DUCTILE IRON FABRICATED FLANGED PIPE
SCP can manufacture any configuration of Ductile Iron fabricated flanged 
pipe to suit your specific requirements in nominal bore 80mm - 800mm and 
up to a maximumlength of 5.2M.
All fabricated pipework is manufactured using K9 barrel as standard.

This service is particularly useful where pressure pipelines are installed above
ground such as water treatment plants, pumping stations and where flanged
pipe is needed to be made to exact lengths.

Where pipes need to be cast in concrete walls such as inlet and outlet 
pipework, AiFu can apply a fixed puddle flange to any configuration of pipe.

This facility is available in both standards EN 545 for potable water and 
EN598 for sewage and wastewater applications. Standard Flange Drilling is
PN16, but other variations are available.

DUCTILE IRON SOCKETED FITTINGS
The Ductile Iron Socketed joint is favoured for
below ground pipelines such as distribution 
mains and sewage line applications.

Quick and easy to install, requiring no special
backfill the socket spigot joint is capable of 
angular deflection and longitudinal withdrawal 
without loss of performance. Other advantages 
are high strength for assured security, able to      Click image for technical data 
operate at 60-bar pressure (Depending on 
Nominal bore).

All pressure pipelines with this type of joint may require restraint particularly 
where a change of direction or the blanking off of an end occurs, in these
instances the use of a concrete thrust block is common practise.

All Fittings are supplied with EPDM rubber sealing gaskets and comply fully 
to BS EN 545:2002 for potable Water and EN 598 for sewage and wastewater 
applications.  Standard corrosion protection is as stated in these standards, 
however other coating options are available on request.

DUCTILE IRON FITTINGS TO SUIT 
METRIC PVC PIPE
The SCP range of Ductile Iron fitting to suit 
Metric PVC pipe are available in sizes to suit 
63mm–315mm o/d PVC pipe. A simple socket 
type joint, it is quick and easy to install 
without requiring jointing force. The fittings
come ready to install with an EPDM gasket 
already fitted in each socket.
                                                                                   Click image for technical data
This range of fittings is particularly competitive
when compared to manufactured PVC options.
 
The standard corrosion protection system is Blue Plascoat PPA571 to 250 
microns, complying fully with BS 6920 and WRAS approved for use in potable
water pipelines.

The range fully complies with DIN 16 451:1994.

DUCTILE IRON MECHANICAL JOINT FITTINGS
The SCP Mechanical Joint system is suitable 
where future dismantling of the pipe system
is a design requirement. Available in sizes 
80mm - 400mm NB the system allows for 
assembly without requiring jointing force to
be applied and offers angular deflection. The
standard corrosion protection system is Blue 
Plascoat PPA571 to 250 microns, complying
fully with BS 6920 and WRAS approved for            Click image for technical data
use in potable water pipelines.

All fittings come complete with all jointing materials.

DUCTILE IRON ROTATING FLANGE FITTINGS
In addition to our range of fixed flange fittings
SCP offers fittings with an adjustable rotating
flanges. Available in sizes 80mm - 300mm NB. 
The working pressure of the rotating flange 
fitting is the same as the standard fixed flange
option, but with additional advantages:

1  Ease of assembly 
2  Flexibility to orientate the pipeline on site         Click image for technical data
3  Adjustment without the need of restrained
    flange adaptors
4  100% hydrostatically factory tested
5  Interchangeable flange drillings

The standard corrosion protection system is blue Plascoat PPA571 to 250 
microns, complying fully with BS 6920 and WRAS approved for use in potable
water pipelines. The range complies fully to the dimensional and pressure 
test requirements of EN 545 : 2002.  All fitting dimensions are as series B.


HYDRO FLANGE ADAPTORS & COUPLINGS
Hydro Flange Adaptors 
Flange Adaptors are used to join a plain-ended pipe to a flanged pipe, fitting
or valve giving an effective leak proof seal. They can accommodate a 
considerable amount of deflection without loss of performance.

Harnessed flange adaptors used in conjunction with a flange spigot 
(complete with a tie flange) are an excellent method for providing a 
dismountable joint in a flanged pipeline. This is achieved by replacing four of
the bolts with tie studs. Where necessary the backing ring of the flange 
adaptor is notched to give clearance for the tie studs. 
               
Hydro Couplings
Couplings are used to join plain-ended pipes of the same material together; 
some wide tolerance couplings can join different pipe materials. Couplings 
offer a considerable amount of deflection, which makes them the ideal choice
for underground applications.

The Aifu ‘HYDRO’ Range of Flange Adaptors and Couplings are manufactured
to the highest standards and coated in Plascoat PPA571, this system
complies fully to BS 6920 and is WRAS approved for use with potable water,
offering easy and reliable pipe jointing with a durable long lasting corrosion
protection system. 

The ‘S’ range of Flange Adaptors & Couplings are available in sizes to suit 
80mm-300mm NB pipes these are a mid range product suitable for PVC, Steel
and Ductile Iron pipes. For sizes above 300mm NB we offer a dedicated range
to suit Ductile Iron pipe only these are available in sizes 350mm-700mm. 
Standard flange drilling is PN16. 

The HY range of Hydro Flange Adaptors and Couplings have a wide range and
will accommodate most pipeline materials. They are available in sizes to suit
50mm-300mm NB pipe. 

Hydro Resilient Seat Gate Valve offers quality and reliability along with high
performance. The valve has full WRc approval, and the EPDM rubber seat is 
BS 6920 approved. The watertight seal make this valve perfect for all 
potable and clean water pipeline applications. Hydro Resilient Seat Gate 
Valves are 100% factory tested to the requirements of BS 5163-Body test 
at 1.5 x PN, Seat tested from both sides at 1.1 x PN. The standard internal 
and external corrosion protection system is WRAS and DWI approved Plascoat
PPA571 to 200 microns.

SCP STAINLESS STEEL SADDLES
Made to the highest standards SCP Stainless Steel
saddles are the ideal way to take a service
connection from an existing or new water 
distribution main. The product is suitable for use
on any type of pipeline material.

The saddle, straps and bolts are manufactured
entirely of grade 304 stainless Steel.  All 
internal surfaces are bonded with WRAS                Click image for technical data
BS 6920 approved Nitrile rubber suitable for all 
potable water applications. The rubber lining means that none of the stainless
steel is in direct contact with the with the pipe ensures a firm none slip grip on
the mounting pipeline, as well as a perfect watertight seal around the outlet
at up to 16 Bar pressure.

The saddles are available with one or two straps depending on the size of 
the outlet required, or the diameter of the mounting pipe.

Single Strap for pipe sizes 50mm-600mm NB 
The finger bracket saddle incorporate a female threaded sleeve to
accommodate the securing bolt, which means that only a single access point
is required when fixing the saddle into position on the pipe. The stainless 
steel runs on a Delrin washer and the thread is coated in blue Teflon to 
prevent seizure.

Double Strap for pipe sizes 600mm-1000mm NB
On the double strap option the finger bracket saddle has a stainless steel
threaded rod welded to it, again the thread is blue Teflon coated. To fit
the saddle the threaded rod is passed though the mating hole on the strap
and secured with a stainless steel nut and Delrin washer. 

Sizes 
The range is available in sizes to suit pipelines with a 50mm-1000mm 
NB with outlets from ¼-2½ inch BSP. Each saddle will accommodate
many different types of pipeline material, having a wide radial tolerance
of approximately 20mm depending on the diameter of the pipe.
