"'. stainless steel pipe fittings of nominal size and actual size of China Steel China Steel Harbor Harbor. China Steel China Steel Harbor Harbor Harbor Steel China Steel China Harbor.
A, stainless steel pipe fittings of nominal size: the name is specified in the standard size, is the users and manufacturers hope to achieve the ideal size is specified in the contract order size.
B, the actual size of stainless steel pipe fittings: the production obtained during the actual size, the dimensions are greater than or less than the nominal size. This is greater than or less than the nominal size of the phenomenon known as the deviation
.
"'. Stainless steel pipe fittings bias and tolerance
A, stainless steel pipe fittings deviation: in the production process, because the actual size is difficult to achieve nominal size requirements that are greater than or less than the nominal size, so the standard set forth in the actual size
Nominal size to allow a difference between. Difference is called the positive bias is positive, the difference is called negative bias is negative.
B, stainless steel pipe fittings Tolerance: standard requires positive and negative deviation of absolute value and is called tolerance, also called "tolerance zones."
Bias is directional, that is "positive" or "negative," said; tolerance is not directional, so the deviation is called "positive tolerance" or "negative tolerance," it is called is wrong.
"' delivery length of stainless steel pipe fittings
Delivery length or the length of the contract, also known as the length of user requirements. Standard delivery length on the following provisions:
A, stainless steel pipe fittings are usually the length (also known as non-cut-length): Where the length of the standard within the prescribed length and no fixed length request, are referred to as usual length. Such as structural pipe standard
B, stainless steel pipe fittings Length Length: Length length should be within the usual length, is required by the contract size of a fixed length. However, the actual operation are cut out is not absolutely definite length
May, therefore, the standard length of the cut-sets are allowed deviation.
