In threading, Rp1 Rp2 refers to how big the threaded hole is and how big the pitch is

RP1 8 pitch is pitch.

For the metric size of 28 occlusion per inch, large diameter, medium diameter and small diameter, RP1 8 is a type of parallel thread in the pipe.

RP stands for parallel or cylindrical thread in the pipe, and 1 8 means that his size is 1 8 inches. This refers to the pipe thread.

The bore size is 1 8, which is the cylindrical pipe thread, and RC is the conical inner pipe thread.

Let's start by explaining the difference between sealed and unsealed.

Pipe threads are generally divided into three types: unsealed pipe threads, generally sealed pipe threads and dry sealed pipe threads. (There are only the first two in the imperial system).

Unsealed pipe threads have only one function: mechanical linking. The processing requirements are low and the cost is low.

The general sealed pipe thread refers to the thread itself that does not have sealing (the sealing effect can be achieved by sealant, raw material tape, etc.), and is used for water, gas pipelines, lubrication and wire piping systems with pressure below the pressure. The processing requirements are high and the cost is average.

Dry seal pipe threading means that the thread itself is sealed (without the help of media). Seal pipe threads are mostly used in high-temperature, high-pressure systems and lubrication systems. Threading inspections are very demanding. The processing requirements are high and the cost is high.

The G thread is an unsealed pipe thread, and there are internal threads and external threads, and the RP must be an internal thread, which belongs to the sealed pipe thread.

rc is a sealed cone thread and is certainly an internal thread, and you say that the cone external thread rc1 2 is a wrong statement.

RP can be used instead of G (although it is a bit overkill), but G should never be used as a substitute for RP thread.

The Thread Handbook, 3rd Edition, 622 pages, read it for yourself, and you will definitely be able to clear up your doubts.

Inch sealed cylindrical pipe threads (internal threads) are often used in conjunction with sealed conical pipe threads (external threads). The pitch is the same as 11 teeth per inch, i.e. Due to the high requirements of RP thread on the accuracy of the tooth profile, the bottom hole should be appropriately reduced, and it is recommended that the bottom hole be beaten separately.

Summary. Pro, R stands for a series of threads, which is the code name for the thread of the inch seal pipe, with a tooth angle of 55 degrees.

P1 refers to the conical male thread used with a cylindrical female thread.

P2 refers to the conical male thread used for use with the conical internal thread.

RP1 RP2 in threading refers to how big the threaded hole is and what is the pitch.

Pro, R stands for a series of threads, which is the code name of the inch seal pipe thread early disassembly, and the tooth angle of 55 degrees P1 refers to: the conical external thread used with the internal thread of the round finger opening column P2 refers to: the conical external thread used with the conical inner spiral only chain.

RP1-1 2 How big is the threaded bottom hole.

Hello dear, the size of the RP1-1 2 threaded bottom hole refers to the size of its inner diameter. According to the thread standard, the inner diameter of the RP1-1 2 thread is mm. It should be noted that the size of the threaded bottom hole is determined according to the standard of the thread, so it is necessary to understand the specifications and standards of the thread when choosing the threaded bottom hole to ensure that the appropriate bottom hole size is selected for selection.

Summary: The size of the bottom hole of the RP1-1 2 thread refers to the size of its inner diameter, according to the thread standard, the size of the inner diameter of the RP1-1 2 thread is mm. When choosing a threaded bottom hole, you need to know the specifications and standards of the thread to ensure that you choose the right bottom hole size.

I'm glad to answer for you, and I hope I can help you. If my answer is helpful to you, please give a thumbs up, I look forward to your praise, your efforts are very important to me, and your support is also the driving force for my progress. Best wishes again good health and a good mood!

With a diameter size of 1 8 inches, the RP2 thread is the standard thread in thread gauges and is widely used in a variety of mechanical and industrial applications. A thread gauge is a tool used to measure threads, often used to determine the size and specification of threads.

In mechanical engineering and industry, accurate measurement of thread dimensions is very important. The thread gauge is a popular tool because it can easily measure subtle differences and very small dimensions. The R-Series thread gauges, including the RP2 thread gauge, are one of the thread gauges that are frequently used in the manufacturing industry.

Further, the RP2 thread gauge is for a specific thread size, which is 1 8 inches. Specifically, the RP2 thread gauge refers to the standard imperial thread specification, which is often used in piping and pneumatic systems, and is widely used in many industrial applications. For example, many pneumatic tools, such as air-hydraulic drill rigs, clamps and pneumatic welding equipment, commonly use RP2 thread gauges.

If you need to use threads of other thread sizes, such as M-series thread gauges, you need to use a different thread gauge measuring tool for measurement. Thread specifications may vary from country to country or region, so you need to be mindful of the thread specifications used in a particular region.

In summary, the RP2 thread gauge has a diameter size of 1 8 inches, and it is a common thread specification that is widely used in machinery manufacturing and industrial applications. <>

Standard hole, the largest hole diameter, the smallest.

RP1-2 1 is a cylindrical internal thread mated with a conical external thread, and 1-1 2 is the inner bore diameter of the pipe thread, which is about inches.

A thread is a helical continuous raised part with a specific cross-section made on the surface of a cylindrical or conical matrix. Threads are divided into cylindrical threads and tapered threads according to their parent shape; According to its position in the matrix, it is divided into external thread and internal thread, and according to its cross-sectional shape (tooth shape), it is divided into triangular thread, rectangular thread, trapezoidal thread, zigzag thread and other special shape threads.

RP - Inch straight pipe internal thread (connected with the cone pipe external thread R thread),

1-1 2 is the inner bore diameter of the pipe thread, which is about 1-1 2 inches.

RP2 is a kind of pipe thread sealed with thread, which is a cylindrical internal thread, and the specific basic size of 60° sealing pipe thread is GB T12716-2002.

RP is a cylindrical internal thread, R is the code of the cone external thread (but must add a foot mark 1 or 2), it is really good, but: R1 is matched with RC cone internal thread, for example, R2 1 4 is matched with RC 1 4 (note that the previous 1 is a foot mark) and RP cylindrical internal thread is R2, for example, with RC 1 4 is R1 1 4 (note that the first 1 is a foot mark). The GB T medium paragraph states:

rp—represents a cylindrical internal thread; r1—Indicates a tapered external thread mated to a cylindrical internal thread.

It's the same as threads, but with a slight difference in tolerance.
