a commonly used internal thread type in the United States. NPT thread has a taper angle of 1:16 and is suitable for connecting low-pressure liquids and gases. RP is the abbreviation of Round PipeThread, which is a commonly used internal thread type in the UK. RP thread has a taper angle of 1:16 and is suitable for high-pressure liquid and gas connections. LP is the abbreviation of Line Pipe Thread, which is a type of internal thread commonly used in the petroleum industry. LP thread has a taper angle of 1:16 and is suitable for connections that transport media such as oil and natural gas.
In terms of external threads, common steel casing thread types include BTC, STC and LTC. BTC is the abbreviation of Buttress Thread Casing, which is a type of external thread commonly used in the petroleum industry. BTC thread has a flat taper angle and a large pitch, and is suitable for connecting oil well casing. STC is the abbreviation of Short Thread Casing, which is also a type of external thread commonly used in the petroleum industry. STC threads have smaller pitch and shorter length and are suitable for general oil well casing connections. LTC is LongThread
The abbreviation of Casing (long thread pipe thread), it is also a type of external thread commonly used in the petroleum industry. LTC threads have larger pitch and longer length and are suitable for oil well casing connections under special circumstances.
In addition to the common steel casing thread types mentioned above, there are also some special thread types, such as VAM, T&C, etc. VAM is a high-performance steel casing thread developed by the French company Vallourec. It has excellent sealing performance and load-bearing capacity and is widely used in the petroleum industry. T&C is the abbreviation of Thread and Coupling. It is a common way of connecting steel casings. The connection is achieved by meshing the threads of two pipe fittings with each other.
