BRIEF HISTORY
The IS0 Recommendation R 336, Plain End Steel Tubes, Welded or Seamless - General
Table of Dimensions and Masses per Unit Length, was drawn up by Technical Committee
ISOiTC 5, Pipes and Fittings, the Secretariat of which is held by the Association Suisse de
Normalisation (SNV).
Work on this question by the Technical Committee began in 1957 and led, in 1961, to the
adoption of a Draft IS0 Recommendation.
In August 1961, this Draft IS0 Recommendation (No. 461) was circulated to all the IS0
Member Bodies for enquiry. It was approved, subject to a few modifications of an editorial nature,
by the following Member Bodies :
Australia France New Zealand
Belgium Germany Norway
Greece Spain
Brazil
Burma Hungary Sweden
Czechoslovakia India Switzerland
Chile Israel United Kingdom
Denmark Italy Yugoslavia
Netherlands
Finland
One Member Body opposed the approval of the Draft: U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in September 1963, to accept it as an IS0 RECOMMENDATION.

IS0 Recommendation R 336 September 1963
PLAIN END STEEL TUBES, WELDED OR SEAMLESS
GENERAL TABLE OF DIMENSIONS AND MASSES PER UNIT LENGTH *
1. SCOPE
This IS0 Recommendation should be considered as a basic document for the preparation of
specific IS0 Recommendations. The diameters, thicknesses and masses per unit length for appro-
priate specifications (for example : for pipes and tubes for boilers, structural and mechanical
purposes, pipe lines, etc.) should be selected from this general table.
2. INTRODUCTION
The attached table gives the masses of plain end tubes in kilogrammes per metre and pounds per
foot, calculated in accordance with the method agreed already for IS0 Recommendation R 65,
Steel Tubes suitable for Screwing in accordance with IS0 Recommendation R 7. An explanation
of the method of calculation is given below. The corresponding diameters in millimetres and
inches are in accordance with IS0 Recommendation R 64, Steel Tubes - Outside Diameters. The
corresponding thicknesses in millimetres and inches are in accordance with IS0 Recommen-
dation R 221, Steel Tubes - Thicknesses.
The main purpose of this table is to serve as a ready reckoner and to avoid the possibility of different
countries putting forward different masses for a tube of the same nominal dimension. The inclusion
of a mass for a given sue of tube in this table, therefore, does not necessarily mean that such size
is available, although at some future date it may be.
Should the mass of a thinner or a thicker tube be required, it can be calculated by the method
given below.
This table does not apply to tubes primarily intended to be screwed in accordance with IS0 Recom-
mendation R 7, Pipe Threads for Gas List Tubes and Screwed Fittings where Pressure-Tight Joints
are made on the Threads (118 Inch to 6 Inches). The masses of such tubes, both screwed and plain
end, are given in IS0 Recommendation R 65.
* See also IS0 Recommendation R 64, Steel Tubes - Outside Diameters,
and IS0 Recommendation R 221, Steel Tubes - Thicknesses.

3. METHOD OF CALCULATION
The values to at least five significant figures have been calculated by the formulae given below:
for the metric system rn = (D-t) t * 0.024 661 5” kg/m . . . (A)
for the inch system rn = (0-t) t 10.681 42** Ib/ft . . . (B)
where
rn = mass,
D = specified outside diameter,
t = specified thickness.
The lb/ft value (B) is then converted to kg/m value (C) by multiplying it by 1.4882.
- (A) + (Cl
-
The mean value in kg/m (D)
2
If this value does not differ by more than 1.5 per cent from either (A) or (C), the tube dimensions
are considered to be “corresponding” *** and the value (D) is the agreed value for tubes of the
dimensions concerned, whether these dimensions be metric or inch. The mean value in kg/m
(D) is rounded to three significant figures.
The equivalent mean lb/ft value (E) is found by dividing the rounded value (D) by 1.4882. This
value (E) is then rounded to three significant figures.
The values given in the table are those of (D) and (E), If value (D) differs by more than 1.5 per
cent from either (A) or (C), the tubes are shown in separate columns.
* This coefficient takes into account a density equal to 7.85 kg/dm3.
** This coefficient takes into account a density equal to 489.6 lb/ft3.
*** The dimensions in millimetres and in inches, given in the tables, are considered to be “corresponding values”, although
some of them are not exact equivalents. In all cases, however, the dimensions ensure practical interchangeability.
