1. Safety information
Safe operation of these products can only be guaranteed if they are properly
installed, commissioned, used and maintained by qualified personnel (see
Section 1.11) in compliance with the operating instructions. General installation and
safety instructions for pipeline and plant construction, as well as the proper use of
tools and safety equipment must also be complied with.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, product markings and
Technical Information Sheet, check that the product is suitable for the intended
use / application. These products comply with the requirements of the European Pressure
Equipment Directive 97 / 23 / EC and all fall within category 'SEP'. It should be noted that
products within this category are required by the Directive not to carry the mark.
i) These products have been specifically designed for use on steam, air or
condensate / water, which is in Group 2 of the above mentioned Pressure
Equipment Directive. The products' use on other fluids may be possible but, if
this is contemplated, Spirax Sarco should be contacted to confirm the suitability
of the product for the application being considered.
ii) Check material suitability, pressure and temperature and their maximum and
minimum values. If the maximum operating limits of the product are lower than
those of the system in which it is being fitted, or if malfunction of the product
could result in a dangerous overpressure or overtemperature occurrence, ensure
a safety device is included in the system to prevent such over-limit situations.
iii) Determine the correct installation situation and direction of fluid flow.
iv) Spirax Sarco products are not intended to withstand external stresses that may be
induced by any system to which they are fitted. It is the responsibility of the installer
to consider these stresses and take adequate precautions to minimise them.
v) Remove protection covers from all connections, where appropriate, before
installation on steam or other high temperature applications.
1.2Access
Ensure safe access and if necessary a safe working platform (suitably guarded)
before attempting to work on the product. Arrange suitable lifting gear if required.
1.3Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
1.4 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some previous
time. Consider: flammable materials, substances hazardous to health, extremes of
temperature.
1.5 Hazardous environment around the product
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases,
extremes of temperature, hot surfaces, fire hazard (e.g. during welding), excessive
noise, moving machinery.
1.6 The system
Consider the effect on the complete system of the work proposed. Will any proposed
action (e.g. closing isolation valves, electrical isolation) put any other part of the system
or any personnel at risk?
Dangers might include isolation of vents or protective devices or the rendering ineffective
of controls or alarms. Ensure isolation valves are opened and closed progressively to
avoid system shocks.
2
IM-P128-13 ST Issue 2
1.7 Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure. Consider
double isolation (double block and bleed) and the locking or labelling of closed valves.
Do not assume that the system has depressurised even when the pressure gauge
indicates zero.
1.8Temperature
Allow time for temperature to normalise after isolation to avoid the danger of burns.
1.9 Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables available.
Use only genuine Spirax Sarco replacement parts.
1.10 Protective clothing
Consider whether you and / or others in the vicinity require any protective clothing to
protect against the hazards of, for example, chemicals, high / low temperature, radiation,
noise, falling objects, and dangers to eyes and face.
1.11 Permits to work
All work must be carried out or be supervised by a suitably competent person.Installation
and operating personnel should be trained in the correct use of the product according
to the Installation and Maintenance Instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where there
is no such system, it is recommended that a responsible person should know what
work is going on and, where necessary, arrange to have an assistant whose primary
responsibility is safety.
Post 'warning notices' if necessary.
1.12Handling
Manual handling of large and / or heavy products may present a risk of injury. Lifting,
pushing, pulling, carrying or supporting a load by bodily force can cause injury
particularly to the back. You are advised to assess the risks taking into account the task,
the individual, the load and the working environment and use the appropriate handling
method depending on the circumstances of the work being done.
1.13 Residual hazards
In normal use the external surface of the product may be very hot. If used at the maximum
permitted operating conditions the surface temperature may reach temperatures in
excess of 425°C (797°F).
Many products are not self-draining. Take due care when dismantling or removing the
product from an installation (refer to 'Maintenance instructions').
1.14Freezing

Fig. 1 The PC10HP has been designed for use with the above listed steam trap options
2.1 General description
The PC10HP pipeline connector is designed for use with the above listed swivel connector
steam traps up to the maximum pressure / temperature limitations of the selected steam trap. The
connector can be fitted into any vertical or horizontal pipeline and the trap can also be rotated
through 360º to ensure their correct orientation for operation.
The principle is that the pipeline connector can be fitted into the pipeline without the trap fitted
and the trap is connected afterwards using just two bolts. The trap can be simply and quickly
removed / replaced to minimise system downtime and reduce maintenance resource.

3. Installation
Note: Before actioning any installation observe the 'Safety information' in Section 1.
There are a number of criteria which must be satisfied to ensure that the swivel connector
trap will operate correctly and ensure effective condensate removal. Referring to the
Installation and Maintenance Instructions, product markings and Technical Information
Sheet, check that the product is suitable for the intended installation:
3.1
Check materials and maximum pressure / temperature values. If the maximum operating
limit of the product is lower than that of the system in which it is being fitted, ensure
that a safety device is included in the system to prevent overpressurisation.
3.2
The correct steam trap and end connection must be selected to meet the system design
conditions.
3.3
3.4
Steam trap connector bolts are supplied with the selected steam trap.
3.5
Determine the correct installation situation and direction of fluid flow. The PC10HP
must be installed with flow in the direction of the arrow. Flow can be horizontal (either
direction), vertical or inclined. The flow direction is clearly marked on the trap body
or pipeline connector.
Caution: The connection face for the swivel connector steam trap of choice must
always be in the vertical plane unless stated on the product specific steam trap
Installation and Maintenance Instructions provided with the product.
The joint between the PC10HP and trap is sealed with high integrity spirally wound gaskets.
During installation the gasket faces must be protected from damage caused by weld
splatter, knocks, etc.. to the trap gasket face. Hence care must be taken when installing
the PC10HP into the pipework. It is recommended that the trap is installed immediately
the PC10HP is in the pipework. Alternatively, the trap can be joined to the PC10HP prior
to installation.
3.6 Remove
protection covers from all connections, where appropriate, before
installation on steam or other high temperature applications.
3.7
Suitable isolation valves must be installed to allow for safe maintenance and trap
replacement.
Where the trap discharges into a closed return system a non-return valve should be
fitted downstream to prevent back flow.
3.8
Always open isolation valves slowly until normal operating conditions are achieved –
this will avoid system shocks. Check for leaks and correct operation.
3.9
Always ensure the correct tools, safety procedures and protective equipment are
used at all times.
3.11When a socket weld version is being installed the welding should be carried out to
an approved procedure of a recognised standard. Guidance instructions regarding
welding socket weld versions are provided in Section 3.12
Notes:
1. If the trap is to discharge to atmosphere, ensure that it is to a safe place. The discharging
fluid may be at a temperature of 100°C (212°F).
2.After installation it is recommended that the PC10HP pipeline connector is insulated to
minimise radiated heat losses and to protect personnel from burns risk. Please note that
there are some trap types that should not be insulated.

3.12 Welding into pipeline of socket weld variants
A universal weld procedure covering the requirements of different national and international
standards and practices is difficult to provide - specifically regarding the welding procedure, welding
conditions (run number, consumable size, current, voltage, polarity), storage of consumables
and make / type of consumables due to the abundance of appropriate consumable suppliers.
Therefore, this is only advice based on British standards to be used for guidance on the essential
requirements of welding socket weld pipeline connectors into the pipeline.
This will allow a user to select an appropriate weld procedure from those available to that user.
This advice is not intended to be a substitute for a weld procedure: it is for guidance only.
