The ASTM A106 Carbon Steel Smls Pipe actual size is difficult to achieve the nominal size requirements, that is, often greater than or less than the nominal size, so the standard provides that the actual size and the nominal size between the allowable difference.If the difference is positive, the deviation is positive; if the difference is negative, the deviation is negative.B. Tolerance: the sum of the positive and negative deviations specified in the standard is called tolerance, or "tolerance zone".Deviation is directional, that is, "positive" or "negative";Tolerances are non-directional, so it is a mistake to call the deviation a "positive tolerance" or a "negative tolerance".
The ASTM A106 Carbon Steel Smls Pipe length of deliveryThe delivery length is also called the length required by the user or the contract length.The standard has the following provisions for the delivery length:A, normal length (also known as non-fixed length) : where the length is within the length range specified by the standard and there is no fixed length requirement, it is called the normal length.For example, the standard provisions for structural pipes: hot rolled (extrusion, expansion) steel pipe 3000mm ~ 12000mm;Cold drawn (rolled) steel tube 2000mmm ~ 10500mm.
