Tolerances of pipes you should notice

Take seamless steel pipe as an example, there are some tolerances that affect quality. Noting this, and you will get a better pipe.

Weight tolerance

For pipe NPS 12 (DN300, 323.8mm) and under, the weight shall vary within -3.5% / +10%.

For pipe over NPS 12 (DN300, 323.8mm), the weight shall vary within -5% / +10%.

Pipe of NPS 4 (DN100, 114.3mm) and smaller may be weighed in convenient lots; pipe in sizes larger than NPS 4 shall be weighed separately.

Quantity tolerance

Normally mills take -10% to +10% tolerance, but TPMCSTEEL keeps ±3% variation.

Length tolerance

For Seamless pipe& tube, if definite cut lengths are ordered, the length shall vary within -0mm / +6mm.

Dimension tolerances of seamless steel pipe

Chemical composition

Steel is an alloy of iron and other elements. Some elements are intentionally added to iron for the purpose of attaining certain specific properties and characteristics. Other elements are present incidentally and cannot be easily removed. Such elements are referred to as “trace” or “residual” elements.

Many product specifications have mandatory requirements for reporting certain elements and these vary. Most mills routinely provide heat analysis which includes the elements below. Although it is possible to analyze for other elements this is most often not practical or necessary unless they are additions (e.g. Pb – Lead, Sb – Antimony or Co - Cobalt).
