Hi Ven, Common practice, in the absence of any references, is to assume the mill tolerance for wall thickness for seamless piping to be 125% This is, in fact, the figure quotedMill tolerance cannot exceed 125% t min = 0875 x t nom for example t nom is 0300" (762mm) t min is 0262" (665mm) So, depending on how pipe is ordered in the PO orMill Tolerance ASME (mechanical) Code Issues EngTips

Pipe tolerances will depend on the alloy and the standard to which it was produced The general requirement standard covering most stainless pipe is ASTM/ASME A/SA 999 The OD under tolerance on all sizes is 0031” TheLocation of attachments etc, shall not exceed 3 mm (Tolerance shall be cumulative) B For Piping Bends having a radius equal to SIX times the diameter or larger variations in theTolerances for Pipe Fabrication wermac

This specification provides the requirements for under tolerance of pipe wall (125%) and OD variations based on the NPS designator The answer to your second questionNominal Pipe Diameter Pipe Size Pipe Schedule Thickness of pipe Mechanical Allowances This includes material removed from threading and corrosion allowances MillASME B313 Pipe Thickness Calculator Piping Designer

Weight tolerance For pipe NPS 12 (DN300, 3238mm) and under, the weight shall vary within 35% / +10% For pipe over NPS 12 (DN300, 3238mm), the weight shall vary within 5% /Extruded Tube Tolerances Chicago Tube & Iron The tolerance for the width is the value in the previous column for a dimension equal to the depth and conversely, but in no case is the tolerance less than at the corners Example: The width tolerance of a 1 x 3 inch alloy 6061 rectangular tube is ±0025 inch and the depth tolerance ±0035 inchmill tolerance of pipe ocean2oceanaccommodationafrica

Hi Ven, Common practice, in the absence of any references, is to assume the mill tolerance for wall thickness for seamless piping to be 125% This is, in fact, the figure quoted by ASTM A53 a standard which incidentally applies to both seamless and welded pipe This means that the piping wall thickness may vary by 125% or, stated differently, the ratio of the thinnestGood Answer: I think the answer is NO to either version, under any reasonable interpretationPipe Mill Tolerance and Required Reinforcement

Commercial product for 28” size is welded pipe(EFW) but A335 is for seamless pipe Mill tolerance for A335 is 125% max in the ASTM Your pipe is probably specially ordered pipe with extra money The best idea is to make separate runs as Edward suggested I assume;no CA in your serviceno –mill tolerance from vendorAmong the low alloy materials, this kind of material is the most common The outer diameter of hotrolled seamless pipe is generally greater than 32mm, the wall thickness is 25200mm, the outer diameter of coldrolled seamless steel pipe can be 6mm, the wall thickness can be 025mm, the outer diameter of thinwalled pipe can be 5mm, and theSeamless Steel Pipe Wall Thickness Tolerance
