Tolerance:
In the manufacturing process, due to the influence of processing or measurement, the actual size of the finished product always has a certain error.
In order to ensure the interchangeability of parts, the actual size of the parts must be controlled within the allowable range. The allowable dimensional variation is called dimensional tolerance.
Cases:
1, the basic size design, given size: 30mm
2, the limit size allows two dimensional variations of the limit value:
Maximum limit size =30+0.01=30.01mm
Minimum limit size =30-0.01=29.99mm
3, the algebraic value of the limit deviation, the minimum size, and the basic dimension. That is, the algebraic difference between the maximum limit size and the minimum limit size and the basic dimension are the upper and lower deviations, collectively the limit deviations. The upper and lower deviations of the hole are expressed in capitals ES and EI, respectively:
Upper deviation ES=30.01-30=+0.01
Lower deviation EI=29.99-30=-0.01
4, dimensional tolerances allow the amount of variation in size, i.e., the maximum limit size, the minimum limit size, and the algebraic difference between the upper and lower deviations.
Dimensional tolerance is an absolute value without symbols.
Tolerance: 30.01-29.99=0.02
Or I0.01- (-0.01) =0.02
Type:
Straight through joint, straight joint, three way joint, elbow, live nut joint, hinge joint, plug head, transition joint, etc.
Double card sleeve assembly: front clamping ring, back clamping ring, nut
Materials are commonly made of stainless steel and carbon steel
Metric, American and British thread standard
NPT, PT, and G are pipe threads
NPT is the abbreviation of National (American) Pipe Thread, an American Standard 60 degree taper pipe thread, used in North America. National standards refer to GB/T12716-1991
PT is the abbreviation of Thread Pipe, is a 55 degree taper pipe thread sealing, belonging to the Whitworth family, for the European and Commonwealth countries. Commonly used in water and gas pipe industry, taper regulations of 1:16. national standard is available on the GB/T7306-2000
G is a 55 degree non thread sealing pipe thread, belonging to the family of Wyeth thread, marked G for cylinder threads. National standards refer to GB/T7307-2001
In addition, the 1/4, 1/2 and 1/8 marks in the thread refer to the diameter of the thread size, in inches
usually refers to the size of the thread by one point, one inch equals 8, and 1/4 inches is 2, so by analogy
G is the pipe thread collectively (Guan), 55, 60 degrees division is functional, commonly known as tube round. The thread is machined from a cylindrical surface.
ZG is a commonly known as cone, cone thread processing, pipe joint is generally the domestic old standard thread marked Rc thread R
Metric threads are represented by pitch, and American and British threads are expressed in thread per inch. This is their greatest difference,
Metric thread is 60 degrees equilateral tooth type, thread is isosceles tooth type thread 55 degrees, 60 degrees.
Metric units for metric threads; British and American systems.
Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter.
1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
