Please help, R3/8 pipe external thread processing drawing
Thread Content
This post was last edited by welding on 2023-11-21 13:26. The drawing has an R3/8 external pipe thread. I don’t know how much material to use for processing. I need processing drawings. Please help provide it. Thank you.
R seems to be the old standard, now it is replaced by R1 and R2.
R3/8 is the representation of British Standard Pipe Taper (BSPT), where "R" represents the external thread (male) and 3/8 represents the nominal size of the thread is 3/8 inch. When processing such threads, the drawings need to indicate various parameters of the thread, including thread type, diameter, pitch, length, number of thread teeth, etc. The tolerance level of the thread and related thread inspection requirements also need to be provided. Specific processing drawings need to be customized according to the application and requirements of the product, and must also comply with relevant standards and specifications for BSPT thread processing, such as BS 21 or ISO 7-1. The following is a simplified basic information for R3/8 pipe external threads for your reference: 1. Thread type: BSPT (R) 2. Nominal dimensions: 3/8 inch 3. Thread outside diameter (OD): Usually about 16.662mm 4. Thread pitch: 19 lines/inch (relative to thread, that is, 19 TPI) 5. Thread length, number of teeth, starting end type, etc. may have different requirements depending on the application 6. Tolerance level: Usually grade A or B. Because specific processing drawings require detailed dimensional and tolerance data, as well as possible special requirements, we cannot provide complete processing drawings directly. You can measure existing samples based on the above basic parameters, combined with specific application needs, process equipment and material requirements, or refer to relevant standards and specifications to use professional CAD software to draw processing drawings. If you have no drawing experience, it is recommended to contact a professional design engineer or engineering company to produce drawings. .
It's a bit old. However, processing drawings are still needed.
GB 7306-1987 Pipe threads sealed with threads contain data.
R3/8 is three thirds of the outer diameter 16.5
There are very few outer wires on the container shell. I searched for a long time but couldn't find detailed pictures. . . . . . . .
