Thread eccentricity tolerance:
2A of the external thread and the thread of the modified 2B various elements, the concentricity of the joint
does not exceed the following limit
When the diameter is the largest and the largest diameter, the two thread elements must be concentric,
however, if the size is not round, the size is small, in the non round point, the diameter and diameter will
In the middle of the smallest, the largest diameter, the two elements of the total runout can not be greater
than the middle diameter tolerance;
The diameter of the largest, the largest diameter of the hour, the two elements of the eccentricity of the
full jump is not greater than the large diameter tolerance;
The diameter of the smallest, the largest diameter of the hour, the two elements of the total runout can
not be greater than the diameter of the tolerance tolerance
The smallest diameter, small diameter (minor diameter) the shortest, the two should be concentric, if the
path is not round or too large, the two elements of the total runout can not be greater than the size of the
The maximum diameter of the path, the shortest path, the two elements of the eccentricity of the total
runout should not be greater than the median diameter tolerance
When the diameter is the smallest, and the path is the largest, the full runout of the two elements can not
be greater than the path.
Dimensions and tolerances
The size of the table is the size of the surface treated
The tolerance of the six corners to the edge is in table 1A
Six angle diagonal size shall not be less than 1.092 times the nominal edge size
The six corners of the length of not less than 0.43 times the nominal size on the side.
The minimum size of the diagonal square is not less than 1.25 times the nominal size on the side of the
side length of not less than 0.75 times the nominal size on the side. The unlabeled tolerance should be
within + 0.016 '(+ 0.4mm);
Joint base (Fitting seat) and straight thread diameter concentricity must be controlled in 0.010 "(0.25mm).
Total runout (FIM) in addition to special requirements, should be in accordance with the aperture
tolerance tables in 1B tolerance; elbow, three links. Each end of four through the axis angle tolerances of
1/8~3/8Tube joints and 1 /8~1/4 cone pipe joint is 2.5 degrees;
1/2~2Tube connector and 3/8~2 taper pipe joint is + 1.5 degrees
In addition to the special requirements, the six angle to be on edge size of diameter 15~30 of chamfer,
tolerances for the +0/-0.016 "(0.4mm). Or as the design permits to the adjacent chamfer
The process should be joint production of high quality products to comply with the most economic way.
There is no burr, iron oxide, etc. may be using influence function, all of the sealing surface of the finish in
Our QC procedure:
As we had more than 5 professional and technical personal, they ensure 100% products checking.
1. Material checking: strictly control of material using, meet international requested standards;
2. semi-finished products inspection: product inspection before 100% finished ;
3. production line test: with work team or data engineer who will inspect matchines and lines at fixed
4. finished prodcuct inspection: quality and property test before products are plated zinc, packed and loaded.
