PIPE FITTINGS

Introduction
Crane pipe fittings have been produced in the Ipswich Works since 1928 and
today the plant is one of Europe’s most modern units for large volume production
of malleable iron pipe fittings. It is renowned for its rigid enforcement of stringent
quality control procedures and inspection at all stages of manufacture.
The Crane trademark, coupled with the British Standards Institution Kitemark and
other quality assurance scheme approvals ensures that Crane fittings are fully
suitable for a wide range of applications and will give reliable service.

Crane Taper Thread Pipe Fittings

Pipe threads on Crane Pipe Fittings are British Standard taper to BS EN
10226-2 which replaces BS21 (ISO7-1) unless otherwise stated.
Crane Taper Thread Fittings offer installers numerous advantages over
equivalent fittings with parallel threads:

• Full engagement the whole thread length -

reliable strong joints
• No need for hemp filler -
faster installation, lower costs
• High torques can be applied without risk of
damaging the fitting
• Freedom to break and re-make joints
• Professional joint appearance

Crane Taper Thread fittings provide the most effective

jointing solution

Pipe threads
The machined threads of Crane fittings are supplied to conform with the gauging
requirements of BS EN 10226-2 and BS 21. Threads on all fittings are chamfered
to assist assembly and avoid ‘cross threading’. Female fittings have a chamber
behind the thread, permitting the male thread to be assembled without restriction
or ‘bottoming’.

Design standards
ISO 49 : 1994 is the international standard for "Malleable cast iron fittings
threaded to ISO 7-1. This standard was revised in December 1994 and, compared
with the 1983 edition, contained some technical revisions relating to use of
alternative ferrous materials, hot dip zinc coatings, dispatch condition,
pressure/temperature ratings, acceptance tests, marking and quality assurance.
BS EN 10242 : 1995 is the new British European Standard for "Threaded pipe
fittings in malleable cast iron" first published in August 1995 and very closely
follows ISO 49 : 1994, the main difference being the inclusion of two informative
annexes relating to "Assessment of conformity" and the "Relationship with the
essential requirements of the Construction Products Directive (84/106/EEC)".
All European Standards have to be adopted by the member countries of the EU
and any conflicting national standards withdrawn. BS143 and 1256: 2000 has
been retained to cover those fittings not in BS EN 10242. It should also be noted
that BS EN 10242 details a number of fitting types and sizes which were not
included in BS 143 & 1256 because they were not in regular demand and/or not
available from UK manufacturers. BS 143 & 1256 : 2000 specifies requirements for
the design and performance of "Malleable cast iron and cast copper alloy threaded
pipe fittings" and has developed over many years. BS 143 was first published in
1922 and BS 1256 in 1945, subsequently the two standards were combined in
1968. The BS 143 design requires fittings to have taper external threads and taper
internal threads conforming to BS EN 10226 whereas the BS 1256 design has
taper external threads and parallel internal threads. The 1986 revision was more
closely related to ISO 49 : 1983 and more accurately reflected the ranges of
fittings available from UK manufacturers. BS 143 & 1256 has always been
technically more demanding than ISO 49 and consequently BS EN 10242.
BS 143 & 1256 were amended in August 1995 to delete those fittings now
covered by BS EN 10242, so the scope of BS 143 & 1256 is now essentially : (a)
BS 143 design and BS 1256 design fittings in malleable iron not covered by BS
EN 10242, (b) BS 143 design fittings threaded to ANSI B1.20.1 (NPT) and (c) BS
143 design fittings made in cast copper alloy (bronze) material.

Conformance of Crane fittings

Both malleable iron and steel fittings have been verified by the British Standards
Institute (BSI) as conforming to BS EN 10242 and BS143 & 1256, as appropriate,
and as such are permitted to bear the British Standards Kitemark Logo - Kitemark
Licence No. KM00382.

Some small size fittings are manufactured in steel and will conform to BS EN 10241.

Crane malleable iron fittings also have the approval of the Loss Prevention
Certificaton Board (LPCB) for use in sprinkler systems.

The Pressure Equipment Directive 97/23/EC (PED)

The Directive applies to the design, manufacture and conformity of pressure
equipment and assemblies of pressure equipment with a maximum allowable
pressure greater than 0.5 bar. Individual piping components, such as fittings, are
excluded from the scope of the Directive and therefore cannot
be CE marked. However Crane manufactured pipe fittings are

manufactured to the appropriate European standards and satisfy the essential

safety requirements of the PED.

website, or will be provided on request from Crane.

Piping installation
Compiled from British and International standards on Pipe Threads BS EN 10226
(supercedes BS21) and Pipe Fittings standards BS EN 10242, BS 143 & 1256
and ISO 49.
Much unnecessary labour and creation of random lengths of pipe might be saved
by the application of a few simple figures by the engineer when erecting the pipe
line. Generally the pipe line, section by section, is either accommodated within
fixed limits, usually the lines of building construction, or is fixed by prescribed
dimensions. Except in the case of a continuous run of piping connected either by
sockets or flanges, the engineer needs to know the length of pipe required to
make up between fixed positions of fittings prior to cutting and threading.
The diagram below and table of 'A' dimensions indicates the length of thread
engagement of BS EN 10226 taper pipe threads in nominal sizes 1⁄8 to 6 inch.
The approximate pipe length is calculated by using the expression
L = C - (B1 + B2) + 2A.

Designation of fitting size

The designation of fitting size for the fittings shown in this catalogue is as follows:
EQUAL FITTINGS: Equal fittings where all outlets are the same size are
designated by that one size, irrespective of the number of outlets.
UNEQUAL FITTINGS: Unequal fittings (reducing or enlarging) are specified by the
sizes of each outlet, the sequence being dependent on the number of outlets:
(a) For fittings having two outlets, the larger outlet is specified first.
Example: Fig. No. 145 hexagon reducing nipple with one end threaded size 2
and other end threaded size 1, is designated 2 x 1
(b) For fittings having more than two outlets. Crane uses BS EN 10242 method
(b) which gives the run as the first and second sizes of the designation and
the branch as the third size of the designation.
This is in contrast to BS EN 10242 method (a) which gives the run as the first
and third sizes of the designation and the branch as the second size of the
designation. This method is used in certain international markets. (Please see
the diagrams below for a visual explanation).
BS EN 10242 method (a) equivalents are specified in this catalogue where
applicable.

Malleable cast iron

Crane malleable iron is of the Blackheart type ideally suited to pipe fitting and
manufacture and conforms to BS EN 1562 Designation EN-GJMB-300-6, ASTM
A197 and ISO 5922.
Typical properties of Crane malleable iron are given in the table below, exceeding
the requirements in the above BS EN, ASTM and ISO standards.

Chemical Mechanical
composition Typical properties Typical
Total carbon 2.7% Tensile strength (N/mm ) 2
340
Silicon 1.75% Elongation on 36mm (%) 12
Manganese 0.69% Izod impact (room temp.) (J) 12
Sulphur 0.18% Brinell hardness 125
Phosphorous 0.02% Density (g/cm3) 7.56

The close relationship between the physical properties of test bars and actual
castings ensures design integrity and the preservation of high safety factors. Shock
pressures within pipe systems can be tolerated with complete safety.
The corrosion resistance of Crane malleable iron is good when compared with
grey cast iron and mild steel for most general applications including water, gas and
steam.

Crane bronze
Crane bronze has very good resistance to corrosion by aggressive waters, steam
and other fluids which promote dezincification in certain copper alloys. It is also
suitable for a wide range of temperatures.

Mild steel
BS143 and 1256 allow small size (3⁄8 and smaller) straight fittings to be supplied in
other ferrous materials e.g. mild steel as an alternative to malleable cast iron,
providing the mechanical properties are at least equivalent to the specified grade
of malleable iron.
Individual data pages state which Crane fittings are supplied in mild steel.

Galvanising
Where additional resistance to corrosion is required, malleable cast iron fittings
can be hot-dip zinc coated (galvanised) prior to machining. This process involves
coating the fittings with zinc which, in addition to its natural resistance to corrosion,
provides electro-chemical protection where the iron of the fitting is exposed by
damage. Mild steel fittings can be supplied with a proprietary zinc based coating.
The coating weight on Crane galvanised fittings conforms to the requirements of
BS EN ISO 1461 1998 and ASTM 153 with a minimum coating of 610 g/m2
(2oz/ft2) equal to a thickness of 86µm (0.0034 in). Average coatings are well in
excess of this and exceed the requirements given in BS EN 10242 and ISO 49.
When ordering galvanised or zinc coated fittings add the suffix ‘G’ to the figure
number.

Pressure/Temperature ratings
BS 143 & 1256 : 1986 states that fittings are for general purposes for the
transmission of fluids within the pressure and temperature ranges specified. The
ratings given are uprated from those in the 1968 edition, both for malleable cast
iron and bronze fittings.
The graph below shows the BS pressure temperature ratings. Crane malleable iron
and bronze fittings are suitable for use at these new ratings with the exception of
certain unions (see note Ø below), but such use is dependent on the suitability of
the connecting pipe material, the threaded joint and any thread sealants used. Due
consideration should also be given to any applicable codes of practice. Pressures
stated are maximum non-shock gauge.

Testing
Production testing: Meets requirements of BS EN 10242 or BS 143 and 1256 as
applicable. Type testing: In addition to production testing, all pressure containing
fittings are required by BS EN 10242, BS 143 & 1256 and ISO 49 to be designed
to withstand specified design test pressures and to be type tested accordingly -
100 bar (1450 lbf/in2) for sizes 4 and smaller malleable iron fittings, 64 bar (928
lbf/in2) for sizes 5 and 6 malleable iron and all sizes bronze fittings. Tests carried
out show that production fittings have safety margins well in excess of the BS
requirement. Some typical burst tests on Crane fittings illustrate their capabilities -
size 1⁄2 Fig. No. 193 bend tested to 550 bar (8000 lbf/in2) without failure; size 1 Fig.
No. 241 flat seat union tested to 248 bar (3600 lbf/in2) without failure; size 6 Fig.
No. 151 elbow tested to 190 bar (2750 lbf/in2) without failure.

Finish
All malleable iron fittings are given an oil finish as protection against rust while in
stock or during transit and after installation prior to plant commissioning. Finished
fittings are free of any polycyclic aromatic hydrocarbons.

Marking
All Crane fittings are marked with the logo and where size permits, the fitting
size and Kitemark symbol. In addition, some castings also display a pattern
identification number. This is normally located next to the band of the fitting. This
number is used during the manufacturing process as part of the rigorous quality
control procedures to ensure consistent high quality castings. The number is not
of relevance to the end user of the product.

THE CRANE SA (SELF ALIGNING) UNION

The Crane SA Union is made with double spherical
seats. Pipes which are not in alignment can be
securely connected at any angle up to 6° of arc
from centre line of the union, thus avoiding the
need for offsets. The union provides a pressure
tight joint without the use of gaskets or washers.

● Self aligning (SA) Union

● Double spherical seats
● Iron to iron seating
● Taper threads to BS 21 (ISO 7-1)
● Black or Galvanised

Taper Thread fittings

This sign means that the fitting is
manufactured in the UK by
Crane and has a taper
thread. This ensures the
fitting engages with the whole
thread of the pipe which is also
tapered giving a stronger, more
reliable joint without the need for
hemp filler.

Crane Fittings carry the signs to assure

you of the best of British manufacture.
